About this study

Official title: Taurine as a Possible Anti-aging Therapy? A Controlled Clinical Trial on Taurine Antioxidant Activity in Women Aged 55 to 70 Years

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.

Read the detailed 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).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: sixteen weeks

  2. Change from baseline in blood oxidative stress marker measurement - Glutathione reductase (GR).

    Glutathione reductase (GR) activity was determined by the spectrophotometric method at 37 ºC/340nm after the oxidation of NADPH in the presence of oxidized glutathione, and were calculated at 16 weeks in comparision to the baseline.

    Measured: sixteen weeks

  3. Change from baseline in blood oxidative stress marker measurement - Malondialdehyde (MDA).

    The malondialdehyde (MDA) were calculated at 16 weeks in comparision to the baseline.

    Measured: sixteen weeks
