Same experience, arrived at from the opposite direction. The detail I would add is minor and it is already implied above.

Coming at NurseAsh_DET’s question from a different direction. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

The figures, for anyone assembling their own picture. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

Happy to go further on any of that.

Following on from NurseAsh_DET — and this may be the naive question:

How long did you give it before you decided it was working?

Pushing back on josh_phd_bmore here. Pushing back on the anecdote-stacking. Twenty people reporting the same thing is twenty samples from the same self-selected pool, not twenty independent confirmations.
