According to the U.S. Food and Drug Administration (FDA), vitamin B dietary supplement Healthy Life Chemistry By Purity First B-50 contains two anabolic steroids—methasterone and dimethazine—and should not be purchased or used by consumers. Purity First Health Products has apparently declined to voluntarily recall the product or issue consumer warnings despite alleged adverse incident reports, including “fatigue, muscle cramping, and myalgia, as well as abnormal laboratory findings for liver and thyroid function, and cholesterol levels.” FDA warns that these steroids can cause acute liver injury, unwanted hair growth in women and infertility in men. The agency further advises health care professionals to ask their patients about dietary supplement use, particularly in patients with certain signs associated with steroid use, and to report any adverse reactions through FDA’s MedWatch program.
