Zinc vs. Zinc Picolinate — What's the Difference?

Difference Between Zinc and Zinc Picolinate


Key Differences

Zinc and Zinc Picolinate are terms associated with nutrition and health, but they refer to different things. Zinc is a chemical element with the symbol Zn and atomic number 30. As an essential trace mineral, it plays a crucial role in various physiological functions, including immune system support, wound healing, and DNA synthesis. This mineral is naturally found in foods such as meats, dairy products, nuts, and legumes.
In contrast, Zinc Picolinate is a specific compound where zinc is chelated to picolinic acid. The term "chelated" means that the zinc is bonded to the organic compound, which, in this case, is picolinic acid. This formulation is believed to enhance the body's ability to absorb zinc more efficiently than other forms, making it a popular choice for dietary supplements. The rationale behind this is that picolinic acid aids in the transport of zinc through the small intestine, leading to better absorption rates.
Understanding the difference between Zinc and Zinc Picolinate is essential when considering dietary supplements. While Zinc is the general mineral that our body needs, Zinc Picolinate is a specific form of this mineral designed to increase its bioavailability. Simply put, not all zinc supplements are created equal, and the picolinate form is believed to be among the better-absorbed versions.
Supplementing with Zinc or Zinc Picolinate can be beneficial, especially for those who have a deficiency or are at risk of one. However, it's always advisable to consult with a healthcare professional before starting any supplement. Regardless of the form, zinc plays a vital role in human health, and its adequate intake is paramount.

Zinc Picolinate

A chelated form of the mineral zinc.
Zinc Picolinate is believed to have better bioavailability.


To coat or treat with zinc; galvanize.


A chemical element (symbol Zn) with an atomic number of 30, a slightly brittle blue-silvery metal.


(countable) A single atom of this element.


(Nigeria) A corrugated iron roof.


A zinc countertop.


(rare) To electroplate with zinc.


(rare) To coat with sunblock incorporating zinc oxide.


An abundant element of the magnesium-cadmium group, extracted principally from the minerals zinc blende, smithsonite, calamine, and franklinite, as an easily fusible bluish white metal, which is malleable, especially when heated. It is not easily oxidized in moist air, and hence is used for sheeting, coating galvanized iron, etc. It is used in making brass, britannia, and other alloys, and is also largely consumed in electric batteries.
