A quiet staple for skin, cycles and immunity — and one of the better-evidenced options for hormonal acne.
Zinc is an essential mineral involved in skin repair, immunity and hormone production. For women, it is most useful for hormonal, acne-prone skin and for filling a common dietary gap — especially on plant-based diets, where zinc is harder to absorb.
For correcting a deficiency, and for inflammatory acne, the evidence is reasonably good — zinc has mild anti-androgen and anti-inflammatory effects on skin. It works best when it is filling a shortfall rather than acting as a general tonic. So it is genuinely useful for acne and for women who are low, but not a hormone fix on its own.
Hormonal or inflammatory acne, frequent colds, slow-healing skin, or a plant-based diet (higher deficiency risk).
Oysters are in a league of their own — a few can supply several times a day's zinc. After that, the richest sources are red meat (beef, lamb), other shellfish like crab and mussels, then poultry, cheese and eggs. Plant sources include pumpkin and hemp seeds, cashews, chickpeas, lentils and wholegrains — but these also contain phytates, compounds that bind zinc and cut its absorption, which is exactly why women on a largely plant-based diet are more prone to running low and may need to aim a little higher (soaking, sprouting and fermenting beans and grains improves absorption). This makes zinc one of the minerals vegetarians and vegans should watch most closely — relevant for skin and acne, since a shortfall can show up there first.
A sensible dose is 15–30 mg of elemental zinc per day. Zinc bisglycinate or picolinate absorb well. Stay below 40 mg/day long term unless advised.
Take it in the evening with a little food (it can cause nausea on an empty stomach), away from calcium- or iron-heavy meals, which compete for absorption.
On an empty stomach it can cause nausea. Long-term doses above 40 mg can deplete copper, so add a little copper if using zinc long term.
A small amount of copper (about 10:1 zinc-to-copper) for long-term use, plus magnesium and vitamin D.
Don't take it at the same time as high-dose iron or calcium, or with certain antibiotics — space them apart.
Anyone taking zinc long term (watch copper), and those on antibiotics (timing).
Zinc bisglycinate or picolinate (well-absorbed forms) at 15–30 mg elemental, third-party tested.
Zinc is a quiet staple for skin, cycles and immunity, and worth considering for hormonal acne. Take 15–30 mg in the evening with a little food, and mind the copper balance if you use it long term.
