    Benefits of Vitamin D Supplementation
    Joel M. Kauffman, Ph.D.
    Journal of American Physicians and Surgeons
    Volume 14 Number 2 - Summer 2009

    Clinical trials show that vitamin D supplementation at higher
    levels than previously recommended is beneficial for many
    conditions. It decreases the frequency of falls and fractures, helps
    prevent cardiovascular disease, and reduces symptoms of colds or
    influenza. Benefits are also seen in diabetes mellitus, multiple
    sclerosis, Crohn disease, pain, depression, and possibly autism.
    Sunlight does not cause an overdose of vitamin D production,
    and toxicity from supplementation is rare. Dose recommendations
    are increasing, but appear to be lagging the favorable trial results. A
    number of common drugs deplete vitamin D levels, and others may
    limit its biosynthesis from sunlight.
    People with adequate levels from sun exposure will not benefit
    from supplementation. While dietary intake is helpful,
    supplementation is better able to raise serum 25-hydroxyvitamin D ,
    the major circulating metabolite, to the level now thought adequate,
    30-50 ng/mL.
    Where there is inadequate daily sun exposure, oral doses of
    1,000-2,000 IU/d are now considered routine, with much higher
    doses (up to 50,000 IU) for rapid repletion now considered safe.

    Vitamin D and depressive symptoms in women during the winter: a pilot study.
    Shipowick CD, Moore CB, Corbett C, Bindler R.
    Appl Nurs Res. 2009 Aug;22(3):221-5.
    PMID: 19616172
    doi:10.1016/j.apnr.2007.08.001

    ESULTS: Vitamin D supplementation was associated not only with an increase in the serum D levels by an average of 27 ng/ml but also with a decline in the BDI-II scores of an average of 10 points. DISCUSSION: This study suggests that supplemental vitamin D3 reduces depressive symptoms.

    Vitamin D and mood disorders among women: an integrative review.
    Murphy PK, Wagner CL.
    J Midwifery Womens Health. 2008 Sep-Oct;53(5):440-6. Review.
    PMID: 18761297

    Four of six studies reviewed imparted significant results, with all four showing an association between low 25(OH)D levels and higher incidences of four mood disorders: premenstrual syndrome, seasonal affective disorder, non-specified mood disorder, and major depressive disorder. This review indicates a possible biochemical mechanism occurring between vitamin D and mood disorders affecting women, warranting further studies of these variables using rigorous methodologies.

    Can vitamin D supplementation prevent winter-time blues? A randomised trial among older women.
    Dumville JC, Miles JN, Porthouse J, Cockayne S, Saxon L, King C.
    J Nutr Health Aging. 2006 Mar-Apr;10(2):151-3.
    PMID: 16554952

    CONCLUSIONS: Supplementing elderly women with 800 IU of vitamin D daily did not lead to an improvement in mental health scores.

    Vitamin D vs broad spectrum phototherapy in the treatment of seasonal affective disorder.

    J Nutr Health Aging. 1999;3(1):5-7.
    PMID: 10888476

    All subjects receiving vitamin D improved in all outcome measures. The phototherapy group showed no significant change in depression scale measures. Vitamin D status improved in both groups (74% vitamin D group, p < 0.005 and 36% phototherapy group, p < 0.01). Improvement in 25-OH D was significantly associated with improvement in depression scale scores (r2=0.26; p=0.05). Vitamin D may be an important treatment for SAD. Further studies will be necessary to confirm these findings..

Vitamin D3 and Solar Power for Optimal Health: Vitamin D and depression: how SAD! - 0 views

  •  
    Seasonal affective disorder (SAD) is a type of winter-time depression experienced by people those who live in northern latitudes such as those of New York, Seattle, all of Canada, and Northern Europe. I believe it is primarily a disorder of sunlight/vitamin D deficiency.
    Vitamin D, when administered in late winter, produces a positive effect on mood in only five days.[1] One theory for this is that vitamin D stimulates the brain to produce more serotonin. In a wintertime experiment, serum vitamin D levels doubled in six months through supplementation and dramatically increased scores on a wellbeing assessment.[2] Two groups were given either 1,000 IU or 4,000 IU of vitamin D daily. And although both groups improved, the higher dose produced better results.

Vitamin D May Not Be The Answer To Feeling SAD - 0 views

  •  
    ScienceDaily (Mar. 18, 2009) - A lack of Vitamin D, due to reduced sunlight, has been linked to depression and the symptoms of Seasonal Affective Disorder (SAD), but research by the University of Warwick shows there is no clear link between the levels of vitamin D in the blood and depression.
