A study published in the peer-reviewed Nutrition Journal (October 24, 2007) reveals that people who used multiple supplements for at least 20 years were in overall better health than both non-supplement users and individuals who only consumed a multivitamin/mineral supplement. This first-ever study on long-term users of multiple dietary supplements found them comparatively to have markedly better health as measured by higher blood levels of key nutrients, more optimal levels of key health biomarkers, and lower prevalence of diabetes and elevated blood pressure.
The objective of the study was to describe the dietary supplement usage patterns, health, and the nutritional status of long-term multiple dietary supplement users, and to make appropriate comparisons to matched single multivitamin supplement users and nonusers of supplements. Using a cross-sectional design, information was obtained from online questionnaires and on-site physical examinations from a sample of long-term users of multiple dietary supplements from a single dietary supplement supplier (Shaklee).
The group of 278 long-term multiple dietary supplement users consumed a broad array of vitamin/mineral, herbal, and condition-specific dietary supplements on a daily basis for at least 20 years. As a group, they were 73% less likely to have diabetes and 39% less likely to have elevated blood pressure than non-users. Also, this group was less likely to have suboptimal blood nutrient concentrations, and more likely to have favorable levels of key biomarkers, including serum homocysteine, C-reactive protein, high-density lipoprotein cholesterol (HDL’s), and triglycerides than either non-users or multivitamin/mineral users.
“The study results were very impressive and support the potential benefits of long-term use of dietary supplements,” said Gladys Block, PhD, nutrition researcher and Professor of Epidemiology and Public Health Nutrition at the University of California at Berkeley School of Public Health. Dr. Block helped lead the research team in its efforts to conduct the first-of-its-kind study on this unique population of long-term users of a broad array of a single brand of dietary supplements.
