Carnosyn beta-alanine (sustained release)

Performance · Endurance · Muscle endurance
Tier 2 — Promising

What it is

The sustained-release form of beta-alanine eliminates the paresthesia (skin tingling) side effect while providing the same muscle carnosine loading. ISSN confirms beta-alanine improves exercise capacity in efforts lasting 1–10 minutes. The Saunders et al. 2017 BJSM meta-analysis (40 trials) confirmed significant performance benefits, especially in efforts of 30 s to 10 min. Requires 4–6 weeks of daily loading to saturate muscle carnosine stores.
