Vitamins and Dietary Supplements

Vitamins are essential to life. They contribute to good health by regulating the metabolism and assisting the biochemical processes that release energy from digested food. They are considered micronutrients because the body needs them in relatively small amounts compared with nutrients such as carbohydrates, proteins, fats, and water.

Enzymes are essential chemicals that are the foundation of human bodily functions. They are catalysts (activators) in the chemical reactions that are continually taking place within the body. As coenzymes, vitamins work with enzymes, thereby allowing all the activities that occur within the body to be carried out as they should. Whole, fresh raw foods are a good source of enzymes.

Of the major vitamins, some are soluble in water and others in oil. Water-soluble vitamins must be taken into the body daily, as they cannot be stored and are excreted within four hours to one day. These include vitamin C and the B-complex vitamins. Oil-soluble vitamins can be stored for longer periods of time in the body's fatty tissue and the liver. These include vitamins A, D, E, and K. Both types of vitamin are needed by the body for proper functioning.

RDA Vs. RDI Vs. ODI

Recommended Dietary Allowances (RDAs) were instituted more than forty years ago by the National Academy of Sciences U.S. Food and Nutrition Board as a standard for the daily amounts of vitamins needed by a healthy person. These RDAs were the basis for the U.S. Recommended Daily Allowances (U.S. RDAs) adopted by the Food and Drug Administration (FDA). The provisions of the Nutrition Labeling and Education Act and the Dietary Supplement Act of 1992 required a change in food product labeling to use a new reference term, Daily Value (DV), which began to appear on FDA-regulated product labels in 1994. DVs are made up of two sets of references: Daily Reference Values (DRVs) and Reference Daily Intakes (RDIs).

DRVs are a set of dietary references that apply to fat, saturated fat, cholesterol, carbohydrate, protein, fiber, sodium, and potassium. RDIs are a set of dietary references based on the Recommended Dietary Allowances for essential vitamins and minerals and, in selected groups, protein. The term RDI replaces U.S. RDA.

Unfortunately, the amounts of these nutrients defined by the Recommended Dietary Allowances give us only the

bare minimum required to ward off vitamin deficiency diseases such as beriberi, rickets, scurvy, and night blindness. What they do not account for are the amounts needed to maintain maximum health, rather than borderline health.

Scientific studies have shown that taking dosages of vitamins above the RDIs helps our bodies work better. The RDIs therefore are not very useful for determining what our intake of different vitamins should be. We prefer to speak in terms of optimum daily intakes (ODIs) the amounts of nutrients needed for vibrant good health. This entails consuming larger amounts of vitamins than the RDIs. The nutrient doses recommended on page 9 are ODIs. By providing our bodies with an optimum daily amount of necessary vitamins, we can enhance our health. The dosages outlined in this book will enable you to design a vitamin program that is custom-tailored for the individual.

Balance and Synergy

Having the proper balance of vitamins and minerals is very important. Scientific research has proved that excesses of isolated vitamins or minerals can produce the same symptoms as deficiencies of vitamins or minerals.

For example, high doses of isolated B vitamins have been shown to cause the depletion of other B vitamins. Similarly, if zinc is taken in excess, symptoms of zinc deficiency can result. Studies have shown that an intake of up to 100 milligrams of zinc daily enhances immune function, but an amount in excess of 100 milligrams daily may actually harm immune function.

Synergy is a phenomenon whereby two or more vitamins combine to create a stronger vitamin function than the sum of their individual effects would suggest. For example, in order for bioflavonoid to work properly (they prevent bruising and bleeding gums), they must be taken along with vitamin C. Recent studies show that bioflavonoid also may be a big factor in preventing cancer and many other diseases.

In addition, certain substances can block the absorption and effects of vitamins. For example, the absorption of vitamin C is greatly reduced by antibiotic drugs, so a person taking antibiotics requires a higher than normal intake of this vitamin.

Synthetic Versus Natural

Ideally, all of us would get all of the nutrients we need for optimal health from fresh, healthful foods. In reality, however, this is often difficult, if not impossible. In our chemically polluted and stress-filled world, our nutritional requirements have been increasing, but the number of calories we require has been decreasing, as our general level of physical activity has declined. This means we are faced with needing somehow to get more nutrients from less food. At the same time, many of our foods are depleted of certain nutrients. Modern farming practices have resulted in soils that are lacking in selenium and other nutrients.

Harvesting and shipping practices are dictated not by nutritional considerations but by marketing demands. Add to this extensive processing, improper storage, and other factors, and it is little wonder that many of the foods that reach our tables cannot meet our nutritional needs. Getting even the RDIs of vitamins from today's diet has become quite hard to do. This means that for optimum health, it is necessary to take nutrients in supplement form.

Vitamin supplements can be divided into two groups synthetic and natural. Synthetic vitamins are produced in laboratories from isolated chemicals that mirror their counterparts found in nature. Natural vitamins are derived from food sources. Although there are no major chemical differences between a vitamin found in food and one created in a laboratory, synthetic supplements contain the isolated vitamins only, while natural supplements may contain other nutrients not yet discovered. This is because these vitamins are in their natural state. If you are deficient in a particular nutrient, the chemical source will work, but you will not get the benefits of the vitamin as found in whole foods. Supplements that are not labeled natural also may include coal tars, artificial coloring, preservatives, sugars, and starch, as well as other additives. You should beware of such harmful elements.

However, you should also note that a bottle of "natural" vitamins might contain vitamins that have not been extracted from a natural food source. It is necessary to read labels carefully to make sure the products you buy contain nutrients from food sources, with none of the artificial additives mentioned above.

Studies have shown that protein-bonded vitamins, as found in natural whole food supplements, are absorbed, utilized, and retained in the tissues better than supplements that are not protein-bonded. Chemical-derived vitamins are not protein-bonded. Vitamins and minerals in food are bonded to proteins, lipids, carbohydrates, and bioflavonoid.

Dr. Abram Hoffer, one of the "founding fathers" of orthomolecular medicine (a school of medicine that emphasizes the role of nutrition in health), explains:

Components [of food] do not exist free in nature; nature does not lay down pure protein, pure fat, or pure carbohydrates. Their molecules are interlaced in very complex three-dimensional structures, which even now have not been fully described. Intermingled are the essential nutrients such as vitamins and minerals, again not free, but combined in complex molecules.

Using a natural form of vitamins and minerals in nutritional supplements is the objective of the protein-bonding process. Taking supplements with meals helps to assure a supply of other nutrients needed for better assimilation as well.
