HelloPharmacist Scorecard of NMN, 900 mg by Neurogan Health

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: nicotinamide riboside, a compound related to vitamin B3 that plays a role in cellular energy production. The capsule itself is made from vegetable cellulose.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Nicotinamide Riboside's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: cellular energy and repair for longevity.
  • We looked for evidence on: Athletic performance, Physical performance, Heart failure, Diabetes, Nonalcoholic fatty liver disease (NAFLD), Obesity — and 4 related terms.
  • The closest evidence on file: Nicotinamide Riboside is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Nicotinamide Riboside is rated "Insufficient Reliable Evidence To Rate" for Alzheimer disease, Athletic performance, Nonalcoholic fatty liver disease (NAFLD), Heart failure, and more.

The evidence for nicotinamide riboside is not yet established in our data. We hold insufficient reliable evidence to rate whether it works for age-related macular degeneration (eye health), Alzheimer disease, athletic performance, nonalcoholic fatty liver disease, or heart failure.

That doesn't mean it doesn't work — it means the research so far hasn't been strong enough for us to say one way or the other.

The evidence, ingredient by ingredient Nicotinamide Riboside

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Nicotinamide riboside appears well tolerated in short-term studies, but long-term safety hasn't been fully studied. The most common side effects are bloating, muscle pain, nausea, itching, sweating, and temporary changes in bowel habits.

A small number of trial participants reported mild nausea, bloating, or changes in stools; in one trial, a single person reported leg cramps, and some reported mild muscle soreness. Other gastrointestinal effects like stomach discomfort, diarrhea, and indigestion have been reported with a combination product that also contained another ingredient, so it's unclear whether nicotinamide riboside alone was responsible.

During pregnancy and breastfeeding, the safety data isn't clear enough to know whether this supplement is safe, so the facts advise against use in both situations. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking it.

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Nicotinamide Riboside.
  • The most serious interaction on file is rated Minor.
  • For scale: 172 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take antihypertensive drugs (blood pressure medications), check your specific medications with the tool on this page before starting. The minor risk is that your blood pressure could drop too far when combined.

One small clinical study suggests that nicotinamide riboside can modestly reduce blood pressure in hypertensive patients. However, other clinical research did not find a reduction in blood pressure when compared with control.
