Seven zinc-containing dietary supplements were analyzed for zinc (Zn)

and cadmium (Cd) by inductively coupled plasma/mass spectrometry

(ICP/MS). Cadmium was detected in all samples; however, the amount of

Cd per 15 mg Zn (the daily US Recommended Dietary Allowance) varied by

over 37-fold (0.039 to 1.46 micrograms Cd/15 mg Zn). Supplements with

Zn in the form of a gluconate consistently contained the lowest

amounts of Cd. Because Cd is a non-essential potentially toxic element

for humans, its concentration in nutritional supplements should be

minimized and possibly regulated by government-established standards.

.......

This is from 2001. It seems zinc supplements are

contaminated with cadmium. Zinc gluconate contains

the lowest amount of contamination.

I will buy zinc gluconate in the future and no

zinc orotate or other forms.

Hope this is helpful for anybody.
