New Study DESTROYS Creatine (is it really worthless?)

Summary by Krater

Dr. Mike Israetel reviews a new scientific study suggesting creatine is ineffective for muscle growth beyond water retention, and contrasts its findings with the broader body of literature on creatine and resistance training.

Answers: Is creatine ineffective for muscle growth, or does it actually work?

• Creatine monohydrate supplementation
• Muscle hypertrophy and water retention
• Randomized controlled trials in resistance training
• Mechanisms of muscle growth from creatine
• Myostatin and satellite cell activation

What it concludes

• A recent study concluded that creatine monohydrate supplementation combined with resistance training does not enhance muscle gain beyond initial water retention.
• Creatine alone without resistance training primarily increases lean mass due to intracellular water retention (about 0.5 kg rapid gain) with minimal true muscle growth.
• When combined with resistance training, creatine consistently enhances true muscle hypertrophy beyond water, typically adding 1 to 2 kg of lean mass over 8 to 12 weeks.
• Creatine training increases muscle fiber cross-sectional area (confirmed via biopsies, MRI, and ultrasound) with type II fibers experiencing slightly more hypertrophy.
• Mechanisms of true hypertrophy from creatine include enhanced training volume and performance, cell swelling triggering anabolic signaling, and satellite cell activation with myonuclear addition.
• Creatine reduces myostatin expression, a muscle-growth inhibitor, which serves as a mechanism to promote greater hypertrophic response when combined with resistance training.
