I am thinking of buying time release vitamins. Are they helpful?

No, time release vitamins are ideal for people who are forgetful, not compliant and ill. The time release vitamins once absorbed release a small amount of the vitamin over the course of 24 hours. However, these vitamins are many times more expensive and are of no practical use. If you are too lazy to take your vitamins, then you certainly are too lazy to exercise. For you the problem is not a time release vitamin but a kick up the backside.
