You know watermelon is a tasty summertime treat, but did you know it’s also one of nature’s best sources of citrulline? Unfortunately you’d have to eat several pounds of watermelon every day to reap the benefits. Just what is citrulline though? It's bursting onto the fitness scene in a big way, helping people of all ages break through the boundaries of personal health and fitness. L-citrulline is active in both the Krebs cycle and the Urea cycle of metabolism, which means it promotes energy production to fuel activity while simultaneously helping to rid the body of metabolic waste products, helping to promote muscle recovery after exercise1. The addition of malate, a form of malic acid, further bolsters the bioavailability of L-citrulline.

L-citrulline is an amino acid precursor to—and more efficiently absorbed by the body than—arginine which in turn produces nitric oxide. Nitric oxide works to deliver oxygen and other nutrients throughout the body to feed muscles and tissues. This is especially beneficial during high-intensity exercise, and may also help maintain blood pressure already within the normal range2, support men’s sexual health2, and encourage active aging by promoting cardiometabolic health in older adults3.

  1. What are the benefits of taking Swanson L-Citrulline Malate Complex?
    Swanson L-Citrulline Malate Complex provides 750 mg of L-citrulline malate per capsule to support healthy nitric oxide production, exercise performance and muscle function. L-citrulline is an amino acid that the body converts to L-arginine, helping support healthy blood flow, while malate (malic acid) plays a role in normal cellular energy production. Together, these ingredients help support endurance, workout performance and overall vitality as part of an active lifestyle.
  2. How does L-citrulline malate support nitric oxide production?
    L-citrulline is converted by the body into L-arginine, which serves as a precursor for the production of nitric oxide (NO). Nitric oxide helps support the healthy relaxation of blood vessels, promoting healthy circulation and blood flow. Swanson L-Citrulline Malate Complex provides nutritional support for the body's natural nitric oxide pathway to complement exercise and cardiovascular wellness.
  3. Why is malate combined with L-citrulline?
    Malate (malic acid) is a naturally occurring compound involved in the body's normal energy-producing processes. When combined with L-citrulline, malate complements the formula by supporting cellular energy metabolism, while L-citrulline supports healthy nitric oxide production and circulation. This combination is popular among active individuals looking to support endurance, performance and post-exercise recovery.
  4. How does L-citrulline malate support energy production?
    L-Citrulline malate supports healthy energy production through the complementary actions of its two components. Malate participates in the body's normal energy-producing pathways, helping cells efficiently generate energy from nutrients. At the same time, L-citrulline supports healthy nitric oxide production and circulation, helping deliver oxygen and nutrients to working muscles during exercise. Swanson L-Citrulline Malate Complex provides 750 mg of L-citrulline malate per capsule to support energy metabolism and an active lifestyle.
  5. Why choose Swanson L-Citrulline Malate Complex instead of L-citrulline alone?
    Swanson L-Citrulline Malate Complex combines L-citrulline with malate to provide complementary support for healthy nitric oxide production, energy metabolism and exercise performance. This combination supports healthy circulation, muscle function and endurance, making it an excellent choice for individuals seeking nutritional support for an active lifestyle and overall wellness.
  6. Is Swanson L-Citrulline Malate Complex suitable for special dietary needs?
    Yes. Swanson L-Citrulline Malate Complex is non-GMO, making it a great choice for individuals who prefer supplements made without genetically modified ingredients. Each capsule provides 750 mg of L-citrulline malate to support healthy nitric oxide production, circulation, exercise performance and energy metabolism as part of an active lifestyle. As always, review the complete Supplement Facts and ingredient list to ensure the product meets your individual dietary needs, preferences and any ingredient sensitivities.
