Zinc picolinate is the zinc salt of picolic acid. Studies have demonstrated that zinc picolinate is more bioavailable than other zinc compounds. While zinc picolinate does not have the highest zinc content of all the zinc compounds, it is considered an easily absorbed form (compared with zinc gluconate and zinc citrate). The most popular applications for zinc is in 'beauty from within', testostesterone 'boosters' and immune health products, but there are a long list of health claims authorised for zinc.
Dose
The reference intake (RI) for zinc is 10mg
The zinc content of zinc picolinate is 20-23%; therefore 50mg of zinc picolinate would be required to obtain 100% of the RI for zinc.
Data on the toxicity of zinc picolinate are limited.
The upper limit for zinc (adults) is 25mg/day.
The Department of Health advises that long term intake of >25mg/day of zinc may lead to anaemia.
