Hello there. I can understand your concern. No tablets are not at all necessary if you are have a well balanced diet. But most of us are so busy in our daily lives, that we are not able to get adequate nutrients from the fast food kind of diet we are on. So it's not necessary that you take a tablet daily, but for those who are not on a proper diet, need a supplement. Best regards. Dr. Anil Kumar Jain. Bangalore.
