Mafic is an adjective describing a silicate mineral or igneous rock that is rich in magnesium and iron, and is thus a portmanteau of magnesium and ferric. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. Common mafic rocks include basalt, diabase and gabbro.
Other good natural sources of taurine include beef, lamb, dark chicken meat, eggs, most dairy products, seaweed, krill and brewerâs yeast. Raw meat is fairly rich in taurine, comparable to fish, but cooked varieties typically have only 10 milligrams of taurine per ounce. To increase the amount of taurine in your meat, consider eating it rare or medium-rare. Organ meats such as liver and heart contain more taurine than choice cuts of flesh.
Or they may be fed a home-cooked diet, including vegetarian or boiled meat diets, which can also place them at a higher risk of taurine deficiency. Taurine is distributed throughout the body with high concentration in certain tissues including heart wall muscles, in the retina of the eye, and brain.
