Product Overview

Bodybuilding.com Signature Citrulline

Citrulline is a naturally occurring amino acid that supports the production of the amino acid arginine. Increased arginine leads to increased nitric oxide (NO), a vasodilator that opens up blood vessels and increases oxygen and blood flow throughout your body. That’s what fans refer to as pumps!*

CITRULLINE

L-Citrulline is the natural form of citrulline. Your body produces it, but supplementing can help you have a killer workout.* As detailed above, citrulline aids in blood vessel dilation. This lets more oxygen and nutrients hit your hard-working muscles. Citrulline also keeps you going strong by helping your body eliminate ammonia. Ammonia, a byproduct of protein synthesis, causes exercise-related fatigue.*

Studies have shown improved power output, oxygen consumption, and exercise performance with just 2.4 grams per day over an eight-day period.[1,2]* Feel good about the fact that Signature Citrulline contains no filler and no other ingredients – just 100% pure Citrulline. It’s also vegan and sourced in the U.S.A.

WHY NOT SKIP A STEP
AND JUST TAKE ARGININE?

Citrulline goes straight to your bloodstream, while arginine must go through a less efficient digestion process.

HOW TO USE CITRULLINE

Signature Citrulline is nearly flavorless and can be mixed with water, juice, or any other beverage. You can also add it to your favorite pre-workout product.

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, Bodybuilding.com was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.

TOTAL TRANSPARENCY

Signature products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend”, so you always know exactly what you’re putting into your body.

EFFECTIVE DOSES

An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. Signature supplements always include enough to get the job done.

RESEARCH-BACKED INGREDIENTS

Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in Signature products because that’s what works.

I am almost through with my first tub of this stuff and will definitely get more. I received crazy overall vascular improvements while taking this. I debated whether to get Arginine to add to my stack, but I don't see how I could get any more improvements than with this straight Citrulline. You'll also probably see a lot of talk online about getting Citrulline Malate or just the straight Citrulline. You can weight the pros and cons of that, and use what works for you, but for overall performance and getting your blood transporting all the good stuff to your brain and body, this supplement is legit. Pros (besides the overall benefits): mixes easily--like just pour some water on it and it's nearly dissolved, nearly tasteless, has a desiccant pack in it to keep it from clumping or absorbing moisture, includes a scoop to measure your intake. I've tried many of the Signature Series products, and this is probably my favorite for overall noticeable effectiveness.

I've been taking a scoop a day, three on days I workout and I can deff say I feel it! I get a good pump and can feel the blood rushing to my muscles! Love it! I mix it with my pre or bcaa cause in straight water it tastes a bit strange to me at least.

I started using signature citrulline a couple of months ago because it was cheaper than the citrulline I was using. I am happy with the product thou it is not quite good as the brand I was using before. But for the money I feel it is a good value.

I love this product. It works great with my pre workout. I usually add 6 gr ( 3 scoops) and the pump is incredible. Helps the blood flow. I work nights so I usually take 4 gr and mix it with water n helps me stay awake. Bottom line when there is oxygen flow in your blood everything works better.

Best way to achieve Maximum Pump is to ensure you have 6g to 7g of Citrulline in the Pre-Workout. Best way to increase that level is with this particular one! Best price for the quantity on the market.

To the best of my knowledge the product is doing what it says it will do, I've only been using it for a month and I'm getting larger arms and a bigger chest, I'm almost positive that's what is expected

This product at 6 grams gives great pumps that last the entire workout, and it helps to maximize blood flow. Usually citrulline is sour but this one is not which is great since it doesn't change the flavor of your pre workout. You can tell this is a very high quality product and I think its exactly the same as the Kaged Muscle citrulline only cheaper. Overall, you cant go wrong with this product if your looking for great pumps.
