If you are over 35 or overweight, we recommend that you take Liv Pure for at least three to six months so that it has enough time to cleanse your entire body and get you to your desired weight and maintain it for many years to come. If you opt for the discounted package of up to six bottles, shipping is free. Remember that stock is running out fast. All the more reason to buy packs of three or six bottles before the price goes up or we run out completely.
