About this supplement

Sustained-release beta-alanine is a modified form of the non-essential amino acid beta-alanine designed to prolong its release and absorption in the body. Unlike standard beta-alanine, which is rapidly absorbed and can cause acute paresthesia (tingling sensation), sustained-release formulations utilize specialized delivery systems (e.g., microencapsulation, polymer matrices, or time-release tablets) to gradually release beta-alanine into the bloodstream. This aims to maintain more stable plasma levels, potentially improve tolerability by reducing side effects, and enhance muscle carnosine loading over time. Beta-alanine is a rate-limiting precursor to carnosine (β-alanyl-L-histidine), a dipeptide that buffers hydrogen ions in skeletal muscle, thereby delaying fatigue during high-intensity exercise.

How much to take

Typical amount
Typically 2-6 grams daily, often split into smaller doses (e.g., 800-1600 mg) taken multiple times per day, even with sustained-release forms, to optimize carnosine loading over 2-4 weeks.
Suggested range
800-1600 mg per serving, 2-4 times daily (total 3.2-6.4 g/day) during loading phase; 1.2-3.2 g/day for maintenance.

Formula

C3H7NO2

Physical properties

Typically appears as a white, crystalline powder. The sustained-release form is often processed into granules, microcapsules, or tablets with coating/polymer matrices to control dissolution. Soluble in water. Odorless.

How it’s made

Produced synthetically via chemical synthesis, often from acrylonitrile or via microbial fermentation. The sustained-release property is achieved through pharmaceutical manufacturing techniques such as microencapsulation (coating beta-alanine particles with polymers like ethylcellulose), embedding in a hydrophilic or hydrophobic matrix, or creating multi-layer tablets with slow-dissolving barriers.
