In 2007, Lululemon marketed its Vitasea garments as clothing made with seaweed fibers that supposedly offered anti-inflammatory, antibacterial, hydrating, and detoxifying benefits. The New York Times reported that laboratory testing found no significant difference in mineral levels between ordinary cotton T-shirt fabric and the Vitasea material. Canada's Competition Bureau then demanded that the company remove the health claims from products sold in the country. The incident exposed the uneasy boundary between technical apparel innovation and wellness marketing: Lululemon's language suggested that simply wearing a shirt could deliver physiological benefits, but regulators found the evidence inadequate. The episode became an early warning of the brand's tendency to sell clothing through quasi-medical and lifestyle claims that were more impressive than the available scientific proof.
