Are supplements taken as sprays more effective than pills?

An increasing number of supplement products are appearing on the market that are based on the idea that substances are absorbed better if sprayed into the mouth rather than taken as capsules or tablets. The merit of this concept is debatable, according to an article in the Los Angeles Times. Although certain specific substances have been shown to be well absorbed sublingually (under the tongue), there is no reason to think that this process works for substances in general. Each substance needs to be tested individually, and these tests generally have not been done.
