I know the proper zinc (picolinate) however I have not seen the proper dosing. Yes I know other zinc preparations have been used, however picolinate is far more bioavailable where it is needed. Zelenko's original prescription was for 220mg zinc sulfate. I got a hold of some zinc gluconate and found something on line about how much zinc is in different formulations.
200mg of zinc sulfate has about 50mg of zinc. The zinc gluconate has about .143mg zinc per mg, so you'd need 350mg to get the same zinc content. I don't recall if the source I read had figures on zinc picolinate.
Of course, how much gets into your system with each of these would make a difference as well. I wonder how much additional zinc is necessary to have therapeutic effect.
Good question. I use
nutricost (finally back in stock and substantially more expensive). 50mg is 50mg.
My question is whether taking Zinc Picolinate has any prophylactic effects? The US diet is poor in zinc, partly because of soil leaching resulting from mono cropping.
Type 2 diabetes as well as other types of metabolic syndrome related disorders are known for low levels of cellular zinc.
Something I have been thinking about.
