Yes taking vitamin D tablets is just like eating burgers obviously.
People will need different amounts depending on their circumstances. So for example BAME, elderly and overweight/obese people are much more likely to be vitamin D deficient than say a fit runner. I’m not saying that I’m a particularly fit runner at the moment but clearly other people will be more vitamin D deficient than me.
When I posted about vitamin D deficiency I thought that would be pretty uncontroversial on this forum, it’s not exactly Brexit after all. But obviously I was wrong!
