Taurine is an organic acid which is one of the primary ingredients of bile, found in the lower intestine as well as in small amounts in the tissues. Taurine is an important element as it is required for fat digestion through the emulsification of dietary fats. It is also needed for the absorption of fat-soluble vitamins as well as the control of cholesterol serum levels. Taurine is also needed for the proper use of sodium, calcium and potassium in the body. Cell membrane integrity is also maintained with the help of taurine. Apart from these, research has shown that taurine can be very helpful in managing anxiety, hyperactivity, reduced brain functioning etc. Studies have also revealed that along with zinc, taurine is essential for proper vision. In case of a taurine deficiency there is vision impairment along with problems with fat metabolism, however since the body can synthesize the minimum amount of taurine required, this is a rarity.
