9 tips for winter vitamin D!

Until at least April, it is hard to get enough vitamin D, so here are some tips on how to supplement:

1.The most effective vitamin source is D3. D2 (often prescribed) will do, but isn’t as effective*.

2.Supplements of D3 are absorbed just as easily into the body as from dietary sources or from the sun*.

3.Cod liver oil contains lots of vitamin D, but take care not to over suplement due to high vitamin A levels*.

4.The average person can safely supplement with 5000iu´s*.

5.10,000 iU´s is the average persons maximum daily dose and shouldnt be exceeded*.

6.A study found supplementing with 4000iU´s of vitamin D was enough to bring a significant majority of adults out of vitamin D deficiency**.

7.Sun beds provide sufficient UVB radiation (required for vitamin D production in skin) even in short sessions*.

8.Not all D3 supplements are vegetarian friendly.

9.A vitamin D supplement is around 65 times cheaper than a boring 6 day budget holiday to Majorca and lasts around 2 times longer!*** That’s roughly 130 times more cost effective, and no drinking their dodgey water what don’t taste like what it oughta!
