Why not just go on a daily walk to get your Vitamin D?
- cameron_b 3y agoThat's always a great option, but weather and seasonal differences can keep large portions of the world from achieving healthy levels of Vitamin D.
- jszymborski 3y agoIt's dark out for most of the day in some climates. In others, it's dark out for much of the year.
- goda90 3y agoNot just the darkness, but the necessary UV wavelengths literally can't reach you in the middle of that day without a cloud in the sky for some parts of the year at higher latitudes.
- goda90 3y agoAt higher latitudes you can only get vitamin D from the sun for a few months of the year. In winter, the sun is too low in the sky, and the UV wavelengths needed to produce the vitamin D is entirely blocked by the atmosphere(though unfortunately the UV for sunburns is not). This is a method of "storing" summer vitamin D for winter consumption.
- n4r9 3y agoFor the UK: https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/ https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-... > During the autumn and winter, you need to get vitamin D from your diet because the sun is not strong enough for the body to make vitamin D. Likely applies to many other countries.
- pwenzel 3y agoI live in Minnesota and the sun just came out in the beginning of May. I feel like I haven't felt real sun exposure since maybe October of last year. Let me tell you, I definitely take vitamin D supplements in the cold season! As an aside, I also drink Mushroom Hero tea all winter. Love that stuff.
- dukeyukey 3y agoYou literally cannot absorb significant amounts of vitamin D over winter in vast swathes of the world, including most of Europe.

- Escapado 3y agoGerman reporting in. According to Weatherspark [1] starting November to March around 70% of the days are cloudy and it's cold so you would barely expose 15% of your body to the remaining sun. In feburary, around midday, on a cloudy day you don't make enough vitamin d. And even on a cloudless day it takes more than 4 hours around midday to get the daily recommended dose. [2]. Being a dog owner I spend a lot of time outside, also during midday and 3/4 of the year I go for a run around midday every other day. Last year in january I was diagnosed with severe vitamin D deficiency at around 6ng/ml. Took a few months to get that back to normal using supplements.

- persedes 3y agoIn NC USA, even with regular walks, running and biking my Vitamin D levels were too low.
- Broken_Hippo 3y agoI wear long sleeves or a light jacket for most of the summer, so it doesn't always matter. And it is pointless in winter - 4.5 hours between sunrise and sunset, with the sun at a low angle. I'm fairly far north.
- andreasscherman 3y agoYou would be surprised how seldom you can get Vitamin D from the sun for many places! https://whencanigetvitamind.com https://whencanigetvitamind.com
- nibbleshifter 3y agoIn much of the northern hemisphere for most of the year this is insufficient. Even a really long walk.
