Zinc Sulfate

Zinc is essential for keeping the immune system strong, which is why a daily dose of Zinc Sulfate Solution (2.3 mg) may aid in preventing colds and flus. It is also a wonderful test to see if you are zinc deficient Swish around in your mouth for 10-15 seconds and then swallow. If it tastes like water, you are zinc deficient. If a pronounced chalky or metallic taste, your zinc level is fine.

For daily maintenance, one dose should be sufficient. If you feel something coming on, double your dosage and spread it out during the day. If you have a cold or the flu, you can take up to 3 doses and spread it throughout the day.
