Test the combination,
not just a single supplement
Citrulline alone or beetroot alone works. But according to this 9-week study of triathletes, it was their combination that substantially improved aerobic performance. Complete your bundle.
How long until it works
The effect builds gradually — the study results come after a full 9 weeks of regular use.
Exactly what the athletes took
Four groups, the same training plan (6× a week, 9 weeks) — the only difference was the supplement.
When and how much to take
The study tested long-term daily dosing. In practice, a different, more precise timing applies for maximum effect on the day of performance.
What improved — and by how much
Results of the combination group (citrulline + beet root extract) compared with baseline after 9 weeks.
