Effective Natural Products has always specialized in liquid vitamin supplements. Absorption for system use is the main key and reason we do so. According to the highly respected and referenced Physicians’ Desk Reference (designed to provide physicians with the full legally mandated information applicable to all prescription drugs), only about 10% to 20% of the nutrients in vitamin pills are absorbed by the body. Pills, tablets and capsules are made with many fillers and binding ingredients that can actually inhibit absorption of active nutrients. Liquid vitamins and sprays can be utilized and absorbed up to 98%.
