Capsules have some advantages in certain uses, and so do tablets. Capsules can increase the cost to the end user, and it generally takes more capsules to contain the nutrients found in tablets. If the bottle is allowed to get too warm, capsules can melt or stick together. And capsules have to be digested (broken down) before the nutrients inside can be released. On the "plus" side, capsules are generally easier to swallow, and the preferred delivery form for some liquid nutrients that can't be tableted. A reputable company will not be tied exclusively to capsules OR tablets, but will select the delivery method that is most appropriate for the ingredient or the intended product user.
