Evidence has shown that low blood vitamin D Levels are associated with increased risk for heart disease, diabetes, depression, dental caries, osteoporosis, and periodontal disease, all of which are either considered risk factors for dementia or have preceded incidence of dementia.
Vitamin D and Pregnancy: It appears that vitamin D insufficiency during pregnancy is potentially associated with increased risk of preeclampsia, insulin resistance and gestational diabetes mellitus. Sufficient amounts of Vitamin D is critical for fetal development, especially fetal brain development and immunological function.
Vitamin D and Peripheral Neuropathy: The results suggest that active vitamin D3 could treat peripheral neuropathy by inducing NGF (nerve growth factor) production in the skin.
Vitamin D and MS Cancer: Results from ecological, case control and cohort studies have shown that vitamin D reduces the risk of bone fracture, falls, autoimmune diseases, type 2 diabetes, CVD, and cancer.
Vitamin D and Lupus (SLE) and Fibromyalgia: Patients with systemic lupus erythematosus (SLE) and fibromyalgia (FM) tend to have low vitamin D levels (<50 nmol/L), a level at which parathyroid (PTH) stimulation occurs. If PTH stimulation occurs, calcium will be drawn from the bones, and risk for osteoporosis will increase. This could be due to the limited sun exposure many patients in this group receive.
Summary and Dosage: Vitamin D is both a hormone and a vitamin. Supplementation should be with the active vitamin D3; 15 min of sun exposure 3 times per week is adequate for most people, although logistics and concerns about skin cancer make supplementation a viable option. Recommended does for vitamin D have been changing as the benefits of supplementation have become evident; however it is prudent to treat this fat soluble vitamin with respect. Simple inexpensive blood test can determine your vitamin D level so the appropriate dose of vitamin D can be selected. Chiropractic Physicians are well suited to test and treat Vitamin D deficiencies. Vitamin D supplementation should only be done under the supervision of a doctor as overdose of Vitamin D can cause hypercalcemia (too much calcium in the blood) which can cause abnormal heart rhythms among other overdose side effects.
