Vitamin D3 – Supplements for Psoriasis V

Another great supplement very helpful and not just for psoriasis is vitamin D3. However there are some people claiming that low vitamin D level in the body is the symptom of the disease rather than the cause and should not be raised with supplements. I think that at least in psoriasis (but probably in most diseases) the low levels of vitamin D in the blood are problematic and should be corrected.

To be outside under the sun is much better than taking the supplement of course but in the winter season there is no chance to get enough sunlight for those who live in the places on the planet where are summers and winters.

For now I am not aware of any studies that concluded the low vitamin D level in the body as symptom of the psoriasis. And I think that unless the studies will prove that it is, I will believe that low vitamin D levels should be corrected using the vitamin D3 and sunlight.

In my opinion the combination of the supplement with sunlight is better in many cases because chronic illnesses can interfere with ability of the body to make enough of own vitamin D3 in the skin.

And subsequently you still need well functioning liver and kidneys to convert the vitamin D3 and produce enough of active form of vitamin D from it – 1,25 dihydroxyvitamin D3. That’s why it is better in my opinion to take some vitamin D3 supplement even in the summer when you are in a process of healing some chronic illness like psoriasis. It can be convenient to have the blood levels of vitamin D3 monitored but more important is to watch how your body feels.

However the low level of 25-hydroxyvitamin D (the inactive* form of vitamin D which is checked in the laboratory) in the blood doesn’t have to be culprit in clearing up the psoriasis. It is very possible to clear up the psoriasis even with vitamin D deficiency. But it also depends individually on each person.

Also it is advisable to take vitamin K2 at doses about 200 mcg – 600 mcg a day since it works synergistically with vitamin D. Vitamin K2 helps with bone and teeth mineralization, prevents storing the calcium deposits in the blood vessels (hardening of the blood vessels) and soft tissues.

*Note: In the laboratory are checked the levels of inactive form of vitamin D: 25-hydroxyvitamin D (calcifediol/calcidiol) since it is more accurate than by testing the levels of active form – 1,25 dihydroxyvitamin D3 (calcitriol). It is so because the active form of vitamin D have half life in the blood about 4 – 8 hours but inactive form stays in the blood for a few weeks with the half life about 20 – 30 days. So it is more accurate because you will get level of the vitamin D that is not affected just by the last few hours but the level showing how much vitamin D your body have and had in the last days and weeks.

How much to take?

Doses for 175-200 lbs man (80 kg – 90 kg):

vitaminD3For those who have very low levels (severe deficiency) of this vitamin I think that 2 x 10 000 IU daily is safe for a few weeks or months. There are the studies that proved no negative effects at doses about 20 000 IU a day for a few months. But it also depends on if you are taking the vitamin D3 on an empty stomach when there is better absorption or if you take the supplement with or after meal.

For average man it is probably the best to take about 5 x 10 000 IU a week in five divided doses daily and also go out on sun.

Although the daily dose to avoid the illness caused by vitamin D deficiency – rickets is 200 IU (that’s what is officially stated as 100% of recommended daily intake in some countries) the scientific data have proved that this dose is very low to create health. Taking the 200 IU a day will probably avoid the rickets but the health is something else than just being rickets free. Vitamin D affects much more things in the body and not just the processes that affects the bone density.


If taking 200 IU would be really enough and considering the fact that the body create about 20 000 IU in about 30 minutes when the most of the skin of the body is exposed to direct sunlight, then we could say that about 18 seconds of sunlight a day is enough to be healthy. Which surely is not.

You can compare it with the plants. How tall, strong, healthy would be some plant that had enough sunlight (grow outside and has sunlight all day) vs. the plant that would grow inside and you would allow it to get the sunlight for just 20 seconds a day?
