Before we announce what the best citrulline malate is, we must first understand what it is and how and why we would want to supplement it. Citrulline malate is a compound formed when Citrulline, a nonessential amino acid, is bound to malic acid.
L-citrulline is one of the three dietary amino acids in the urea cycle, alongside L-arginine and L-Ornithine. Citrulline actually seems to lead to higher and more consistent levels of arginine than taking L-arginine directly. Citrulline is not easily obtained through diet, so consciously supplementing it is useful to experience the benefits and to avoid one of the common side effects of arginine, which is stomach upset. In supplement form, citrulline is typically extracted from watermelon.
The health benefits of citrulline include:
- Increased NO production
- Improved blood vessel health and vasodilation
- Reduced lactic acid build up
- Increased ATP production
- Modest reduction in blood pressure
- Might have a beneficial effect on erectile dysfunction
- Supports the immune system
So, as far as l-citrulline vs citrulline malate goes, why do we add the malic acid? Malate plays into the Tricarboxylic Acid (TCA) Cycle. This helps us produce ATP so that muscles can continue working. It works synergistically with the citrulline.
6-8 grams of citrulline malate is sufficient to induce an ergogenic effect, though doses as low as 3g still offer performance benefits. It is worth noting that if a supplement contains l-citrulline (no malate), a lower dose can be used as this form of citrulline is pure, not at (usually) a 2:1 ratio.
Citrulline malate is commonly found in pre-workout supplements but may also be used intra-workout in combination with supplements like BCAAs.

Citrulline malate when taken as a dietary supplement will allow you to train harder and longer by increasing nitric oxide production, removing unwanted ammonia and facilitating aerobic metabolism so that you can train longer and harder before fatigue sets in.
Citrulline supplementation can be of benefit to anyone for increasing nitric oxide levels and exercise performance, in addition to reducing post-workout muscle soreness. The easiest way to take your citrulline is with a simple standalone powder with no additives or fillers although you may use it in a formula like a stimulant pre-workout for other benefits such as increased energy levels.
