    NEUROACTIVE STEROIDS: EFFECTS AND MECHANISMS OF ACTION
    doi:10.1016/j.psyneuen.2009.07.003

    This is a mini-review of vitamin D3, its active metabolites and their functioning in the central nervous system (CNS), especially in relation to nervous system pathologies and aging. The vitamin D3 endocrine system consists of 3 active calcipherol hormones: calcidiol (25OHD3), 1α-calcitriol (1α,25(OH)2D3) and 24-calcitriol (24,25(OH)2D3). The impact of the calcipherol hormone system on aging, health and disease is discussed. Low serum calcidiol concentrations are associated with an increased risk of several chronic diseases including osteoporosis, cancer, diabetes, autoimmune disorders, hypertension, atherosclerosis and muscle weakness all of which can be considered aging-related diseases. The relationship of many of these diseases and aging-related changes in physiology show a U-shaped response curve to serum calcidiol concentrations. Clinical data suggest that vitamin D3 insufficiency is associated with an increased risk of several CNS diseases, including multiple sclerosis, Alzheimer's and Parkinson's disease, seasonal affective disorder and schizophrenia. In line with this, recent animal and human studies suggest that vitamin D insufficiency is associated with abnormal development and functioning of the CNS. Overall, imbalances in the calcipherol system appear to cause abnormal function, including premature aging, of the CNS.

Vitamin D can save half million babies each year: study - foodconsumer.org - 1 views

    "Friday Oct 16, 2009 (foodconsumer.org) -- Results of a new trial presented at an international research conference in Bruges suggest that vitamin D supplementation can reduce the risk of premature births and boost the health of newborn babies, the Times reported Oct 10.

    Vitamin D deficiency, which is common everywhere, has been linked in many previous studies to a variety of illnesses from heart disease, cancers, multiple sclerosis
    and many others.

    In the trial, Dr. Bruce Hollis and Dr. Carol Wagner of the Medical University of South Carolina, Charleston, gave one group of pregnant women 4,000 IUs per day of vitamin D at about three months of pregnancy. They gave a second group 400 IUs per day, amounts recommended by U.S. and UK"

    Low levels of vitamin D may raise a person's risk of premature death, a study by Johns Hopkins researchers shows.

    The research followed other recent studies showing low levels of vitamin D are linked to certain cancers, diabetes, and bone and immune system problems, but this is the first research to connect vitamin D deficiency to a higher risk of death
