Safety & Cautions

High caution compound with narrow therapeutic window in preclinical literature. Do not infer supplement safety; avoid pregnancy, liver/kidney disease, and unsupervised use.

High caution

Caution level: High. Multiple caution categories apply, or the record uses avoid/contraindication language.

  • Liver-SensitiveLiver-related caution language appears in the profile.

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

How Celastrol Works
