Size: 8 ounces liquid
Each two teaspoons (10 ml)contain:
  • Zinc (as Zinc Sulfate Monohydrate) 8 mg

Other Ingredients: Zinc sulfate monohydrate in a base of distilled water.

Suggested dose: If your zinc levels are low as dictated by taste reaction (below), take 1 to 4  Tablespoons per day until you notice a change in taste, and then keep testing weekly or daily. This liquid can be used to test zinc levels OR as a zinc supplement.

Since the Zinc Challenge liquid is a bit expensive to take daily at 4+ Tbsp per day, you may take Zinc Supreme capsules (3 per day with meals) instead to increase your zinc levels and then keep testing your levels with Zinc Challenge Liquid.


Zinc Challenge is non-irradiated, food-grade, vegetarian, and safe. It is stored in an opaque, non-reactive container in order to preserve the integrity of this product. This product does not contain wheat, yeast, soy, gluten, eggs, dairy, corn, artificial colors, flavors, sugars, or preservatives.

5 star rating Works Fine 3/27/2013 Zinc Challenge Liquid by Designs For Health (DFH)5
Reviewed by PV Gal from West Lafayette.
The product had no taste for me, which indicates I'm low in Zink. Haven't taken the product for very long, but have been in lots of offices with colds, flu, etc. and I haven't gotten sick. Most of the things this is supposed to help with such as immunity, bone strength, etc. are hard to detect whether it is in fact helping. Time will tell.

5 star rating Great Product!!! 3/22/2010 Zinc Challenge Liquid by Designs For Health (DFH)5
Reviewed by mary from Miami / Fl.
It is an excellent product, easy to consume, and in my personal case I saw the results in a couple of weeks: I had a post-surgical wound for 6 months difficult to heal, and after the use of Zinc 4 tab every day, guess what?: My wound is closed. It is excellent for tissue repair.

5 star rating Great way to test deficiency 8/19/2008 Zinc Challenge Liquid by Designs For Health (DFH)5
Reviewed by Lisa from Tx.
I have read that this test is more efficient than other means of testing. I was very pleased with my purchase.

This is a perfect way to get the Zinc you need without yet another pill. Plus, it''s great to know how much your body needs as you take it!
