SKIN SUPPORT: a meta-analysis of 19 studies showed hydrolyzed collagen noticeably improved skin hydration, had a 35% reduction in wrinkles, and a 40% increase in skin elasticity when consumed for 90 days. It supports repair of skin collagen and elastin fibers, which weaken as we age.
NAILS AND HAIR: collagen improves strength and hydration of dry, brittle nails, and biotin supplementation has been shown to improve nail and hair growth.
SUPERIOR ABSORPTION: marine collagen is absorbed more efficiently than other sources of collagen due to the smaller particle size. Marine collagen is especially rich in glycine and proline, which have been shown to help skin retain moisture and contribute to a supple look and feel.
JOINTS: collagen supplementation has been shown to reduce joint pain by 43% and increase joint mobiity by 39%.
WHY NOT NATURAL QUALITY: no preservatives (like potassium sorbate), no sugar, and no common allergens (besides fish). Our marine collagen is a natural byproduct of the fishing industry and is 100% wild-caught - a sustainble alternative to pork and beef-derived collagen.
