Product Description

Citrulline malate is a combination of two compounds: citrulline and malic acid. It can be produced by the body itself or obtained from food. The combination of citrulline and malic acid provides the benefit of enhanced muscle function and helps reduce the accumulation of ammonia in skeletal muscle, thereby reducing muscle fatigue and prolonging exercise time, and is therefore widely used as a performance-enhancing supplement.

Function and Effects

★ Enhanced Nitric Oxide Production:

L-Citrulline DL-Malate plays a crucial role in the urea cycle, leading to the production of L-arginine, a precursor for nitric oxide (NO) synthesis. Elevated NO levels promote vasodilation, improving blood flow and cardiovascular health.

★ Improved Exercise Performance:

As a performance-enhancing supplement, L-Citrulline DL-Malate aids in reducing muscle fatigue and enhancing endurance during physical activities. It contributes to the elimination of ammonia, a byproduct of exercise, thereby delaying the onset of fatigue.

★ Ammonia Detoxification:

L-Citrulline DL-Malate facilitates the removal of ammonia from the body, a process vital for preventing cellular toxicity. Ammonia buildup can occur during intense physical exertion, and the supplement assists in maintaining optimal pH levels in muscle tissues.

★ Support for Muscle Protein Synthesis:

The amino acid L-citrulline, derived from L-Citrulline DL-Malate, supports the synthesis of proteins in muscle tissues. This is particularly beneficial for individuals engaged in resistance training or seeking muscle development.

★ Enhanced Energy Metabolism:

L-Citrulline DL-Malate participates in the Krebs cycle, promoting efficient energy metabolism. By enhancing ATP production, it contributes to sustained energy levels, making it beneficial for both athletes and individuals seeking improved vitality.

Application Fields

★ Sports Nutrition:

L-Citrulline DL-Malate is widely utilized in sports supplements to enhance exercise performance and reduce muscle fatigue. Athletes and fitness enthusiasts incorporate it into pre-workout formulations for improved endurance.

★ Cardiovascular Health:

Due to its role in promoting nitric oxide synthesis, L-Citrulline DL-Malate finds application in cardiovascular health supplements. It contributes to vasodilation, which can help manage blood pressure and support overall heart function.

 Bodybuilding and Muscle Development:

In the realm of bodybuilding, L-Citrulline DL-Malate is valued for its potential to support muscle protein synthesis and reduce muscle soreness. It is often included in formulations targeting muscle growth and recovery.

 General Health and Wellness:

Beyond specific athletic or medical applications, L-Citrulline DL-Malate is employed in general health and wellness supplements. Its ability to support energy metabolism and overall vitality makes it a versatile ingredient for those seeking a comprehensive health boost.

    Q: What are the key differences between L-Citrulline DL-Malate 1:1 and 2:1 formulations, and how does the choice of ratio impact their physiological effects, solubility, taste, applications, and cost considerations?


    Molar Ratio Distinctions:

    1:1: Equal molecular proportions of L-Citrulline and Malate.

    2:1: Two moles of L-Citrulline for every one mole of Malate.

    Physiological Effects:

    1:1: Balanced composition suitable for general health.

    2:1: Higher L-Citrulline concentration may lead to more pronounced vasodilation, favored for enhanced exercise performance.

    Solubility and Taste:

    1:1 and 2:1: Influenced by manufacturing processes and additives. Higher L-Citrulline concentration in 2:1 may impact taste and solubility.


    1:1: Versatile for overall health formulations.

    2:1: Preferred in sports nutrition for nitric oxide production and exercise benefits.

    Cost Considerations:

    1:1: Generally more cost-effective.

    2:1: Cost should align with formulation goals and market demand.

    Q:Which is better, citrulline or citrulline malate?

    A:Opinions on this topic are divided. Some people prefer pure citrulline supplements, known as L-citrulline, because these supplements provide 100% of the active ingredients they want to supplement. Others prefer citrulline malate supplements because the malic acid in the formula is purported to enhance the biological effects of citrulline.

    Both have their own advantages, but citrulline malate is superior. The key difference is its ability to increase muscle pumping and athletic performance, which means more times, effective time in the gym, and better results. Another advantage of using citrulline malate is that you don’t have to take it, and L-citrulline is most effective after a week of stable use. This means you can take it before your workout and experience the performance benefits immediately.

    If you can’t accept a very sour taste, or the gastrointestinal function is not good, you can choose pure citrulline, which is relatively milder.
