Dr. Ray Strand – Supplementation: Recommended Daily Value (RDA)


Supplementation: Recommended Daily Value (RDA)

I have been specializing in nutritional medicine for more than 17 years. I have also extensively researched medical literature for the same amount of time to develop a definitive understanding of the health benefits my patients could receive by consuming high-quality nutritional supplements. Many of my patients voice a common concern about safety in taking the amount of supplementation I recommend. The medical community has also taken an active role in proclaiming to individuals that nutritional supplements can actually be dangerous to your health. Safety is an important issue, which is why I have dedicated entire chapters to the subject of the safety of nutritional supplements within all five of my international bestselling books. And I’m ready to share with you here as well what I have learned about the safety of supplementation during the past couple of decades.

RDA versus Optimal or Advanced Levels

One of the first things I had to deal with as a physician in medical school was the established bottom line that all you need is RDA (Recommended Daily Allowance) levels of nutritional supplementation. An individual can consume 100% of RDA levels by eating a very healthy diet. This is why most physicians say that you do not need to take nutritional supplements, but instead, just eat a healthy diet. In fact, this is what I told my own patients for the first 23 years of my practice. However, when I began researching how the RDA guidelines were developed, I changed my mind. RDA’s were developed in the late 1930’s and early 1940’s to establish the minimal amount of nutrition needed to avoid acute deficiency diseases like pellagra, scurvy, and rickets. In the early 1950’s, this definition was expanded to include the amount of nutrition for normal growth and development. However, when I began studying medical literature in regard to the health benefits of consuming nutritional supplements within my patients who were suffering from chronic degenerative diseases, I quickly realized that RDA’s had absolutely no health benefits for people suffering from these types of diseases. In fact, it took the consumption of nutritional supplements at much greater levels to have any chance of having a positive response.

The RDA of Vitamin E, for example, is considered 30 IU per day. However, medical literature has not documented any health benefit until a daily level of at least 100 IU is reached. Health benefits have been shown to increase along with the level of Vitamin E intake, maximizing at 400 IU. And further studies have been done with participants consuming over 3,000 IU of Vitamin E, also without harmful side effects. Therefore, most physicians who specialize in nutritional medicine feel that the optimal or advanced level of vitamin E should be around 300-400 IU. Try to go out and eat 400 IU of Vitamin E each day. You would need to eat 33 heads of spinach or 27 pounds of butter or 5 pounds of wheat germ each and every day.

A second example is Vitamin C, which has an RDA of 60 mg daily. However, health benefits have not been documented in medical literature when it comes to diseases like heart disease, cancer, diabetes, and macular degeneration until a daily level of at least 1,000 to 2,000 mg of Vitamin C is reached. In fact, there have been several studies that have given more than 10,000 mg of Vitamin C to their study participants without any adverse effects. Most specialists in nutritional medicine believe that you should be supplementing with at least 1000 to 1200 mg of Vitamin C. In order to consume that amount of Vitamin C in your diet, you would need to eat 18 large oranges or 80 avocados daily.

Government Requires Labels to show % DV based on RDA Levels

The government requires nutritional companies to label their ingredients as % of Daily Values, which are based on RDA levels. When nutritional companies provide data for optimal or advanced levels of nutritional supplements, many are going to be listed as containing a range between 500 to even 3,000 percent of Daily Values. Even though some in the medical community will claim that these are unsafe levels, clinical studies have shown that these levels are well within the safe range. Companies that provide the cellular nutrition I recommend are able to put all of these essential nutrients in convenient mineral and vitamin capsule that allow these nutrients to work together in a synergistic and safe fashion. However, it is easy for someone in the medical community to claim that these are unsafe or dangerous levels because the percent of daily values are so high.

Recommended Daily Allowance levels have nothing to do with chronic degenerative diseases that you want to avoid and offer very little, if any, health benefits. I recommend that all of my patients take the Ariix Optimals. Ariix Optimals contain the optimal or advanced levels of nutritional supplementation that I recommend for all of my patients, which are not only safe, but also in the amount needed to provide significant health benefits. There is a good reason why I titled my book, What Your Doctor Doesn’t Know about Nutritional Medicine. It strongly supports the use of optimal levels of supplementation found in the Antioxidant and Mineral Capsules that make up the Ariix Optimals, and takes you in-depth to detail why it is safe to take these advanced levels of supplementation.
