Rainbow Light responds to Archives of Internal Medicine study

Rainbow Light says that assertion that supplement use increases mortality risk is not substantiated.

On October 10th the Archives of Internal Medicine published a study entitled, “Dietary Supplements and Mortality Rate in Older Women.” This study used survey data from 39,000 women, with the mean age of 61.6 years, from the Iowa Women’s Health Study, to assess the use of vitamin and mineral supplements in relation to total mortality. The researchers found that women taking multivitamins don’t live longer than those who get their nutrients from food alone, and that they appear to have a slightly higher death rate. The study was an observational trial, not a cause-and-effect trial. So it can’t say how, or even if, these supplements actually increase a woman’s chance of dying. Contradicting other recent meta-analyses on calcium, this mineral seemed to reduce a woman’s risk of dying.

The notion that the use of some supplements increases your risk for mortality is not substantiated by this data. In a statement by Duffy MacKay, N.D., vice president, scientific and regulatory affairs for the Council for Responsible Nutrition (CRN), he notes, “It’s important to keep in mind that this is an associative—not a cause and effect—study.  Further, the authors themselves have noted additional limitations.  In fact, when the authors did their initial [minimum adjusted] analysis, it appears they actually found benefit for many of the supplements, not just calcium; yet instead of stopping there, they went on to “further adjust” the data, possibly until they found statistics worthy of this publication’s acceptance.  The study may make for interesting scientific water cooler discussion, but certainly does not warrant sweeping, overstated concerns for elderly women.”

It should be noted that one of the supplemental nutrients associated with increased mortality risk is Iron. It is already well established in the literature that iron is not recommended for post-menopausal women and men and that excess can increase the risk of liver and heart disease.  Based on this research, Rainbow Light® has offered iron-free products for years, including: Active Senior™, Menopause One™, 50+ Mini Tab™, Complete Menopause™, Rejuvenage 40+™, and Women’s Answer™.  Products marked with our Safeguard™ guarantee are not only free of iron, but also nutrients contraindicated with common medications taken by 50+ consumers, heart patients and cancer survivors.  It is always advised to check with a doctor to assess iron-deficiency prior to considering a supplement with iron.

An additional point made in the ‘editorial note’ that can strongly be agreed with is that “a better investment in health would be eating more fruits and vegetables, among other activities.” Getting our nutritional needs through food is truly the key to adequate nutrition, however, few can say they meet the micronutrient nutritional guidelines of 5-9 servings of fruits/vegetables daily, which is why many take a multivitamin. It should also be noted that the American Medical Association recommends multivitamin supplementation for our fast-paced society.

Rainbow Light multivitamins offer the highest standard of purity and potency researched for a long and healthy life, with science-backed potencies of Vitamin D (important for immunity, bone health and breast and colon health), B-complex (important for brain, stress and heart health) in a concentrated food base and with additional digestive support for best assimilation and to prevent stomach upset.  All of our multivitamins are produced in FL in a GMP facility in Sunrise, FL with strict purity testing of inbound raw materials and finished goods.
