RA Treated by Vitamin D
- Several rheumatic diseases treated by high-dose vitamin D, but made worse if Calcium was added – April 2022
- Rheumatic Diseases often treated by Vitamin D, may need 40-60 ng – Oct 2021
- Rheumatoid Arthritis pain reduced by monthly 100,000 IU of Vitamin D – Oct 2018
- Rheumatoid arthritis reduced by 440,000 IU of Vitamin D over 4 months – Oct 2015
- Connective tissue disorders (Lupus, RA, etc) treated by vitamin D – May 2016
- 43 percent of Rheumatoid Arthritis patients have Vitamin D prescriptions (15 countries) – June 2017
- Big increase in vitamin D supplementation in just 2 years after Swiss rheumatology report – Dec 2013
- High dose vitamin reduced pain of fibromyalgia, osteoarthritis, and rheumatoid arthritis - July 2015
- Note: Vitamin D receptor problems (such as RA) are best treated by infrequent large doses of Vitamin D

Vitamin D [1,25(OH)2D—calcitriol] is basically a steroid hormone with pleiotropic biologic effects, and its impact on the regulation of immune system may influence several clinical conditions. Calcidiol (25OHD), as precursor of calcitriol, derives, for the most part (80%), from cutaneous cholesterol (7-dehydrocholesterol) under the action of UV-B (sunlight). Consequently, serum concentrations fluctuate during the year following the circannual rhythm of sun exposition. We will update about the available evidence regarding the complex influence of seasonal vitamin D changes on two different chronic connective tissue diseases, namely rheumatoid arthritis (RA) and systemic sclerosis (SSc). Notably, RA is an emblematic model of autoimmune disease with prevalent joint inflammatory features, while SSc is mainly an autoimmune progressive pro-fibrotic disease. However, in both conditions, low serum concentrations of 25OHD are involved in the pathogenesis of the diseases, and emerging data report their impact on clinical manifestations.
