The Claim

Citrulline/malate supplementation for four weeks does not significantly alter resting blood lactate levels in active handball players, indicating that its influence on lactate is limited to exercise-induced production and not baseline metabolic regulation.

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

Taking citrulline/malate supplements for four weeks does not change resting blood lactate levels in active handball players, meaning the supplement affects lactate only during exercise, not at rest.

See the scientific wording

Citrulline/malate supplementation does not significantly alter resting blood lactate levels in active handball players after four weeks of training, indicating its effect is specific to exercise-induced lactate production rather than baseline metabolism.

Why this might work

During exercise, citrulline and malate help muscle cells process lactate faster by boosting the mitochondria's ability to use it as fuel, but they don't change how much lactate is made when the body is at rest.

1 study
  1. Study: The Effect of Citrulline/Malate on Blood Lactate Levels in Intensive Exercise

    Taking citrulline/malate didn’t change lactate levels when the players were just sitting around, but it did lower lactate after they exercised—meaning it helps during activity, not at rest.
