Sure, and that's great, but what about the scenarios in which I cannot walk to the park (during 600+ AQI wildfires, as an example), is the reason I'd like the data on supplementation.
- undersuit 6y agoYou can buy or make a SAD/Sun Lamp.
- galenlynch 6y agoMost 'sun lamps' do not emit UVB, which is required for your body to make vitamin D.
- undersuit 6y agoThen don't buy those if your looking for that feature?
- xdavidliu 6y agoyou're missing the point; he's saying that sun lamps don't have the same effect as the sun. This isn't just a "feature" that some lamps have and others don't; it's a crucial missing ingredient that results in the sun lamps you are suggesting simply _not working_.
- undersuit 6y agoNo, I'm not. There are UVB generating light sources and they also fall under the SAD/Sun lamp definition.
- UrSuchAGenius 6y agoWhat about buying vitamin D3 and ending this stupid discussion?
- azinman2 6y agoBecause the question is whether or not artificial supplements yield the same results as sunlight.
- bird_monster 6y agoSure, and that's great, but I'm asking about the efficacy of a supplement
- DanBC 6y agoYou're never going to get sensible dietary advice on HN. Get sun. If you can't get sun you should eat a variety of food that contains vitamin D. If you can't do that, you should take a supplement. Take the supplement at the same time as you eat a meal, preferably a meal that has some fat. Here's the advice for England: https://www.nhs.uk/live-well/healthy-body/how-to-get-vitamin-d-from-sunlight/ https://www.nhs.uk/live-well/healthy-body/how-to-get-vitamin... https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/ https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-...
- gerdesj 6y agoFreely available advice from the UK's NHS would seem to be a good idea. We fund the NHS mostly out of taxation, so advice provided there has to be as close to non partisan as is reasonably possible. I personally don't give a shit if you are a foreigner. If the NHS website can provide good advice and help someone - anyone, then my tax squids are being put to good use. There are bound to be other good sources of health related advice around the place but why not start with the NHS and work out from there?
- gridlockd 6y agoIf you pay close attention, health authorities always play it safe, for example by saying "there's not enough evidence". That's why they didn't recommend masks in the beginning. Then, if some sort of expert consensus comes up, the authorities adopt that. When that consensus is challenged by new evidence, authorities are slow to change, because that would be implicit admission that they were giving the wrong advice, which is not something that the human egos involved there can easily stomach. A good example for this is the food pyramid[1]. It was never supported by good evidence, it was adopted through expert consensus (one might also call it lobbying), and it was later removed from the guidelines. You can still see posters of it hanging in doctor's offices, of course.
