Strongest recorded design is a randomized controlled trial, drawn from 2 recorded studies, 2 in people.
How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials

Dosing
- Common form
- standardized extract
- No standardized dose
- Our source data records the usual product form for this ingredient but no studied dose. Preparations differ widely, so follow the standardization on the product you actually have and speak to a clinician before starting.
Mechanisms & biological pathways
Preclinical mechanism details from scientific profiles; these represent plausible pathways but do not guarantee clinical efficacy in humans.
- Vascular Function Support
- Cardiac Contractility Signaling
- Endothelial Signaling Modulation
