Shore Magic Collagen has superior absorption capabilities (up to 19 times more absorbable) than typical sources of collagen such as porcine and bovine collagen supplements. This is due to the lower weight of the molecules used in our collagen. Shore Magic is third-party tested and certified twice for purity. Shore Magic is also certified hypoallergenic. Shore Magic is the purest collagen on the market today, and we maintain our product as one pure ingredient with no dangerous additives or fillers and no synthetic vitamins or herbs.
