Rheal Energy Bars get their caffeine from Guarana, a naturally energising berry that has been used for centuries in Brazil. Containing four times the caffeine of coffee, Guarana delivers a smooth, sustained energy boost without the jitters or crash, thanks to its slow-release caffeine. Not only does it provide lasting energy, but it also offers additional health benefits, including antioxidant properties that support overall wellbeing – making each bar the perfect snack to fuel the body.
Charlotte and Sean founded Rheal in 2016 under the name Super U, inspired by their personal health challenges. Charlotte's struggle with Coeliac Disease and Sean's battle with Hodgkin’s Lymphoma motivated them to incorporate superfoods into their diet, leading to noticeable health improvements. This experience drove them to create Rheal, offering convenient, nutritious superfood blends and drink mixes that are convenient for people to use everyday.
