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
- chelated mineral capsule or powder
- 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.

Product form & quality guidelines
When sourcing Zinc, verify the label for:
- Standardized Extract: Confirm active content percentages on the supplement facts panel (e.g. standardized to specific marker compounds) rather than simple raw herb weights.
- Third-Party Testing: Look for independent purity labels (USP, NSF, ConsumerLab, or Eurofins) to ensure the product is free from heavy metals, solvents, and contaminants.
- Form Bioavailability: Ensure the form matches evidence-supported configurations (e.g. chelated bisglycinate/glycinate for magnesium, micronized monohydrate for creatine) for optimal onset and digestion tolerance.
