Some people don't need Vitamin D as much?

I swear pale people don't need Vitamin D as much or some people genetically don't need as much and have adapted to not needing it. Cause if I don't get enough my skin breaks out and I feel sick, but other people that eat shit and aren't healthy i'm sure are Vit D defficienct and nothing happens to them

Whenever I read what you eat, it puts me back in my place as a total wuss. River lampreys? We're not worthy.

In all honesty though, I believe EVERYONE should be supplementing with Vitamin D nowadays unless you live in a tropical or on a coastal area like Florida or California.

There's a theory that Caucasian (particularly Northern and Eastern European people) require less sunlight, due to those particular regions not receiving much sunlight throughout the year, but the people in those regions are known for their vitality and health (or they were, until they were introduced to processed food.)

"I swear pale people don't need Vitamin D as much"

That's wrong. The paler you are, the less time you need to be in the sun to synthesize a specific amount of VitD.

Even people who eat crap might get enough VitD, as many processed foods are enriched with VitD. You might need more exposure to the sun than other people because: a)You are older than 65

b)You have problems with your kidneys, thyroid or liver

c)You have a chronic inflammatory disease in your gut

d)You are adipose

e)You have osteoporosis

f)You have a problem with alcohol

g)You have a problem with digesting fat

h)Your intestine doesn't function properly

i)You take medications against epilepsy

j)You are pregnant

k)You are breast-feeding

l)You have a genetic defect (a mutation of 1-??-Hydroxylase)

There would have to be different needs based on genetics, but there's also differences in serum level response to supplementation/sun exposure between people, which might be based largely on body fat. When I took 4000iu last winter, I hit 90ng/ml, which I felt was too high. My test result yesterday after taking 2000iu this winter was 52ng/ml, which is exactly there I wanted it.

Highest level that i got naturally was 108 nmol/l from sunshine alone. It was after 6-7 months of walking around shirtless. I dont know how high i get from supplements. Will do a first blood test supplemented in a month. I think around ~110 is good value for pale northern people. I also eat a lot of vitamin d rich foods, like river lampreys (they have over 25??g of vitamin d per 100grams, also 2500??g of vitamin A), burbot liver etc and herrings, bone marrow?.
