I have been running zinc picolinate for a fortnight and the honest summary is that the effect is smaller than the internet suggests and real.
There is a serious question about whether the studied form matches what is sold, and nobody in a thread can answer it.
What the mineral class does pharmacologically does not require the subjective effect to be large to be real.
Cold storage, light protection, and a date on the vial. Boring, and it removes half the variables.
Curious whether the popular dose has any basis or is just the convenient one.
An inconclusive account is useful if it stops the next person mistaking a story for a controlled comparison. Not on zinc picolinate but the pattern is familiar.
Stupid question: how do you know whether what is in the vial matches the label at all?
Same here.
Same here.
Baseline first. Without a baseline the after picture is decoration.
Same here.
Same here.
Currently on zinc picolinate myself.
Three questions kill most of the confidence in a thread like this: sample size, blinding, who paid.
Nobody has ever been talked out of a stack by a stranger on the internet.
Most of the popular protocol is borrowed from a clinical population and applied to healthy people without comment.
