High Dosage Zinc Lozenges with Zinc Acetate
The researchers found that in trials that used less than 75 mg of zinc there were no effects on the duration of the cold. In those trials where more than 75 mg of zinc acetate were used daily there was a 42% decrease in duration of the common cold. When another form of zinc besides zinc acetate was used at over 75 mg there was a reduction by 20% of the duration of the cold.
So when using zinc lozenges make sure to use at least 75 mg per day for successful results. Zinc acetate appears to be more effective than other forms of zinc in helping duration.
You shouldn’t take high dosages of zinc for longer than 7 days. Chronic zinc intake could produce toxicity if taken too long a period of time. In fact if you are taking more than 50mg zinc a day you should take 2 mg of copper to prevent copper deficiency as zinc reduces the level of copper in the body. Intake of more than 100 mg of zinc long term may be immunosuppressive. So we suggest liming the lozenges to one week only.
