Beta-alanine is a variant of the water-soluble, non-essential amino acid alanine. In dietary supplements, the Beta-alanine variant is primarily used. Alanine is required for the production of L-carnosine and is especially popular among athletes.
Beta-alanine, creatine, and BCAAs are the three supplements most widely used by bodybuilders based on solid research.
The absorption of carnosine by the body is difficult, and levels are particularly low in women and in people who consume as few animal proteins as possible. Supplementation with sustained-release Beta-alanine ensures that the carnosine concentration in the muscles increases.
What's the difference between beta alanine and phenylalanine?
Beta-alanine resembles phenylalanine closely, but the two act in completely different ways. Beta-alanine is one of the most widely used supplements among athletes, whereas phenylalanine is used very little.
| Feature | β-alanine | Phenylalanine |
| Structure | β-amino acid (NH₂ group on the β carbon) No aromatic ring | α-amino acid (NH₂ group on the α carbon) Aromatic benzene ring |
| Incorporated into proteins? | No (non-proteinogenic) | Yes (essential, proteinogenic) |
| Body function | Building block of carnosine → pH buffer in muscle cells | Precursor of tyrosine → dopamine, nor-/adrenaline, melanin |
| Dietary source | Released in small amounts during breakdown of the dipeptide anserine/carnosine from meat/fish | Present in virtually all proteins (meat, dairy, legumes, seeds etc.) |
| Supplement use | Popular in sports: to raise carnosine concentration in muscles | Not widely used |
| Side effects | High dose (≥ 800 mg per serving) → paresthesia (tingling), harmless but uncomfortable | None, except dangerous in PKU (phenylketonuria) |
| Daily requirement | No RDA; 3–6 g/day in divided doses common in sports studies | ± 14 mg/kg body weight (essential) |
