1. On January 23, 2013, Health Canada warned consumers that certain batches of the Chinese dietary supplements [W.S.] Tian Ma Toutong Wan, Shi Hu Ye Guang Wan (Ye Guang Wan), Nai Chang Ming Yan Pills (Ming Yan Pills), [Fung Shing Pai] Tian-Ma Wan and Bak Foong Pills were found to contain excessive amounts of lead or mercury.
While these supplements are not authorized for sale in Canada, they may be available for purchase by Canadian and U.S. consumers through online retail websites.
Excessive levels of lead can cause abdominal pain, anemia, changes in blood pressure, reproductive disorders such as miscarriage, weakness, concentration problems, weight loss, insomnia, dizziness, and kidney and brain damage. Excessive levels of mercury can cause irritability, tremors, memory loss, insomnia, concentration problems, and kidney and brain damage.
2. On December 17, 2012, Performance Plus Marketing, Inc. issued a recall of male sexual enhancement supplements Libigrow, Libigrow XXXtreme, Blue Diamond, Blue Diamond Platinum, Mojo Nights, Mojo Nights Supreme, and Casanova because they were found to contain undeclared sulfoaildenafil and thioaildenafil.
Sulfoaildenafil and thioaildenafil are chemical analogues of sildenafil, the active ingredient in prescription drugs for the treatment of erectile dysfunction. These ingredients can cause symptoms like headache and flushing, and can interact with medications containing nitrates such as nitroglycerine, resulting in dangerously low blood pressure. Consumers who have purchased these supplements should not take them and should contact their healthcare provider if they have experienced any adverse side effects
3. On October 5, 2012, the FDA issued a warning letter to Food for Health International, LLC following a facility inspection which found the company’s products, including Activz brand Vitamin D, Potassium Iodine, Organic Vitamin C, Whole 9 (a fruit and vegetable meal replacement shake) Control and VMA (a vitamin, mineral and enzyme blend), to be adulterated because they were prepared, packed, or held under conditions that do not meet CGMP requirements for dietary supplements.
In addition, the agency found statements on www.foodforhealthinternational.com that promoted the dietary supplement Activz Control as a drug. The supplement was promoted for blood sugar control, reducing bad cholesterol and decreasing hypertension, and was described on the website with statements such as “…Help body stabilize blood sugar,” “Assists the body by . . . Reducing Bad Cholesterol . . . Decreasing hypertension,” “Avoid blood sugar spikes with a unique blend of phytonutrients . . . that help your body stabilize blood sugar levels . . . .” and “Contains . . . antioxidants to fight free radicals that cause . . . disease.”
4. On January 23, 2013, Health Canada advised consumers not to use certain batches of Muscletech Hydroxystim capsules which were found to contain DMAA (1,3-dimethylamylamine) and have been recalled by their distributor. DMAA can increase blood pressure and the risk of cardiovascular events, and has been linked to at least two deaths. It is not allowed to be sold as a dietary supplement ingredient in Canada or the U.S. (See FDA Says DMAA Can't Be Sold as a Supplement).
Hydroxystim is promoted as a “thermo-stimulant” for an energy and metabolism boost during exercise. According to the Muscletech website, Hydroxystim has been reformulated, and neither DMAA nor geranium oil (sometimes used as another name for DMAA) is listed on the new label
