Ribose is a type of sugar that is naturally occurring in the body and plays a role in energy metabolism. It is a key component of adenosine triphosphate (ATP), which is the primary source of energy used by cells in the body.
In protein powders, ribose is sometimes added as an ingredient to help improve athletic performance and reduce muscle fatigue. It is believed that by providing an additional source of ribose, protein powders may help increase the production of ATP in the body, thereby improving energy levels and reducing fatigue.
While ribose is generally considered safe when consumed in moderate amounts, high doses of the sugar may cause digestive side effects like nausea, diarrhea, and stomach cramps.
