Performance Lab Vitamin C Review 2026: Worth the Price?
Read before you buy. — Mostly Legit
-
"Transparent, no hidden doses"
The label lists the exact 250mg dose and states there are no proprietary blends. That's better than many competitors.
-
"Boosts immunity"
For adults eating a normal diet, extra vitamin C shows no reliable immune benefit. It mostly helps the deficient.

"NutriGenesis has enhanced bioavailability"
No published human trial shows this cultured form absorbs better than standard vitamin C. The claim is marketing, not data.
-
"Fair value for a vitamin C supplement"
About $1 per 250mg serving. Wholesale vitamin C costs roughly a penny per dose — a 10-20x markup.
Consumer advice
If you actually eat fruits and vegetables, you almost certainly don't need this. If you want a vitamin C supplement, a $10 bottle of Nature Made C with bioflavonoids does the same job for a fraction of the price. The clean label, vegan certification, and third-party testing are genuine pluses, but they don't justify paying several times more for 250mg of a vitamin that costs pennies. Note the product is currently out of stock. Skip the "soil depletion" and "lab-grown nutrient" marketing — a normal diet plus a cheap supplement covers your vitamin C needs.
Claims vs Evidence
MODERATE0 of 5 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
