re: Do you think taking vitamins & minerals supplements does anything?

General answer is yes, they help when supplemented for someone who is deficient AND uses quality supplements which is usually the issue.

Absorption rates, eating/exercise regiment, water/electrolyte consumption, co-morbidities and prescription medication consumption are also major factors.

Don't waste time buying anything from CVS/Walgreens/Wal Mart, etc. You'll have to get with someone in the field for detailed recommendations but these are reputable companies that do their own quality control. FDA doesn't regulate supplements so anything can get on the market (although let's not look into what they have approved that's been terrible for the general public). As in Nature Made can put 5% Vitamin C and the rest fillers. They also make products in different forms that aren't effective.

Short list of reputable companies that put out consistent quality products:

BioClinic
MyoXcience
Standard Process
Douglas Labs
Transformation Enzymes
