Zinc Bisglycinate 15mg by Thorne

If your Zinc, Plasma is low or in the lower end of normal, zinc bisglycinate is a practical daily maintenance dose. It fits vegans and vegetarians with limited zinc-rich foods, people after bariatric surgery, those with celiac or inflammatory bowel disease, and heavy exercisers who lose minerals in sweat. It’s also reasonable if brittle nails, reduced taste or smell, or acne suggest low zinc. For established deficiency, short-term higher dosing is typical, then stepping down to 15 mg.

Zinc bisglycinate is zinc bound to two glycine molecules, which helps absorption and tends to be gentler on the stomach than basic zinc salts. Zinc itself is a cofactor for hundreds of enzymes, including those that build skin barrier proteins and support wound repair. It shapes immune cell signaling and is part of superoxide dismutase (an antioxidant enzyme that neutralizes reactive oxygen). In metabolism, zinc helps the pancreas package and release insulin, which is why low zinc can show up as higher fasting glucose over time.

Take one capsule daily with food as the label suggests. Food reduces the nausea some people get from zinc. This 15 mg zinc bisglycinate is a steady maintenance amount; if your Zinc, Plasma is meaningfully low, clinicians often use higher doses for 4 to 12 weeks, then taper to this range. Pairing zinc with a multivitamin that includes copper helps long-term balance, since zinc and copper share absorption pathways.

Separate zinc by at least 2 hours from iron or calcium supplements, which compete for uptake. Antibiotics in the quinolone class (like ciprofloxacin) and tetracyclines (like doxycycline) bind zinc; take them several hours apart per your prescriber. Penicillamine (for rheumatoid arthritis) is also affected. Long-term high-dose zinc can lower Copper or Ceruloplasmin (copper-carrying protein) levels, so monitor if supplementing beyond maintenance. If you have a known copper disorder, get clinician guidance before adding zinc.
