Transporting and storing the materials in a temperature controlled environment is pertinent to insure the longevity of the items. Once the finished products reach the warehouse, rotation and inventory control is the key to maintaining fresh supplements. Just like food and drugs, vitamins age until they have lost their entire potency. Many people take vitamins all their life and wonder why they have medical problems. Medical problems can be magnified by improperly made, irresponsible stored or poor quality raw materials.
Vitamins are a science just like drugs and all other product producing industries.
Unfortunately, there will always be companies who prefer the bottom line in place of your health and quality products. The conversion of food and vitamins are more difficult and the breakdown can be challenging. Absorption into our cells is minimized often resulting in malnutrition. The proper cofactors must be included in a formulation in order to get nutritional benefits. Ratio balancing of the individual ingredients is another fact not to be ignored.
