Thanks for your comment. When I got home from my hospital visit, I contacted the hospital to advise them that the recommended daily dosage was 3,000 mg from the doctor and yet only 1,000 mg from their pharmacy. Their response was that if there is a discrepancy it is always better to follow the Doctors recommendation.
In addition to yourself I also contacted a highly respected pharmacist in Pattaya whose view was the same as yours and even said that for someone over 80, 500 mg a day might also be enough.
I have been feeling extremely tired all day since taking the tablets and wondered if this was a side affect.
It surprises me that highly respected hospital can make such a mistake which could seriously affect my health and then instead of admitting their mistake, dangerously advise me to continue with the excessive dosage.
I am for several years now in recovery from cancer and serious heart trouble and this new stress is very difficult for me to cope with.
I will continue with one tablet, twice a day and hope things improve.
As usual many many thanks for your help.
