Inosine is a nucleoside formed by hypoxanthine attached to a ribose sugar and plays a role in metabolic processes such as the synthesis of purines. In the context of sports nutrition, inosine has been explored for its potential to improve oxygen utilization and enhance muscular endurance, although findings remain mixed.
It may support ATP production and facilitate better oxygen delivery to muscles during exercise, making it a candidate for pre-workout or endurance-support formulas. Athletes have historically used inosine in attempts to delay fatigue and improve performance, particularly in aerobic sports.
Synonyms:
Hypoxanthine riboside
Benefits:
- May support ATP production and energy metabolism
- Potential enhancement of oxygen utilization in tissues
- Could contribute to endurance and stamina under certain conditions
Sources:
Produced naturally in the body as part of purine metabolism; also available in synthetic form in supplements.
Observations:
Usually consumed in capsule or tablet form. Overuse may increase uric acid levels, potentially posing a risk to individuals prone to gout. Should be used cautiously with other purine-rich substances.
