Key Health Benefits

  1. Overall Well-being: Liquid Zinc Ultra is a highly absorbable liquid supplement that encourages overall well-being. Zinc plays a vital role in maintaining robust whole-body health, supporting the cell cycle, and facilitating metabolic processes in the body. By providing a reliable source of zinc, Liquid Zinc Ultra promotes optimal health and functioning.

  2. Healthy Immune System Function: Zinc is essential for a healthy immune system. When the body lacks sufficient zinc, immune dysfunction can occur, compromising the body's ability to defend against pathogens and foreign bodies. Liquid Zinc Ultra supports and improves healthy cell function, enabling the immune system to respond effectively to threats. It supports both innate and adaptive immunity, facilitating successful communication and signaling between immune cells.

  3. Promotes Healthy Mood: Zinc is involved in the regulation of neurotransmitters in the brain, including serotonin, which plays a key role in mood regulation. Adequate levels of zinc are necessary for maintaining a healthy mood and emotional well-being. Liquid Zinc Ultra provides the necessary zinc supplementation to support a balanced mood and emotional stability.

  4. Support for Highly Active Athletes: Highly active athletes often experience increased zinc requirements due to the demands placed on their bodies during intense physical training. Liquid Zinc Ultra is particularly beneficial for athletes with stressed zinc levels. By replenishing zinc stores, this supplement supports the overall well-being and performance of highly active individuals.

  5. Rapid Analysis of Zinc Status: Liquid Zinc Ultra is excellent for use in the rapid analysis of zinc status. By holding a teaspoon of Liquid Zinc Ultra in the mouth for 15 seconds, one can assess their perception of taste. Immediate taste perception indicates an adequate zinc status, while a lack of taste or delayed taste perception may indicate a zinc deficiency. This feature allows for quick and convenient evaluation of zinc levels.

Technical Bulletin


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.
