If you have a medically confirmed vitamin or mineral deficiency, then you might need a supplement. Otherwise, your body just filters out all the supplements that you take.
There is research just getting underway that examines the long-term effects of taking large doses of vitamins and minerals you don’t need. It probably is not a healthy practice.
lots of people dont assimilate the supplements that they take...
many of us...in the millions its suspected.. cant assimilate many of the supplements available
Not all supplements are compounded the same...hence the wide...range of opinions on whether...supplements IN GENERAL ..work.
further diferent forms of vitamins are absorbed at diferent rates. intravenous vitamin c is able to be absorbed and used by the body at a much higher rate than vitamin c taken orally, and you can take more via iv than oral without a possible irritable gut situation. there are certan forms of b vitamins tht can be better absorbed than others. ubquinol, a different form of coq10, can be better absorbed by elderly folks than regular coq10.
also dosing may be a factor why it doesn’t work for some people. too little and no effect.
