Beta-Alanine (CarnoSyn)

Beta-Alanine (CarnoSyn) is a non-essential amino acid with no significant macronutrient contribution at typical supplemental doses (2–5g/day). It contains approximately 4 calories per gram (as an amino acid), yielding roughly 8–20 kcal per standard serving. It is not a source of dietary fat, carbohydrates, or fiber. As a single amino acid, it provides no meaningful vitamin or mineral content. The primary bioactive compound is beta-alanine itself (CAS 107-95-9), which serves as the rate-limiting precursor to carnosine (beta-alanyl-L-histidine) synthesis in skeletal muscle. CarnoSyn is a patented, pharmaceutical-grade form with verified purity ≥99%. Typical supplemental doses deliver 1.6–3.2g per serving, with sustained-release formulations available at 3.2g. Bioavailability is high via oral ingestion, with peak plasma levels reached within 30–45 minutes post-ingestion. Muscle carnosine synthesis requires co-availability of L-histidine (typically sufficient from dietary protein intake). Carnosine concentrations in skeletal muscle increase by approximately 40–80% after 4–10 weeks of consistent supplementation at 4–6g/day. No significant fat-soluble or water-soluble vitamin content is present. Sodium content is negligible (<5mg per serving depending on formulation). The characteristic paresthesia (skin tingling) side effect occurs at plasma concentrations above ~40 µmol/L, typically triggered by single doses ≥800mg.
