Table 3 Moderate taurine supplementation studies to date and outcomes
Author | Participants | Dosage (g) | Timing of Dose | Outcomes |
|---|---|---|---|---|
Batitucci 2018 [3] | 14 | 3 | 3 g of pure taurine (capsule) every day in the morning before breakfast, during an eight-week period | No changes in energy expenditure or swimming performance; ↑ in plasma taurine and lactate concentrations |
da Silva et al. [12] | 21 | .5 g·kg body mass/day (~ 4) | One capsule per day for a total of 21 days, beginning 14 days before the eccentric protocol and continuing throughout the 7-day postexercise period | ↑ strength levels and thiol total content; ↓ muscle soreness, LAD level, CK activity, and oxidative damage; Antioxidant enzymes and inflammatory markers, and IL-10 were not altered during the recovery period compared with the placebo group |
Galloway [23] | 7 | First part: 1.66 g. Second part: 5 g/day and 6 g/day of placebo | First part: Seven days of oral taurine (1.66 g) supplementation with breakfast and lunch. Second part: cycled for 2 h after 7 days of placebo ingestion (6 g glucose/day) and again following 7 days of T (5 g/day) | No difference in muscle glycogen or other muscle metabolites between conditions; ↑ the appearance of amino acids following exercise; A 13-fold ↑ increase in plasma taurine concentration; No aerobic effects |
Lee et al. [41] | 24 | 4 | Subjects were randomly divided into 4 groups (n = 6), and given a placebo, taurine (4 g/day), carnitine (4 g/day), or glutamine (4 g/day) tablets for 2 weeks. | ↑ TTE (6.9 min or 9.0 min longer) at 75% of VO2max; ↓ serum Pi concentration measured at all-out state (14% ↓) |
Lim et al. [42] | 14 | ~ 3 | Either cellulose-filled placebo capsules (10 mg/kg body mass; P) or capsules providing 40 mg/kg1 body mass of taurine with 10 mg/kg1 body mass of cellulose (TAU) and drank 250 mL of water one hour prior to testing | In the noncaffeine consumers, taurine resulted in a significant ↓ in maximal voluntary muscle power, ↓ in peak torque, ↓ in first and best power output; taurine ingestion in caffeine-deprived caffeine consumers ↑ maximal voluntary muscle power; no effect on other aspects of contractile performance |
