Lactic Acid Buffer6Published Studies20+Years in Sport Science★ 5.0Average Customer RatingThe ScienceHow L.A.B Works
01
Acidity Builds UpDuring hard efforts — a Hyrox run station, a SkiErg sprint, a heavy lifting set — hydrogen ions flood your muscles. That burning sensation forcing you to slow down? That's the problem L.A.B solves.
02
L.A.B Neutralises the BurnThe formula raises your body's natural buffering capacity. Take 3 tablets in the morning and 3 in the evening with food — each bag is a full month's supply. No loading phase, no complicated timing.
03
You Push Harder & Recover FasterResults typically felt within 2–4 weeks. Back-to-back training becomes manageable. Race day efforts feel more controlled. Recovery between stations improves noticeably.
Why Athletes Choose L.A.BBuilt for the Demands of Hybrid Sport
-
Reduce Muscular Fatigue Mid-Effort
Buffer the acid build-up during your hardest intervals and race stations — push through when others slow down.
-
Faster Recovery Between Sessions
Train more consistently without the heavy, tight legs. Ideal for Hyrox athletes managing high volume and frequency.
-
Backed by Published Science
Not a blend of standard ingredients. L.A.B is backed by independent science — six published studies on its specific formulation.
-
Clean & Informed Sport Compliant
Safe for competitive athletes. No banned substances, no proprietary blends, no nonsense.
