There is so much in the media about the virtues of adding Vitamin D into your diet, certainly with all the Covid virus about. But is there any value to it? Wouldn’t a 20 minutes daily walk suffice?

The cost of taking these supplements can build up, as we are always told don’t buy the cheap stuff full of fillers etc. Other than Covid what other benefits are there to taking Vitamin D, and do any of you take it and notice a difference?
