Vitamin D insufficiency (serum 25(OH)D < 50 nmol/L) contributes to the pathogenesis of chronic diseases including osteoporosis, hypertension, diabetes, rheumatoid arthritis, and multiple sclerosis, and supplementation can improve clinical outcomes in these conditions.

Check your Vitamin D status if you have chronic conditions like hypertension, diabetes, or autoimmune issues, or if you are elderly. Current guidelines may not be enough to reach optimal levels for disease prevention. Supplementation can help reduce blood pressure, improve glucose control, and alleviate symptoms in conditions like rheumatoid arthritis and multiple sclerosis. Aim for serum 25(OH)D levels above 50 nmol/L, potentially requiring higher doses than standard recommendations.

Moreover, vitamin D insufficiency can lead to a disturbed muscle function. Epidemiological data also indicate a low vitamin D status in tuberculosis, rheumatoid arthritis, multiple sclerosis, inflammatory bowel diseases, hypertension, and specific types of cancer. Some intervention trials have demonstrated that supplementation with vitamin D or its metabolites is able: (i) to reduce blood pressure in hypertensive patients; (ii) to improve blood glucose levels in diabetics; (iii) to improve symptoms of rheumatoid arthritis and multiple sclerosis.
