Increasing evidence indicates that proper gut microbiome balance improves an athlete’s performance, recovery, and wellness. The synergistic strains in STRONG are clinically proven to balance the gut microbiome. This microbiome balance reduces gut related issues (such as intolerances during endurance exercise), illness, and other setbacks through better gut health, overall wellness, nutrient absorption, and immune system function. STRONG probiotic has been shown to reduce muscular lactic acid production and thus less accumulation which enables your muscles to fatigue more slowly, translating to improved muscle endurance and the ability to better sustain high performance levels. All these factors contribute to better wellness, better recovery, and better performance.

Our premium STRONG probiotic blend is designed to help athletes reach peak performance by reducing lactic acid production and accumulation, improving overall wellness, and reducing recovery time. A 2018 study “showed that [STRONG’s] probiotic significantly reduced postexercise blood lactate concentration,” this translates to improved muscle endurance and ability to sustain high performance levels. The unique and proprietary formula also contains Leucine and Taurine, which are key amino acids for building and repairing muscles. STRONG was crafted using real science backed by real results, that is why it produces real benefits.  

STRONG Probiotic Mode-of-Action

  • Balance gut microbiota with proper dosing of the right strains (200 billion CFU’s)
  • Selection advantage of lactate-utilizing bacteria
  • Strengthen intestinal barrier function, protecting against pathogens
  • Modulate the immune response
  • Produce beneficial bioactive metabolites (e.g., short chain fatty acids and neurotransmitters)

Athlete Benefits

  • Improved gut microbe richness
  • Reduced lactic acid production and accumulation
  • Regulated muscle metabolism
  • Improved energy, energy utilization, and energy storage 
  • Reduced gastrointestinal symptoms during endurance training
  • Improved post-exercise recovery

70-80% of the immune system is found in the gut. Naturally, athletes can suffer from immune depression due to high training load, stress, disrupted sleep, and environmental extremes; combined with being in high exposure situations – crowd exposure, travel, training or competition locations, etc. – athletes are, in short, vulnerable to acute illness.

30-70% of athletes experience some type of gut related disturbance. Athletes are especially susceptible to increased gut permeability due to intense and prolonged exercise, especially when training in the heat. STRONG can protect you from gut troubles without sacrificing your performance or training.


Dedicated to the science of gut health and leading innovation, LYVECAP goes above and beyond with a proven team invested in improving gut health for all.
