What the study found

Points to benefit

Blood taurine rose from 89.2 ± 9.5 μM to 218.0 ± 15.6 μM after 4 weeks; urine taurine rose to 6502.6 ± 380.6 μM, higher than controls. Language and executive scores improved; numbers not given.

How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • –Small: 31 people. Small trials can miss real effects or find chance ones.
  • –Short: 4 weeks. Longer-term effects are unknown.
  • •Measured several kinds of outcomes.
  • •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.
