I tried a 1000 IU vitamin D pills to no avail. Bumped it up to 5000 IU and still saw very marginal bumps in my blood tests I think I might try daily 10000IU after showing my doctor how little it's moving the needle for me

I was put on prescription vitamin D2 50000 IU and it caused a bunch of side effects for me including heart palpitations for over a week and then a paradoxical reaction to magnesium causing them to be even more intense. Proceed with caution and listen to your body. Doctors were accusing every other thing than accepting whatever it did to my calcium / other electrolytes bothered my heart.

Interesting, my levels have always been chronically low and I feel no effects from daily 5000IU

It's expensive in the US because one company has exclusive sales here (patent protection?), but you could try calcefidiol, weekly dose and is supposed to get levels up rapidly. Apparently it's the common form to take in Spain, and it's further down the metabolic pathway vs cholecalciferol. (I take but still have to get levels checked)

thank you, will have to check this out

Unfortunately this is a common error people make, many vitamins and other supplements are absorbed better when taken with food, even if that seems counterintuitive at first.

Another thing I am curious about is time of day too -- I was told vitamin D/Multivitamins were better taken in the morning with food.

While I’d love to just go for a walk outside, the allergen exposure of the outdoors is too high most of the time. This elements any mental health benefits a walk in a forest might otherwise give.

Allergy shots work very well.

Privileged comment. Walks in a controlled greenhouse without allergenic pollinators also work, but the poor can't easily access either in the US.

It really depends. Other things like iron is best taken fasted (and paired with Vitamin C). Coffee also blocks iron absorption, so many people supplement at nighttime. Also things like Zinc and Copper both compete with each other for absorption, so best to avoid taking them at the same time.

If you're optimizing your supplement stack, really gotta research each one individually (and how each impact the absorption of the others)

Most vitamins are a waste of time and money, some are even harmful[1], but there are a lot of people with D deficiency, especially in winter[2]. 1 https://www.mdpi.com/2072-6643/17/17/2744#:~:text=highest%20... 2 https://www.abs.gov.au/articles/vitamin-d#edit-group-image--...

How do you feel about vaccines and Tylenol?

Uncalled for. GP is pointing out that the fact the human body can produce Vitamin D means it is not a vitamin.

vi·ta·min /ˈvīdəmən/ noun any of a group of organic compounds which are essential for normal growth and nutrition and are required in small quantities in the diet because they cannot be synthesized by the body.

While I find your comment enjoyably pithy, in the case of vitamin D, many humans are currently living at latitudes which they are not suited to (skin being too dark to generate enough vitamin D given the insolation), and eating diets which do not provide them with sufficient amounts of it (the carnivore diets of Inuits and similar groups being a good contrast).

Amusing how thanks to the war on cholesterol the UK unravelled a lot of egg eating habits - a natural source of vitamin D. The UK also consumed a lot more liver than it does today I imagine...

Are they that unpopular? Seem like a staple of an English Breakfast.

"Winnipeg, Manitoba" ... "only need 15 minutes of sunshine per day to get your recommended dose of Vitamin D" That doesn't apply to you most of the time, unfortunately. Vitamin D is the result of UVB exposure. For significant portions of the year, you don't get very much [1], compare with, say, [2] Orlando Florida in the US. 10-15 minutes is for a UV index of 7 [3], so that's only 4-6 months out of the year for you.…

I grew up on the Canadian praries. -10C is basically shorts weather. edit: seriously though, anything warmer than -10C you'll definitely see kids in shorts. I go skiing in shorts every year.

Wear a g-string if you want. It doesn't make the sunlight any brighter in winter.

I wonder if adding zinc on top of this would do.

Would do...? Zinc taken the first day of symptoms may reduce the duration of a cold by a day on average. It's probably useful, but not certain.

Be sure to take zinc with meals, or your stomach may hate you.
