Vit D level (Tot, D3 or D2?)

Stef,

Is it the total Vit D important or the individual type of Vit D? I just got a test with the following results:

Vit D 25OH total: 58 ng/mL
Vit D 25OH, D3: 58 ng/mL
Vit D 25OH, D2: < 4mg/mL

Vit D2 seems to be quite low.

Thanks

Thanks for you two. I just want to make sure that I don't have Vit D deficiency in addition to hbv, without hoping it can cure hbv.

9 things that can undermine your vitamin D level

According to 2011 National Center for Health Data statistics, almost one in three Americans has vitamin D blood levels below 20 nanograms per milliliter (ng/ml), the threshold that the Institute of Medicine (IOM) says is needed for good bone health. Some experts say even higher levels are needed.

Figuring out all the factors that can affect a person’s vitamin D levels is complicated. You can get the vitamin from food (mainly because it’s been added; few foods are natural sources of vitamin D) and by taking supplements (many doctors recommend taking 800 IU of vitamin D3 a day).

But vitamin D is also produced by the body in a complex process that starts when rays in the invisible ultraviolet B (UVB) part of the light spectrum are absorbed by the skin. The liver, and then the kidneys, are involved in the steps that eventually result in a bioavailable form of the vitamin that the body can use.

A review paper about the many factors influencing a person’s vitamin D levels appeared in 2011 in Acta Dermato-Venerologica, a Swedish medical journal. Here are nine interesting factors identified in the paper:

1. The latitude where you live. At higher latitudes, the amount of vitamin D–producing UVB light reaching the earth’s surface goes down in the winter because of the low angle of the sun. In Boston, for example, little if any of the vitamin is produced in people’s skin tissue from November through February. Short days and clothing that covers legs and arms also limit UVB exposure.

2. The air pollution where you live. Carbon particulates in the air from the burning of fossil fuels, wood, and other materials scatter and absorb UVB rays. Ozone absorbs UVB radiation, so holes in the ozone layer could be a pollution problem that winds up enhancing vitamin D levels.

3. Your use of sunscreen — in theory. Sunscreen prevents sunburn by blocking UVB light, so theoretically, sunscreen use lowers vitamin D levels. But as a practical matter, very few people put on enough sunscreen to block all UVB light, or they use sunscreen irregularly, so sunscreen’s effects on our vitamin D levels might not be that important. An Australian study that’s often cited showed no difference in vitamin D between adults randomly assigned to use sunscreen one summer and those assigned a placebo cream.

4. The color of your skin. Melanin is the substance in skin that makes it dark. It “competes” for UVB with the substance in the skin that kick-starts the body’s vitamin D production. As a result, dark-skinned people tend to require more UVB exposure than light-skinned people to generate the same amount of vitamin D.

5. The temperature of your skin. Warm skin is a more efficient producer of vitamin D than cool skin. So, on a sunny, hot summer day, you’ll make more vitamin D than on a cool one.

6. Your weight. Fat tissue sops up vitamin D, so it’s been proposed that it might be a vitamin D rainy-day fund: a source of the vitamin when intake is low or production is reduced. But studies have also shown that being obese is correlated with low vitamin D levels and that being overweight may affect the bioavailability of vitamin D.

7. Your age. Compared with younger people, older people have lower levels of the substance in the skin that UVB light converts into the vitamin D precursor, and there’s experimental evidence that older people are less efficient vitamin D producers than younger people. Yet the National Center for Health Statistics data on vitamin D levels fly in the face of the conventional wisdom that vitamin D inadequacy is a big problem among older people. They don’t show a major drop-off in levels between middle-aged people and older folks.

8. The health of your gut. The vitamin D that is consumed in food or as a supplement is absorbed in the part of the small intestine immediately downstream from the stomach. Stomach juices, pancreatic secretions, bile from the liver, the integrity of the wall of the intestine — they all have some influence on how much of the vitamin is absorbed. Therefore, conditions that affect the gut and digestion, like celiac disease, chronic pancreatitis, Crohn’s disease, and cystic fibrosis, can reduce vitamin D absorption.

9. The health of your liver and kidneys. Some types of liver disease can reduce absorption of vitamin D because the ailing liver isn’t producing normal amounts of bile. With other types, steps essential to vitamin D metabolism can’t occur — or occur incompletely. Levels of the bioactive form of vitamin D tend to track with the health of the kidneys, so in someone with kidney disease, bioactive vitamin D levels decrease as the disease gets worse, and in end-stage kidney disease, the level is undetectable.

hbvdna (under tnf)(4/19/2011): < 126 copies
AST/ALT(5/13/2011): 20/24

No hnsag test in USA. Fyi. I am hbsab negative. biopsy S0. Also I am taking 2000IU Vit D3 everyday. The Vit D test was done after some beach vacation.

we dont make vitamin d 2 and if we have some it can only be from d2 suppl, so you can check both total d2+d3 or only d3
only d3 is a good supplement source

58ng/ml is a very good level, do you have detactable hbvdna or abnormal alt/ast, low hbsag?
