Texas A&M Study Links Creatine Supplementation to Muscle Gains Without Exercise
Daily creatine supplementation can help adults build lean tissue and increase strength even without a structured workout routine, according to a 12-week clinical trial conducted by researchers at Texas A&M University. Published in the Journal of the International Society of Sports Nutrition and reported by outlets including Click2Houston, the study evaluated 64 participants aged 45 to 65 who were randomly assigned to take either 10 grams of creatine monohydrate daily or a placebo.
Non-Exercising Participants Gain Lean Tissue in Clinical Trial
Participants who took creatine without participating in structured exercise gained approximately 2.4 pounds of lean tissue over the 12-week trial period, as detailed by Medical News Today. Richard Kreider, PhD, professor and director of the Exercise and Sport Nutrition Lab at Texas A&M, explained to Medical News Today that creatine monohydrate increases energy in the muscle, which may correspondingly increase non-exercise physical activity and functional activities.
By comparison, participants who combined the same daily creatine supplement with a structured training program and a calorie-deficit diet gained between 2.8 and 3 pounds of lean tissue, according to findings cited by Medical News Today. Both groups taking creatine demonstrated measurable improvements in muscular endurance and strength metrics, including leg press and bench press performance, though exercising participants achieved more significant gains in those areas.
Supplementation Preserves Muscle Mass During Calorie Deficits
Researchers structured the trial with an American Heart Association-guided diet consisting of 55% carbohydrates, 15% protein, and 30% fat to induce a daily calorie deficit of 300 to 500 calories. Fox News noted that while dieting can accelerate muscle loss, daily creatine supplementation helped counter this effect by preserving lean body mass while enhancing fat loss.
Dr. Kathy Nguyen with Memorial Hermann Medical Group, speaking to Click2Houston, stated that maintaining muscle mass is vital during weight loss and noted that she frequently recommends creatine to patients taking GLP-1 medications so they can maintain that muscle mass and not lose the wrong type of weight from our muscles. Beyond muscle preservation, the study observed favorable changes in participant blood fats, glucose control, and cognitive function metrics over the 12-week period.
Expert Recommendations and Dosage Guidelines for Adults
Dr. Kathy Nguyen recommends creatine monohydrate for adults aged 18 and older who want to maintain muscle mass, suggesting a daily intake of 3 to 5 grams. NewsNation reported that obtaining the study’s experimental dosage of 10 grams through diet alone would require eating roughly 5 to 10 pounds of meat or fish daily, making commercial supplements a more practical and economical option.
Medical experts emphasize that individuals should consult a physician before adding creatine to their daily routine, particularly if they manage underlying health conditions or take medications.
