📑Citrulline Reference Tables
| Workout type | Low range | Middle target | Best use |
|---|---|---|---|
| Hypertrophy / pump lifting | 6 g | 7 g | Pre-workout pump and volume sessions |
| Strength / power lifting | 5 g | 6 g | Heavy sets where GI comfort matters |
| Mixed conditioning | 5 g | 6 g | Circuits, CrossFit-style sessions, and mixed work |
| Endurance cardio | 4 g | 5 g | Longer steady sessions or races |
| Intervals / repeated sprints | 5 g | 6 g | Repeated high-output bouts |
| Rest-day vascular support | 3 g | 4 g | Non-training day planning only |
| Label ratio | Citrulline share | Product for 6 g L-cit | Rule used |
|---|---|---|---|
| Pure L-citrulline | 100% | 6 g | Product grams equal L-citrulline grams |
| Citrulline malate 2:1 | 66.7% | 9 g | L-citrulline target divided by 0.667 |
| Citrulline malate 1:1 | 50% | 12 g | L-citrulline target divided by 0.5 |
| Citrulline malate 3:1 | 75% | 8 g | L-citrulline target divided by 0.75 |
| Custom label | Input percent | Varies | L-citrulline target divided by custom share |
| Timing choice | Window used | Serving plan | Practical note |
|---|---|---|---|
| Pre-workout | 30-60 min before | Usually one serving | Most common setup for lifting sessions |
| Intra-workout | Start to mid-session | Smaller serving during training | Useful when pre-workout dose feels heavy |
| Split pre + intra | 30-45 min before plus intra | Divide product across two servings | Often better for larger malate doses |
| Daily non-training | Any consistent time | Split with meals if needed | Not a performance-timing claim |
| Late or short notice | 15-30 min before | Use a conservative dose | May not feel the same as full lead time |
| Step | Formula | Input | Output |
|---|---|---|---|
| L-citrulline target | Workout midpoint x tolerance factor | Workout and tolerance | Practical equivalent grams |
| Malate product dose | L-cit target / citrulline share | Malate ratio | Total product grams |
| Per-serving dose | Product dose / servings | Servings per day | Grams per serving |
| Per-kg dose | L-cit target / body weight kg | Weight and target | mg/kg L-citrulline |
| Current comparison | Current L-cit equivalent / target | Current dose and product type | Below, in range, or high |
💡Tips
Citrulline supplements is frequent used by individuals who wishes to increase there blood flow, and citrulline is a common ingredient in preworkout supplements. Supplementation form of citrulline are not the same. There are two common forms: L-citrulline and citrulline malate.
Each of these forms contain the same amount of active citrulline per gram of supplement. Citrulline malate supplement also contain a partner molecule, malic acid. To provide the same amount of active citrulline as L-citrulline, a person must take a higher dose of citrulline malate.
Find the Right Citrulline Dose
To determine the correct amount of citrulline supplement that a person should take, a dosage calculator can be use. A dosage calculator will account for the form of citrulline that are being taken and the body weight of the individual who will take the supplement. To calculate the proper dosage of citrulline supplement that an individual should take, the individual must first enter the supplement’s form into a dosage calculator.
Additionally, the person taking the supplement must also enter the body weight. If the supplement that is being taken contains citrulline malate, the dosage calculator can also use the ratio of citrulline to citrulline malate that is published on the supplement label to calculate the amount of active citrulline that the individual will recieve. By taking these steps, the individual ensure that they will not consume too little citrulline supplement to experience its benefit.
The dosage calculator also asks for information regarding the type of workout that will be performed and the individual’s tolerance to citrulline doses. An individual who performs mainly hypertrophy workouts may require a higher dosage of citrulline then an individual who performs mainly endurance workouts or who wishes to avoid feeling gastrointestinal discomfort. The dosage calculator provide an individual with information regarding the equivalent amount of L-citrulline that the supplement that is being taken will provide, the amount of citrulline malate that is required to provide such a dose of L-citrulline, and the timing with which the supplement should be taken relative to the training session.
The dosage calculator also provides information regarding the amount of citrulline supplement that should be taken per kilogram of the individual’s body weight. This information can be helpful in the event that the individual’s body weight change over time. Additionally, the calculator makes it possible for an individual to compare the dose of citrulline that is being taken to the target dose that is recommended for the individual’s body.
While the dosage calculator ensures that the individual who intends to take the supplement performs the arithmetic calculation correctly, the dosage calculator does not account for how citrulline may specifically react within each individual’s body. Factors outside of the body can also influence how effective citrulline supplements perform their intended bodily functions. For instance, an individual’s sleep cycle, their amount of sodium consumed during the day, and the time of day of their last meal can all have an impact upon the effectiveness of the supplement containing citrulline.
Some individuals may find that they are able to more effective utilize citrulline supplements if they split their dose into two separate amounts throughout the day. These separate doses may help to reduce the amount of pressure that the supplement can place upon the individual’s stomach. Supplementation with citrulline increase the amount of arginine and nitric oxide within an individual’s body.
Citrulline is able to effectively perform this function because it avoids the digestive loss that can occur for arginine supplements. To ensure that citrulline supplements are effective, an individual must consume enough citrulline to allow the molecule to reach their bloodstream. To do this, the dosage calculator ensures that the amount of citrulline supplement that is scooped is the same as the amount required by research studies as effective supplement for nitrates.
