At Keter Wellness, safety and potency are not optional. Every batch of our Mucuna pruriens is subject to rigorous third-party testing to ensure it meets our strict specifications for purity and efficacy. We believe you have the right to know exactly what is in your bottle.

We partner with ISO-accredited independent laboratories to verify:

• Identity: Confirming the botanical is 100% Mucuna pruriens (Velvet Bean).
• Potency: Verifying the standardized L-DOPA content (e.g., 20%+) matches the label claims.
• Purity: Screening for heavy metals (Lead, Arsenic, Cadmium, Mercury) to ensure they are well below safety limits.
• Microbials: Testing for yeast, mold, E. coli, and Salmonella.

Transparency means proof. Below you can find the lab reports for our recent production lots.
