Anti-Fatigue Caps are a key part of the Race PB Kit because they’re designed to help you stay strong when sessions get long and legs get heavy.
WHAT ANTI-FATIGUE DOES:
- Helps fight “heavy legs” by supporting the body’s cleanup of exercise ammonia (a fatigue by-product).
- Supports sustained endurance so you can keep output steadier in long workouts/races.
- Helps energy production by supporting glycogen availability (your main endurance fuel).
- May help reduce cramping risk by supplying key minerals and supporting muscle function.
- Vegan + gluten-free and made with vegetable capsules.
Why ammonia matters
During long endurance efforts, the body can build up ammonia from protein metabolism. Too much ammonia is linked with that “flat” feeling—when energy drops and legs feel like concrete. Anti-Fatigue Caps are built to help mop that up so you can keep moving.
PRODUCT INGREDIENTS:
1) Potassium / Magnesium Aspartate
- Supports stamina + metabolism
- Helps the body handle excess ammonia
- Supports energy pathways involved in endurance output
2) OKG (Ornithine Alpha-Ketoglutarate)
- Helps increase glutamine availability without adding extra ammonia
- Supports muscle preservation during long efforts
- Acts as an ammonia scavenger
3) EES™ enzymes (10 mg per capsule)
- Helps absorption and assimilation of the key nutrients (so you get more out of each cap)
Extra everyday benefit
Not only for racing: the formula can also support general fatigue (including “run-down” days), because the same fatigue by-products show up when life gets hectic.
