Healthspan Elite 4,000iu Vitamin D3

Frequently asked questions

Is 4,000 IU a safe daily dose?

4,000 IU sits at the EU upper safe intake for daily vitamin D3 in adults. It's at the higher end of OTC retail strengths and is typically used by people supplementing year-round or correcting low levels.

Where can I buy Healthspan Elite 4,000 IU D3?

Amazon UK and Healthspan direct both list at £24.99 — pick whichever channel you prefer. Check the pack size on the live listings before comparing value.

How does this differ from the 1,000 IU variant?

Same brand, same Informed Sport-tested status, four times the per-tablet dose. Some users take the 4,000 IU alternate-day; check the on-pack guidance.

Why bother with Informed Sport on a D3?

Tested athletes often want banned-substance screening across every supplement they take, including baseline vitamins — contamination risk can sit anywhere in the supply chain.

When should I take vitamin D3?

D3 is fat-soluble and absorbs better with a meal containing fat. Time of day matters less than co-ingestion with fat.
