Each bottle contains a 30 day supply of Cassava Supplement. Cassava is known world wide for its effects on fertility. It helps with increasing the chance of twins, but also with overall fertility. Many women use this supplement to increase fertility even when they're not trying for twins. After taking our concentrated Cassava Supplement your chances of twins can go up by as much as 50%. Cassava Twins has devoted years of science and research to bring you the very best quality of ingredients to make the most potent supplement possible. Cassava works by the same method as prescription fertility drugs, without the side effects. The Cassava plant contains a chemical that causes hyper-ovulation. Natural hormones called GnRH released by Cassava fool the brain into thinking there is insufficient estrogen, causing the brain to naturally release the hormone gonadotropin, dramatically increasing the ovulation rate. Cassava Twins grows a special and specific breed of cassava called 'Ultra Fine Cassava'. Normal cassava, sweet cassava, wild cassava, and other varieties of cassava, do not release GnRH from the body and are not sufficient to increase fertility or chance of twins by more than 2%. We are the only company to grow and use Ultra Fine Cassava no other company has access to it. Other companies use different varieties of cassava that are not useful as fertility aids. Because we grow the Cassava specifically for use in fertility supplements we can make sure it has the highest concentration possible, so that you can get the results you want, fast. Regular varieties of cassava can't come close to the results of our Ultra Fine Cassava. Cassava Twins is dedicated to providing the most effective and purest products possible. Our products are quality tested and hermetically sealed with certificate of analysis approval. Certified cGMP and GMP. Certified Registered Manufacturer.
