Citrulline Supplements Guide

L-Citrulline and Citrulline Malate are very popular supplements used by athletes and bodybuilders to help enhance performance and recovery from training.

What is Citrulline?

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 promote greater arginine production in the body then arginine supplements themselves.

Citrulline also elicits a similar effect to that of creatine monohydrate supplements, increasing intra-cellular production of adenosine triphosphate or ATP.

ATP acts as a form of currency or medium for the exchange of energy between cells. Increasing the concentration of ATP in your cells gives your body access to more energy, thereby enhancing, strength, endurance, and overall physical performance as a whole.

Some natural sources of citrulline are fruits, especially watermelon.

Always speak with a medical professional or doctor before taking any supplements. Always read the product label for instructions and directions.

Taking Citrulline

Always follow the usage guidelines provided by the manufacturer on any supplement you purchase.

Citrulline is most commonly used as a pre-workout or intra-workout supplement in order to stimulate blood flow and prepare your body for intense training.

It can also be used away from your workouts in a similar manner to supplements like creatine.

Because of its vasodilatory effects, citrulline should be avoided by anyone who has ever suffered a heart attack or other form of cardiovascular disease.

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, especially if you have any pre-existing medical conditions or if you are currently using prescription medication.

Please note that these statements have been neither written nor reviewed by a doctor or medical authority of any kind.

What to Look for in a Good Citrulline Product

There are a few different forms of citrulline on the market, including L-Citrulline and Citrulline Malate.

There does not appear to be a great deal of difference between these forms of citrulline when it comes to effectiveness, so we recommend basing your decision more on what you can fit into your budget and of course which products have received the best feedback from users.

You will also want to make sure that you choose a citrulline supplement that actually delivers an effective dose of the active ingredient.

It is an unfortunate fact of the supplement industry that many manufacturers rely on a proprietary blend, in which case you will have no idea how much of the active ingredients you are actually receiving.

Choosing a stand-alone citrulline supplement, or at least one that displays how much citrulline is included, will ensure you are able to actually reap the benefits that citrulline has to offer.

(The effective dose of Citrulline Malate appears to be 2 – 6 g, depending on your body weight.)

If there is a particular supplement brand that you are already familiar with due to having used some of their other products then you might want to consider choosing their citrulline supplement to give you a little extra peace of mind.

To sum it up, look for:

  • Quality and Amount per serving
  • Ingredients and Percentages
  • Feedback from online users and reviewers
  • Quality of production
  • Brand reputation
  • Price per serving

Wrapping Up

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.

Aside from this, you need to think about is whether you want to use a citrulline as a stand-alone product or as part of a larger pre-workout formula.
