Best Citrulline Supplements for Pre-Workout, Vegans, and More

Citrulline is a popular pre-workout supplement that may increase blood flow, with some studies suggesting that it might help with power output and endurance during workouts. This non-essential amino acid is produced in the body, and it’s found in nature in legumes, organ meat, and especially watermelon — the name "citrulline" is actually derived from the Latin word for watermelon — and there are dozens of different supplements on the market including powders, pills, and citrulline malate, a form that might be more useful for improving energy production.

Whether you’re looking for a straightforward citrulline supplement, a pre-workout with citrulline, or even a nitric oxide supplement that contains citrulline, we’ve done some digging to find the best citrulline products on the market today. Stick with us to pick one out for yourself, and learn about all the potential benefits citrulline has to offer.

Best Citrulline Overall

This pick hits a lot of the essentials we like to see in a basic supplement like citrulline: It sports a low price, has a clean formulation, and is paired with malic acid, which is why it scored our top spot overall. 

Swolverine Citrulline Malate

With only two ingredients, Swolverine’s Citrulline Malate is a BarBend favorite for potentially delaying muscle fatigue and improving recovery. Its 2:1 ratio of citrulline to malic acid can also allow for quicker absorption, and may help with stamina. Malic acid is a nice addition to the citrulline here because these two ingredients work synergistically to provide a possible boost in power and speed, and might make a difference in vascularity. This formula may help promote the production of nitric oxide, which can help with circulation. One of the great benefits of better circulation is that it can potentially lead to better pumps during your workout, making this an ideal add for pre or intra-workout hydration. 

This product comes in an unflavored option, so it can be added to anything from water to coffee without fear of altering the flavor of your beverage. With 60 servings of 5,000mg of citrulline malate at a $56.99 price point, this supplement comes in a bit more expensive than other options, but the 5,000mg serving size of pure product may make this cost worth it.

Best Citrulline for Nitric Oxide Production

For an option that’s got l-citrulline along with 12 other ingredients that can help pump you up for your workout, Huge Supplements Pump Serum has you covered when it comes to providing nitric oxide production to take your workout to the next level.

Huge Supplements Pump Serum

This preworkout boasts 8,000mg of l-citrulline as the main driver for nitric oxide delivery, but it also contains beet root extract, which is a natural pre-workout due to its high nitrate content. This combination of ingredients could be the pre-workout driver you need to get a great pump during your workout. With the options of Jungle Juice, Strawberry Mojito, Cherry Berry, and Island Dream flavors, you have four delicious flavors to choose from. 

Huge Supplements Pump Serum rings in at $54.95 for a tub containing 25 servings, making it a middle ground priced option for pre-workout. Because the clinically effective dose of citrulline is between 3,000 to 6,000mg a day, the 8,000mg of l-citrulline in this formula makes this a more potent form of citrulline, meaning you may be able to get away with taking smaller doses with similar results in your pump.

Best Citrulline Pills

For anyone on the go, these third-party tested, gluten-free capsules will keep you fueled for your workout even when you don’t have time to mix up a powder drink.

Nutricost L-Citrulline

Nutricost produces a lot of inexpensive supplements and their citrulline pills hit a nice sweet spot between quality and value. According to the manufacturer, the citrulline is non-GMO, it’s gluten-free, it’s made in an FDA-registered facility, and it’s third-party tested to ensure purity and label accuracy. On a per gram basis, this is a pretty inexpensive citrulline product, particularly given the fact that it comes in capsules. This form of citrulline is easy to consume on the go, which is a nice boon for avid travelers. If you’re a vegetarian, you’ll have to look elsewhere though as there is gelatin in these capsules. Additionally, the added fillers to streamline production could be a turn-off for some.

Who Should Buy Nutricost L-Citrulline

• Anyone who prefers easy-to-consume supplements.
• Athletes who travel often with supplements.
• People on a tight budget.

Who Shouldn’t Buy Nutricost L-Citrulline

• The capsules are made from gelatin, so they’re not vegetarian-friendly.
• The capsules also contain magnesium stearate and stearic acid, which help keep the powder from sticking to the machinery in the facility in which it’s made — some consider these "fillers" undesirable.

If you are in the market for a capsulated citrulline supplement, then these are certainly a top-tier consideration, as long as you’re not vegetarian. 

Best Citrulline Malate

If you want a product with a simple ingredient list and a solid dose of malic acid, this pick can be easily absorbed and has the potential to increase your stamina.

Swolverine Citrulline Malate

Naturally found in fruits, malic acid contributes to the sour tastes in apples, and could also play a critical role in the citric acid cycle (or Krebs cycle), allowing for quicker absorption and increased stamina. Whether or not this leads to more reps in the gym is unclear, but citrulline malate could be a promising addition to your supplement stash if you prioritize absorption. This particular supplement contains 5,000mg of citrulline malate per serving, which is a fairly high dosage. With no other ingredients, this supp is about as straightforward as they come.
