Natural source of zinc chelate. This 8 ounce bottle is best taken at 1 teaspoon twice daily. Zinc has a long list of benefits: digestive aid, reproductive organ development, sense of smell improves and many more. This formula comes with a zinc test sheet to see if you really need to take this formula or not. This liquid helps you to heal more quickly and gets you off your herbal programs faster than without taking this liquid mineral. At my practice I test everyone that comes in my door with the liquid zinc test. This product may be interchanged with the Premier Research Labs liquid zinc on your order depending on my stock level. The bottles are the same product and interchangeable and either product will appear in your order. As a practitioner I've discovered that most people will need at least 2 bottles to start with and usually don't need to finish the second bottle. This product can be safely stored out of the sun for several years and you can do the taste test every so often if you feel your health needs a boost. If your body doesn't require this supplement it will taste horrible; not like water, which proves that you need this liquid to speed up healing.
