Overview

Citrulline DL-Malate is a dietary supplement compound consisting of the amino acid L-Citrulline bonded to DL-Malate, an intermediate in the Krebs cycle. It is primarily used to increase nitric oxide production, which improves blood flow, and to help clear ammonia from the blood, reducing exercise-induced fatigue. The malate component may also contribute to energy production.

Key Benefits

Boosts Nitric Oxide

L-Citrulline is efficiently converted to L-Arginine in the kidneys, leading to a significant increase in nitric oxide (NO) levels.

Enhances Athletic Performance

Studies show it can increase repetitions performed, reduce the rating of perceived exertion, and increase power output.

Reduces Muscle Soreness

Significantly decreases post-exercise muscle soreness (DOMS) by up to 40% in some studies.

Aids in Ammonia Clearance

Plays a key role in the urea cycle, helping to remove ammonia, a byproduct of exercise that contributes to fatigue.

Dosage & How to Take

The clinically effective dose for performance benefits is 6-8 grams of Citrulline Malate.

PurposeDoseNotes
Endurance & Performance6,000 - 8,000 mgTake 30-60 minutes prior to training. Ensure the product specifies a 2:1 ratio of Citrulline to Malate.
General Health3,000 mgLower doses can be used for cardiovascular health benefits, but performance effects are seen at higher doses.

Best Time to Take

For athletic performance, consume 30-60 minutes before your workout.

With or Without Food

Can be taken with or without food, but may absorb slightly faster on an empty stomach.

Forms & Bioavailability

Citrulline DL-MalateHighAthletic performance and energy production.Typically found in a 2:1 or 1:1 ratio. The 2:1 ratio is more common in sports supplements.
L-Citrulline (Free Form)HighPurely for nitric oxide benefits without the malate.Requires a lower dose (3-5 grams) compared to Citrulline Malate.

Side Effects & Safety

Common

  • Generally very well-tolerated. Some individuals may experience mild stomach discomfort at very high doses.

Rare

  • No significant rare side effects have been reported.

Contraindications

  • Individuals taking nitrates for heart conditions or PDE5 inhibitors should consult a doctor before use.

Interactions

May potentiate the blood pressure-lowering effects.

PDE5 Inhibitors (e.g., Sildenafil)High

Can lead to a significant drop in blood pressure.

Scientific Research

2010Journal of Strength and Conditioning Research

Citrulline malate enhances athletic anaerobic performance and relieves muscle soreness

Supplementation with 8g of citrulline malate resulted in a significant increase in the number of repetitions performed and a 40% reduction in muscle soreness at 24 and 48 hours post-exercise.

Food Sources

Watermelon is the richest natural source of L-Citrulline.
