To maintain robust whole-body health‚ a full complement of essential micronutrients is required. Essential micronutrients – including zinc – can be consumed through foods such as nuts‚ leafy greens‚ and beans‚ as well as in supplement form. Micronutrients offer critical support of the cell cycle and support maintenance of healthy muscle and nerve function. Zinc plays an especially important role in these processes and is required for the healthy function of hundreds of enzymes that facilitate metabolic processes in the body.

The immune system protects the body against pathogens and potentially damaging foreign bodies. When immune dysfunction occurs due to a zinc deficiency‚ restoring healthy levels of zinc can help support and improve healthy cell function. This micronutrient supports both innate and adaptive immunity. To distinguish between cells that are part of the body’s own healthy tissue and from those that are threats against the immune system‚ immune cells communicate with one another. For this communication to be successful‚ the immune cells must have healthy receptors. Ligands‚ which bind to the outside of the receptor and allow it to be activated‚ are critical to this process. Zinc interacts with many ligands to support this cell signaling‚ an important component to healthy immune system function.

Zinc is a critical micronutrient‚ but the type of zinc in supplements can influence the impact on the body. Many zinc supplements on the market are formulated with zinc oxide or zinc carbonate‚ which are poorly absorbed and nearly insoluble. In contrast‚ Liquid Zinc Assay is made with zinc sulfate heptahydrate‚ a hydrated form of zinc sulfate‚ that is water soluble. This highly absorbable form of zinc is designed to provide healthy zinc supplementation.

      I was skeptical

      from MORRISONVILLE NY on 1/12/2020
      The first time I used this product, I tasted NOTHING. It tasted like water. Now, I actually have a strong metallic taste in my mouth when I use it. Same bottle! The "zinc test" actually does work and gives me confidence that the product is effective. I haven't had a cold since I started using it even though it is winter and I work closely with many germ-y children with my job.
