Are liquid supplements better than solid?

Manufacturers of liquid-based supplements come up with all kinds of claims to convince the dieter that their form of supplementation is more effective than their capsule- and tablet-based counterparts. But is there any substance to this?

For instance, the company that markets Calorad, a liquid dietary supplement, claims it may be superior to the competition because of its purported ability to be absorbed into the body more quickly and efficiently.

While liquid may, to a certain extent, be absorbed more readily into the bloodstream, this does not necessarily mean it is superior to capsule-based supplements -- especially if the formula contains sub-par ingredients. And lo and behold, this particular product may not really contain eye-catching ingredients like Hoodia and Advantra-Z.
