CONSUMERLAB.COM REPORTS DEFICIENCIES IN SOME SUPPLEMENTS CONTAINING CALCIUM, VITAMIN D, OR VITAMIN K
"The new test reports help consumers understand which supplements are accurately labeled and which are not, as well as whether or not a supplement may help them and at what dosage," said Tod Cooperman, MD, President of ConsumerLab.com. The reports also discuss key differences among the many chemical forms of the supplements now marketed, such as vitamins D2 and D3, vitamin K1 and K2(including menaquinone-4 and -7) and the many forms of calcium including calcium carbonate and calcium citrate.
ConsumerLab.com's results appear in three separate Product Review reports: Calcium Supplements, Vitamin D Supplements, and Vitamin K Supplements. The reports cover single-ingredient and combination products for adults as well as children including tablets, chewables, capsules, softgels, liquids, wafers, and powders. Results are provided for thirty-four products, of which ConsumerLab.com selected twenty-two. Twelve were tested at the request of their manufacturers/distributors through CL's Voluntary Certification Program and are included for having passed testing. Also described are five products similar to ones that passed testing but are sold under different brand names.
