Vitamin D 3 shown to be twice as effective as D2

A new study (from the University of Surrey) is hitting the headlines showing that vitamin D 3 is twice as effective at raising vitamin D status than the D2 form.

Vitamin D 3Vitamin D Government Guidelines

The current guidelines state that everyone in the UK should consider supplementing with at least 400iu of vitamin D (although in many cases higher doses are best for optimum nutrition). Many guidelines around the world (including the UK) don’t dictate which form of vitamin D they recommend or incorrectly state that D2 supplements are equal to D3. Experts now believe that this new study could change official guidelines to recommend vitamin D 3 specifically.

Lead author Dr Laura Tripkovic from the University of Surrey, said: “The importance of vitamin D in our bodies is not to be underestimated, but living in the UK it is very difficult to get sufficient levels of it from its natural source, the sun, so we know it has to be supplemented through our diet. “

Those who consume D3 through … D3 containing supplements are twice as more likely to raise their vitamin D status than when consuming vitamin D2…containing supplements, helping to improve their long term health.
