Why is the default vitamin E intake set at 15mg daily?

Is this not a highly excessive intake?

According to the NHS (https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-e/) the amount needed for males is 4mg daily for males, not 15mg. Perhaps the oral bioavailability of Alpha-Tocopherol being low so high oral dose is needed to compensate? I can not find any answers looking through research myself.

Hi HarryD,

The default nutrient targets in Cronometer are based on the Recommended Dietary Allowances and Adequate Intake values in the Dietary Reference Intakes used in Canada and the USA. Here's a link to the summary tables: https://www.nap.edu/read/25353/chapter/28#567

You can customize your target if you would like to use the NHS values. Click on the target in your diary. Then, click the toggle to use custom values and enter those values in the boxes above:
