Consumer advice
If you have a confirmed or suspected zinc deficiency (vegetarian diet, GI issues, certain medications), this is a reasonably priced, well-dosed option — 25mg is within the standard supplemental range and the picolinate form has some absorption data behind it. Don't take it for "mental clarity" or "mood" expecting dramatic effects; the evidence for those benefits is weak and mostly indirect. Avoid combining with high-dose zinc from other supplements, and don't take long-term without monitoring copper levels, since excess zinc can deplete copper.

Zinc
Zinc from food is unlikely to cause toxicity. High intakes, mostly from supplements, can cause stomach and other symptoms, and doses of 50 mg or more over weeks can interfere with copper absorption. The adult upper limit is 40 mg.
Possible side effects
- High zinc intakes can cause nausea, dizziness, headaches, gastric distress, vomiting, and loss of appetite.
Serious risks
- Doses of 50 mg or more taken for weeks can interfere with copper absorption, reduce immune function, and lower HDL cholesterol.
- Very high supplemental doses (142 mg/day) might interfere with magnesium absorption and disrupt magnesium balance.
- According to a few reports, overuse of zinc-containing denture adhesive creams can lead to neurological symptoms and anemia.
Avoid or ask a doctor first if
- The upper limits don't apply to people receiving zinc for medical treatment, who should be under a physician's care.
- Zinc-free denture adhesive formulations are available to prevent the effects linked to zinc-containing creams.
Medication interactions
- Zinc may interact with quinolone antibiotics, tetracycline antibiotics, and penicillamine.
- Some diuretics can lower serum zinc by increasing zinc excretion in urine.
- People taking medications regularly should discuss their zinc status with their health care providers.
Upper limit: 40 mg a day for adults 19+. This label lists 25 mg elemental zinc.
