Why Zinc for Dental
Zinc plays a supporting role in dental. 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.
What dose to look for
Clinical studies typically use 15–30 mg of zinc. Common supplement dose; UL is 40 mg/day. Products below this range may not deliver meaningful results.
What form to look for
Avoid zinc oxide — poorly absorbed. Avoid zinc sulfate — lower absorption, may cause nausea. Look for zinc picolinate or zinc bisglycinate for better absorption.
What the research says
Zinc has strong clinical evidence for dental benefits. Meta-analyses of 30+ trials confirm immune benefits; reduces common cold duration by ~33% Learn more
