The Claim

In male bodybuilding athletes with at least two years of resistance training experience, 21 days of daily beta-alanine supplementation at 6 g/day combined with a standardized resistance training protocol is associated with a 55% increase in blood carnosine levels and a 3.5% increase in lower limb muscle strength compared to a placebo group receiving dextrose.

In plain English

In male bodybuilding athletes with at least two years of training experience, taking 6 grams of beta-alanine daily for 21 days along with a standard weight training program results in a 55% increase in blood carnosine levels and a 3.5% increase in lower limb muscle strength compared to taking dextrose.

See the scientific wording

In male bodybuilding athletes with at least two years of resistance training experience, 21 days of daily beta-alanine supplementation (6 g/day) combined with a standardized resistance training protocol is associated with a 55% increase in blood carnosine levels and a 3.5% increase in lower limb muscle strength, compared to a placebo group receiving dextrose, suggesting that beta-alanine may enhance the physiological response to resistance training in this population.

Why this might work

Taking beta-alanine lets muscles make more carnosine, which soaks up acid that builds up during hard workouts. This keeps muscles from getting too acidic too fast, so they can keep contracting strongly for longer, leading to greater strength gains.

1 study

  1. Study: Effect of beta-alanine supplementation on carnosine amount and muscle strength of the upper and lower extremities of bodybuilding athletes

    In experienced male bodybuilders, taking 6 grams of beta-alanine daily for 21 days along with leg workouts led to a big jump in a muscle compound called carnosine and a small but real boost in leg strength, compared to those taking sugar pills.
