RT Journal Article SR Electronic T1 Vitamin D deficiency treated by consuming UVB-irradiated mushrooms JF British Journal of General Practice JO Br J Gen Pract FD British Journal of General Practice SP 644 OP 645 DO 10.3399/bjgp08X341959 VO 58 IS 554 A1 Andrew Ozzard A1 Gurdip Hear A1 Gavin Morrison A1 Mike Hoskin YR 2008 UL http://bjgp.org/content/58/554/644.abstract AB Deficiency of vitamin D is usually caused by dietary deficiency and/or lack of exposure to sunlight in dark skinned individuals living at northern latitudes. Simple vitamin D deficiency is commonly treated by prescribing a vitamin D containing calcium supplement. This report presents a patient who rejected this approach and instead, after researching alternative treatment options independently, opted to self-treat by consuming UVB-irradiated mushrooms. The beneficial effect of this on the patient's plasma biochemical markers is shown. Further research into the beneficial effect of consuming UVB-irradiated mushrooms is required.
