Zinc is a crucial mineral that plays a significant role in our overall physical and mental health. It is essential for the proper functioning of reproductive organs and is involved in basic cellular functions. Additionally, zinc boosts the immune system and helps prevent common skin conditions. It serves as a cofactor for over 300 enzymes, enhancing many fundamental chemical processes in the body.
Types of Zinc
Zinc is not easily absorbed by the body unless it is attached to another substance. Therefore, many manufacturers “chelate” zinc to amino acids. Zinc supplements are also available in inorganic, non-chelated forms, commonly referred to as zinc sulfate or zinc oxide.
Chelated Zinc
Chelated zinc undergoes a process called chelation, where organic molecules are electrically charged to attract the zinc mineral. This increases the mineral’s concentration within the molecule, theoretically enhancing absorption by the body. However, Dr. Gabe Mirkin from Baylor University School of Medicine suggests that chelation has a minimal effect on absorption compared to the digestive system’s general conditions.
Zinc Orotate
Zinc orotate is chelated to orotic acid and is easily absorbed by the body’s cellular membranes. Research by Dr. Hans Nieper indicates that orotate forms of zinc are more neutrally charged, allowing them to pass through cell membranes more efficiently, resulting in higher tissue concentrations of zinc. Zinc orotates also have antioxidant properties that protect health while offering highly absorbable zinc.
Zinc Picolinate
This form of zinc is chelated to picolinic acid, aiding its absorption in the body.
Zinc Gluconate
Zinc gluconate, one of the most popular dietary zinc forms, is produced by fermenting glucose. It has a long shelf life but is essentially a chemical substitute for natural zinc. The body absorbs very little of this processed form, as its bioavailability is nearly nonexistent.
Zinc Acetate
Zinc acetate is a chemically altered form of zinc, created by adding acetic acid to zinc carbonate or zinc metal. Known also as zinc salt dihydrate and zinc diacetate, it is considered more absorbable than gluconate. While it can help reduce the duration of the common cold and provide relief for Wilson’s disease, a genetic disorder causing toxic copper levels, it is not highly recommended.
Zinc Oxide
This inorganic compound is commonly used in topical ointments for minor skin conditions like burns and irritation. It is also a frequent ingredient in sunscreens. As a non-chelated, inorganic form of zinc, its absorption and metabolism by the body are inconsistent.
Zinc Sulfate
Zinc sulfate is water-soluble and non-chelated. Like zinc oxide, the body’s ability to absorb and metabolize it varies.
Taking a Zinc Supplement
Zinc is vital for human health, offering numerous benefits such as boosting the immune system and increasing testosterone levels. Various types of zinc supplements are available, but for optimal absorption, I recommend a product that contains plant-based zinc, such as Global Healing’s liquid Zinc.
Natural plant-based zinc is chelated to natural elements, enhancing the body’s ability to absorb it as it would from food sources.
