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.
What’s inside
Full disclosure
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
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
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
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.
