Zinc: A key mineral for immunity, skin and fertility

Zinc is an essential trace mineral involved in over 300 enzymatic reactions in the human body. It plays a central role in immunity, wound healing, skin and hair health, and male fertility [1]. Even moderate deficiency can have significant consequences on overall health.

Why is zinc essential?

Zinc contributes to:

• to the normal functioning of the immune system [2]
• to the maintenance of healthy skin , healing and sebum regulation [3]
• to normal fertility in men, particularly through sperm quality [4]
• to the protection of cells against oxidative stress

It is also involved in DNA synthesis, growth, and cell division. Its role in tissue regeneration makes it a supplement of choice in cases of acne or chronic infections [5].

Zinc deficiency: who is affected?

According to EFSA and HAS, the groups at risk of zinc deficiency are:

• the elderly
• pregnant and breastfeeding women
• people suffering from digestive disorders (Crohn's, colitis, etc.)
• strict vegetarians or people with an unbalanced diet [6]

Supplementation and recommended forms

The zinc bisglycinate form is the most bioavailable and best tolerated at the digestive level. It can be combined with vitamin C to strengthen immunity. The recommended daily intake (RDI) varies from 8 to 11 mg depending on gender and age [7].

In the event of a proven deficiency or chronic infection (acne, repeated colds, etc.), a therapeutic dose can go up to 25 mg/day for a few weeks, under medical supervision [8].
