You’re looking up Cognizil’s ingredients because you want to know what is in the bottle before you spend money on it. The Supplement Facts panel lists 22 dietary ingredients: chromium at 7 mcg, plus a 15.47 mg proprietary blend that holds the other 21, with no separate amount for any one of them. Below you’ll find each ingredient as the label prints it, the human studies named for it, and what each study covers.
What is in each serving of Cognizil?
Cognizil’s maker describes one serving as one 1 ml dropperful, taken once daily, with 30 servings in each 1 oz (30 ml) bottle. The Supplement Facts panel shows chromium (as chromium picolinate) at 7 mcg, which the label lists as 20% of the Daily Value, and a proprietary blend of 15.47 mg.
The blend lists these 21 ingredients, as printed: Maca (Lepidium meyenii) Root Extract, African Mango (Irvingia Gabonesis) Seed Extract, Grape (Vitis vinifera) Seed Extract, Guarana (Paullinia Cupana) Seed Extract, Eleuthero (Eleutherococcus senticosus) Root Extract, Astragalus Membranaceus Root Extract, Green Tea Leaf Extract, Gymnema Sylvestre Leaf Extract, Forskohlii (Coleus forskohlii) Root Extract, Cayenne Pepper (Capsicum annuum) Fruit Extract, Grapefruit (Citrus Paradisi) Seed, Ginseng (Panax Ginseng) Root Extract, Raspberry Ketones, L-glutamine, L-Tyrosine, L-Arginine, Beta Alanine, Monoammonium Glycyrrhizinate, GABA (Gamma Aminobutyric Acid), L-Tryptophan and L-Carnitine HCl. The label gives no amount for any single ingredient inside the blend, so you cannot tell how much of each one is in a serving.
The Other Ingredients line reads: water, natural flavors, potassium sorbate, stevia, xylitol and citrus extract.
What does the maker say Cognizil is for?
The label carries the words “Advanced Memory Support” with an asterisk that leads to the FDA disclaimer. The seller’s website says Cognizil “is designed to support cognitive function and mental clarity.” Both are the maker’s own wording. The label also says the product is not intended to diagnose, treat, cure or prevent any disease, and that its statements have not been evaluated by the Food and Drug Administration.
What does the research say about each ingredient?
Each row below names one study and what it covers. Read the scope before you assume a match, because most of these studies test one ingredient on its own, and none of them tests Cognizil.

The NIH Office of Dietary Supplements has fact sheets on chromium and carnitine, which cover the two ingredients listed on the label as single, quantified amounts or named nutrients rather than as studies of memory or focus.
Four of these studies look at thinking directly: ginseng, guarana, eleuthero and L-tyrosine. The eleuthero study’s title reports no benefit in the group it studied. Maca, African mango, astragalus, green tea, gymnema and forskohlii have no study named in this table. For those six, the most useful question for the seller is which study, if any, tests that ingredient for memory or focus, and at what amount.
Who should avoid Cognizil, and what about side effects?
The label says Cognizil is not for anyone under 18, or for pregnant or nursing women. It says people with a known medical condition should consult a physician before using this or any dietary supplement, and not to exceed the recommended dose.
Two of the studies above raise safety questions. The 2001 and 2007 papers identified benzethonium chloride in commercial grapefruit seed extract products, and the 2007 paper also named methyl paraben and triclosan. The grapefruit seed in Cognizil’s blend is listed without any statement about testing for those preservatives, so ask the seller before you order. The 2018 arginine study covers safety of arginine supplements in adults.
Who makes Cognizil?
The label says the product was manufactured in an FDA registered facility. The label also says it is made in the USA with globally sourced ingredients, and it lists a mailing address and a support email.
What else helps memory and brain fog?
Memory changes and brain fog can have many causes, and no single ingredient addresses all of them. The Harvard Health memory topic says: “Proven ways to help protect memory include following a healthy diet, exercising regularly, not smoking, and keeping blood pressure, cholesterol, and blood sugar in check.” The Cleveland Clinic memory tips say that when memory problems start to interfere with daily life, it is time to talk with a healthcare provider. The Memory and Brain Fog guide on this site walks through the options.
What should I check before I order Cognizil?
- Compare the Supplement Facts panel on the bottle you receive with the list above. The label is the reference for amounts.
- Ask the seller for the amount of each blend ingredient, how much caffeine the guarana contributes (the panel does not show a caffeine amount), and whether the grapefruit seed was tested for the preservatives named in the 2001 and 2007 studies.
- Compare the refund terms. The seller’s homepage shows a 180-day guarantee, while independent pages describe a 60-day guarantee. Get the term and its start date confirmed in writing before you order.
- Prices and bundles change. Check today’s price directly with the company.
- Read the Cognizil legit seller contact checklist before you pay.
