Why it's used

Health notes

TBHQ is an FDA-approved food additive. The FDA has established limits for its use in food, and it is generally recognized as safe (GRAS) when used within these limits. Studies in animals have shown potential health effects at very high doses, but these are not considered relevant to typical human consumption. JECFA has evaluated TBHQ and established an acceptable daily intake.
