New from Swanson Premium, Inosine is a fundamental nucleoside with a broad range of functions. It is a precursor to the important energy molecule adenosine, which has made it an attractive supplement for athletes and those with high energy requirements. Inosine also is believed to be active within the nervous system, with benefits for neurological health and neuromuscular function. The inosine molecule includes ribose, a simple sugar recommended for cardiovascular health and energy. Found in yeast products and organ meats, inosine is not widely available in the typical American diet. Our supplemental Inosine gives you 500 mg in each veggie capsule, a healthy level for daily support.
