D

Hey Danial! I haven't taken a vit D supplements and haven't used a sunlamp so I can't help you there but just wanted to let you know in case you were vegan that D3 is from an animal source. D2 is from plant sources and I've heard it works well but the needed dosage is just a little more. There's a good post about vitamin d and deficiencies on another site, here's the link:

Hope this helps a little :)

There is a new raw and vegan form of Vitamin D3 called Vitamin Code Raw D3. You can read more about it here:
