HelloPharmacist Scorecard of Maximum-Strength NADH 20 mg by Swanson Ultra

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 lozenge contains one active ingredient: NADH at 20 mg per dose. NADH is a coenzyme — a helper molecule your cells use to produce energy and support several metabolic processes.

The remaining ingredients are inactive: xylitol (a sweetener), hydroxypropyl cellulose and crospovidone (binders and disintegrants to help the lozenge dissolve), rice extract, natural peppermint flavor, and sodium copper chlorophyllin (a coloring agent).

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: fast-acting energy and mental clarity.
  • We looked for evidence on: Chronic fatigue syndrome (CFS), Jet lag, Athletic performance.
  • The strongest evidence on file: Nadh is rated "Possibly Effective" for Chronic fatigue syndrome (CFS) (Natural Medicines).
  • Also on file: Nadh is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Jet lag.

NADH is possibly effective for chronic fatigue syndrome (CFS) — meaning there's some evidence it may help, but the research isn't conclusive yet. For Parkinson disease, dementia, and alcohol-related liver disease, we don't have enough reliable evidence to say whether it works.

If you're considering it for CFS specifically, talk with your doctor about what the current research shows and whether a trial makes sense for your situation.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

NADH is generally well tolerated in the short term, but we have limited long-term safety and quality data — so we don't know much about taking it for months or years. The safety data advises against using it during pregnancy or breastfeeding because there isn't enough information to know it's safe for you or your baby.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. That said, mention this supplement to your doctor or pharmacist before taking it — they can review your full medication list and medical history to spot anything we might have missed.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

This NADH supplement may be worth considering if you have chronic fatigue syndrome and want to explore options beyond standard care. It's generally well tolerated short-term, but long-term safety hasn't been well studied.

If you're pregnant, breastfeeding, or taking medications for neurological or energy-related conditions, discuss this with your doctor or pharmacist before you start.

Maximum-Strength NADH 20 mg by Swanson Ultra: Common Questions

Does Maximum-Strength NADH 20 mg by Swanson Ultra interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Maximum-Strength NADH 20 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Maximum-Strength NADH 20 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is NADH and what does it do?
NADH is a coenzyme — a molecule your cells naturally make and use to produce energy and carry out other chemical processes. This supplement delivers a concentrated dose in the hope of boosting those cellular functions, particularly energy production.
Does this NADH lozenge actually work?
For chronic fatigue syndrome, there's some evidence it may help — that's why we rate it as possibly effective. For Parkinson disease, dementia, and liver disease, we don't have enough reliable research to say either way. Results vary from person to person.
Can I take this while I'm pregnant?
The safety data advises against it — there isn't enough information to know whether NADH is safe for you or your developing baby. Talk with your doctor or pharmacist about whether this is right for you.
Can I take this while breastfeeding?
The safety data advises against it because we don't have enough information to know whether it's safe for your baby. Check with your doctor or pharmacist before taking it while nursing.
Are there any side effects?
In the short term, NADH is generally well tolerated — we don't have a list of common side effects from the data we hold. Long-term safety information is limited, so watch for any unusual symptoms and report them to your pharmacist or doctor.
What's in the lozenge besides NADH?
The inactive ingredients are xylitol (sweetener), hydroxypropyl cellulose and crospovidone (to help it dissolve), rice extract, natural peppermint flavor, and sodium copper chlorophyllin (for color). None of these are active medicinal ingredients.
