- The sunshine vitamin, good ol' Vitamin D. It's one of the biggest health benefits of sunlight exposure. But how do we go from a sun shiny day to creation of an entire nutrient?

Hi, I’m Patrick. I’m a freelance science writer based in the San Francisco Bay Area. I hold a bachelor’s degree in Athletic Training and a master’s in clinical exercise physiology. I used to work in the clinical setting as a certified athletic trainer, physical therapy aide, and a certified strength and conditioning specialist. After working in the clinical setting, I went back to school and became a teacher. The goal of my content is to help normal people, not just pre-med students, learn about the human body. That might mean explaining a topic from an anatomy class or exploring a topic from medical history.

This video is starting to get some search traffic, so I want to clarify something. While the claims I made about Vitamin D’s health benefits (cancer prevention, and a role in the immune system) have evidence, you should ALWAYS question what you hear on the internet. I can’t stand oversimplified statements about science, and I breezed over all those claims too quickly (like effect size or even what I mean by “a role in the immune system”). The video is still true, but I wish I had gone into more nuance when writing this script. Take care!
Your a boss! Screw them
Can I still get vitamin D IF IM IN MY CAR ?
I need a lot but I get cold easily and my car gets huts from sun but is cold outside
If you cover tour arse too much, no Vit D for you.
Uh oh big pharma threatened you huh?
As an Irish person I would like to ask, what is this "Sun" you speak of? Sincerely, a nation with a combined Vitamin D intake of 3micrograms a year.
The lighter the skin the less sun needed.
So it works out
Lol. Thanks for the laugh.
A pain in the ass half of the year, that’s what it is lol sincerely, a winter lover
Closer to equator, higher % of sun radiation type B.
Even with cloud cover, you will still recieve the UVB radiation. Ever get sunburned on a cloudy day? I have.
My husband used to work third shift. His levels were too low, so the doctor put him on a vitamin D prescription. I guess that's common for third shift workers.
Thanks for the great video!
I worked those shifts, randomly though. A more accurate way to describe that shift is call it "night shift". 😊
I think it is essential when discussing vitamin D in a video to specify each type of vitamin D (D, D2, D3, etc.) to avoid ambiguity. Additionally, it may be more accurate to avoid using "more important" or "more useful" when referring to vitamins or micronutrients. Instead, it is important to emphasize that vitamins are not stored in the body and are washed away daily through processes like urination and sweating.
When people refer to vitamin D deficiency, they often refer specifically to low levels of vitamin D3.
- While vitamin D3 is generally more effective than vitamin D2 at raising and maintaining vitamin D levels in the body, both forms are still used to treat and prevent vitamin D deficiency. However, there is ongoing debate and research about the relative effectiveness of D2 versus D3.
- Both forms of vitamin D (D2 and D3) are important for overall health. Vitamin D plays a crucial role in calcium absorption, bone health, immune function, and other physiological processes. Therefore, neither form can be considered unimportant for overall health.
Great content family. Really shed some "light" on the subject. Peace and wellness to you
This is the pun comment I've been waiting for
Excellent educational video! Thank you for adding all your research. I subscribed. Sending love from Canada.
Watching this while bathing at the sun...with background song "you are my sunshine"⛱️
Great video, great content, great RUclipsr!
Thanks Patrick
Thanks Maryam, hope you're doing well :)
I hurt my shoulder friday and I'm feeling pretty good on monday.
Great content, subscribed!
very well-explained video! thank you!
I disagree.
Closer to the equator, a higher percentage of sunlight consists of type B radiation. Approximately 95% of the UV radiation that reaches the Earth's surface is UVA, while the remaining 5% is UVB. These percentages can vary depending on factors such as time of day, season, and geographical location. However, the 5% figure represents the maximum proportion of UVB radiation.
I had -20 vitamin D levels ( I did blood test ) . I sat in sun for 2 hours and my skin got darker lol
Must be quite hot to sit in the sun 😄
I am curious about the mechanism that turns 7-dehydrocholesterol to D3. Does the sun blast off some parts of the molecule?
You can get almost all of that with prescription or otc meds/vitamins too. VitD helps with pretty much everything.
0:58
When you think back on the old days and remember something cringey that you've done
*sigh*
Soooo... how is 7-dehydrocholesterol formed?
Could we not have uv bulbs indoors for people with deficiencies? Obv it would need to be toned to the right dose. Not everypne can get enough daylight due to working hours etc so this option would help that, no?
I have 4 vitamin d levels , ( took a blood test) . Is it bad?
MORE ON THIS ALOT MORE
thx dude nice video
Glad it helped
Our body really needs this vitamin D. Cause is very important to us
What is the dehydrocholesterol ?
I wonder how tis affects people who are heavily tattooed... i don't think it's a good idea to get a full sleeve because maybe that could block this whole proces ? who knows how that ink responds to sunlight and how the body reacts to it ...
Mushrooms also have vitamin d!
Since eating basically a carnivore I no longer get sun burn if a light pink gone the next day.
Vit D is one of the safe ones when worrying about overdose.
I love your chiseled jaw line
In Arizona, everyone has to stay in the shade in the summer.
I went to grad school at ASU. Summer time was spent migrating from QTs to campus to home and that's it.
I'm fair skin so I head for the shade.
Sometimes is very cold outside but sunny
It's hard to keep life on track

All you need to care about in any cold or shine: % of sun radiation type B.
Welcome to Canada - where 40% of the population is deficient all winter, but only 25% through the summer. I bet quite a bunch of the billion people who are deficient are in latitudes where even on clear days in the winter, there's just not enough UVB for the very limited amount of time most people spend outside and the necessity of keeping maximum skin heavily covered.
prysmcat I saw a UVB exposure map for America, and for most of the year, everyone in the Pacific Northwest and higher latitudes were getting close to nothing. I can imagine it’s worse up north!
0:59 and thats a selfburn
Can I still get the vitamin if am inside my car ?
Yes. If you keep chewing your salmon/mushroom sandwich. 😊
I have to take D3 supplements because I don't go outside often.
Yet, we arrested a man for surfing by himself during COVID..
The world makes so much sense.. especially politics
Go vitamin D
Correction: vitamin D3.
"In small doses it's fine"
How small are we talking about here? I need real numbers not words.
Thanks for asking! For future reference, I always put my sources in the description, so you're welcome to check there. The proper answer is long, which is why I shortened it:
"ESCP suggests that the maintenance tolerable upper limits (UL) of vitamin D, which is not to be exceeded without medical supervision, should be 1000 IU/d for infants up to 6 months, 1500 IU/d for infants from 6 months to 1 year, at least 2500 IU/d for children aged 1-3 years, 3000 IU/d for children aged 4-8 years, and 4000 IU/d for everyone over 8 years. Higher levels of 2000 IU/d for children 0-1 year, 4000 IU/d for children 1-18 years, and 10000 IU/d for children and adults 19 years and older may be needed to correct VDD"

@@Corporis thanks
Literally just go get tested, it is not too expensive and you can know right away where you stand because it will show where you are and what are the expected limits.
How do our cousins the great apes get vitamin D with them covered in fur?
Perhaps not having an "indoors" to be at the whole day?
Fat in the fur is converted and later absorbed by the skin. Cows, chickens and sheep all do it that way. And i even had vitamin d pills, made from the washed off fat from sheep's wool.
I was not a flea, tree, pea, or tree only a fair skin man doing vit. D now with calcium and msm
The way you move your mouth is... interesting haha
"Not a problem for americans"
*glares in PNW*
i believe lighter skin tones should stay in the north and darker ones in the south is lessens variation and problems i think 😅

Awfully thin on information....
Hey there! You can find follow up reading and the sources used in the description. Is there any particular information you were looking for?
its a 4 minute video, what do you expect?
