I agree, and I don’t recommend anyone take zinc before getting their zinc levels tested. Or if they know they have genetic issues with zinc and zinc deficiency.
But the side effects from the zinc could be from a deficiency as well.
If you are low in serotonin and dopamine and take zinc, it will increase these, and since you were low for so long, the reaction to higher levels will be more pronounced. The increase in serotonin is usually what causes stomach upset, and diarrhea.
So it’s probably better for people who haven’t taken zinc who are deficient to start slowly.
