| Comment | Costco is selling 600 2000IU vitamin D supplements for less than a fiver. The RDA is 600IU for adults as far as I know. A big portion of it is obviously knowing that you should supplement it, but it isn't terribly expensive. I'd imagine what the NHS could get it for would be lower still and would probably see some returns on it from better wellbeing and health. Plus, a higher dose taken somewhat irregularly is likely still going to have some impact. The RDA of vitamins don't need to be hit bang on every day for you to see the benefits of them. |
