Collection: Zinc Supplement

Zinc supports immune defense, skin healing, reproductive health, and antioxidant activity. It’s essential for enzymes involved in cell growth, DNA repair, and fighting inflammation. Research shows zinc can shorten cold duration, improve skin barrier function, and aid in wound healing (NIH Office of Dietary Supplements).

While zinc itself doesn’t directly burn fat, studies link zinc deficiency to slower metabolism, increased inflammation, and poor insulin regulation, which can influence weight gain around the midsection. Supplementing zinc may improve insulin sensitivity and support metabolic health, which can indirectly help with weight management (Advances in Nutrition, 2019).

Zinc helps regulate oil production, reduce inflammation, and support collagen synthesis, making it a powerful nutrient for acne, eczema, and wound healing. It also assists in repairing damaged skin tissue and maintaining a strong skin barrier (Dermato-Endocrinology, 2017).

Top zinc‑rich foods include oysters (the highest natural source), red meat, pumpkin seeds, chickpeas, cashews, and whole grains. Animal sources are better absorbed than plant sources due to lower phytate content (NIH).

Zinc is best taken on an empty stomach for optimal absorption, either in the morning or between meals. If it causes stomach discomfort, take it with a small snack. Avoid taking it right before bed if you experience nausea.

Avoid taking zinc with high‑calcium foods/supplements, iron, or coffee at the same time, as they may reduce absorption. If you’re using iron and zinc supplements, take them at separate times unless they’re in a balanced, combined formula (Harvard Health).

Signs of deficiency include frequent infections, slow wound healing, hair thinning, skin issues, poor appetite, and low libido. Blood tests can help confirm deficiency, but symptoms often guide clinical use (Mayo Clinic).

Severe deficiency can cause Acrodermatitis enteropathica, a rare inherited disorder marked by skin lesions, hair loss, and immune dysfunction. In milder forms, chronic low zinc leads to impaired growth, delayed wound healing, and increased infection risk (NIH).

While at‑home zinc taste tests exist, they are not clinically reliable. The most accurate way is a plasma or serum zinc blood test, performed in a lab or under medical supervision.

Yes, taking zinc on an empty stomach or in high doses may cause heartburn, nausea, or a metallic taste. Splitting doses or taking with a light meal can help reduce discomfort (NIH).

Mild digestive issues such as nausea, cramps, or diarrhea can occur, especially with high doses. Stick to the recommended dosage (usually 8–11 mg daily for adults) unless otherwise advised by a practitioner.

This may be related to acid reflux or irritation of the esophagus, often from taking zinc on an empty stomach. If this persists, lower the dose or switch to a different form of zinc (like zinc picolinate or citrate), which may be gentler.
