How Zinc supports dental
For dental support, Zinc is a supporting ingredient backed by research. Involved in over 300 enzymes and critical for immune function, wound healing, protein synthesis, and DNA repair. Zinc picolinate and zinc bisglycinate are the best-absorbed supplemental forms, while zinc oxide has poor bioavailability.
Effective dosing
Most evidence supports 15–30 mg of zinc daily. Common supplement dose; UL is 40 mg/day. Products below this range may not deliver meaningful results.
Form and bioavailability
Avoid zinc oxide — poorly absorbed. Avoid zinc sulfate — lower absorption, may cause nausea. Look for zinc picolinate or zinc bisglycinate for better absorption.
Clinical research
Zinc has strong clinical evidence for dental benefits. Meta-analyses of 30+ trials confirm immune benefits; reduces common cold duration by ~33% Learn more
