Unfortunately, reduced sunlight hours in the winter, lack of outdoor time and use of sunscreen can easily lead to a vitamin D deficiency. Ideal vitamin D level • Promotes bone health and prevents osteoporosis or rickets • Protects against infections, for example cold Vitamin D deficiency and its relation to cardiovascular disease, autoimmune diseases, and even cancer and diabetes are also discussed in medical science.
