Today, about 46 percent of adult Americans take nutritional supplements daily. It is no longer just a fad, but part of a growing trend as more and more people take a proactive approach to their own health care.

   In spite of all researches conducted in this field , there is still no definitive scientific "how-to guide" for this very complex issue, especially since each individual's needs are different.

  While it is always recommended that a person try to obtain as many nutrients as possible through the consumption of a variety of high- nutrient-density foods, this can be unrealistic for many, due to reduced calorie intake; the dislike of certain foods; loss of nutrients in cooking; the variable quality of food supply; lack of knowledge, motivation, or time to plan and prepare balanced meals; and nutrient depletion caused by stress, lifestyle, and certain medications. This is where nutritional supplements can play an important role in filling any nutrient gaps.

  Nutritional supplements carry some potential risks. Prolonged intake of excessive doses of vitamin A, vitamin D, and vitamin B₆, for example, may produce toxic effects. Other vitamins, minerals, and accessory nutrients can also sometimes cause side effects when they interact with medications, or due to health conditions or simply a person's biochemical individuality. However, alternative practitioners may sometimes recommend dosages higher than those currently considered safe by conventional medicine. The scientific literature and numerous clinical trials support these elevated dosages for short periods of time and only under medical supervision. Dr. Berkson, says that many alternative practitioners use extremely elevated levels of vitamin A for several days to a week to act as a natural antibiotic for acute infection.

 

  Nutritional supplements should also never take the place of proper dietary habits or appropriate medical care when warranted. If someone is currently under medical care, is taking any medications, or has a history of specific problems, it is important for him to always consult with a physician before making any changes in diet or lifestyle, including the use of supplements.

  It can take years of personal research and experimentation to put together a good dietary and supplement program. A person should consult a qualified health professional trained in the intricacies of nutritional biochemistry, to help the person assess his personal needs and to help develop an effective dietary and nutritional supplement program tailored to biochemical individuality.

  High-quality nutritional supplements can often be obtained through these professionals, or from a source recommended by them. When making a decision to purchase nutritional supplements without the advice of an expert, do so as an informed consumer. It is worthwhile to read some of the many books and magazines published about good dietary habits and nutritional supplements. Reputable health food stores are a good source of quality supplements and are also usually staffed by people who have a knowledgeable understanding of nutrition and supplementation. Some pharmacies specialize in nutritional and natural remedies as well; there are also several good mail order and direct outlets.

  One should look beyond statistical guidelines in order to gain a greater understanding of the role and proper level of nutrients that will help every individual achieve and maintain a high level of wellness. Through education and involvement, a person can develop an understanding of the proper diet and nutritional needs specifically suited to the body, and should make this knowledge an integral part of living well.

 

  Before taking any nutritional supplement you should ask what scientific data supports its safety and what are the safe intake levels for the nutrients you are considering taking. Jeffrey Bland, Ph.D., of Gig Harbor, Washington and D. Lindsey Berkson, M.A., D.C., of Santa Fe, New Mexico, make the following recommendations:

 

• Nutritional supplements should be taken with meals to promote increased absorption. Fat-soluble vitamins (such as vitamin A, beta-carotene, vitamin E, and the essential fatty acids linoleic and alpha linolenic acid) should be taken with the meal which contains the most fat during the day.
• Amino acid supplements should be taken on an empty stomach at least an hour before or after a meal, and taken with fruit juice to help promote absorption. Whenever taking an increased dosage of an isolated amino acid be sure to supplement with an amino acid blend.
• If you become nauseated when you take tablet supplements, consider taking a liquid form, diluted in a beverage.
• If you become nauseated or ill within an hour after taking nutritional supplements, consider the need for a bowel cleanse or rejuvenation program prior to beginning a course of nutritional supplementation.
• If you are taking high doses, do not take the supplements all at one time, but divide them into smaller doses taken throughout the day.
• Take digestive enzymes with meals to assist digestion. If you are taking pancreatic enzymes for other therapeutic reasons, be sure to take them on an empty stomach between meals.
• Take mineral supplements away from the highest fiber meals of the day as fiber can decrease mineral absorption.
• Whenever taking an increased dosage of an isolated B vitamin, be sure to supplement with a B-complex.
• When taking nutrients be sure to take adequate amounts of liquid to mix with digestive juices and prevent side effects.
