"You can only train as hard as your ability to recover."

 - Dr. Aaron Horschig

Boosting physical performance via the gut

Intense workouts, competing under pressure, and unique diets can all add to the stress athletes experience. Their gut microbiota may be altered, and they may face issues such as GI symptoms, insomnia, chronic inflammation, delayed-onset muscle soreness, and the risk of kidney damage.

Probiotics are already used by some to maintain fitness and boost recovery. The anti-stress, anti-fatigue, and antioxidant properties of PS128 makes it an encouraging prospect for achieving physical well-being.

 

In multiple placebo-controlled studies, researchers in Taiwan have found significant advantages - both during and after competition - from giving PS128 to athletes. Benefits include:

 

  • improved athletic performance,

  • quicker recovery,

  • reduced inflammatory markers and oxidative stress, and

  • increased branched-chain amino acids (BCAAs).

Exercise Capacity Recovery after a Half-Marathon.jpg

Study Summary

  • Type: double-blind, randomized, placebo-controlled, counterbalanced, crossover trial

  • Participants: 8 recreational runners in their 20s, female and male

  • Intervention: 4 weeks of either PS128 supplement or placebo capsule

The PS128 group showed significantly better final-stage split times during their competition (see below), significantly higher leg muscle strength in the days after the race, and significantly lower markers of muscle and kidney damage compared to the placebo group.

Study Summary

  • Type: double-blind, randomized, placebo-controlled, trial

  • Participants: 20 university athletes, male

  • Intervention: 4 weeks of either PS128 supplement or placebo capsule

The PS128 group showed significantly better endurance (by about 130%, see below), significantly improved gut microbiome (decreased "bad" species, increased "good" species), and significantly greater short-chain fatty acids (SCFAs) when compared to the placebo group.

Study Summary

  • Type: double-blind, randomized, placebo-controlled, trial

  • Participants: 34 university athletes

  • Intervention: Either 3 or 4 weeks of either PS128 supplement or placebo capsule before completing either a sprint or full triathlon

Significant differences (see below) included the PS128 group showing enhanced exercise performance, alleviated oxidative stress and muscle damage post-competition, reduced inflammatory and increased anti-inflammatory cytokines, and raised branched-chain amino acids (BCAAs), as compared to the placebo group.
