1MR Pre-Workout Boost – It’s AWESOME, But…

40+ Fitness Editor Mike talks about 1 M.R. – a popular pre-workout supplement. This review is on the OLD version of 1MR which is hard to find. The old version of 1MR is NOT the “Original 1MR” – that name refers to the NEW version of 1MR.

The reason 1MR was changed has to do with the ingredient called DMAA. This ingredient received an FDA warning in 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.
