Creatine Monohydrate

What it is

Creatine Monohydrate is a naturally occurring nitrogenous organic acid synthesized from arginine, glycine, and methionine. In human tissue, approximately 95% of creatine is stored in skeletal muscle as phosphocreatine. Phosphocreatine acts as a rapid energy buffer, donating a phosphate group to ADP to regenerate adenosine triphosphate (ATP) during short bursts of high-intensity explosive movement. Creatine monohydrate is the most thoroughly researched, stable, and bioavailable form used in athletic and cognitive health formulas.

Also known as: Creatine, Creatine Monohydrate Micronized

What it does

• Rapidly regenerates ATP during short-duration, high-intensity exercise.
• Increases peak muscle strength, power output, and lean body mass.
• Supports brain bioenergetics, mental fatigue resistance, and cognitive speed.

Amplified by probiotics

Creatine monohydrate is absorbed across the intestinal brush border via the sodium- and chloride-dependent creatine transporter CRT1 (SLC6A8). Live probiotic bacteria enhance gut barrier integrity through SCFA production (butyrate, acetate) and preservation of mucosal tight junctions (ZO-1, occludin). By attenuating gut lumen inflammation and maintaining optimal intestinal perfusion, probiotics prevent inflammatory suppression of CRT1 transporters and improve intestinal creatine uptake efficiency. Furthermore, lactobacilli lower colonic pH, preventing unwanted degradation of oral creatine into inactive creatinine prior to absorption, thereby optimizing intracellular phosphocreatine loading in muscle and neural tissue.

Typical dose

3–5 g/day (daily maintenance dose)

The evidence

The ISSN position stand confirms creatine monohydrate as the single most effective ergogenic nutritional supplement available for increasing high-intensity exercise capacity and lean mass (Kreider et al. 2017, J Int Soc Sports Nutr). Systematic reviews confirm robust efficacy across explosive sport performance, muscle recovery, and neuroprotective brain energetics (Forbes et al. 2021, Nutrients).
