Supple products, including Supple Liquid, are not sold at Walmart stores or in the company's online store. Walmart does carry a competing brand of glucosamine and chondroitin drink called Joint Juice.
Supple does not list any authorized retailers on its website. Instead, it encourages customers to order directly from the manufacturer. Ordering directly from Supple provides the customer with a 30-day satisfaction guarantee and guarantees that the product is genuine.
Supple Liquid only comes in peach mango flavor. The Joint Juice brand available through Walmart is available in multiple flavors, but only the blueberry acai flavor of Joint Juice is listed as a Walmart product as of April 2015.
