The NIH guys also did a study that said that even in tropical countries, Vitamin D absorption has fallen dramatically because of lifestyle changes. One of the probable factors is the lust for fair skin. I routinely see people covered from head to toe to help them stay fair skinned, even kids are sent to play covered in full sleeve clothing. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3897581/

> One of the probable factors is the lust for fair skin. I think this must be cultural. Certainly in my experience in the United States, the lust is for tanned skin. There are even tanning salons, where one can lie down in a machine which floods one's skin with UV. Now, I personally love fair skin, and have never understood why others seem to love a tan so much.

Fathers family was Irish, Mothers Scottish.

I burn in front of a monitor, I have fair skin because factor 50 and covering everything I can are simply required.

About once every 6 months I remember to start taking my vit D supplements again. I've always taken more than the recommended dose because vitamin D is not extremely bioavailable in pill-form, and I notice amazing improvements in mood, mostly. Usually I am sad in the mornings. I have a cup of coffee, browse around on HN, and then convince myself to do work, and the sadness goes away with the distraction, and by the ev…

Same experience for me. The University of Washington headache clinic recommended Vitamin D and Magnesium supplements and it made a marked difference in my mood. Turns out having constant mild headaches is pretty depressing.

Have to be careful with magnesium, too much and you'll spend the entire day on the toilet been reminded that topologically humans are a tube.

My doc prescribed me 25,000 IU once a week for 8 weeks then 10,000 IU daily thereafter. The kicks of 25k were what made the diff for me. YMMV

holy smokes, thats a ton. Are there any effects of too much?

Yah like doing 25k a day. That could cause problems.

My electrician father who spent several years working on rooftops in Houston and developed skin cancer on his hand at 51 would beg to differ.

Antidotes are not data. We have no reason to believe from your story that your would not have got skin cancer if he had spent all his time in a cave. Or maybe he wouldn't have, because he would have died of something even worse at 45. Science is trying to work this out, it is complex. We know that sun exposure both protects from and causes skin cancer depending on the study. This is a complex subject, the only thing…

In this case his one point of data would be enough to refute the original claim.

This effect is more pronounced with lower-quality magnesium supplements, such as magnesium oxide, magnesium sulfate, and magnesium chloride. These compounds are insoluble in water (magnesium oxide), or their counter-ions are not absorbed (magnesium sulfate). Magnesium + glycine (specifically bisglycinate which is the magnesium salt with two glycine molecules) is more bioavailable and does not have a laxative effect since glycine is easily absorbed by cell walls. Magnesium citrate also does not have a marked laxative effect and is more bioavailable than magnesium oxide, but less bioavailable than magnesium bisglycinate.

Fair skin is a lot better than skin cancer!

I've known about the sunscreen misinformation for a long time. My dad died of malignant melanoma. He wore sun screen all the time. He didn't swim. He would wear sun hats. He was paranoid, and likely had premonition of it. Unfortunately, his prevention methods might have actually exacerbated his odds even further because he was depriving his skin of one of its few natural healing modalities.

What does that have to do with the price of tea in China? Not smoking doesn't mean you will not get lung cancer.

Related to this topic, if you have IBS/IBD, some interesting research been coming out in the last couple of years indicating that low vitamin D may play a role in this issue as well. This [1] 2015 study found 82% of people with IBS had low vitamin D levels relative to 31% in the control group. This [2] 2016 one proved causation of vitamin D supplementation improving symptoms, by randomly splitting into two groups and…

Thanks for this. I have IBS and began taking a 2000 IU supplement of Vitamin D awhile back for unrelated reasons. Maybe I'll bump it up to 3000 to see if it helps.

That seems to be too low to have an effect if you are actually deficient according to the study.

This supports my lived experience. Found to be incredibly low in vitamin D, and diagnosed with autoimmune thyroiditis. Doctor said to supplement with 2000 IU being the max per day. After seeing no improvement whatsoever in vitamin D levels, and after talking with others with the same issue, I self medicated to 10000 IU / day. Lo and behold my vitamin D levels went back up and my auto-antibodies went back down.

This is similar to my lived experience. I was diagnosed with Hashimoto's 3 years ago. I was lucky to find a great doctor that specialized in it. He put me on 15000 IU / day for 3 months because I was so severely low in addition to having high antibodies. Within 3 months my levels were so much better. I still take 10000 IU / day along with selenium, iron, fish oil and good diet/exercise and all my levels have been in…

Did you experience any other benefits from that regimen of supplements?

That's what the above poster already said. > people who were previously were at lower risk of cancer due to their skin pigmentation/higher melanin

Unless the above poster means “due to their [acquired] skin pigmentation” I don’t see how the comment can make any sense. Why would their rates of skin cancer be higher now?

Maybe OP is referring to spray tans? That's my best guess.

>>I know it sounds downright crazy, but it's possible that someone who's studied medicine and practiced it for years, actually knows better than random anonymous forum users. As the link in the OP actually denotes, no, that's not always the case. Bodybuilders and performance trainers - as well as Soviet Union sports scientists - have known for decades that Vitamin D supplementation is vital. This has been rejected by…

I don’t think that the drug regimes of the Soviet Olympic Teams should be held up as a good example to follow - a lot of damage was done to a lot of people. On a related note, the Russian team just got banned for trying that crap again. http://www.rollingstone.com/sports/news/russia-banned-from-2...

This is what's known as an ad hominem argument
