Nutricost L-Citrulline 1500 mg

Rating breakdown

Evidence for ingredient 7.0/10

L-citrulline has solid evidence for improvements in endurance performance and blood pressure via increased nitric oxide synthesis. Effective study doses are often 3–6 g, so 1500 mg is on the lower end — effects at lower doses are less well documented.

Value for money 8.0/10

About €0.17 per day for 90 servings of 1500 mg is affordable. To reach higher doses, multiple capsules would be needed, increasing cost.

Product quality 7.0/10

Simple, clean formulation without unnecessary additives. Typical Nutricost: functional and no-frills.

Label honesty 7.0/10

Clear disclosure of dose and ingredient without exaggerated performance claims. Typical US style, but not misleading.

Third-party testing 6.0/10

Nutricost references third-party testing and GMP production. Without a specific certification (e.g. NSF Sport), verification is less rigorous than premium brands.

Product Description

Nutricost L-Citrulline delivers 1500 mg L-citrulline per capsule — a convenient capsule format for those who prefer not to use powder. L-citrulline is an amino acid converted in the body to L-arginine, thereby increasing nitric oxide production. This can positively affect training performance, endurance, and blood pressure.

What We Like

Very affordable entry price for L-citrulline
Capsule form — more convenient than powder on the go
Clean formulation without unnecessary additives
Third-party testing and GMP production

What We’re Missing

1500 mg is at the lower end for clinically relevant effects (studies often use 3–6 g)
Not available in Germany — US import required
No specific certification (no NSF Sport etc.)

Usage Recommendation

Take 1–2 capsules daily, ideally 30–60 minutes before training.
