Hurdity, I was deficient after a wonderful summer a couple of years ago, I walk the dog every day for an hour so more than the recommended 10 minutes suggested as being adequate to maintain our vitamin d levels. My gp was very surprised that my level was so low hence needing a supplement. Maybe it's down to the individual as to whether or not their body can process it properly from sunlight and diet?

That does surprise me sparky! Do you walk about with bare arms etc though in the full sun during those months - just being outside isn't enough.
Vitamin D supplementation is recommended for all over 65 anyway although in the case of vit D I doubt this would be due to malabsorption as most of our Vit D can be obtained through the skin.
blossom60 - do you have any reference about this ie malabsoprtion in older people leading to vitamin deficiency - personally ( but I haven't read anything about it!) I would have thought that many really elderly people probably just don't eat a good enough diet with as much fresh food - since perhaps having ready meals etc?
