The Dr. Layne Norton Podcast The Most Overhyped Supplements of All Time
Mar 30, 2026
A straight‑talk breakdown of supplements that promise more than they deliver. Topics include BCAAs versus total protein, HMB’s limited uses, glutamine and arginine’s poor oral impact, and the plant steroid hype around ecdysterone and turkesterone. Practical takes on electrolytes and why creatine monohydrate still wins are also discussed.

Episode notes
BCAAs Don’t Beat Adequate Total Protein
- BCAAs stimulate muscle protein synthesis but don't build more muscle than sufficient total protein.
- BCAAs lack other essential amino acids so MPS short-circuits; whey or total protein outperforms isolated BCAAs in RCTs.
HMB Works As Anti Catabolic Not Anabolic
- HMB is anti-catabolic and may reduce muscle breakdown but is not an anabolic steroid substitute.
- Benefits appear in wasting or untrained/elderly populations; trained adults see no added hypertrophy or strength gains.
Layne’s Glutamine U-Turn From Boards To PhD Lab
- Layne admitted he used glutamine in the early 2000s and later learned most oral glutamine is extracted by gut and liver.
- Research shows 80–90% first-pass extraction so oral glutamine rarely raises peripheral levels or performance.
