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.
Contrary to popular belief, taurine is not derived from bullâs testicles although it can be found in the bile of a bull as well as in female cattle. Taurine is also commonly found in food sources such as meat and fish, but is often synthetically made for commercial products like energy drinks and supplements.aurine is safe to consume and can improve the health of those with heart problems and other medical conditions. Those who drink energy drinks with taurine should be aware that the taurine in those drinks may be synthetic and may not offer all of the benefits of taurine found in food sources or in the human body.
