Halal-specific guidance

Soy isoflavones are usually easier to verify, but check the exact product label. Confirm there are no animal-derived additives (rare in standard formulations).

How to verify a halal certificate

  1. Visit JAKIM's the official JAKIM Halal Status Check page
  2. Search for the manufacturer or brand's halal certificate number
  3. Confirm the certificate date is still valid (halal certs renew every 1-2 years)
  4. For imported products, check the country-of-origin halal certificate (e.g. JAKIM equivalent in the import country)
  5. If in doubt, contact the manufacturer directly for documentation
