Original title: Taurine as a possible antiaging therapy: A controlled clinical trial on taurine antioxidant activity in women ages 55 to 70.

What the study found

Points to benefit

Blood taurine and an antioxidant enzyme (SOD) rose in the taurine group. Glutathione reductase fell in both groups. Malondialdehyde rose only in the placebo group. Strength and body measures were secondary.

How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • ✓Compared with a placebo, a dummy treatment.
  • –Small: 24 people. Small trials can miss real effects or find chance ones.
  • •Lasted 16 weeks.
  • –Measured lab tests or markers, which stand in for aging and age-related decline. A better marker does not always mean better health.
  • •The PubMed record has no conflict-of-interest statement.
  • •Summarized from the PubMed abstract only. The full paper may hold details the abstract leaves out.

✓ Strength– Limit• Note

These points come from fixed rules about the type of study, its size and length, what it measured, and who has a stake. Every study on Digestery gets the same rules.
