Zhang M, Bi LF, Fang JH, et al. Beneficial effects of taurine on serum lipids in overweight or obese non-diabetic subjects. Amino acids. Jun 2004;26(3):267-271.
Thirty volunteers (ages 20.3 +/-1.7 years) with a body mass index (BMI) >/=25.0 kg/m(2), with no evidence of diabetes mellitus were randomized to receive 3 g taurine or placebo orally, once a day for 7 weeks. Levels of triacylglycerol (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and plasma glucose were measured before and after supplementation. The atherogenic index (AI) was calculated as (TC-HDL-C)/HDL-C. The researchers did not observe any differences in baseline parameters between the two groups. But taurine supplementation significantly reduced the TG content and AI. There was also a significant reduction in body weight in those who took taurine.
Taurine exerts beneficial effects on lipid metabolism and may play a role in preventing cardiovascular disease. But larger studies are needed to confirm such effects.
Balshaw TG, Bampouras TM, Barry TJ, et al. The effect of acute taurine ingestion on 3-km running performance in trained middle-distance runners.Amino acids. Feb 2013;44(2):555-561.
In this study, 8 male middle-distance runners were randomized to receive 1,000 mg taurine capsule or a placebo orally. This was followed by a 2-h ingestion period at the end of which participants commenced a maximal simulated 3KTT on a treadmill. After a washout period of one week, participants in the taurine group were switched to placebo and those in the placebo group received taurine. A 3KTT was conducted followed by a 2 h ingestion period as before. The capillary blood lactate level was measured pre- and post-3KTT. Expired gas, heart rate (HR), ratings of perceived exertion (RPE), and split times were measured at 500-m intervals during the 3KTT. The authors reported a significant improvement in 3KTT performance (TA 646.6 ± 52.8 s and PL 658.5 ± 58.2 s) (p = 0.013) with ingestion of taurine. Further studies are needed to determine the mechanisms by which taurine improves performance.
