Summary
This completed Phase 1 study looked at how vitamin E is absorbed and used in the bodies of normal-weight and obese women, and whether vitamin C helps. Fifty women aged 18 to 40 took part, including some with type 2 diabetes. Researchers gave different doses of vitamin E (by mouth and IV) and vitamin C, then measured levels in blood and urine to understand how body fat affects vitamin E needs.
