The Claim
Beta-alanine supplementation at recommended doses (4–6 g/day) is associated with paraesthesia (tingling) as the only consistently reported side effect, and this effect can be reduced by using divided doses of 1.6 g or sustained-release formulations.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking beta-alanine at recommended doses causes tingling in the skin, and splitting the dose into smaller amounts or using a slow-release form reduces this sensation.

Beta-alanine supplementation at recommended doses (4–6 g/day) is associated with paraesthesia (tingling) as the only consistently reported side effect, which can be reduced by using divided doses of 1.6 g or sustained-release formulations.
When beta-alanine enters the bloodstream, it binds to special receptors on nerve cells that sense touch and temperature in the skin. This binding tricks the nerves into sending tingling signals to the brain, which feels like prickling on the face, neck, and hands. Taking smaller doses or slow-release forms keeps the blood level of beta-alanine low enough to avoid triggering these nerves.
What the research says
1 studyStudy: International society of sports nutrition position stand: Beta-Alanine
Taking beta-alanine can make your skin tingle, especially if you take a big dose all at once, but if you split it into smaller doses or use a slow-release version, the tingling goes away.
