Safety of creatine supplementation

Area of Science:

• Sports Medicine
• Nutritional Science
• Pharmacology

Background:

• Creatine supplementation efficacy is well-documented in diverse populations.
• Safety is paramount in therapeutic agent development.
• While generally well-tolerated short-term, isolated reports link creatine to side effects.

Purpose of the Study:

• To review the safety profile of creatine supplementation.
• To assess reported adverse events across various organ systems.
• To evaluate the current evidence on creatine's long-term consequences.

Main Methods:

• Systematic review of existing literature on creatine supplementation.
• Analysis of clinical studies in healthy volunteers and patient populations.
• Examination of reported side effects affecting skeletal muscle, kidney, and gastrointestinal tract.

Main Results:

• Most clinical studies report no increased incidence of side effects with creatine.
• No clinically significant deviations in renal, hepatic, cardiac, or muscle function observed.
• Limited data exists regarding the long-term safety and consequences of creatine use.

Conclusions:

• Creatine supplementation appears safe for short-term use in most individuals.
• Further research is needed to establish long-term safety and potential side effects.
• The overall evidence suggests a favorable safety profile, but vigilance is required.
