How Zinc supports general health
Zinc plays a supporting role in general health. 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.
How much zinc do you need
Research points to 15–30 mg as the effective range for zinc. Common supplement dose; UL is 40 mg/day. Lower doses may provide some benefit, but most studies showing clear results used this range.
Which form absorbs best
Avoid zinc oxide — poorly absorbed. Avoid zinc sulfate — lower absorption, may cause nausea. The most bioavailable options are zinc picolinate or zinc bisglycinate.
