Twinlab Consolidated Holdings is a marketer and distributor of branded nutritional supplements, sold primarily through health and natural food retailers in the U.S. and internationally. Core products include vitamins, minerals, collagen, resveratrol, sports nutrition, herbal teas, and diet and energy supplements, sold in capsule, tablet, softgel, powder, and liquid forms. Twinlab operates a multi-brand portfolio: the flagship Twinlab brand covers heritage vitamins and supplements; Reserveage Nutrition targets premium anti-aging and beauty categories; ResVitale covers anti-aging supplements sold through GNC and online; Alvita is a heritage herbal tea brand; and Metabolife covers diet and energy products for mass market retail. Twinlab sells through specialty supplement retailers like GNC and Vitamin Shoppe, health and natural food retailers like Whole Foods and Sprouts, mass market retailers, e-tailers like Amazon, and direct-to-consumer websites. Twinlab does not manufacture its own products — contract manufacturers produce all goods to Twinlab's specifications, making the business asset-light with only about 7 employees. Twinlab's economics depend on the spread between contract manufacturing costs and retail pricing, with operating costs concentrated in sales, marketing, broker commissions, and supply chain management. Customer concentration is meaningful, with the top three customers representing roughly 53% of sales in 2024 and the largest single customer accounting for about 24% of sales.
