For years doctors encouraged people to take supplements and then in later years articles and some doctors claimed supplements only made expensive urine.
Now I am reading that taking some vitamins can actually cause harm, and they were the ones doctors encouraged people to take. Vitamin E and C are two in the more recent articles. In earlier years Vitamin E was suppose to be the wonder vitamin for most everything. I have been cautioned to take very little vitamin C for various reasons, get C from foods rather than supplements. Vitamin E caused restless legs for me, stopped E and legs settled down.
If you have an illness and more vitamins are needed above what is in food, then take only what is needed in normal doses.
Eating a balanced diet, exercise, control weight, no recreation drugs, no smoking, no alcohol, etc. will go a long ways in keeping a person looking young. Yes, you can still have a blast without bad vices, I did and at age 74 I have no wrinkles, look younger than other ladies my age and many younger ladies too. No, it is not just my eyes telling me this, I get complimented frequently from others outside of the family.
