The Claim

Supplementation with 3 grams per day of citrulline/malate for four weeks significantly reduces blood lactate levels during and after high-intensity exercise in active handball players, with a 60.7% greater reduction at peak exertion compared to placebo.

In plain English

Taking 3 grams of citrulline/malate daily for four weeks lowers blood lactate levels more during and after intense exercise in active handball players compared to a placebo, with a 60.7% greater reduction at peak exertion.

See the scientific wording

Supplementation with 3 grams per day of citrulline/malate for four weeks significantly reduces blood lactate levels during and after high-intensity exercise in active handball players, with a 60.7% greater reduction at peak exertion compared to placebo, suggesting a potential role in enhancing metabolic clearance during intense physical activity.

Why this might work

Citrulline and malate together help muscle cells burn sugar more efficiently inside their energy factories, which reduces the buildup of lactic acid during hard exercise by pulling it back into the energy cycle and turning it into fuel.

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

    Athletes who took 3 grams of citrulline/malate every day for a month had much less lactic acid in their blood after hard exercise than those who took a fake pill — meaning their bodies cleared the fatigue-causing chemical faster.
