The Medicines and Healthcare products Regulatory Agency (MHRA) has ruled that the popular DMAA containing sports supplement Jack3D is an unlicensed medicinal product and that it and all other DMAA containing products need to be removed from the UK market amid concerns of potential risks to public safety.
DMAA is most commonly used as a workout aid or weight-loss supplement and can have a physiological effect on the body narrowing the arteries and raising the heart rate; this has been linked to suspected adverse drug reactions worldwide, ranging from shortness of breath to heart attacks. It has also been linked to at least one fatality.
The MHRA has already issued eight urgent notices instructing retailers to remove the product and any other DMAA containing products from sale. The MHRA has recently taken action against a number of products presented as sports supplements that fall within the definition of a medicinal product because of the potent herbal ingredients they contained.
DMAA is also banned under the prohibited list of banned substances by the World Anti-Doping Agency and has been responsible for 137 doping violations worldwide.
David Carter, the Manager of the MHRA’s Medicines Borderline Section said:
“People need to be aware when choosing their sports supplements. These products may claim to increase performance but contain powerful ingredients which can have serious side-effects.
“We recommend that people only use approved products and speak to a qualified medical practitioner if they have any concerns about any supplements they may be taking.”
Graham Arthur, Director of Legal at UK Anti-Doping said:
“This is a significant step forward for all competitive athletes as methylhexaneamine (DMAA) is a banned substance ‘in-competition’ that frequently appears in over the counter and internet bought products but not clearly on the label. Athletes who use sports supplements need to choose reputable manufacturers who can justify their claims with scientific evidence, and have their products screened to minimise the risk of testing positive for a substance on the World Anti-Doping Agency’s Prohibited List. UK Anti-Doping continues to work closely with the MHRA to protect the health of athletes and to prevent doping in sport.”
