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.
An average diet will provide about 40â400 mg of taurine per day, but studies have used supplements with up to 400â6,000 mg per day (7, 13). Bottom Line: The main dietary sources of taurine are animal foods such as meat, fish and dairy. Smaller amounts are found in some plant foods. It is also added to many energy drinks.
