Vitamania tells how and why vitamins have become so important to so many Americans. Rima Apple examines the claims and counterclaims of scientists, manufacturers, retailers, politicians, and consumers from the discovery of vitamins in the early twentieth century to the present. She reveals the complicated interests--scientific, professional, financial--that have propelled the vitamin industry and its would-be regulators. From early advertisements linking motherhood and vitamin D, to Linus Pauling's claims for vitamin C, to recent congressional debates about restricting vitamin products, Apple's insightful history shows the ambivalence of Americans toward the authority of science. She also documents how consumers have insisted on their right to make their own decisions about their health and their vitamins.
