Formula
CogniMary Ingredients: Every Item on the Label, Explained
CogniMary lists fifteen active ingredients. Four carry printed amounts: folate 600 mcg DFE, vitamin B12 240 mcg, magnesium 250 mg as oxide and chromium 120 mcg. The other eleven share one 635 mg proprietary blend with no individual breakdown, so their doses cannot be checked by anyone outside the factory.

Declared amounts
The four nutrients printed with numbers
These are the only four ingredients in the formula whose amount you can check against a published reference. Read them first.
| Nutrient | Per 2 capsules | % Daily Value |
|---|---|---|
| Folate (as 320mcg folic acid) | 600 mcg DFE | 150% |
| Vitamin B12 (as cyanocobalamin) | 240 mcg | 10,000% |
| Magnesium (as magnesium oxide) | 250 mg | 60% |
| Chromium (as chromium picolinate) | 120 mcg | 343% |
Folate, as 320 mcg folic acid
600 mcg DFE (150% DV)
Folate is a B vitamin your body uses in one-carbon metabolism, the chemistry behind DNA synthesis and behind keeping homocysteine in a normal range. The adult RDA is 400 mcg DFE, so 600 mcg DFE is a top-up rather than a megadose. Note the form: this is folic acid, the synthetic version, not methylfolate. Folic acid is well absorbed and is what most fortified food uses. The one number worth knowing is the upper limit, which NIH sets at 1,000 mcg of folic acid a day from supplements and fortified food. This label contributes 320 mcg of that, which leaves room but not unlimited room if you also take a multivitamin.
Vitamin B12, as cyanocobalamin
240 mcg (10,000% DV)
The adult RDA for B12 is 2.4 mcg. This label carries a hundred times that. There is no established upper limit for B12 because the body has low capacity to store or misuse it, so the dose is not a safety problem. It is a value problem. Absorption through the active transport route saturates at a few micrograms per dose, and the rest crosses by passive diffusion at roughly one percent. The honest framing is that 240 mcg guarantees you absorb enough even with poor stomach acid or metformin use, and that everything past that is excreted. The form is cyanocobalamin, the cheapest and most stable version. It works for almost everyone and converts fine in the body.
Magnesium, as magnesium oxide
250 mg (60% DV)
Magnesium is involved in hundreds of enzyme reactions including nerve signalling and energy production, and most US adults come up short of the 310 to 420 mg RDA. The amount here is sensible. The form is where this formula loses points. NIH states plainly that magnesium in the aspartate, citrate, lactate and chloride forms is absorbed more completely and is more bioavailable than magnesium oxide. Magnesium oxide is dense, which is why it is used when capsule space is tight, and it is the usual reason a supplement like this causes loose stools in the first week. If a well-absorbed magnesium is the reason you are buying, this is not the bottle to buy.
Chromium, as chromium picolinate
120 mcg (343% DV)
The Adequate Intake for chromium is 20 to 35 mcg depending on age and sex, so this is three to six times that. No upper limit has been set. The reason chromium appears in a brain formula is its association with glucose handling, on the theory that steadier blood sugar means steadier attention. The evidence is thin and the FDA says so: it permits only a qualified claim, and concludes that the relationship between chromium picolinate and insulin resistance or type 2 diabetes is highly uncertain. The American Diabetes Association does not recommend routine chromium supplements. Treat this ingredient as neutral.
The blend
Inside the WMG-NVT Exclusive Blend: 635 mg, eleven items
Everything below shares a single 635 mg total. The label gives the order they are listed in and two standardizations. It does not give individual amounts, and this site will not estimate them.
Bacopa monnieri, whole plant extract, not less than 20% bacosides
The most interesting name on the label. Bacopa has the strongest human evidence of any botanical here for memory specifically, and trials generally run about 300 mg a day of a standardized extract for 8 to 12 weeks before anything shows. The 20% bacosides standardization tells you the grade is real. What it does not tell you is the dose, and 300 mg alone would be nearly half the entire 635 mg blend.
Ginkgo biloba, leaf extract
The best-studied and most sobering ingredient in the formula. NIH's complementary health centre states that ginkgo has not been shown to prevent or slow dementia, and that any benefit for existing dementia symptoms is modest, inconsistent and seen at relatively high doses. Trials typically use 120 to 240 mg a day. Ginkgo also carries the formula's most important interaction: it may raise bleeding risk in people on anticoagulants such as warfarin.
GPC Choline, alpha-Glycerophosphorylcholine
A choline source that crosses into the brain readily and feeds acetylcholine production, which is the neurotransmitter most tied to memory formation. Studied at roughly 400 to 1,200 mg a day. At the low end of that range it would consume nearly two thirds of this blend on its own, which tells you it is almost certainly present well below a studied dose.
L-Theanine
An amino acid from tea leaves associated with calm alertness rather than stimulation. Common study doses are 100 to 200 mg, often paired with caffeine. There is no caffeine in this formula. L-theanine is one of the better-tolerated ingredients on the label and one of the least likely to cause anything unwanted.
Green Tea leaf extract, not less than 50% EGCG
Included for EGCG, the catechin behind most green tea research. The standardization is genuinely useful information. So is the caution: NIH's complementary health centre notes that liver injury, while uncommon, has been reported with green tea products, particularly extracts in capsule form, and that people carrying the HLA-B*35:01 gene variant appear especially susceptible. That variant is carried by roughly 5 to 15 percent of Americans.
Alpha Lipoic Acid (ALA)
A compound that works as an antioxidant in both water-soluble and fat-soluble environments, which is unusual and is why it turns up in nerve and metabolic formulas. Typical study doses run 300 to 600 mg a day, which again is most or all of this blend.
Berberine HCl
Best known for glucose and lipid metabolism rather than cognition. Effective study doses are usually around 500 mg taken two or three times a day. At any amount that could fit inside this blend, berberine is present at a fraction of that. It is worth knowing about anyway because it can interact with diabetes medicine and with several drugs processed by the liver.
Cinnamon, Cinnamomum spp. bark extract
Included for blood sugar support. The label says Cinnamomum spp. rather than naming the species, which matters: cassia cinnamon contains coumarin, which is hepatotoxic in quantity, while Ceylon cinnamon contains very little. Since the amount is inside the blend and the species is not named, neither the dose nor the coumarin exposure can be worked out.
Bilberry, Vaccinium cyanococcus fruit extract
A relative of the blueberry, rich in anthocyanins, traditionally associated with eye health and microcirculation. The research in people is limited and mostly short. Its presence here pairs logically with the lutein and zeaxanthin.
Lutein, marigold flower extract
A carotenoid that concentrates in the macula of the eye and also in brain tissue, where higher levels have been associated with better processing speed in observational work. Supplement trials commonly use 10 to 20 mg a day.
Zeaxanthin, marigold flower extract
Lutein's partner carotenoid, usually dosed alongside it at a roughly 5 to 1 ratio, so around 2 to 4 mg. Together the pair is the most eye-focused part of this formula and the part least connected to its front-panel memory claim.
What the order of the list does and does not tell you
US labelling requires ingredients inside a blend to be listed in descending order by weight. So cinnamon is the largest single item in this blend and zeaxanthin is the smallest. That is real information and it is worth having.
What it cannot tell you is the gap between them. Cinnamon could be 400 mg of the 635, or 80 mg. Both are consistent with the printed label. This is the single biggest limitation of the product and the reason this site scores label transparency at 5 out of 10.
Non-actives
Other ingredients, and what each one is doing
| Ingredient | Why it is there |
|---|---|
| BSE-free gelatin | The capsule shell itself. Sourced to exclude BSE risk. It is animal-derived, so these capsules are not vegetarian or vegan. |
| Rice flour | A bulking agent that fills the gap between the actives and the capsule volume so every capsule weighs the same. |
| Silicon dioxide | An anti-caking flow agent that stops powder bridging in the filling machine. Present in trace amounts. |
| Magnesium stearate | A lubricant that keeps powder from sticking to the tooling. It adds a negligible amount of magnesium on top of the 250 mg declared. |

Questions
CogniMary Ingredients — common questions
Does CogniMary contain caffeine?
No. There is no caffeine on the label. The green tea extract is standardized to EGCG, which is a catechin, not a stimulant, and extracts of this type are usually decaffeinated.
Is CogniMary vegetarian or vegan?
No. The capsule shell is BSE-free gelatin, which is animal-derived. There is no vegetarian version listed.
Does it contain gluten, soy or dairy?
not published. The label does not carry an allergen statement beyond the ingredient list. Nothing in the list is a common allergen, but no free-from claim is made.
Which magnesium is in CogniMary?
Magnesium oxide, 250 mg. NIH states that citrate, lactate, chloride and aspartate forms are absorbed more completely than oxide.
How much bacopa is in each serving?
not published. Bacopa sits inside the 635 mg blend. We will not estimate it.
Is the folate methylfolate?
No. It is folic acid, 320 mcg, declared as 600 mcg DFE. Folic acid is the synthetic form used in most fortified food and is well absorbed by most people.
