Testing & evidence

Testing claimed

Evidence status
Testing claimed
Manufacturer statement
Nutravita’s product page says "Laboratory tested products"; the Ingredients page says ingredients go through "strict testing" and that "the testing is done in-house at the manufacturing site." I did not find any independently verifiable third-party lab report or certification for this specific product, and the only registry result I found was NSF listings for other brands/products, not Nutravita Vitamin D3 Drops.
