Our proprietary plant-based blend combines the powerful benefits of French maritime pine bark extract, antioxidants, and naturally occurring amino acids. The primary ingredients in Ristela, French maritime pine bark extract, arginine, citrulline, and rose hips extract, are collected and shipped to the United States to be made into Ristela tablets. One of the primary ingredients in Ristela, French maritime pine bark extract, is prepared from the bark of pine trees grown exclusively in southwestern France using a standardized process. The multilayered thick outer bark is harvested from 30-year-old trees. Cut trees are then replaced by seedlings, so that the process is completely sustainable. What’s more, this process is monitored by the French government and the majority of the forest is a national park. Rose hips extract originates from the fruit of the wild rose plant. It is a potent antioxidant that contains vitamin C.
