Tag: Vitamin e for skin

One international unit (IU) of natural vitamin E is equivalent to 0.67 mg, while one IU of the synthetic form is 0.45 mg, creating significant confusion for consumers wondering how much IU should be in vitamin E oil. The ideal concentration largely depends on whether it's for topical application or oral consumption.

The tolerable upper intake level (UL) for supplemental vitamin E in adults is 1,000 mg daily, which can translate to 1,100 to 1,500 IU depending on the form. With some topical products boasting incredibly high IU counts, it is natural to question: is higher IU in vitamin E oil better or is it just a marketing tactic?
