Excerpt from this article:

found that adding five milligrams of zinc Picolinate to the diet

alleviated acrodermatitis enteropathica symptoms, whereas 60 milligrams per

day of zinc sulfate did not.

The research has also shown that the preferred way to increase zinc

absorption is not to add picolinic acid to the diet, but to take zinc

picolinate supplements.

A group at Bastyr College of Naturopathic Medicine in Seattle, WA, compared

zinc picolinate, zinc citrate and zinc gluconate absorption in students, and

published their findings. The study was a double-blind, placebo-controlled,

cross-over clinical trial, and the results showed that red blood cell levels,

blood serum levels, and hair levels of zinc all improved best with zinc

picolinate (the next best was zinc gluconate).

Supplement users, in fact, note that since zinc picolinate is so well

assimilated, the amount needed may be only one-third as much as normally

taken for supplemental purposes.
