Trial in healthy men and in rats: taurine raised blood vessel repair cell colonies

Katakawa and colleagues · Hypertension research : official journal of the Japanese Society of Hypertension · 2016

Original title: Taurine and magnesium supplementation enhances the function of endothelial progenitor cells through antioxidation in healthy men and spontaneously hypertensive rats.

What the study found

Points to benefit

Taurine increased blood vessel repair cell colonies and lowered free radical levels and TBARS scores in healthy men and in rats. Authors suggest this may prolong lifespan by preventing heart disease.

How much this study counts

  • –Not randomized: the groups may differ in ways that affect the result.
  • •The abstract does not say how many people took part.
  • –Short: 2 weeks. Longer-term effects are unknown.
  • –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.
