Wholesale 98% Zinc Picolinate CAS 17949-65-4
What is Zinc Picolinate?
Zinc Picolinate is a highly bioavailable organic zinc compound formed by the chelation of the essential trace element zinc and the organic acid picolinic acid. This structure mimics the body's natural absorption of minerals, allowing zinc to enter the body in a more stable and easily absorbed form. Picolinic acid significantly enhances the bioavailability and absorption rate of zinc in the body, making it more easily absorbed and utilized than many other forms of zinc (such as zinc citrate and zinc gluconate).

Why Choose Zinc Picolinate?
1. High Absorption Rate
Picolinic acid helps zinc ions pass more smoothly through the intestinal absorption barrier, reducing the problem of antagonism or waste during digestion. Multiple studies have shown that it is more efficient at increasing zinc levels in the body than common forms such as zinc citrate and zinc gluconate.
Core Advantages: Faster absorption, higher utilization rate, lower required dosage
2. Comprehensive Health Support
Zinc is an important cofactor for more than 300 enzymes and proteins, participating in multiple metabolic pathways. Zinc supplementation with zinc picolinate can more effectively support:
Immune function: Helps maintain normal immune cell function and defense capabilities
Skin health: Participates in collagen synthesis and tissue repair, supporting skin barrier stability
Men's health: Helps maintain normal prostate function and testosterone metabolism
Antioxidant: Participates in oxidative stress regulation, reducing free radical damage
Cognitive support: Participates in neurotransmitter synthesis, having a positive effect on brain function
3. Safety:
Zinc picolinate has a stable chemical structure and is well-tolerated. At appropriate doses, it is suitable for long-term nutritional supplementation and functional formulation applications.
