Pre workout supplements, in particular, are designed to provide a boost of energy and focus before exercising, allowing individuals to push themselves harder and achieve better results.
One ingredient found in some pre workout supplements is DMAA (1,3-dimethylamylamine). DMAA has been found to increase energy and focus, it has also been linked to serious health issues such as heart problems, high blood pressure, and even death.
Many bodybuilders and athletes seek out DMAA supplements and other sports performance supplements in the hopes of improving their physical abilities.
