No vitamin D generated without sunshine ?

...; you cannot buy tablets with the required levels to restore deficiency - they are prescription-only. Not in the UK anyway,

 

...

You may be able to buy vitamin D over the counter at high concentrations as a rat poison.

I'm not suggesting that as a source- just something to think about.

Had a look. Yes, interesting use of it.

Interesting, and also a good reason to check that you have a shortage before taking serious measures to increase your intake.

Indeed and would always suggest that. I think I read you have to be more careful with D₂ than D₃ wrt to overdosing.

yes. no need D2, even D3 which is too strong and too much. D1 is quite enough for normal people.

Vitamin D or D₁ is the other two mixed together; this is the original compound but it was discovered that it is two compounds. D₃ is the recommended one because it's utilised more easily by the body; it requires fewer steps, amongst several other good reasons
