Metamucil Commercial 2000

 Introduced in 1934 by G. D. Searle & Company, Metamucil was acquired by Procter & Gamble in 1985. The name is a combination of the Greek word for change (meta) and the class of fibre that it utilizes (mucilage). In its early years, Metamucil achieved sporadic drug-store distribution as a "behind the counter" brand. Since 1974, the brand was also marketed to consumers via print and TV advertising and became available in food outlets. Flavoured versions were added in 1979.

The brand is sold as powdered drink mixes, capsules and wafers in a variety of flavours. Metamucil contains psyllium seed husks as the active ingredient. It is manufactured in Phoenix, Arizona by Procter & Gamble.[24] When first marketed to consumers in 1974, Metamucil was marketed as a laxative. The advertising claim at that time was "If not nature, then Metamucil". Procter & Gamble sought to make Metamucil a household name by advertising in magazines and on television, using the claim "All-fibre is not created equal".
