Activity of the most studied minerals in Nutritherapy – Zinc



Supplementation studies

– at 12 years => improvement in growth, reduction in respiratory infections, mortality

– improves anti-infectious defenses and greatly reduces mortality in developing countries

– significant reduction in ear infections (-33%)

Intakes are insufficient in more than 80% of the population, 100% in adults and seniors

RDA: 15 mg

The zinc salts shown to be the most bioavailable are zinc citrate and zinc picolinate

To recover a zinc deficit , give twice the RDA (30 mq) for an average of 2 months for children, 3 months for adults, 6 months for seniors – before returning to the RDA (15 mg / d)

> cessation of bacterial or ENT infection and resumption 8 days after the end of the infection

Think about overuse populations:

Like pregnant women – studies show that 100% of them do not have the RDI and that more than 75% of them receive less than 10 mg of zinc per day through the diet, this at the time when we need it most (impact on brain development in utero, overall development, immunity, vulnerability to heavy metals,… we suspect that this lack of zinc increases the risk of dyslexia and other neurobehavioural disorders).

Very increased needs also in children and adolescents in strong growth The lack of zinc reduces the capacities of development, including cerebral and makes it vulnerable to infections. If the growth curve is low, zinc should be the first line intervention.

Importance of zinc in athletes who needlessly stuff themselves with protein, while they lack zinc to build muscle.

Importance of zinc for male fertility (no sperm multiplication without zinc) and role in the metabolization of androgens Studies: experimental zinc deficits lead to a drop in testosterone and spermatogenesis, supplements allow + 385% of pregnancies and + 318% of children born!

Importance of zinc in the reconstitution of tissue: fractures, osteoporosis, sarcopenia (loss of muscle mass in the elderly, but also in people with inflammatory pathologies, chronic infections, cancers, etc.)


1- in diabetes insulin depends on zinc for its conformation

2- co-enzyme of many enzymes (+200) which depend on zinc: including de! Ta6 desaturase essential for the metabolization of essential fatty acids and the production of anti-inflammatory prostaglandins

3- restoration of the digestive barrier: multiplication of enterocytes and probiotics

4- absorption of the polyglutamate form of vitamin B9 (folates)


Oysters, seafood, organic liver, eggs, lean meats and fish (but all animal sources are increasingly polluted – favor organic meats and small fish – seafood is less and less recommendable. – beyond that we consume far too much animal proteins, inflammatory at the expense of vegetable proteins, anti-inflammatory – cf. Less Meat – towards a transition for the benefit of health, the animal world and the environment).

Unfortunately, vegetable zinc is not very bioavailable which leads to recommend the taking of a daily nutritional supplement containing zinc citrate with all compatible minerals (neither iron nor copper), vitamins – recently we added protective active ingredients ( N-acetylcysteine, glutamine, polyphenols, lycopene, lutein…). There is hardly any indication for zinc on its own.

The most complete to date are Physiomance Multi (Thérascience) and Multigenics (Multidyn in France) Senior.




Zinc is the most important mineral for the immune system, but, paradoxically, it can promote bacterial overgrowth during infection

It is therefore necessary to suspend its intake during a bacterial infection (angina, otitis …) and during ENT infections mixed with viral, which are easily the subject of bacterial secondary infections. It can be resumed a week after the end of an infection. On the other hand, zinc has documented antiviral effects. It is therefore given during purely viral infections, without risk of bacterial superinfection.

Iron and copper antagonize the absorption of zinc in supplements (not in animal proteins or in separate protein / fiber niches).

No need to overdose the zinc to bring it back up because it will be blocked in the digestive tract: maximum 2x the RDA is 30 mg, 45 mg in the event of obesity, possibly more in the event of Wilson’s disease or heavy metal poisoning

To correct zinc deficits, you need relatively long corrective cures (2 to 6 months)
