Q. I have had psoriasis for more than 35 years. A few years ago, my doctor suggested vitamin D, as my blood level was low. Much to my surprise, my psoriasis began to disappear almost immediately.
Several patches had proved impossible to cure with other medications. When my blood test showed a normal level of vitamin D, the doctor asked me to cut back the dosage. I did and the psoriasis returned.
I now take 5,000 units of vitamin D capsules per day and that keeps my psoriasis in check. Regular monitoring of my vitamin D level shows that I am in the middle of the acceptable range with this dosage.
A. Dermatologists have embraced topical vitamin D-like prescription creams, foams and ointments for psoriasis (American Journal of Clinical Dermatology, Aug, 2012). Calcipotriene (Calcitrene, Dovonex, Sorilux) is pricey, however.
Many doctors may have forgotten that oral vitamin D can also be helpful (Journal of Dermatological Treatment, online, Jan. 21, 2012). More than 25 years ago Japanese researchers noted that oral vitamin D3 reduced the symptoms of psoriasis without side effects (British Journal of Dermatology, Oct. 1986).
It makes sense to give inexpensive vitamin D pills a try, but anyone who uses a dose higher than 4,000 IU daily should ask the doctor to order a blood test, to make sure that the vitamin D level remains, like yours, in the healthy range. We discuss vitamin D, the appropriate dose and how to interpret the blood test in our Guide to Vitamin D Deficiency.

    I have had pustular psoriasis on my scalp for some time. It has gotten worse, and while medications do help, the improvements are temporary and insufficient.

    I decided to try D3, as some people have reported that it may work.

    I have been taking 2000 mg now for a few weeks, and it seems to work far better than anything else. In fact, my condition is almost cleared. Time will tell whether it is placebo effect, a coincident with weather change or something else, but least for at the moment, it seems to have made a major difference. If it stays as it is, I will be entirely happy.

    Good luck.

    I have been taking 5000 IUD of Vitamin D3 and I can honestly say my psoriasis has seriously improved as a result of this. If only I had known 15 years ago this would have saved me so much stress and anguish. I simply cannot understand why Doctors are not recommending this alongside the creams.

      Medicine and Pharmaceutical industry is geared for profit…Maintenance is preferred to Cure….there are very few ‘cures’ available for anything….but if you need something to keep your ailment in check for a decade or two…you are spoiled for choice…
