MemoVance Pro Ingredients: The Seven in Each Capsule

The one row on this panel at a nutritionally meaningful figure, and the only one carrying a percentage of a Daily Value rather than a dagger. Seven and a half milligrams of niacin equivalents is roughly what a generous portion of chicken breast or tuna supplies, which is the right way to picture it.

Niacin is a precursor to NAD, the coenzyme every cell uses to turn food into usable energy, and the brain is among the hungriest customers for it. That is the honest reason a B3 row belongs in a formula sold for cognitive function, mental clarity. The vitamin’s louder literature sits in the grams: the HPS2-THRIVE trial gave 25,673 adults two grams a day of the extended-release form, two hundred and sixty-six times this row.

Eighteen milligrams of elemental calcium, printed with a European decimal comma the artwork reproduces exactly. In a formula this size the carbonate is doing structural work inside the capsule as much as nutritional work inside the person.

The useful thing about a figure this small is what it rules out. Calcium carbonate is the classic supplement-timing problem because it binds thyroid hormone in the gut: the JAMA study that established it used 1,200 mg of elemental calcium a day, and the follow-up comparing three calcium salts used 500 mg. At 18 mg this row is between twenty-seven and sixty-seven times smaller than either, so a person on levothyroxine can read it and move on.

Arginine is the direct substrate for nitric oxide synthase, the enzyme that makes nitric oxide, and nitric oxide is what relaxes the lining of a blood vessel. Two hundred milligrams is the joint-largest amount on this label.

The dose literature is unusually clear for an amino acid. A 2022 dose-response meta-analysis in Advances in Nutrition pooled the randomised trials and found blood pressure moved at four grams a day and upward, with nothing detectable below it. A 2026 reassessment using ambulatory monitoring revisited the same question with better measurement.

One study in this neighbourhood looked at thinking rather than circulation: an acute trial of inositol-stabilised arginine silicate reported improved cognitive outcomes in healthy adults at 1.5 g, a different stabilised compound at seven and a half times this row.

Arginine bonded to alpha-ketoglutarate in a two-to-one ratio, which is the form the sports-nutrition shelf standardised on in the 2000s. It exists because the salt was believed to survive first-pass metabolism better than the free base beside it.

Both of the human trials that examined it seriously used twelve grams a day. The eight-week pharmacokinetic and safety study in trained men ran four grams three times daily, and the seven-day blood-flow trial used the same total. Twelve grams is sixty times the 200 mg printed here.

The smaller acute studies are the more interesting comparison, because they failed. Three grams taken acutely did not improve muscular performance, and 3,700 mg per serving changed neither muscle endurance nor blood pressure.

Citrulline is the indirect route to the same chemistry as arginine. Swallowed arginine is largely stripped out by arginase in the gut wall and the liver; citrulline slips past that, reaches the kidney and is converted to arginine there, which is why it raises circulating arginine more reliably than arginine does.

The study everyone in this category leans on is Schwedhelm's 2008 pharmacokinetic work, and it is worth reading closely rather than citing. It tested a ladder of doses and only the top rung, three grams twice a day, lifted the plasma arginine trough. That is sixty times the citrulline salts on this panel added together.

The lowest citrulline dose with a positive human result found anywhere in this search was 800 mg a day paired with 300 mg of trans-resveratrol, which is still eight times this row and carries a second active the capsule does not contain.

The same amino acid attached to malic acid, a Krebs-cycle intermediate. Splitting a citrulline allowance across two salts is a formulation decision rather than a nutritional one, and it is the reason this panel prints four amino rows where a simpler label would print two.

Citrulline malate is the pre-workout ingredient proper. The meta-analysis of its effect on repetitions during strength training covers trials that gave six to eight grams forty to sixty minutes before exercise, and the review of perceived exertion and muscle soreness reports eight grams as the commonest dose across its included studies.

Six grams against one hundred milligrams is a sixtyfold gap, and it is the cleanest illustration on the label of why a printed amount is worth more than a long ingredient list.

Beta-alanine has nothing to do with nitric oxide. It is the rate-limiting building block for carnosine, a dipeptide stored in muscle and, in smaller quantities, in brain tissue. Loading it raises muscle carnosine over weeks, not hours.

The International Society of Sports Nutrition position stand asks for four to six grams a day for at least four weeks before carnosine moves, and notes that the tingling sensation people associate with the ingredient is managed by splitting doses of 1.6 g. One point six grams is forty times this row, so nobody will feel anything from this capsule.

The cognition work is the reason a memory formula carries it at all, and it is mixed. Ostfeld's 2023 study in older adults used 2.4 g a day and reported gains, with a hippocampal imaging follow-up at the same dose; fourteen weeks at 6.4 g a day moved neither BDNF nor Stroop performance.
