HI-Z  - 1 fl. oz. (Chelated Zinc Citrate) Promotes Wound Healing Encourages Clear Complexion Contributes to DNA Synthesis May Improve the Balancing of Blood Sugars Supports Healthy Immune System Aids in Protein Production Zinc is an essential trace element. According to the NIH1, "zinc supplementation may be used to increase immunity against viruses or may interfere with the replication of certain viruses, such as the human papillomavirus (HPV)." As elemental zinc slowly absorbs in the gut, 3rd Rock Essentials' HI-Z is chelated for increased bio-availability. Elemental zinc is found as a metal ion. Zinc citrate is a zinc salt form of citric acid. Since salts (not metals) dissolve in water, the zinc citrate is now able to be more easily absorbed and used by the body. 5 drops of HI-Z provides the equivalent of 11.42 mg of Chelated Zinc citrate. Each bottle contains approximately 600 drops and is about a 4 month supply for one person.  It is advised to not take daily Zinc supplements containing more than 40mg unless monitored under the supervision of your doctor. Infants under 6 months should take less than 4 mg per day. Contains: Chelated Zinc  (as Zinc Citrate)  Other ingredients: Distilled water, citric acid. *This product has not been evaluated by the FDA. It is not meant to diagnose, treat, cure or prevent any disease. **This product has possible interactions with medication.  According to the Mayo Clinic2, interactions can occur with the following: Antibiotics. Oral zinc while taking quinolone or tetracycline antibiotics can interfere with their ability to fight bacteria. Taking the antibiotic two hours before or four to six hours after taking HI-Z can minimize this effect. Penicillamine. Oral zinc with the rheumatoid arthritis drug penicillamine (Cuprimine, Depen) can reduce the drug's ability to ease arthritis symptoms. Taking HI-Z at least two hours before or after taking the drug might minimize this effect. Thiazide diuretics. These blood pressure drugs increase the amount of zinc lost in urine.
