Difference Between Zinc and Zinc Picolinate

Zinc and Zinc Picolinate: The main difference between zinc picolinate and zinc is that zinc picolinate refers to the zinc salt of the picolinic acid. Zinc picolinate is also one of the most popular forms of zinc supplements.

Zinc has the chemical Zn with atomic number 30, and is a chemical element. This element has many uses, including as an anti-corrosion agent, a battery component, an alloying material, and more. It is also a major component of many dietary supplements. Zinc picolinate, for example, is a form we use to supplement our diet. We will now discuss the differences between zinc and its picolinate.

Short Definition of Zinc and Zinc Picolinate

Zinc (Zn), with an atomic number of 30, can often be found in nature. Zinc plays an essential role in human health and biological processes involving immunity, wound healing, DNA synthesis, and cell division – essential functions that benefit everyone!

Zinc picolinate is an easily absorbed form of zinc produced by combining picolinic acid and natural zinc compounds. As a food supplement, this mixture can provide bioavailable zinc that’s easily absorbed by your body.

Picolinic acid is often preferred to other zinc supplements due to its increased bioavailability; this allows more effective maintenance or correction of deficiency due to increased intestinal absorption of zinc.

Zinc picolinate supplements are commonly taken to aid immune function, improve skin health, heal wounds quickly, and support reproductive and overall health. But too much zinc can be toxic; to stay safe always consult your physician first before taking supplements and follow his/her recommended dosages.
