However, if a product folds in antioxidant-rich ingredients (like vitamins C and E, turmeric, etc.), the product may be able to get away with a longer shelf life. See, antioxidants protect against oxidation (hence anti and oxidant), which can help buffer a formula from degrading over time. “It’s like a natural preservation system, thanks to the power of antioxidants,” says Ferira. Of course, that’s not the only reason we formulated our beauty & gut collagen+ with these antioxidants—vitamin C is a vital part of the collagen production process, and vitamin E, turmeric, and sulforaphane glucosinolate all help protect the skin from photoaging—but they do extend the shelf life some.* Consider it a bonus perk.
As we mentioned above, people who adopt a regular collagen routine won’t likely run into any expiration issues (in fact, they’ll probably run through product after product rather quickly). However, if you do notice some sensorial changes with the powder, it might be time to toss it. “That could involve clumping of powder or very noticeable changes in color, smell, or taste,” notes Ferira.
