Mannatech Inc. is a multi-level marketing company (MLM) founded in 1993 by Samuel Caster. Headquartered in Flower Mound, Texas, it's a publicly traded company on the NASDAQ exchange under the symbol MTEX. Mannatech focuses on selling dietary supplements and personal care products through a network of independent sales representatives.
Mannatech's core principle centers around a concept they call "Glyconutrition," which emphasizes using plant-derived ingredients to deliver targeted nourishment to cells. Their product line includes a variety of dietary supplements aimed at promoting health and wellness in areas like immune function, weight management, and skincare. They also offer personal care products that supposedly align with their Glyconutrition philosophy.
The company has faced some controversy surrounding the effectiveness of their products and the MLM business model. Critics argue that the focus on recruiting salespeople over product sales can overshadow the legitimacy of the products themselves. Additionally, some health claims made about Mannatech's supplements haven't always been substantiated by rigorous scientific evidence.
Despite the controversy, Mannatech maintains a loyal customer base and a network of independent sales representatives. They continue to develop and market new products, touting the potential benefits of Glyconutrition.
