Gary Moller's old blog about health, fitness, nutrition, medicine, lifestyle and related topics.
People from the UK or anywhere in the Northern Hemisphere above latitude 45N listening to this need to be aware that Wellington NZ where Gary is speaking from, is not only much nearer the Equator than we are but also because there is more sea in the Southern Hemisphere there is less pollution and so more UVB gets through to ground level. Also as the earth orbits the sun it tilts and this tilting means that when it's Winter in New Zealand the Southern Hemisphere is actually nearer the sun than is when it's Winter in Scotland. These two additional factors mean that we are far more likely to be more seriously Vitamin D insufficient that the New Zealander's.
This report http://www.ajcn.org/cgi/content/abstract/85/3/860
Hypovitaminosis D in British adults at age 45 y: nationwide cohort study of dietary and lifestyle predictors shows most of us have low status and therefore may need more than the 2000iu that Gary is suggesting is adequate in NZ.
Risk assessment for vitamin D
http://www.ajcn.org/cgi/content/full/85/1/6 shows under 10,000iu is safe but as your body uses only 4000iu/d this would be a sensible maximum for UK/Scotland use between October and March with 1000-2000iu being a suitable level for those above latitude 45n for summer use.
