Today, we’ll look at a few more things that might be
impacting your vitamin D levels.
1. Having cooler skin.
Yes, your temperature actually affects vitamin D
production.
Warm skin is more efficient at making vitamin D than
cooler skin is, so you make more vitamin D on a hot
day than on a cool one.
If it’s cooler outside, you’ll need to stay in the sun
longer to make the same amount of vitamin D that you’d
make in only a few minutes on a hot summer day.
2. Eating too much.
Fat cells actually absorb vitamin D.
It’s thought this might be a way for the body to store
vitamin D “for a rainy day” in case production or intake
of the vitamin is low.
However, studies have shown that being obese (a body
mass index of over 30) is actually correlated with l
ower vitamin D levels.
So being overweight may reduce the bioavailability
of your vitamin D.
3. Being older.
Older people have less of the
substance found in your skin that is converted by
UVB light into the vitamin D precursor than younger
people do.
This means they make less vitamin D naturally.
There’s also experimental evidence that says older
people are also less efficient at making vitamin D
than younger people.
The National Center for Health Statistics hasn’t
seen a huge drop in vitamin D levels between middle-aged
and older people, however.
This may be because many older people now take supplements,
or it could be that the effects of aging are less than
previously supposed.
4. Having an unhealthy gut.
The vitamin D you consume,
either in your food or as a supplement, is absorbed by
your small intestine immediately below the stomach.
This absorption is affected by several things: stomach
juice, pancreatic secretions, bile from your liver,
and even the integrity of your intestinal wall.
This means that any disorder that might affect the
gut, like Crohn’s disease, celiac disease, chronic
pancreatitis, or cystic fibrosis, can reduce the
amount of vitamin D your body absorbs.
5. Having unhealthy liver and kidneys.
If your liver isn’t producing enough bile, it may
lower the amount of vitamin D your intestines absorb.
Other types of liver disease can reduce the metabolism
of vitamin D or stop it entirely.
Vitamin D levels and kidney function tend to go hand
in hand. With normal kidneys, you have normal vitamin
D levels (usually), but as the kidneys fail, the
vitamin D levels go down.
