Zinc: The Mineral Women Are Ignoring (And Shouldn't Be)
Zinc does far more than support immunity. It's essential for hormone production, skin health, gut repair, and fertility. Here's how to know if you're deficient.
Zinc is one of the most important minerals in the human body, involved in over 300 enzymatic reactions. Yet it rarely gets the attention it deserves — particularly for women, who are at higher risk of deficiency due to menstruation, pregnancy, and the widespread consumption of phytate-rich plant foods that inhibit zinc absorption.
What zinc does in your body:
Zinc is essential for immune function — it's the mineral your immune cells use to mount a defence against pathogens. It's required for the production of testosterone and progesterone (yes, women need testosterone too — for libido, energy, and muscle tone). It's critical for skin repair and wound healing, which is why zinc deficiency often shows up as acne, slow-healing skin, and stretch marks. It supports gut lining integrity, helping to prevent and repair leaky gut. And it's one of the most important nutrients for fertility and healthy pregnancy.
Signs you may be zinc deficient:
Frequent colds or infections, slow wound healing, acne or skin issues that don't respond to topical treatment, white spots on fingernails, loss of taste or smell, hair thinning, low libido, and poor appetite.

The best dietary sources:
Oysters are by far the richest source — a single oyster provides more zinc than almost any other food. Red meat, pumpkin seeds, cashews, chickpeas, and dark chocolate are also good sources. The challenge for plant-based eaters is that the phytates in legumes and grains bind to zinc and reduce absorption — soaking and sprouting these foods helps significantly.
On supplementation: Zinc picolinate is the most bioavailable form. Take it with food to avoid nausea, and avoid taking it at the same time as iron supplements (they compete for absorption). Note that high-dose zinc supplementation above 40mg daily long-term can deplete copper — if supplementing long-term, consider a zinc-copper balanced formula.
