inosine

Inosine is a natural substance that may support better oxygen flow throughout the body.* When your cardiovascular system is working hard to send O2 to your tired muscles, inosine may support your body during this crucial time.*

Inosine is a purine nucleoside that works with ribose to form the building blocks of ATP, DNA and RNA, all important in generating new cells and energy.* Metabolically, inosine is an intermediate in a number of purine nucleotide pathways that affect the ability of the muscle to work efficiently and therefore may have a positive effect on overall physical strength and energy during exercise.*
