HelloPharmacist Scorecard of Tru Niagen Pro 300 by ChromaDex

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.

Tru Niagen Pro 300 contains one active ingredient: nicotinamide riboside (branded as Niagen). This is a form of vitamin B3 that your cells use to produce energy and support various metabolic processes.

The capsule also contains inactive ingredients—microcrystalline cellulose (a binder), hypromellose (a capsule material), and vegetable magnesium stearate (a flow agent)—which help deliver the active ingredient.

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: supports mitochondrial health and cellular energy.
  • 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 Athletic performance (Natural Medicines).
  • Also on file: Nicotinamide Riboside is rated "Insufficient Reliable Evidence To Rate" for Nonalcoholic fatty liver disease (NAFLD), Heart failure, Diabetes, Obesity, and more.

The evidence for nicotinamide riboside in the conditions tested—age-related vision loss (macular degeneration), Alzheimer disease, athletic performance, fatty liver disease (nonalcoholic), and heart failure—is currently insufficient. This means the data we hold doesn't establish whether it works for these purposes.

If you're considering this product for a specific health goal, talk with your pharmacist or doctor about what the current research actually supports.

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 to be generally well tolerated in short-term studies, though long-term safety isn't fully established. The most common side effects reported in trials are bloating, muscle pain, nausea, itching, sweating, and temporary changes in bowel movements.

A small number of trial participants experienced leg cramps or mild muscle soreness. The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know it's safe in those situations; talk with your doctor or pharmacist before taking this if you're pregnant, trying to become pregnant, or breastfeeding.

Side effects, ingredient by ingredient Nicotinamide Riboside

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.

Double-check any antihypertensive drugs (blood pressure medications) you're taking with your pharmacist or the interaction tool on this page before starting. Nicotinamide riboside may theoretically add to their blood pressure-lowering effect and increase the risk of excessively low blood pressure.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

Tru Niagen Pro 300 is a single-ingredient nicotinamide riboside product that's generally well tolerated in short term but whose long-term effects remain unclear. If you take blood pressure medication, check it with your pharmacist before starting.

The evidence for the conditions this ingredient is marketed for isn't yet established, so be clear about your actual health goal before taking it.

Antihypertensive Drugs

Theoretically, nicotinamide riboside may have additive effects with antihypertensive drugs, potentially increasing the risk for hypotension.
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.
