Abstract:
Conflicting reports of the effects of beta-carotene supplementation on serum alpha-tocopherol concentration led us to evaluated serum alpha-tocopherol in subjects with and without beta-carotene (30 mg/day) supplementation for up to 2 years duration in an ongoing chemoprevention trial. No adverse effect has been observed at any of the time periods examined.
