Straight Facts: How To Increase Muscular Endurance Using Citrulline

by Austin Letorney Published on Jun 26, 2025

Can citrulline be the added “spice” to improve your bodybuilding workouts?

STRAIGHT FACTS WITH JERRY BRAINUM – is an in depth exploration of the more complicated elements behind bodybuilding training, nutrition, and supplements. Hosted by legendary and longtime industry expert, Jerry Brainum, Straight Facts answers user questions so no one is left in the dark.

A major problem with a lot of supplements in powder or pill form can be that they don’t absorb into your system as well as when the nutrient occurs naturally. This can lead to people mindlessly taking supplements that actually do nothing. Citrulline does not fall under that category. Naturally existing in watermelon, this amino acid can also be taken as a supplement and it actually works to improve your muscular endurance and reduce fatigue.

In this post, Generation Iron Expert Jerry Brainum exclusively breaks down recent studies that show how Citrulline can help improve muscle endurance.  That means you can spend more time in the gym lifting at peak volume. That means bigger gains. That means a better physique.

Best Citrulline Supplement: Nutricost L-Citrulline Malate

If you’re looking for pure, high-quality citrulline without any additives, Nutricost L-Citrulline is the top choice. Unlike citrulline malate, this supplement contains only L-Citrulline base powder, ensuring you receive the essential amino acid without additional compounds.

  • Key Benefits:
    • 600 grams of pure L-Citrulline powder per container
    • 3 grams per serving
    • 200 servings per container
    • Non-GMO and gluten-free
    • Manufactured in a GMP-compliant, FDA-registered facility

This citrulline is ideal for those looking to maximize muscle endurance, improve blood flow, and support recovery without unnecessary fillers.

Final Thoughts

When it comes to performance-enhancing supplements, not all are created equal—and not all are absorbed effectively. But citrulline stands out as a research-backed amino acid that delivers real, noticeable results. Whether you’re pushing through high-volume training sessions or simply aiming to boost endurance and recovery, citrulline can be a game-changer.

Nutricost L-Citrulline offers a clean, potent, and trusted option for athletes who demand results without the fluff. With 600 grams of pure L-Citrulline, it’s one of the best choices for maximizing muscular endurance, enhancing pumps, and supporting faster recovery between workouts.

If you’re serious about training hard and seeing progress, citrulline should be in your stack—and Nutricost is a solid place to start.
