SCIENTIFIC STUDIES

We have summarised some of the most interesting scientific studies on L-citrulline.

It is important to note that a decrease between 5 and 12 mmHg of systolic blood pressure and between 5 and 6 mmHg of diastolic blood pressure is associated with a 14–38% risk reduction in stroke and a 21% risk reduction of death due to coronary disease.

Study 1

Study type: 

Randomised controlled trial

Participants:

12 young adults with normal blood pressure

Dose: 

3g of citrulline tablets per day

Duration:

1 week

Results:

Citrulline consumption was associated with a 6% reduction in systolic blood pressure and a 14% reduction in diastolic blood pressure.

Year:

2016

Study 2

Study type: 

Randomised controlled trial

Participants:

41 obese postmenopausal women

Duration:

8 weeks

Results:

L-citrulline supplementation was associated with significant reductions in blood pressure.

Year:

2015

Study 3

Study type: 

Randomised controlled trial

Dose:

3g per day

Participants:

Heart failure patients

Duration:

2 months

Results:

L-citrulline supplementation was associated with significant reductions in systolic and diastolic arterial blood pressure.

Year:

2015

Link:

https://doi.org/10.1139/apnm-2015-0465  

Study 4

Study type: 

Systematic review

Intervention under study:

Oral supplementation with L-citrulline

Studies reviewed:

8 randomised controlled trials

Results:

The results suggest that L-citrulline supplementation may reduce systolic blood pressure (-4 mmHg). A significant reduction in diastolic blood pressure was observed only in the studies that used doses greater than 6 g of L-citrulline per day.

Study 1

Study type: 

Randomised controlled trial

Dose:

6 g L-citrulline-malate 2 h prior exercise

Participants:

17 male pre-professional cyclists

Duration:

Acute (before and after a 137-km cycling race)

Results:

After the cycling race, growth hormone levels were higher among participants taking L-citrulline malate than among participants in the control group. L-citrulline supplementation was also associated with higher levels of arginine-derived metabolites such as nitrite, creatinine, ornithine and urea.

Year:

2010

https://doi.org/10.1007/s00421-010-1509-4 

Study 2

Study type: 

Randomised placebo-controlled crossover trial

Dose:

2.4g of L-citrulline for 7 days and 2.4 g of L-citrulline 1h before a 4-km cycling time trial on day 8.

Participants:

22 athletically-trained males

Duration:

8 days

Results:

Compared to the placebo, L-citrulline supplementation was associated with a 1.5% reduction in the time taken to complete a 4-km cycling time trial. It was also associated with significant increases in plasma L-arginine levels.

Year:

2016

Study 3

Study type: 

Systematic review

Intervention under study:

L-citrulline supplementation before exercise

Studies reviewed:

13 studies comprising 206 participants

Results:

The results show a correlation between citrulline supplements and significant reductions in the rate of perceived exhaustion during physical activity and muscle soreness 24h and 48h after exercise.

The results suggest that athletes may benefit from ingesting either L-citrulline alone or 1h before exercise to resist fatigue or relieve muscle soreness.

The Beetroot capsules are lovely and even though the effects have not been staggeringly significant at the moment I can feel the difference in my pump when I work out and because I am a medium build my veins are popping out a lot more.

Frequently Asked Questions

  • Are there any side effects?

    Scientific research has shown that L-citrulline is well-tolerated up to 15g/day. In rare cases, amino acids such as L-citrulline may cause gastrointestinal upset. If this occurs, it is important to significantly lower the dosage.
