Some of the most popular supplements today are the so called pre-workout nitric oxide (NO) boosters 1, 2. These contain a panoply of ingredients, but the main one is arginine. The rationale goes that arginine is a nitric oxide (NO) precursor and NO is a potent vasodilator 3, 4, which in turn supposedly will boost blood flow to exercising muscles, performance and recovery.

Mitochondria are the ‘energy powerhouse of the cell’ that convert the foods we eat to usable energy our body uses to fuel life sustaining reactions within cells, our daily activities and athletic performance 1-4. While energy production capability and muscle performance might seem to be more relevant to sports, it also equally important for achievement and maintenance of health throughout the life span. In this article I will describe how chronological aging affects our mitochondria, its implications and the ins-and-outs of a new type of supplements marketed at “exercise mimetics”.
