Blood pressure: what the evidence supports and L-Citrulline
Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.

Blood pressure: what the evidence supports
14 graded interventions for blood pressure, ranked by strength of evidence.
Grade B14 graded outcomesrevised Jul 10, 2026
Assembled by the app from other entries in this library. It adds no evidence of its own — follow the links to the entries it draws on.
Compound or practice
L-Citrulline
The arginine route that actually absorbs — a legitimate pump-and-reps pre-workout with modest blood-pressure benefit.
Grade B3 graded outcomesrevised Jul 10, 2026
A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.
Graded in both
Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.
No outcome has the same name in both entries. They may still overlap under different wording — read the two lists below.
