What is Cognizil? Liquid memory drops in 60 seconds
Cognizil is a liquid dietary supplement for memory support, taken as one 1 mL dropperful a day. A 1 fl oz bottle holds 30 servings. Each serving lists 7 mcg of chromium picolinate and a 15.47 mg blend of 21 herbs and amino acids, including ginseng, maca and L-tyrosine.
Quick answer
Cognizil is a liquid memory supplement. You shake the bottle and swallow one dropperful a day, so there is no capsule. A bottle is 1 fl oz and holds 30 servings. The panel names one amount outright: 7 mcg of chromium, 20% of the Daily Value. Everything else sits inside a 15.47 mg proprietary blend of 21 ingredients, and the law lets a blend print one total instead of each amount. That total is small next to the doses used in published research, and this page says so plainly. Packs cost $49 to $79 a bottle and carry a 180-day money-back guarantee.
Six bottles works out at $1.63 a day
The six-bottle pack of Cognizil costs $49 a bottle, which is $1.63 a day and the lowest daily cost on this site. The 180-day guarantee covers the whole supply, and no subscription is mentioned in the seller material.
The 180-day guarantee is long enough to cover the whole six-bottle supply. No subscription is mentioned anywhere in the material we were given.
Why people look for a memory support supplement like Cognizil
People look for a memory supplement like Cognizil when names or tasks slip on busy days. Cognizil is a daily liquid labeled for Advanced Memory Support. If your memory has changed in a way that worries you, see a clinician first.
Most people who go looking for a memory supplement are not worried about a diagnosis. They are worried about a name that would not come when they needed it, or a second trip back to the kitchen for a reason they had already forgotten.
Those moments cluster around a few ordinary things. Short sleep. A week with too much on it. Long stretches of screen work with no real break. Blood sugar that swings after a big lunch. None of that is memory loss. It is attention running thin, and memory looking worse as a result.
So the search starts. It usually starts at a difficult moment, which is exactly when a website is most likely to oversell. A supplement that keeps to a daily habit is a reasonable thing to try. A supplement sold as a fix for a failing memory is not, and no product on the US market is allowed to be sold that way.
This page exists to give you the label, the prices, the guarantee and every disclosure in one place, so the decision is yours and not a sales page's.
What is Cognizil?
Cognizil is a dietary supplement sold as liquid drops rather than capsules. The bottle holds 1 fl oz, which is 30 mL, and the panel counts that as 30 servings of 1 mL each.
The front of the label carries one claim: Advanced Memory Support. That is a structure and function claim, the kind US law allows a supplement to make. It is not a treatment claim, and the back of the label carries the required line saying so.
Inside, the formula splits in two. Chromium is declared on its own at 7 mcg. The other 21 ingredients are grouped into a proprietary blend weighing 15.47 mg in total. That group mixes herb extracts, such as ginseng, eleuthero, maca and green tea, with free amino acids, such as L-tyrosine, GABA and L-tryptophan.
The liquid is sweetened with stevia and xylitol and flavored with natural flavors and citrus extract. Potassium sorbate keeps it stable. Water is the base.
The 1 fl oz amber dropper bottle. Amber glass is used for light-sensitive liquids, which is also why the label tells you to keep it away from heat and light.
Why buy Cognizil from the official website?
Buying Cognizil here gives you a printed label, a named seller and address, a 180-day money-back guarantee and a lot number to match against your bottle. Six reasons are listed below, and none of them is a countdown timer.
Six reasons, and none of them is a countdown timer.
1
The label is the source
Every number on this site is read off the printed panel. Where the panel does not say, this site says not published rather than filling the gap.
2
A real guarantee window
180 days from the order date on the packs sold here. That is long enough to finish six bottles and still ask for your money back.
3
No subscription trap
Nothing in the material we were given mentions auto-billing, a rebill or a trial that turns into a charge. You buy a pack once.
4
A named seller and address
Cognizil Daily is the U.S. stocking partner for Cognizil. The office and the returns address are printed on every page of this site.
5
Lot and batch on record
This stock is lot COG-26/CO-1168 with certificate reference COG-1168-26-CO. You can match it against the base of your bottle.

How does Cognizil work?
Cognizil is one liquid dropperful a day. Its blend mixes adaptogen herbs such as ginseng, eleuthero and maca with amino acids such as L-tyrosine, GABA and L-tryptophan. No trial has tested the finished formula, so no result is promised.
Nobody has tested this exact blend, so no one can tell you how this bottle performs. What we can do is explain what each group of ingredients is understood to do, and point at the research we actually read.
Step one: a fixed daily habit
One dropperful, once a day, swallowed. A liquid absorbs without waiting for a capsule shell to break down. The bigger effect of a simple serving is that people keep taking it, and the reviews on this page repeat that point more than any other.
Step two: the adaptogen group
Ginseng, eleuthero, maca and astragalus are grouped as adaptogens, plants studied for how people cope with load. A 2024 meta-analysis in Phytotherapy Research found ginseng had some effect on cognitive measures. A controlled study of eleuthero found no added benefit over stress management training alone. Both results belong on this page.
Step three: the amino acid group
L-tyrosine is the raw material for dopamine and noradrenaline, and reviews suggest it helps most when someone is already stressed or short on sleep. GABA and L-tryptophan sit on the calm side. A 2020 review in Frontiers in Neuroscience found no human data showing swallowed GABA crosses into the brain, so treat that ingredient as unproven.
Green tea leaf extract is the one place on this label with a clear short-term signal. A 2025 review in Nutrition Reviews found L-theanine with caffeine produced small to moderate gains in attention tasks within two hours. Green tea carries both. What it does not tell us is how much of either is in 15.47 mg of blend.
Cognizil Ingredients: what is in each dropperful
Twenty-two ingredients are listed on the panel. One carries a number. Twenty-one sit inside the blend. Here are the eight worth knowing about, then the full list.
7 mcg
Chromium (as chromium picolinate)
The only ingredient on the panel with its own number. Seven micrograms is 20% of the Daily Value. Chromium works in the body's handling of blood sugar, and steady blood sugar is part of steady attention.
amount not published
Panax ginseng root extract
The most studied name on this label for mental work. Trials have looked at ginseng and attention, though results move around from study to study.
amount not published
Eleuthero root extract
Often sold as Siberian ginseng and grouped with the adaptogens. Human results for tiredness and concentration are mixed, and one controlled study found no added benefit.
amount not published
Maca root extract
A Peruvian root studied mostly for mood and energy scores rather than memory. The trials that showed anything used three grams a day of extract.
amount not published
Green tea leaf extract
Green tea carries both caffeine and L-theanine. That pairing is the part of this label with the clearest short-term attention evidence.
amount not published
L-tyrosine
An amino acid the body uses to build dopamine and noradrenaline. Reviews suggest it helps most when a person is already stressed, tired, or cold.
amount not published
GABA
A calming messenger in the brain. Whether swallowed GABA reaches the brain in people is still an open question in the research.
amount not published
L-tryptophan
The building block the body turns into serotonin and then melatonin. It sits on the calm side of this formula rather than the alert side.
What the Cognizil label prints and what the studies used
The Cognizil blend weighs 15.47 mg in total, which is about 0.74 mg per ingredient if shared evenly. Research doses for single herbs run from hundreds of milligrams to several grams a day, so the blend is small next to them.
The whole proprietary blend weighs 15.47 mg. Spread evenly across 21 ingredients that is about 0.74 mg each. Many are 20:1 concentrates, so 1 mg of extract stands in for roughly 20 mg of raw plant, which puts the blend in the range of 300 mg of plant material in total. Research doses for single herbs on this list run from hundreds of milligrams to several grams a day.
Research doses are the doses used in the cited studies, not a recommendation.
Ingredient
In one serving
Dose used in research we read
What that means
Chromium
7 mcg, 20% DV
The Adequate Intake is 35 mcg a day for men, 25 mcg for women (NIH ODS)
7 mcg is a fifth of the 35 mcg Adequate Intake; memory trials used larger supplemental amounts
Maca root extract
Inside the 15.47 mg blend
3 g a day of extract for 12 weeks (Pharmaceuticals, 2016)
Inside the 15.47 mg blend, so well under the trial amount
Panax ginseng

Inside the 15.47 mg blend
Theanine plus caffeine studies used tens to hundreds of milligrams (Nutrition Reviews, 2025)
Its share of the blend is not printed
L-tyrosine
Inside the 15.47 mg blend
Review doses are usually measured in grams, not milligrams
Inside the blend, below the gram-level doses reviewed
GABA
Inside the 15.47 mg blend
100 to 300 mg for sleep outcomes (Frontiers in Neuroscience, 2020)
Human evidence is still open at 100 to 300 mg
Eleuthero root extract
Inside the 15.47 mg blend
A controlled study found no benefit added to stress management training
One controlled study found no added benefit for this use
Two things are true at once. The blend is small. And the 20:1 concentrates mean the raw plant equivalent is larger than the milligram figure suggests. If you want a product matched to a published dose of a single herb, this is not that product. If you want a light daily liquid you will actually take, it may still suit you. We would rather you knew before buying than after.
Cognizil Supplement Facts: the full panel, read from the bottle
The Cognizil panel shows a 1 ml serving, 30 servings per container, chromium at 7 mcg (20% of the Daily Value) and a 15.47 mg proprietary blend of 21 ingredients. Lot COG-26/CO-1168 is printed on the bottle.

What are the benefits of Cognizil?
The label makes one claim: Advanced Memory Support. Everything below describes what the ingredient groups are studied for, or what the product is like to own. None of it is a promise about your results.
1
Built around one daily serving
One dropperful, once a day. No pill box, no split doses, nothing to swallow. The habit is the part most likely to stick.
2
A liquid instead of a capsule
Useful if capsules are hard to take. The drops go straight into the mouth and are swallowed.
3
Chromium with a real number
7 mcg, 20% of the Daily Value, printed on its own line. Chromium has a place in the body's handling of blood sugar.
4
Adaptogens studied for load
Ginseng, eleuthero, maca and astragalus are all studied in the context of stress and mental work. Results vary by study.
5
Amino acids on both sides
L-tyrosine leans alert. GABA and L-tryptophan lean calm. The formula does not push hard in either direction.
6
No stimulant load by design
Guarana and green tea do carry caffeine, but at a 15.47 mg blend the amount is small. This is not an energy product.
What Cognizil does not do
It does not treat, prevent or reverse any disease, including dementia and Alzheimer's disease. It is not a sleep aid, a weight product or a stimulant. It will not undo a bad night's sleep. If your memory has changed in a way that worries you or the people around you, that is a conversation for a clinician, not a supplement.
Cognizil pros and cons
Cognizil is easy to take and has a 180-day guarantee, but 21 of its 22 ingredients have no published amount. The blend is 15.47 mg, which is small next to research doses. Both lists are below.

Who is Cognizil for?
Cognizil suits adults who want one easy daily liquid and can wait four to eight weeks before judging it. It is not for anyone under 18, or anyone pregnant or nursing. The lists below show who should skip it.
Worth a try if these describe you, and worth skipping if the second list does.
Cognizil may suit you if
You forget capsules
A dropperful takes three seconds and needs no water. If a pill bottle has ever sat unopened on your counter for a month, the format alone is the reason to look.
You want one thing, once a day
There is no morning and evening split, no loading phase and no cycling instruction. One serving, one time, every day.
You are in your 40s to 60s
Every review the seller supplied came from someone between 42 and 65. That is who is actually buying this.
You can wait two months
The reported window is four to eight weeks. If you are comfortable spending $158 and judging it in October when you started in August, this fits.
You want the guarantee to be long
180 days is unusually generous for this category, and it is the strongest single thing this purchase has going for it.
You avoid sugar
Stevia and xylitol, not sugar. Zero calories per serving on the panel.
Skip Cognizil if
You are under 18, pregnant or nursing
The label rules all three out. This is not a judgement call, it is printed on the bottle.
You need a dose you can check
Twenty-one of twenty-two ingredients have no published amount. If that is a dealbreaker, and it is a fair one, buy a single-ingredient product instead.
You want something to happen this week
Nothing on this label is built for a fast effect, and the reviews say so plainly.
You take a blood thinner or diabetes medication
Ginseng, green tea, gymnema and chromium all touch those areas. Not a refusal, but a pharmacist conversation first.
Your memory has changed noticeably
A change that you or your family have noticed is a medical question. A supplement is not the right first step.
You are cutting caffeine
Green tea and guarana are both on the panel. The amount is small, but if you are sensitive it is still there.
How to take Cognizil: the daily dose for adults, from the label
To take Cognizil, shake the bottle, draw one 1 mL dropperful, place it in your mouth and swallow, once a day. The label names no time of day. Store the bottle away from heat, light and humidity.
Straight off the label. Nothing here is our own advice.
Shake the bottle
The label says shake well before each use. A blend of extracts in water settles, so this step matters more in a liquid than in a capsule.
Draw one dropperful
Squeeze the bulb and let the dropper fill to the line. One dropperful is 1 mL, and the bottle holds 30 of them.
Place in mouth and swallow
The label's wording exactly. There is no instruction to hold it under the tongue, and no instruction about food or water.
Same time every day
The label does not name a time. Picking one, and keeping it, is the part that decides whether a 30-day bottle actually lasts 30 days.
Store it away from heat and light
Keep away from heat, light and humidity to preserve freshness. A cupboard, not a windowsill and not the bathroom.
Do not exceed the recommended dose. Not for anyone under 18, or for pregnant or nursing women. If you have a known medical condition, speak to a physician before starting this or any supplement.
What form does Cognizil come in?
Cognizil is a liquid. It comes in a 1 fl oz amber glass bottle, 30 mL, with a rubber-bulb dropper built into the cap. There is no capsule, tablet, gummy or powder version in the material we were given.
Amber glass filters light. The label's storage line asks you to keep the bottle away from heat, light and humidity, which fits a plant-extract liquid that can degrade in a bright kitchen.
A liquid has two honest trade-offs against capsules. It is easier to swallow and easier to adjust, and it is also easier to over-pour, which is why the label sets a firm ceiling of one dropperful. It also means you taste it. Stevia, xylitol, natural flavors and citrus extract are on the panel for that reason.
Cognizil vs. other memory support supplements
Cognizil is a liquid with one dropperful a day and one published amount, chromium. Capsule nootropics often need two or three capsules, and single-ingredient products always show their dose. The table below compares format, amounts and guarantee.

If your priority is a dose that matches a study, a single-ingredient product will beat any blend, including this one. If your priority is one easy daily serving you will keep up with, a liquid like this has a real advantage.
A quick Cognizil check before you order
Read the first list with your own health in mind. If any line fits you, a conversation with your doctor or pharmacist comes before the first dropperful.
See your doctor or pharmacist first if
your memory has changed recently or keeps getting worse, or you have spells of confusion (MedlinePlus on memory loss)
you take a blood thinner, diabetes medicine, an antidepressant or a stimulant
you live with a medical condition or have surgery booked
you are under 18, pregnant or nursing, groups the label itself excludes
Confusion that comes on suddenly, slurred speech or weakness on one side needs emergency care: call 911 (MedlinePlus).

Cognizil Price: how much does it cost?
Cognizil costs $79 a bottle on the two-bottle pack, $69 on three and $49 on six, which is $2.63, $2.30 and $1.63 a day. Two bottles add $9.99 shipping; three or six ship free within the U.S.
Three packs, no single bottle. Prices are per bottle and the total is what you pay; the sales page also shows struck-through full prices, which this site leaves out.

Cognizil cost per day, and which pack to choose
Cognizil costs between $1.63 and $2.63 a day depending on the pack. Two bottles suit a first try because they cover the four to eight week window buyers describe. Six bottles give the lowest daily cost.
One bottle is 30 servings, so the arithmetic is simple.

Which pack we would actually suggest
Reviews on this page put the usual wait at four to eight weeks. Two bottles is 60 days, which just covers that window at the lowest total outlay of $158. That is the pack to start with if you have not tried it. The six-bottle pack is the better deal per day, and the 180-day guarantee covers every bottle in it, so it is a fair choice if you already know the product suits you. Three bottles is the one we would skip: it costs $49 more than two and saves only 33 cents a day.
Is Cognizil safe? Side effects and interactions
The label sets four limits. Do not exceed one dropperful a day. Not for anyone under 18. Not for pregnant or nursing women. If you have a known medical condition, talk to a physician first.
No side effects are printed on the label, and none were reported in the reviews we were given. That is not the same as none existing. This formula has not been through a published human trial, so nobody has counted them.
Three interactions are worth naming, because of what is on this panel. Green tea and guarana both carry caffeine, so if you are cutting caffeine or take a stimulant medication, that is a real overlap even at a small dose. Ginseng and green tea have both been studied for effects on blood clotting, so raise them if you take warfarin or another blood thinner. Gymnema sylvestre and chromium both touch blood sugar handling, which matters if you take insulin or a diabetes medication.
Xylitol is on the other-ingredients line. It is safe for people and toxic to dogs, so keep the bottle where a pet cannot reach it. The label already says keep out of the reach of children.
Show the Cognizil panel to your clinician or pharmacist
If you take a blood thinner, a diabetes medication, a stimulant, an antidepressant or any prescription at all, show the panel to your pharmacist before the first dropperful. It takes two minutes and it is the only interaction check that actually applies to you.
How long does Cognizil take to work?
There is no tested answer for this formula. What follows is the pattern in the reviews we were given, which is customer feedback, not a clinical result.
When
What buyers reported
What we can honestly say
Days 1 to 7
Little or nothing. The most common complaint is wanting more in week one.
Expect no change. Anything you feel this early is most likely the routine, not the formula.
Weeks 2 to 4
Some buyers called it fair at a month.
This is where the habit is either holding or already broken. Set a fixed time if it has slipped.
Weeks 4 to 8
The window most reviewers named for noticing anything at all.
Judge it here. This is also why the 60-day two-bottle pack is the sensible first purchase.
Beyond 8 weeks
Reordering before the last bottle was the repeat comment from five-star reviews.
If nothing has changed by now, the guarantee still has more than three months left to run.
No supplement is required to work in any time frame, and nothing here is a guarantee of a result. The only promise attached to this product is the money-back window.
Is this the official Cognizil website, and is Cognizil sold here?
Yes, Cognizil is for sale on this site. Cognizil Daily is the U.S. stocking partner for Cognizil. Add To Cart on this page sends you to the official order page.
A short list of checks tells you whether any supplement seller can be trusted, and this one can be tested against it. A trustworthy seller names itself: this one prints a company name, an office at 10 East 40th Street in New York and a separate returns address on Third Avenue. It publishes its refund terms: a 180-day window and the steps to use it. And it does not bill again: nothing in the seller's material mentions a subscription, a rebill or a trial that converts.
The points worth weighing are different and smaller. You may pay for a blend whose amounts you cannot check. You may find the dose too light to notice. You may have to pay return shipping to claim the guarantee. Those are all stated on this page before you buy.
The other risk is buying a copy. Prices far under $49 a bottle, a marketplace listing with no seller name, or a bottle that arrives without lot COG-26/CO-1168 on the base are all reasons to stop and check.

Cognizil complaints: what buyers say takes getting used to
The most repeated Cognizil complaints are a slow start, hidden ingredient amounts, no single bottle to try and return shipping paid by the buyer. Twelve percent of reviewers did not recommend it.
Twelve percent of reviewers did not recommend it. These are the points they raised, set out at the same size as the praise.
1
“Wanted more in week one”
The single most repeated criticism, and it appears in every four-star review we were given. Nothing on this label is built for a first-week effect, so it will not suit anyone who needs something to happen quickly.
2
A slow start overall
Reviewers put the window at four to eight weeks, which is most of a two-bottle pack. That is a long time to spend before you know.
3
You cannot see the amounts
Twenty-one ingredients share one 15.47 mg figure. You can read the panel end to end and still not know how much ginseng you are taking.
4
No single bottle to try
The smallest purchase is two bottles at $158. Other products let you spend a third of that to find out.
5
Return shipping is on you
The guarantee is long, but you pay to send bottles back and you are advised to use tracking. Factor that in.
6
No published trial on the formula
Every study cited on this page tested a single ingredient, usually at a much larger dose. None of them tested Cognizil.
Does Cognizil have a money-back guarantee?
Yes. 180 days from the order date on the packs sold here. Here is exactly how a refund works, including the parts that cost you something.
Keep your order email
It carries the order ID, and every step below needs it. If you have lost it, search your inbox for the order date before you write in.
Write to the seller inside 180 days
Email the Cognizil Daily inbox with your full name, the email you ordered with, and the order ID. Say that you want a refund under the guarantee.
Send the bottles back
Return to 880 Third Avenue, Floor 13, New York, NY 10022. You pay the return shipping, and you are advised to use a tracked service so the parcel can be traced.
Wait for the credit
The seller states 3 to 5 business days to issue the refund after your return is received, then a further 5 to 10 days for a card to show it.
Two honest notes. Return postage is not refunded, so a guarantee claim is never completely free. And 180 days from the order date means a six-bottle pack finishes on almost the same day the window closes, so do not leave the claim to the last week.
Our editorial score for Cognizil
The desk scores Cognizil 3.3 out of 5. It rates the dropperful format and the 180-day guarantee highly, and scores label transparency and dose against research low because only chromium has a published amount.
Scored against what the label and the seller publish, not against how it feels to take. We have not tested this product in a trial and we do not pretend to have.

Ingredient selection Sensible, well-studied names, even if the amounts are hidden.3.5
Ease of taking One dropperful a day, no water, no capsule.4.5
Price per day $1.63 to $2.63, which is mid-range for a daily blend.3.0
Guarantee 180 days, longer than most of the category.4.5
Buying clarity Prices, shipping and the seller are clear. Delivery speed is not.3.5
Customer feedback 4.7 out of 5 from 718 written reviews supplied by the seller.4.0
Overall3.3 / 5
A well-chosen list of ingredients in a format people will actually keep up with, sold with an unusually long guarantee, and held back by a small blend whose split is not printed. Buy it for the habit and the guarantee, not for the milligrams. How this score is set.

Cognizil FAQ: reviews, ingredients, price and safety
These answers cover Cognizil reviews, what is in the drops, how to take them, price, side effects, FDA status and the 180-day refund. Each comes from the printed label and the seller pages.
Twelve of the most asked. The full set sits on the FAQ page.
What do Cognizil reviews say?
Seller-supplied Cognizil reviews score 4.7 out of 5 from 718 written reviews, and 88% would recommend it. Most buyers describe a four to eight week window and liked the one-a-day serving. This site has not verified them, and no result is promised.
Is Cognizil sold as capsules or gummies?
No. Cognizil is sold as liquid drops rather than capsules or gummies. The 1 fl oz (30 mL) bottle comes with a dropper, and the serving is one 1 mL dropperful a day, 30 servings to a bottle.
Is there a Cognizil subscription, and does shipping cost extra?
There is no subscription. Shipping is $9.99 on the two-bottle pack and free within the U.S. on three or six bottles.
What is Cognizil?
Cognizil is a dietary supplement sold as liquid drops in a 1 fl oz amber bottle. The label claims Advanced Memory Support. One bottle holds 30 daily servings, and each serving lists 7 mcg of chromium plus a 15.47 mg blend of 21 extracts and amino acids.
What is in Cognizil, ingredient by ingredient?
Cognizil lists one dosed nutrient, 7 mcg of chromium picolinate, plus a 15.47 mg blend. The blend names maca, African mango, grape seed, guarana, eleuthero, astragalus, green tea, gymnema, forskohlii, cayenne, grapefruit seed, Panax ginseng, raspberry ketones, six amino acids such as L-tyrosine and L-carnitine, monoammonium glycyrrhizinate and GABA. Water, stevia, xylitol and natural flavors make up the liquid.
When is the best time to take Cognizil?
The label names no set time, so most people pick the morning. Guarana and green tea in the Cognizil blend carry natural caffeine, and a morning dropperful is easy to tie to something you already do, like breakfast. Take one dropperful once a day and do not exceed that.
How do I order Cognizil online in the U.S.?
Pick two, three or six bottles on this site and press Add To Cart, which opens the official Cognizil order page. Two bottles cost $79 each plus $9.99 shipping, while three ($69 each) and six ($49 each) ship free within the U.S. Every pack carries the 180-day money-back guarantee.
Is Cognizil legit?
Cognizil has a full printed label with a 7 mcg chromium amount and a 15.47 mg blend total, and it names its distributor as Cognizil, PO Box 12730, Ogden, UT 84404. The packs sold here carry a 180-day money-back guarantee. The blend does not show each ingredient amount.
How do I take Cognizil, and what is the dose for adults?
Adults take one 1 mL dropperful of Cognizil once a day. Shake the bottle well, draw one dropperful, place it in your mouth and swallow. Do not exceed one dropperful a day. It is not for anyone under 18, and the bottle should be kept away from heat, light and humidity.
How long does Cognizil take to work?
There is no tested answer for this formula. Seller-supplied reviews mostly describe a four to eight week window, and almost nobody reports anything in week one. No result is promised, and the 180-day guarantee covers the packs sold here.
How much does Cognizil cost?
Cognizil costs $79 a bottle on two bottles, $69 on three and $49 on six. That works out at $2.63, $2.30 and $1.63 a day. Shipping is $9.99 on two bottles and free on three or six, and there is no subscription.
Where can I buy Cognizil in the USA online?
You can buy Cognizil online on this site. Cognizil Daily is the U.S. stocking partner for Cognizil, and the Add To Cart buttons go to the official order page. Packs ship from the United States, free on three or six bottles. Check that your bottle shows lot COG-26/CO-1168 on the base when it arrives.
Can I buy Cognizil over the counter in stores or on Amazon?
Cognizil is ordered online: the Add To Cart buttons on this site lead to the official order page. The seller points to this online order path only, so no store or Amazon listing is named here. The 180-day money-back guarantee covers the packs bought here, and a marketplace seller's terms may differ.
Does Cognizil have side effects?
No side effects are printed on the label, and none appear in the reviews supplied, but this formula has no published human trial. Guarana and green tea carry caffeine. Stop and ask a doctor or pharmacist if anything seems wrong.
Is Cognizil safe in pregnancy, and who should avoid it?
This supplement is for adults aged 18 and over. The label rules out anyone under 18 and anyone pregnant or nursing. Anyone with a known medical condition should talk to a physician before starting it. Do not take more than one dropperful a day.
Does Cognizil interact with medication?
Ginseng and green tea have been studied for effects on blood clotting, so mention them if you take a blood thinner. Chromium and gymnema touch blood sugar, and L-tryptophan matters with antidepressants. Show the panel to your pharmacist first.
Is Cognizil FDA approved?
No. The FDA does not approve dietary supplements before they are marketed, so Cognizil is not FDA approved. The label says it is made in the USA in an FDA-registered facility. That describes the facility, not the product.
Does Cognizil have a money-back guarantee?
Yes. The packs sold here carry a 180-day money-back guarantee from the order date. Email the seller with your name, order email and order ID, then return the bottles to the New York returns address. Return shipping is paid by you.
Ready to try Cognizil?
