David is of course right but it never occurred to me at the time so I carried on taking vitamin d, baby asprin, pomi-t, turmeric/black pepper tabs.
As an aside, vitamin d from the sun just gets rejected if we have too much. Vitamin d from tablets collects in muscle if we have too much which has long term issues I understand. The rec daily dose is 1000 iu however I have been taking 5000 a day as in my situation the long term effect is not my problem but a strong immune system now is. I also did not cut down on green tea.
I have no idea if my self medication is good or bad for me but personally I have got through 2 years without a cold or anything else so it works for me.
