Niacin flush: could 7.5 mg NE in MemoHoney cause one?
Niacin flush is a warm, red, tingling skin reaction that nicotinic acid can cause at about 30 to 50 mg. MemoHoney prints niacin at 7.5 mg NE, 47% of the Daily Value, but the label does not name the form. The amount is well under the flush range, though the form stays unknown.

What is a niacin flush?
A niacin flush is a warm, red, sometimes itchy or tingling patch of skin, usually on the face and chest, that nicotinic acid can cause at about 30 to 50 mg or more (NIH ODS, Niacin).
It looks alarming but is a known reaction of that one form of vitamin B3. Nicotinamide, the other common form, does not cause it. The upper limit for supplemental niacin in healthy adults is 35 mg a day, and doses of 1,000 mg and up can harm the liver.
So the form matters as much as the number. That is the catch with this label.
How much niacin is in MemoHoney compared with the flush range?
One MemoHoney capsule prints niacin at 7.5 mg NE (47% of the Daily Value), which is about a quarter of the 30 mg where flushing typically begins (MemoHoney label).
"NE" means niacin equivalents. The panel does not say whether the niacin is nicotinic acid, nicotinamide or a mix, so we cannot say which form it is. The label directs one capsule a day, so the daily niacin from the capsule is the same 7.5 mg NE.
| Measure | Amount | Source |
|---|---|---|
| One MemoHoney capsule | 7.5 mg NE | Label |
| Daily Value | 16 mg NE | NIH |
| Flushing from nicotinic acid | About 30 to 50 mg or more | NIH |
| Upper limit, supplements | 35 mg a day | NIH |
| Liver harm reported | 1,000 mg a day and up | NIH |
A flush looks unlikely from this row alone, but skin reacts differently from person to person.
Does niacin help memory, as the marketing lines suggest?
No study we found shows that a niacin capsule helps memory in people who are not deficient.
One large observational study linked more niacin from food with slower decline in older adults, but food habits travel with many other habits (Morris 2004, dietary niacin cohort). Severe deficiency, called pellagra, does cause dementia-like symptoms, yet that says nothing about adding niacin when your intake is normal (Hegyi 2004, pellagra review).
These are the lines a niacin row tends to sit beside, set against what the sources say.
“Boosts nitric oxide”
Arginine and citrulline are building blocks for nitric oxide, but one blood-flow study gave arginine by vein at a very high dose, and no study tested a 200 mg capsule. (Reutens 1997, arginine cerebral flow) (Toda 2009, NO and brain blood flow)
“Improves memory and focus”
No study we found tested these label amounts on memory. One small pilot used 6.4 g of arginine a day; the capsule holds 40 to 200 mg of each ingredient. (Teotia 2026, oral arginine pilot) (NIA, Cognitive health and older adults)
“Supports brain health”
NIA says no supplement is recommended for preventing memory decline, and an expert panel could not endorse any brain-health ingredient. (NIA, Cognitive health and older adults) (GCBH 2019, supplements and brain)
“Reviews prove it works”
Reviews are not evidence of an effect, and fake or bought reviews are banned by an FTC rule. (FTC fake reviews rule) (FTC health products guidance)

See the priceWhat should you do if your skin flushes after a capsule?
If your skin turns warm and red after a capsule, sit down, drink water and let it pass, which usually takes under an hour; stop the capsules and ask a clinician if it repeats.
Hives, swelling of the face or throat, or trouble breathing is not a flush. Treat that as an emergency. Dizziness on standing can point to low blood pressure instead. See the side effects list and the Supplement Facts panel.
Keep taking prescribed medicine exactly as directed. Chest pain, fainting or trouble breathing means call 911. Ask your doctor or pharmacist first if you take nitrates, sildenafil-type medicines, blood pressure medicines or blood thinners, or have had a heart attack, because the arginine rows can interact with them.

FAQ
MemoHoney questions people ask
Is a niacin flush dangerous?
A flush is usually harmless and fades in under an hour, but it can be uncomfortable. Hives, throat swelling or trouble breathing are different and need emergency care. At very high doses, 1,000 mg a day and up, niacin can harm the liver, which is a separate issue.
Does nicotinamide cause flushing?
No. Nicotinamide, the other common form of vitamin B3, does not typically cause the flush that nicotinic acid does. The MemoHoney label does not say which form its 7.5 mg NE of niacin uses, so check with the seller if the form matters to you.
What does mg NE mean on a label?
NE stands for niacin equivalents, a unit that counts niacin from different sources on one scale. The Daily Value is 16 mg NE, so 7.5 mg NE is about 47%. The unit does not tell you whether the niacin is nicotinic acid or nicotinamide.
Can you take niacin with food to avoid flushing?
We found no source that tests this for the MemoHoney capsule, so we cannot say. The label directs one capsule with 8 oz of water, best 20 to 30 minutes before a meal. Follow the label and ask a pharmacist if flushing bothers you.
