7 Common Types of Zinc Explained

Zinc is an essential mineral contributing to our total physical and mental well-being. It is a key player in the optimal functioning of the reproductive organs, and an important element involved in basic cellular function. Zinc also aids to strengthen the human immune system and deter common skin conditions. It acts as a cofactor with more than 300 different enzymes, boosting the functioning of many of the body’s most basic chemical processes.

Types of Zinc

Zinc is not easily absorbed in the body unless first attached to another substance. For this reason, many zinc manufacturers have “chelated” zinc to organic and amino acids. Supplemental zinc is also available in what is called inorganic form, and is provided as a non-chelated type, usually called zinc sulfate or zinc oxide. Research studies on these forms of zinc show mixed results as whether they are beneficial to the human body.


1) Chelated Zinc:

This form of zinc has undergone a process called chelation, whereby the organic molecules have been given an electrical charge that allows them to positively attract the charged mineral (in this case zinc). This creates a temporary increase in the complexity and concentration of the mineral within the molecule.

In other words, each molecule packs more concentrations of zinc via a process of attaching the mineral to something else, such as an amino acid. The belief is that this helps the body better absorb the mineral. There is much debate as to whether the process actually increases absorption. Dr. Gabe Mirkin from the Baylor University School of Medicine feels that chelating minerals has an insignificant effect on absorption when compared to the general conditions in the digestive system.

2) Zinc Orotate (best form):

Zinc that has been chelated to orotic acid. This type of zinc is most readily absorbed by the human body’s cellular membranes. Research from Dr. Hans Nieper has found that orotate forms of zinc were more neutrally charged, as compared to other types of zinc. This allowed them to pass through the membranes of cells easily, and thus offered the highest amounts of accompanying mineral atoms into the cells, leading to higher tissue concentrations of zinc. Zinc orotates contain many antioxidant properties that can help protect your health, while offering your cells the most readily-absorbable form of zinc on the market today.

3) Zinc Picolinate:

A form of zinc that has been chelated to picolinic amino acids.


4) Zinc Gluconate:

One of the most popular forms of dietary zinc, zinc gluconates are created by a process of industrial manufacturing. This process essentially ferments a glucose, offering a supplemental product with an extremely long shelf-life. Unfortunately, gluconate supplements are just a chemical substitute for actual zinc.

Sadly, the body absorbs very little of this processed form, as the bio-availability of these chemicals is virtually none.

5) Zinc Acetate:

Another chemically-altered form of zinc, acetates are considered to be more absorbable than glutconates. This form of zinc, also known as zinc salt dihydrate and zinc diacetate, is created by adding acetic acid to zinc carbonate or zinc metal. I would not recommend this form of zinc although scientific studies do show that this form can aid in reducing the duration of the common cold, as well as offer treatment for Wilson’s disease, a genetic disorder whereby the body stores toxic levels of copper.

6) Zinc Oxide:

This inorganic compound of zinc is most commonly used in topical ointments for treating minor skin conditions such as burns and irritation. It is also a common ingredient in sunscreens. This type is a non-chelated, inorganic form of zinc. Studies show mixed results on the body’s ability to absorb and metabolize this form of inorganic zinc.

7) Zinc Sulfate:

Water-soluble and non-chelated, this is an inorganic form of zinc. Studies show mixed results on the body’s ability to absorb and metabolize this form of zinc.

Zinc Supplement

Taking a Zinc Supplement

As you can see, there are many types of zinc. For supplementation, I would only recommend zinc orotate because it is neutrally charged, and is able to pass through the membranes of cells easily. I personally use this zinc supplement and have recommended it for years with great results. This form will provide the most health benefits to your body and help you fight off a zinc deficiency.

    Before, I was made to believe that zinc is bad to the body but the zinc that are getting into your body are from the foods you eat. Taking a zinc supplement can be a good option despite others claim that it is harmful if taken internally.

    Wow! I knew that zinc was a little rough on your body, but I didn’t realize there were so many options! I’ve found, personally, that my body takes zinc better when it’s tied to magnesium….
