Thank you for spelling out the reasoning rather than just the conclusion.

From the other side of the consultation, briefly. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.

Adding a me-too, because a thread of one person's experience is not much use. The detail I would add is minor and it is already implied above.

Moderator note: reminder that nothing in this thread is medical advice, and that clinical claims need a source. Carry on.
