As of 2015, beet juice is available at several retailers' websites, such as Amazon.com and Walmart. It is also available online at vitamin and supplement shops, such as VitaminShoppe.com.
Beet juice may also be available in local retail stores. Amazon.com and Walmart.com offer some similar brands of beet juice, with at least one being cheaper on Amazon. VitaminShoppe.com offers a greater variety of beet juice and sells related products from several different speciality brands, such as Pines International. However, most of the actual beet juice is in the form of a powder that the consumer must mix prior to drinking.
