The first question you may ask is, “What’s bioavailability?” Bioavailability is the portion of a given active ingredient that is capable of being absorbed through your intestinal membranes into your bloodstream and made available for use by your organs. The amount of each vitamin which is made bioavailable varies from as low as 20% to as high as 98%. Hybrid Nutraceuticals, makers of MiracleMulti™ Multivitamins, would like to discuss what affects the amount of nutrition that your body can absorb.
Enzymes - Some enzymes stimulate vitamin absorption while others inhibit it. When you eat, the absorption of vitamins is usually enhanced by increased secretion of enzymes and bile acid. Some foods contain compounds which inhibit the utilization of vitamins by way of reducing solubility or the amount released. Some raw fruits and vegetables can actually interfere with vitamin absorption. Enzymes that destroy or inactivate thiamine (vitamin B-1), are present in fish, shellfish, and other foods.
Transformation - Certain vitamins are not present in food in a manner that your body can use. For example, riboflavin (vitamin B-2) is present in milk and eggs, but is bound to a carrier protein. The combined compound is known as riboflavin phosphate. In order for the organism to extract the necessary riboflavin from it, this compound must be converted in the intestines with the help of phosphatase enzymes. This conversion process, however, may be hindered by medications, so in some cases taking a vitamin supplement where the nutrient is present in its pure form may be the only way to prevent riboflavin deficiency.
Poor health, toxicity and aging may reduce vitamin absorption - The body has many complex nutrient absorption pathways, and many of these are fragile and easily affected by illness or lifestyle, leading to a cascade of other symptoms. In addition, elderly people have greater requirements for many vitamins, because the ability of their organism to convert and absorb vitamins may be impaired.
Lack of dietary fat - Vitamins can be water soluble or fat soluble. Vitamin D is an example of a fat-soluble nutrient. It is stored in fatty tissue and is released as the tissue is broken down by the body. In addition, fat must be present in your intestines for vitamin D to be properly absorbed. If your diet does not include healthy fatty acids, your ability to absorb vitamin D may be reduced.
