Zinc dosage and Primal Defense dosage

[Guest guest]

Hi all,

I have two questions. I would like to try zinc for my son, who grinds

his teeth and chews his fingers, as I heard this could be a sign of

zinc deficiency. What is the upper limit for zinc? The second

question is regarding Primal Defense. My son has been taking different

probiotics for awhile, which are helping somewhat, but I wanted to try

Primal Defense. What is the usual dosage for children? The product

only states an adult dosage. My son is 6 years old and weighs just

under 50 pounds.

Thank you so much!
