Clinical Trial Summary

Among the strategies that can improve the body's ability to counteract oxidative stress, the use of nutritional antioxidants has been investigated. Taurine is a "semi-essential" amino acid, also called a nitrogen compound, which has been used as an effective antioxidant due to its ability to neutralize hypochlorous acid, an extremely toxic oxidant produced by leukocytes in the inflammatory process in humans.

Description:

Objective: To evaluate the oxidative parameters of women aged 55 to 70 years after 16 weeks of taurine supplementation. Methods: Twenty-four women age 55 to 70 will be randomly assigned to two groups: control group (GC), supplemented with placebo (1.5 g of starch); and taurine group (GTAU), supplemented with taurine (1.5 g), for 16 weeks. Anthropometry, functional capacity test, taurine, and levels of oxidative stress markers will be determined in pre and post intervention plasma samples. Food consumption will be assessed before, during, and after the intervention. The results will be analyzed by an ANOVA two-way repeated measures mixed model, with the Sidak post hoc (p < 0.05).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in blood oxidative stress marker measurement - Superoxide Dismutase (SOD).	The superoxide dismutase (SOD) activity in erythrocytes was evaluated by the spectrophotometric method, and were calculated at 16 weeks in comparision to the baseline.	sixteen weeks
