Betaine: The Other Beet Supplement

  • Betaine, or trimethylglycine, is a lesser-known fitness supplement derived from sugar beets, also found in foods like spinach and shrimp, typically consumed at 0.1-0.4g/day in diets.
  • Historically used in the livestock industry to increase meat yield and decrease fat, betaine has shown potential in human studies for improving body composition and performance.
  • Research reveals betaine may enhance fat loss by promoting lipolysis and reducing lipogenesis, and it may aid muscle mass increase through effects on pathways like insulin/IGF-1.
  • Some studies suggest betaine can enhance performance by increasing cellular hydration and protecting cells, possibly boosting strength, power, and endurance in trained individuals.
  • Despite promising outcomes in some small studies, overall effects on strength and power performance are inconsistent, and more research is needed to confirm these benefits.
  • Betaine is found in pre-workout blends but typically not highlighted as a main ingredient. Studies show it may boost lean mass and power output under resistance training conditions.
  • Higher dosages up to 3-6g/day, mimicking successful animal feed applications, might offer more pronounced benefits on lean mass and strength, though safety and efficacy at these levels require further exploration.
  • While not yet proven to deserve top-tier supplement status like creatine, betaine might be worth considering, especially for those focused on body composition and hypertrophy goals.
