Features

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.

HIGHEST POTENCY: While most B12 supplements contain 1000mcg to 3000mcg per serving, we give you the same number of servings per bottle at 5000mcg, or you can double your servings by taking just 2500mcg - so you get more for your money.

Features

OPTIMAL FORM OF VITAMIN A: Retinyl palmitate is a retinoid (like retinol), meaning it’s bioavailable (easily absorbed into the body) unlike poorly-absorbed beta-carotene.

CLEAR, BEAUTIFUL SKIN: Natural acne treatment, helps reduce scarring as well as follicular hyperkeratosis. It’s an antioxidant for a healthy glow and stimulates collagen production. Retinyl palmitate is found naturally in skin and is a healthy alternative to harsh acne treatments.

MAXIMUM ABSORPTION - Same bioactive form of Vitamin D as Sunshine plus Vitamin K 2 which moves calcium to bones and teeth (and improves absorption!) and away from arteries and brain.

HIGH POTENCY - With 5,000 IU of D3 and 100 mcg of K2 per half dropper liquid serving to quickly build up vitamin D levels and support your bone health and immune system.

NO HARMFUL FILLERS - Our ultra clean formula has no preservatives or unnecessary additives! It's vegetarian, keto-friendly, non-GMO, gluten-free, and tested for purity & potency.
