Renew Life's OilSMART is a patented essential fatty acid supplement containing lipase. Lipase is a digestive enzyme, required by the body to break down fats and oils for maximum utilization within the body. OilSMART is formulated to supply the proper ratio of essential fatty acids. OilSMART consists of 3 types of nutritional oils: flax, borage, and fish, which contain the three types of EFAs that the body requires: Omega 3, 6, and 9.Essential fatty acids are called ‘essential’ because they are essential to life. The body cannot produce these oils, so they must be ingested from food sources. However, the main foods that provide EFAs are raw nuts and seeds, and cold water fish. Like water, you need EFAs daily in order to live.
