What it does
Beta-alanine raises carnosine levels in muscle, which helps buffer the burning feeling during hard efforts lasting roughly 1 to 4 minutes. Think hard sets of 10 to 20 reps, or short conditioning intervals.
The tingles
A tingling or prickling feeling on the skin, usually face and hands, is a harmless and well-known side effect called paresthesia. Splitting the dose across the day or using a slow-release product reduces it if it bothers you.
Dose and timing
- 3 to 6 grams per day, split into smaller doses to reduce tingling.
- Take it daily, not just before training, since it builds up over weeks.
- It takes 2 to 4 weeks of daily use to reach useful carnosine levels.
Who benefits most
Lifters doing higher-rep strength work, circuit training, or short hard conditioning get the most out of it. If your training is mostly low-rep heavy lifting or long steady cardio, the benefit is smaller.
