Guarana
Guarana is an herbal extract derived from a South American plant that contains a natural form of caffeine called guaranine, which is noted to be several times stronger than the caffeine found in coffee. Guarana benefits may include enhanced energy, appetite control and possible relief for pain associated with poor joint health. The guarana herb was traditionally consumed as a beverage, with hot water poured over a half-teaspoon of crushed seeds. Guarana is now available in capsule form and can be taken on a short-term basis to boost energy and mental function. Look for guarana supplements in both capsule and liquid form on Vitacost.com.
