40+ Fitness Editor Mike talks about the current controversy surrounding Jacked 3D. Can you still buy it? Is the formula being changed again? Why is is banned in some places? It all has to do with an FDA Warning (April 2012). According to the FDA, DMAA, also known as 1,3-dimethylamylamine, methylhexanamine, or geranium extract, is an ingredient used in so-called “workout boosters” that is often touted as a “natural” stimulant. DMAA is known to narrow the blood vessels and arteries, which can elevate blood pressure and may lead to cardiovascular events ranging from shortness of breath and tightening in the chest to heart attack, the agency said. According to the FDA, it has received 42 adverse event reports on products containing DMAA. Some of the reports involved cardiac disorders, nervous system disorders, psychiatric disorders and death. Please do your own research to determine if this product is still safe/right for YOU to use.
