Adverse effects of sports supplements in men

Sports supplements are widely available over-the-counter and online. They may contain undeclared substances including androgenic steroids. According to the Australian Sports Anti-Doping Authority almost one in five sports supplements contain banned substances including stimulants and anabolic drugs. It warned that any supplement may not be safe to use. Some supplements contain large amounts of protein or creatine. Their use may cause a raised blood urea or creatinine in an otherwise healthy individual. Androgen deficiency with symptoms of hypogonadism may be due to use of androgenic steroids. This may be inadvertent as the labels on the sports supplements may not list steroids in the ingredients. If a person admits to using sports supplements it is an opportunity to discuss their health and fitness. The Australian Sports Commission has advice on building muscle and the use of supplements.
