I believe most of us are already consuming, or would like to consume health supplements in our daily intake. Unless if you had a very healthy and balanced daily diet, almost everyone need to take some depending on your body and lifestyle.
I watched Dr Oz' tv show (he was a frequent in Oprah's before having his own show) some times ago and he actually recommended 3 supplements for everyone.
An excerpt taken from Dr Oz' website as below :
Even if the statement comes from a medical doctor, there is no absolute right or wrong about supplement intake. However I would like to emphasize that it is vital to consult somebody, be it your medical doctor, pharmacists or any product consultants that you personally know and believe, before you start to eat a single pill. The internet have abundance of information about this and is a good starting point if you're a curious cat regarding this issue.
Have fun exploring!
