Best Gut Health & Digestive Enzymes for Athletes

High-protein intake (>1g/lb) and heavy compound lifts increase splanchnic hypoperfusion, damaging intestinal microvilli and reducing amino acid assimilation. We audited leading formulations for stomach-acid survival, enzyme units (HUT/SAPU), and pharmaceutical-grade mucosal repair compounds.

Standard 1: Spore Survival
99.4% Survival

Spore-forming bacilli bypass pH 1.5 stomach acid without degradation.

Standard 2: Enzyme Activity
6,000+ HUT

Verified protease potency hydro-cleaves dense whey peptide chains.

Standard 3: Barrier Repair
5,000mg L-Gln

Direct enterocyte fuel prevents endotoxin leakage during intense cardio.

7 Billion CFU Spores • 150mg DigeZyme® • 5,000mg L-Glutamine

Soil-based spore-forming bacilli (LactoSpore & DE111) bypass low-pH gastric acid to colonize the ileum and colon. Patented DigeZyme enzymatically hydrolyzes heavy protein shakes to eliminate fermentation, bloating, and endotoxin translocation.

SPORE CFUs 7 Billion CFU ✓ Assayed
ENZYMES 150mg DigeZyme® ✓ Full-Spectrum
L-GLUTAMINE 5,000mg USP ✓ Pure Micronized
ABSORPTION +41% AstraGin® ✓ Double-Blind
Clinical Advantages
  • ✓ Acid-resistant spore bacilli survive pH 1.5 gastric transit intact.
  • ✓ Broad-spectrum DigeZyme hydrolyzes dense whey & casein peptides.
  • ✓ Clinical 5g L-Glutamine protects tight junctions during heavy lifts.
Considerations / Limitations
  • ✕ Premium clinical formulation price point compared to generic probiotics.
