HelloPharmacist Scorecard of NADH 10 mg by NOW

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: NADH (10 mg per capsule) and Bioenergy Ribose. NADH is a coenzyme that plays a role in energy production in your cells.

Bioenergy Ribose is a five-carbon sugar involved in ATP synthesis, the process your body uses to generate energy. The remaining ingredients are inactive — they're just the capsule material and binders (hypromellose, microcrystalline cellulose, stearic acid, magnesium stearate, silicon dioxide, and beeswax).

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: cellular energy production and neurotransmitter support.
  • We looked for evidence on: Athletic performance, Chronic fatigue syndrome (CFS), Cognitive function, Fibromyalgia, Jet lag, Parkinson disease — and 3 related terms.
  • The strongest evidence on file: Nadh is rated "Possibly Effective" for Chronic fatigue syndrome (CFS) (Natural Medicines).
  • Also on file: Ribose is rated "Possibly Ineffective" for Athletic performance.
  • Also on file: Ribose is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Cognitive function, Fibromyalgia.

For NADH, the evidence is modest: it's rated possibly effective for chronic fatigue syndrome (CFS), but there isn't enough reliable evidence to know whether it helps with Parkinson disease, dementia, or alcohol-related liver disease. For Bioenergy Ribose, the picture is less encouraging — it's rated possibly ineffective for athletic performance and McArdle disease, and the evidence is insufficient to rate it for restless legs syndrome, congestive heart failure, muscle soreness, or recovery from bypass surgery.

In short, neither ingredient has strong evidence backing its use for most conditions.

The evidence, ingredient by ingredient Nadh Ribose

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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both NADH and Bioenergy Ribose are generally well tolerated in the short term, but long-term safety data are limited — we simply don't know what happens if you take them for months or years. Ribose can cause diarrhea, nausea, headache, lightheadedness, and anxiety in some people; lowering the dose has resolved nausea and anxiety in some cases.

It can also lower your blood sugar, even on its own. For pregnancy and breastfeeding, there isn't enough safety information for either ingredient — both should be avoided during pregnancy and while nursing.

Talk with your doctor or pharmacist if you're planning a pregnancy or are breastfeeding.

Side effects, ingredient by ingredient Nadh Ribose

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 2 matched ingredients can interact with medications — Ribose.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

Before taking this product, double-check with your pharmacist if you take insulin or antidiabetes drugs (like metformin, glipizide, glyburide, or pioglitazone) — Bioenergy Ribose can lower blood sugar and increase the risk of hypoglycemia when combined with these medications. The NADH component has no documented interactions with medications in our data.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're looking for an energy support supplement and don't take diabetes medications or insulin. If you do take blood sugar drugs, check with your pharmacist first — the Bioenergy Ribose component could increase your hypoglycemia risk.

Long-term safety isn't well established, so it's a supplement to discuss with your healthcare provider before starting, especially if you're pregnant, breastfeeding, or managing a chronic condition.

Formula

NADH (Reduced Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that is derived from Vitamin B-3, also known as Niacin. NADH is an essential cofactor for hundreds of biochemical reactions, and is used extensively in the production of cellular energy (ATP). NADH also plays a notable role in the synthesis of neurotransmitters in the brain. Although NADH is normally unstable outside of the body, PANMOL NADH uses a patented process to naturally preserve its effectiveness, thereby delivering stable and bioavailable NADH to the body.

NADH 10 mg by NOW: Common Questions

Does NADH 10 mg by NOW interact with any medications?
Yes. Based on its ingredients, NADH 10 mg has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
NADH 10 mg contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant or breastfeeding?
No — there isn't enough safety information for either NADH or Bioenergy Ribose during pregnancy or while breastfeeding. Both should be avoided. Talk with your doctor or pharmacist about what's safe for you if you're planning a pregnancy or nursing.
What side effects should I watch for?
Bioenergy Ribose may cause diarrhea, nausea, headache, lightheadedness, or mild anxiety. Lowering the dose has helped some people. NADH has no reported adverse effects in the data we hold. Both are generally well tolerated short-term, but long-term safety isn't well studied.
Does NADH actually help with fatigue or chronic fatigue syndrome?
The evidence says NADH is possibly effective for chronic fatigue syndrome, which means there's some promise but it's not proven. For other causes of fatigue, we don't have reliable evidence.
Will this help my athletic performance?
Bioenergy Ribose is rated possibly ineffective for athletic performance, so the evidence doesn't support it for that use. The effectiveness of NADH for sports performance isn't established in our data either.
Is this safe to take long-term?
Both ingredients are generally well tolerated short-term, but long-term safety data are limited. We don't know what happens with extended use, so it's a good question to ask your pharmacist or doctor if you're thinking about taking it regularly.
Can this lower my blood sugar?
Yes — Bioenergy Ribose can lower blood sugar on its own, and that effect is stronger at higher doses. If you take insulin or diabetes medications, this is a real concern and you need to check with your pharmacist first.
