If you’re over 35 or have excess weight, we recommend taking Puravive for at least 3 to 6 months. This allows enough time for it to work throughout your body, targeting low brown adipose tissue, helping you reach your desired weight, and maintaining it long-term. Each 3-bottle package of Puravive includes 2 bonus books for free. Or, make a smart choice with the discounted 6-bottle package, which also comes with 2 free bonus books and free shipping.
