4 specific benefits of zinc for women

Zinc: a trace element essential to our health

Zinc is an essential mineral, involved in over 300 enzymatic reactions.

In particular, it contributes to the normal synthesis of DNA, the normal functioning of the immune system and the maintenance of normal bone structure.

Zinc is currently being studied for its potential benefits for women, particularly pregnant women, as well as for the menopause, hair, nails and skin.

Recommended daily allowance of zinc

Here is the recommended daily intake of zinc for healthy adults:

• adult women: 8 mg per day (1)
• men: 11 mg per day
• pregnant women: 11 mg per day on average
• breastfeeding women: 12 mg per day

Risks of zinc deficiency and associated symptoms

Common symptoms of zinc deficiency can include fatigue, delayed wound healing, hair loss, brittle nails, reduced immunity and disturbances in sebum production that can lead to acne.

The situations where there is a risk of zinc deficiency in a woman's life are:

• pregnancy and breastfeeding, with increased needs (to be monitored with a doctor)
• the menopause, during which zinc's antioxidant properties play a protective role
• vegetarian diets or diets rich in phytates (found in wholemeal cereals, lentils, pulses and wheat germ), which reduce zinc absorption

4 recognised benefits of zinc for women

1. Zinc and hormones in women: a link with hormone regulation and fertility

Zinc contributes to normal fertility and reproduction. It is thought to play a key role in oocyte maturation and hormone regulation, by participating in the enzymatic processes required for hormone synthesis.

This role is not just theoretical: the discovery of the ‘zinc spark’, a phenomenon in which zinc is released during fertilization, illustrates its possible involvement in the conception process.

A recent study showed that, of several metals studied, zinc is positively associated with the chances of conception, whereas other metals such as copper, cobalt and chromium can have adverse effects on fertility.

Studies indicate that zinc may be able to protect female fertility by reducing the negative impact of certain toxic metals (2).

2. Benefits of zinc for pregnant women: foetal development and maternal immunity

Zinc plays a role in the process of cell division and contributes to the normal synthesis of DNA, which is essential for foetal development.

It also supports the normal functioning of the immune system, participating in the activation of certain enzymes and immune cells, which can reduce the risk of infection for pregnant women.

A meta-analysis shows that zinc supplementation may slightly reduce the risk of premature birth (3).

3. Menopause: bone protection and antioxidant properties

With age, women are exposed to a loss of bone density. Zinc, in synergy with vitamin D, helps maintain normal bone structure and helps protect cells against oxidative stress.

It is thought to play a part in the formation and regulation of the cells responsible for bone renewal (osteoblasts and osteoclasts).

A recent study showed that in post-menopausal women with low bone density, dietary intake and serum levels of zinc, calcium and magnesium were significantly lower than recommended (4).

The researchers emphasise that these mineral deficiencies may play a key role in bone fragility, and recommend targeted supplementation with zinc, calcium and magnesium, possibly combined with copper, to support bone health.

Maintaining a sufficient intake of zinc could therefore help to protect bones and preserve mineral density, as a complement to a healthy lifestyle.

4. Beauty: benefits of zinc for the skin, hair and nails

Zinc helps maintain normal hair, skin and nails.

These effects are explained by zinc's role in protein synthesis and cell division, which are necessary for cell regeneration.

In fact, one study highlights the fact that the skin, which is rich in zinc, depends on this mineral for its proper functioning, and that deficiencies or malfunctions in zinc transporters can lead to skin disorders, hair loss and delayed healing (5).

This explains the presence of zinc in certain beauty cosmetics and food supplements.

Discover the Daily Beauty supplement, rich in zinc, vitamin B8, collagen and keratin.

Keratin, an essential protein in hair and nails, contributes to their strength and growth, complementing the action of zinc.

How can I cover my zinc needs?

Zinc-rich foods

Certain foods are particularly good for providing an adequate supply of zinc:

• oysters: up to 74 mg/100 g, a natural record
• meat (beef, poultry)
• shellfish (crab, lobster)
• wholemeal cereals (such as rye and wheat bread)
• pulses (green lentils, white beans)
• fresh vegetables (spinach, broccoli)
• zinc-rich nuts and seeds: cashew nuts, almonds, pumpkin seeds

Did you know? For vegetarians, the phytates present in legumes and wholemeal cereals can reduce zinc absorption (6). To remedy this, it is advisable to soak or sprout these foods before cooking: a simple gesture that increases the mineral's bioavailability.

Zinc food supplements: the available forms

Zinc food supplements can help cover daily requirements, especially in cases of deficiency or increased needs (pregnancy, menopause, oxidative stress).

Depending on the form used, bioavailability and specific effects may vary.

• Zinc orotate: Zinc is combined with orotate, a compound that may facilitate its passage through the body. This form is known for its high bioavailability, which may help to cover zinc requirements effectively.

Discover the Zinc Orotate supplement, to obtain zinc in its most bioavailable form.

• Zinc L-Carnosine: a combination of zinc and L-Carnosine, this dipeptide may support the digestive mucosa and contribute to intestinal comfort, while helping to protect cells in the intestine.

Discover the Zinc L-Carnosine supplement, a natural combination of L-carnosine and zinc.

• Zinc bisglycinate: zinc is bound to two glycine molecules, making this form gentle on the stomach and relatively easy to assimilate. It may be suitable for those looking for a regular intake that is easy to tolerate.

Discover the Lozenges Advanced Zinc Bisglycinate supplement, appreciated for its optimal bioavailability and tolerance by the body.

• L-OptiZinc®: this patented form combines zinc with an amino acid and may offer improved digestive tolerance and high bioavailability. It is suitable for a regular daily intake.

Discover the L-OptiZinc® supplement, which contains both zinc and L-methionine, a highly assimilated essential amino acid.
