Chelated zinc is considered one of the best forms of zinc supplements due to its high bioavailability in the body. Specific recommended forms of chelated zinc include: - Zinc gluconate; - Zinc citrate; - Zinc picolinate. Other forms of zinc supplements, such as zinc sulfate and zinc acetate, are also available, but they may be less easily absorbed by the body. Before starting any zinc supplementation, it is advisable to consult with a healthcare professional to determine the appropriate dosage and form based on individual needs.
