Common ones01
What are the most common memory supplement ingredients?
The most common memory supplement ingredients are B vitamins, plant extracts such as ginkgo and curcumin, and amino acids.
The NCCIH summary found no conclusive evidence that ginkgo slows cognitive decline, limited and inconsistent evidence for curcumin, and no help for thinking from short-term B6, B12 and folic acid in adults 50 and older (NCCIH, Supplements and cognitive function). Direct evidence for natural products is lacking.
Ginkgo is not on the bottle label printed on this site. Cochrane's pooled B-vitamin trials, 879 people, saw no clear difference after 6 to 24 months (Cochrane 2018, Vitamin and mineral supplements and thinking skills). Niacin was not covered.

Which ingredients are in HoneyPezil?
HoneyPezil has seven label lines: niacin, calcium, two arginine lines, two citrulline lines and beta alanine.
Every amount is printed. The amino acid lines add up to 640 mg per capsule as printed. The groups below show how the lines fit together.
Vitamin and mineral
- B3Niacin7.5 mg NE · 47% DV
- CaCalcium (as calcium carbonate)18 mg · 1.5% DV
Amino acids: five lines, three amino acids
- ArL-arginine (base)200 mg · DV not established
- AKL-arginine AKG 2:1 extract200 mg · DV not established
- CiL-citrulline HCl100 mg · DV not established
- CML-citrulline malate100 mg · DV not established
- bABeta-alanine40 mg · DV not established
From the Supplement Facts box, in label order. Every amount is printed; there is no proprietary blend. Other ingredients (hypromellose vegetable capsule, vegetable stearate, silicon dioxide) are not active lines.
The label does not print the niacin form. It also does not say how much of the 200 mg AKG line is arginine or how much of the 100 mg malate line is citrulline, so we say at most 400 mg of arginine ingredients and at most 200 mg of citrulline ingredients.
Studies03
What did studies measure for each HoneyPezil ingredient?
Studies measured mostly blood pressure, exercise and blood levels, and used far more than one capsule holds.
No memory trial was found for the label amounts. The table gives what each source measured, not what a capsule does.
| Ingredient | Label | A studied amount | Measured |
|---|---|---|---|
| Arginine ingredients | At most 400 mg | 4 g or more a day | Blood pressure (Shiraseb 2022, Arginine and blood pressure) |
| Citrulline ingredients | At most 200 mg | Up to 6 g a day | Short safety studies (NIH ODS, Exercise and athletic performance supplements) |
| Beta-alanine | 40 mg | 4 to 6 g a day | Muscle carnosine (Trexler 2015, ISSN position stand: Beta-alanine) |
| Niacin | 7.5 mg NE | RDA 14 to 16 mg NE | Food intake, observational (Morris 2004, Dietary niacin and cognitive decline) |

What do ingredient studies not show about memory supplements?
Ingredient studies do not show that a capsule with a smaller amount does the same thing.
A study of arginine silicate at 1,500 mg was company-funded and used healthy young men (Kalman 2016, Arginine silicate and mental tests). That is a different compound. One small trial in 19 older adults found arginine did not help a thinking test (Beckman 2018, Arginine and executive function in older adults). It was short and small, so it is not proof of harm.
Single studies also do not cover mixtures. Read the dose gap page for the full numbers. Ask a pharmacist before you add any new ingredient to your medicines.
FAQ05
HoneyPezil questions people ask
Which memory supplement ingredient has the most evidence?
None has strong evidence for memory in the sources we read. The NIA recommends no vitamin or supplement for preventing cognitive decline.
Is niacin in HoneyPezil the flushing type?
The label does not say which form of niacin is used. At 7.5 mg NE, flushing is typically reported at much higher nicotinic acid amounts.
Are the HoneyPezil ingredients in a proprietary blend?
No. All seven lines list their own amount, and the five amino acid lines add up to 640 mg as printed.
