L-citrulline and l-arginine supplements are booming in the workout industry because of their vast benefits, especially in their production of nitric oxide.* Nitric oxide has been proven to get bigger gains and pumps during workouts, as well as a quicker recovery time.*
Various workout supplements include both l-citrulline and l-arginine, while others choose one or the other.
What is the difference between the two?
L-Citrulline vs. L-Arginine
First off, both are Amino Acids that the body naturally creates. They also both help to lower blood pressure and are precursors to nitric oxide.* L-Citrulline produces L-Arginine in the Kidney while L-Arginine produces Nitric Oxide in the gut.
L-citrulline differs from l-arginine by its ability to reduce fat levels when combined with exercise.* It not only helps to build lean muscle, but actually shrinks body fat.*
Additionally, it helps to boost and maintain energy levels during and after a workout.* L-citrulline helps to release stored energy in the muscles, called ATP (adenosine triphosphate).* That means, l-citrulline pre workout supplements help to keep your muscles and body energized even after a tough workout.
L-citrulline has also been shown that it is better used to reduce fatigue and lactic acid from the muscles after a workout.* Because it acts as a vasodilator, l-citrulline helps release nitric oxide and allow more blood to flow to the muscles.*
The clinically recommended dosage for l-citrulline pre-workout supplements is 6g per one serving in order for it to benefit the person to their maximum capacity.
L-arginine is an amino acid that helps to build and synthesize proteins in the muscles, which helps them grow and repair quickly.* After a long workout, your muscles will feel that “pump” to let you know that they got worked out.
A difference that l-arginine does is that it induces growth that help rebuild muscles and grow lean muscle quickly.*
One of the best benefits of l-arginine is that it helps to reduce cortisol,* which is released when you’re stressed. Lower cortisol levels means less stress! And who doesn’t want that?
Which Is Better For Pre-Workout?
Truthfully, both are great to have in a workout supplement since they both perform differently.
However, if you were to choose just one, l-citrulline is better proven to be more effective at producing nitric oxide with lower dosages.* L-citrulline pre-workout supplements that have 6g of the amino acid will help your body build muscle and reduce fatigue to squeeze in a harder workout.*
