Animal study

In mice, blood taurine did not clearly change with age, unlike glucose and lactate

Jankowski and colleagues · Cell metabolism · 2025

Original title: Aged mice exhibit widespread metabolic changes but preserved major fluxes.

What the study found

No difference

Glucose, lactate, 3-hydroxybutyrate and many amino acids changed in concentration with age, but notably not taurine.

How much this study counts

  • –Done in animals. Results in animals often do not carry over to people.
  • –Company stake: Senior author reports stock, advisor and founder ties to several biotech and drug companies; none named as taurine sellers.
  • •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.
