That's a very coloured centric viewpoint. The fact is that the majority of people of planet earth can go out in the sunshine at the right time of day and get 80-90% the vitamin D they need and get the rest from a balanced diet.

Majority? Are you sure about that?

I just want to say the b complexes are indeed super important, but recent studies indicate a potential link between overly high dosage and some types of cancers, particularly in men. So be wary of overdoing it with those 3000% dv supplements.

I threw out some vitamins and energy drinks after reading about this. https://www.theatlantic.com/health/archive/2017/08/b12-energ...

What if the increase in lung cancer was caused by more breathes being taken. It would be funny if both the “energy/metabolism” crowd and the “cancer” risk proponents were correct.

Throwing in my two cents. I used to suffer from seasonal mood swings, since taking a daily multivitamin this has been the best winter of my life.

I have very severe anxiety attacks which I finally have under control partly through vitamin B and fish oil supplements.

Consider replacing the fish oil with algae-derived omega 3. It has all the benefits with none of the downsides (toxic metals, fishy burps, environmental cost). Fish get their omega 3 from algae anyway so why not go straight to the source?

One point of caution: Anyone who takes Vitamin D supplement, make sure you take 25-Hydroxy (Calcifediol) and not the active form - 1,25 dihydroxy (Calcitriol). Active form has severe side effects and is not supposed to be used for supplementation unless in you have kidney problem which prevent metabolizing 25-Hydroxy.

I thought all D2 and D3 supplements would be ergocalciferol and cholecalciferol, respectively, while calcitriol is what gets tested to assess blood levels. Do any supplements actually contain calcitriol?

Medical system in India is a mess of kickbacks. A Doctor gave my cousin a prescription of Calcitriol because it was much more expensive. Led to major side effects which went away as soon as it was stopped.

Supplements don't have it. However that warning was for someone who goes out of way to acquire Calcitriol.

Steve Gibson has talked about this issue in the past: https://www.grc.com/health/vitamin-d.htm (And please, yes we get it you are a smart ass, don't link to the page that you are going to. The horse has been beaten to death.)

Now I'm curious as to what page you're referring to.

Because of impaired kidney function, I get my vitamin D levels monitored every month. Yes supplements can take 2-3 months to increase the levels. The sun actually works pretty good if you can stay outside 15 minutes in noon sun. But that's difficult in the winter months.

I've read varying reports of how much sun you need to generate a day's supply of vitamin D, but rarely do they mention how much skin needs to be exposed. Face only? Face and arms? Entire upper body? Entire body? Is there some online resource for this with time of year and latitude corrections? I imagine there's quite a difference between vitamin D production in noon sun in Fairbanks Alaska versus Miami Florida.

For it, my face and arms are exposed. I walk in the bay area sun for 15 minutes after lunch. Doing this regularly over a month or two will boost my numbers from the mid 20s to mid 30s.

Same here, D3 with Magnesium and Calcium since they are co-factors. Should take K2, too.

You probably won‘t believe it when I say that my immune system and energy levels are better than any winter before, but thats how it is.

I wonder if light therapy is actually just indirect vitamin D therapy.

A couple years after I moved to Seattle I started noticing some odd aches and pains. After a coworker had similar issues, I went to the doctor, and they tested my Vitamin D levels. They were ridiculously low. They had me on a high initial dose, and than taking supplements ever since. I've heard the same story from tons of neighbors. Nowadays it's one of my first suggestions for new transplants. It's made a marked difference (along with a sunlamp).

> along with a sunlamp

a regular sunlamp? They are UV-A and don't help with Vit D at all

You need a UV-B one which doesn't tan - https://www.amazon.co.uk/dp/B004NOPC9S/
