Creatine Monohydrate is a well-researched dietary supplement popular among athletes and individuals looking to enhance physical performance. It is a naturally occurring compound derived from amino acids (arginine, glycine, and methionine) and found in small amounts in certain foods, primarily meat and fish. The body also produces creatine endogenously, mainly in the liver, kidneys, and pancreas. Its primary role involves the rapid regeneration of adenosine triphosphate (ATP), the primary energy currency of cells, particularly during short bursts of high-intensity activity. Supplementation with creatine monohydrate increases the body's phosphocreatine stores, thereby improving ATP availability and supporting enhanced performance in activities requiring strength and power. Beyond its well-established role in exercise performance, research is exploring its potential benefits for cognitive function and as a therapeutic agent for various conditions.

Note
GLP-1 medications slow stomach emptying, changing how/when oral supplements absorb; rapid weight loss raises the importance of protein and micronutrients.
Time oral supplements when nausea is lowest; prioritize protein and micronutrients; discuss with your provider.
