What actually l-citrulline is?

Citrulline occurs naturally within the human body and is created as a by-product when nitric oxide is produced from the amino acid arginine.

For this reason, citrulline acts essentially as a precursor to nitric oxide production, promoting vasodilation and helping to stimulate the circulatory system.

There are some who argue that citrulline actually promotes greater arginine production in the body than arginine supplements themselves.

This, in combination with the increased production of nitric oxide, helps to improve muscle nitrogen retention and improve the overall rate of muscle protein synthesis.

Some natural sources of citrulline are fruits, especially watermelon.

What’s more, citrulline should not be used by pregnant or breastfeeding women, nor should it be used by individuals under the age of 18.

Consult your doctor or physician prior to using citrulline if you have any pre-existing medical conditions or if you are currently using prescription medication.

Final Word

When considering which citrulline supplement to use it is well worth taking a look at the form of citrulline provided.

Citrulline Malate is typically used in a 1:1 ratio, which means that for every 3 g of ingredient you are receiving a total of 1.5 g of citrulline and 1.5 g of malic acid.

You should take this into consideration when choosing your citrulline supplement because by the time you use enough to receive an effective dose, you may find yourself receiving fewer actual servings than are reported on the product label.

L-Citrulline is an arguably superior choice due to its 100% citrulline content, and this is another reason that KAGED MUSCLE Citrulline is the top citrulline supplement this year.
