New Study: Butyrate Boosts Strength in Post-Menopausal Women by Healing the Gut

A recent randomized controlled trial, the gold standard in scientific research, offers compelling evidence that sodium butyrate, a gut-health-supporting short-chain fatty acid, can significantly improve muscle strength and physical performance in post-menopausal women.

Over a 12-week period, women taking 570 mg of sodium butyrate daily showed:

• Improved handgrip strength and physical performance

• Faster gait speed

• Reduced markers of intestinal permeability (zonulin) and systemic inflammation (LBP)

• Lower oxidative stress

• Better respiratory muscle strength

Researchers found a strong correlation between the reduction in intestinal leakiness and the increase in physical function, suggesting that butyrate's gut-healing effects are key to its muscle benefits.

This study reinforces the link between gut health and whole-body vitality, especially in women facing age-related declines in strength and resilience.
