Primoris is a true one-a-day multi-vitamin that utilizes a patented process called OST, or omega suspension technology, meaning that the vitamin and minerals in our capsules are suspended in omega acids. This allows for a much greater absorption rate and also provides a great sources of essential fatty acids. All of our vitamins and minerals in Primoris are chosen for their bioavailability. Unlike other multi-vitamins, which primarily give you expensive urine, Primoris is absorbed by the body and used for vital functions.
