Adding the numbers, since they settle part of this. If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way. Most of the apparent contradictions in these threads dissolve at that step.

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

How much of the between-person variation is pharmacokinetic and how much is just adherence measured badly?

Pushing back on stefan_berlin 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.

Agreed, and light exposure is a real but secondary factor. Keep it in the carton; do not build a protocol around it.
