What does it do and what is it used for?
Fitholic Professional Citrulline Powder is a dietary supplement designed for active individuals looking to enhance endurance, improve muscle blood flow, and support post-workout recovery.
How does it work?
Citrulline converts into arginine in the body, which helps increase nitric oxide (NO) production. This promotes better blood circulation, more efficient delivery of nutrients and oxygen to the muscles, and reduced fatigue.

What are the benefits?
- Enhances endurance and strength
- Supports faster recovery
- Reduces muscle fatigue
- Increases muscle pump
Who is this product for?
Suitable for strength athletes, runners, cyclists, CrossFit enthusiasts, and anyone seeking better stamina and quicker recovery.
Why choose this product?
Because it is a pure and concentrated formula manufactured in certified facilities (GMP, ISO, HACCP, FDA), with no unnecessary fillers and zero sugar.
How do you choose citrulline and compare the amount per serving?
When choosing citrulline, compare the declared amount of L-citrulline per serving, rather than just the grams of powder or the pack size. Pure L-citrulline and citrulline malate have different compositions, so servings of equal weight do not necessarily provide the same amount of L-citrulline.
Fitholic Professional Citrulline Powder contains citrulline DL-malate with a stated ratio of 1:1. According to the declared product values, one 5 g serving of flavoured powder provides 4575 mg of citrulline malate, including 2515 mg of L-citrulline. This 2515 mg figure is the reference point for comparison with other products.
Citrulline malate and L-citrulline: what is the difference on the label?
L-citrulline is the amino acid. Citrulline malate combines L-citrulline with a malate component. The total amount of this ingredient should therefore not be interpreted as the amount of L-citrulline alone.
| Product or formula | Amount of powder | Amount of L-citrulline |
|---|---|---|
| Fitholic Professional Citrulline Powder | 5 g | 2515 mg according to the declared values |
| A product containing 100% L-citrulline with no other ingredients | 5 g | 5 g, if the composition and purity are confirmed |
| Citrulline malate without a specified L-citrulline content | 5 g | Cannot be determined from the name alone |
The designations 1:1 and 2:1 describe a ratio between the components. For an accurate comparison, check how that ratio is expressed and whether the manufacturer lists L-citrulline separately. In flavoured formulas, some of the serving weight may come from the other ingredients.
What should you check before choosing citrulline?
- The form: pure L-citrulline or citrulline malate.
- The content per serving: distinguish between the grams of finished powder, the amount of citrulline malate, and the amount of L-citrulline.
- The full ingredient list: check the flavourings, sweeteners, and other ingredients.
- The number of servings: compare packs based on the recommended serving size of each product.
- The price: calculate both the cost per serving and the cost per gram of declared L-citrulline.
What does research show about citrulline malate during exercise?
Research findings depend on the type of exercise, the amount used, and the intake protocol. A 2021 meta-analysis found a small average improvement in the total number of repetitions performed to muscular failure during resistance exercise. The included studies used 6–8 g of citrulline malate before exercise. These are amounts used in research, not instructions to increase your serving of Citrulline Powder.
For aerobic endurance, a 2023 meta-analysis found no statistically significant improvement in time to exhaustion or time to complete the exercise task. Findings on repetitions during resistance exercise should therefore not automatically be applied to running, cycling, or other prolonged activities.
These studies examine citrulline under specific conditions and do not constitute a clinical trial of the finished Fitholic Professional Citrulline Powder product. They help you assess the evidence without guaranteeing individual results.
How can you compare citrulline malate prices?
When comparing citrulline prices, use the same basis for comparison. A cheaper pack or a lower price per gram of powder does not necessarily mean a lower cost per gram of L-citrulline.
Citrulline Powder provides 60 servings and a total of 150.9 g of L-citrulline, calculated from the declared 2.515 g per serving.
- Cost per serving = current pack price ÷ 60.
- Cost per 1 g of L-citrulline = current pack price ÷ 150.9.
The first calculation shows the cost of one recommended serving. The second allows you to compare products with different concentrations. When making your final choice, also consider flavour, ingredients, and ease of use.
How should you account for citrulline in a pre-workout supplement?
Check whether your pre-workout formula already contains citrulline or citrulline malate. If both labels list L-citrulline separately, you can add those amounts together to determine your total intake.
If one product lists only grams of citrulline malate, do not add them directly to the grams of pure L-citrulline. Seek clarification about the composition and follow the instructions for both products. Amounts used in research do not replace the intake recommendations on the label.
Which matters more: the ratio or clearly stated content?
For a practical comparison, the most useful information is the clearly stated amount of L-citrulline in the recommended serving. The designation 1:1 or 2:1 alone is not enough to determine which product is suitable for you. For Citrulline Powder, use the declared 2515 mg of L-citrulline per serving and compare the ingredients, price, and intake instructions with the other options.
