Ingredient review
Disodium NADH
INCI: DISODIUM NADH
Disodium NADH is a promising antioxidant that supports skin cell energy, but research is still early and it's less proven than classic antioxidants like vitamin C.
In plain English
Disodium NADH is a form of a molecule your skin cells naturally use to produce energy. Think of it as a tiny battery charger for your cells. In skincare, it's added to help protect skin from damage and support repair, but it's a newer ingredient, so we don't have decades of proof like we do for vitamin C or niacinamide.

Quick decision guide
Useful, but context matters
Disodium NADH is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Disodium NADH.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Disodium NADH is the salt form of NADH (nicotinamide adenine dinucleotide), a coenzyme found in every living cell. It is produced through biotechnology and is more stable in water-based formulas than plain NADH.
How it works
In the skin, NADH helps fuel cellular energy production. When applied topically, it may boost the skin's natural repair processes and act as an antioxidant, neutralizing free radicals that cause premature aging. It also supports the activity of other repair enzymes in the skin.
Pros
Supports skin energy
NADH is a key molecule in cellular energy production, so applying it may help skin cells function better and repair more efficiently.
Antioxidant protection
It can neutralize free radicals, helping to prevent oxidative stress that leads to fine lines and dullness.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are still lacking, so its real-world benefits are not fully proven.
Stability concerns
NADH is sensitive to light and air, so it requires careful formulation to remain effective, which can make products more expensive.
Best for
- People looking for advanced antioxidant support
- Those interested in cellular repair and anti-aging ingredients
Use caution if
- Anyone with known sensitivity to niacin derivatives
- Those on a very tight budget (it's a premium ingredient)
Usage tips
Safety summary
Disodium NADH is considered safe for topical use at typical concentrations. It has low irritation and comedogenic potential. However, due to limited long-term data, those with very sensitive skin should patch test first.
Research notes
Early research suggests NADH can boost cellular energy and act as an antioxidant in skin cells. Small human studies show improvements in skin firmness and brightness, but more robust clinical trials are needed to confirm these effects.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the EU and US; not a drug or medical treatment.
- Common uses
- Anti-aging serums, Brightening treatments, Repair creams
- Environmental note
- Produced via biotechnology, which generally has a lower environmental footprint than extraction from natural sources.
Good to know
- NADH is different from NAD+; NADH is the reduced (active) form.
- It is often used in anti-aging products alongside peptides and growth factors.
