That is up to you. Some joint care supplements provide ingredients a healthy body already makes and therefore may not be necessary; others may complement the benefits of SierraSil®. Most consumers find SierraSil® provides a sufficient level of benefits that they do not need to take other joint care products. That said SierraSil® alone is not a substitute for healthy living. To compliment SierraSil®’s effectiveness we recommend a diet of wholesome foods, including plenty of fruits, vegetables, whole grains and essential fatty acids. Avoid or reduce highly processed foods. Healthy lifestyle choices include regular exercise, a full night’s rest and reduced stress.
