Cholesterol and blood fats
Taurineand LDL cholesterol
Two sources here, and they say different things: one measured lower LDL cholesterol and one found no clear difference.
How sure anyone can be
Low certainty, level 2 of 4Further research is likely to change this.
The most certain of the two findings here; each record carries its own.
The numbers reported
One source’s range, drawn against its own line of no difference and scaled to its own numbers.
-8.35-5.08 mg/dL-1.81
This range stays on one side of the no-difference line.
Two sources, newest first
We do not pick between these or average them into one number.
What we read is the published abstract, not the full paper, so a blank below may still be printed in the paper itself. A fixed rule worked this out from the source’s own fields. Nobody checked this rating by hand.

Imprecision stops at the first check that applies; others may apply too.
AI-reviewed & signed — an AI agent re-read this finding against the saved source and checked that the quote, the numbers, the units and the direction match it. No person read it. The owner authorised the agent to sign the batch with the owner's key, and every build rechecks that signature against these exact bytes.

AI review could not confirm it — an AI agent re-read this finding against the saved source and at least one check failed. The batch record names the check and quotes the sentence that caused the doubt. No person read it.
What is still missing from these readings
- One gives no likely range, so how precise that number is is unknown.
- Two do not say how many people took part.
- For how long — One of Two readings: Not in the abstract.
Something nobody wrote down is never a zero and never a guess.
Still to read for Taurine
One of the nine things on our list for Taurine has no reading here yet:
- Cycling Functional Threshold Power
Still to read means nobody here has got to it, not that it was tried and did nothing or that no research exists. A pairing on no list is not a gap: we never set out to read it.
