Herbal zinc supplements

In herbal medicine, a good zinc supplement is pollen. Pollen is a sticky, yellowish powder found on flowers. It represents the fertilizing element of plants and is very rich in elements essential to life. Each pollen is unique in the world and characterizes only one species of flower. 

Pollen contains many mineral salts and among these zinc is present in considerable quantities. Pollen is not easy to assimilate. There are, however, herbal products that they use micronized pollen, ie suitably treated in order to obtain the physical breakage of the external envelopes of the pollen grain and therefore make the precious nutritional contents that compose it immediately available for digestion.

This results in a better bioavailability than the classic pollen in granules (the one assembled by bees), which quantitatively more is needed to obtain the same nutritional benefits. This is especially important if you choose the compress as an integrative form, as micronization makes the difference. Allergy sufferers must be very careful in taking this supplement.

 

Commercially available zinc supplements

Zinc supplements are available in different types and shapes, such as tablets, ampoules, capsules. The Zinc chelate is one of the most effective and easily absorbed zinc supplements. In most of the supplements available on the market, however, we find very often zinc in association with other elements that assist him in his function, let's see what they are:


  • Zinc-magnesium: supplement of zinc and magnesium and vitamin B6, called ZMA, which is used in particular by those who practice boybuilding, as it seems to increase the production of testosterone and IGF-1, a hormone produced by the liver with anabolic properties.
  • Zinc-selenium: which have antioxidant action.
  • Zinc-vitamin B6: association useful for regulating mood, through the production of serotonin. With the addition of tryptophan, these supplements regulate the production of melatonin and are a valid remedy for insomnia.
  • Zinc-arginine: useful in male infertility.
  • Zinc-vitamin C: has antiviral function against cold viruses. 

Abuse of zinc can cause nausea, vomiting and diarrhea, as well as lowering the level of HDL or good cholesterol.


  • Antibiotics, such as tetracyclines, which inhibit the absorption of zinc in the digestive system.
  • Penicillamine, as zinc reduces the absorption of penicillamine, which is used by people with rheumatoid arthritis, however, taking zinc supplements two hours before or after taking penicillamine solves the problem.

 

Daily requirement of zinc

The average daily requirement of zinc, indicated for the maintenance of a state of good health, is equal to 18 mg for the adult man and 15 mg for the woman.

A balanced diet allows you to introduce about 10-15 mg of zinc every day, sufficient for the needs of the body. A slight deficiency of this mineral can occur due to monotonous diets and low in animal proteins, and manifests itself with symptoms such as fatigue, delayed healing of wounds, greater ease of contracting diseases, reduced sense of taste and smell.

A more severe deficiency causes loss of appetite, delayed growth and sexual development, severe dermatitis, memory and behavioral disturbances. The body needs a greater quantity of zinc in some particular conditions, such as:

  • Pregnancy and breastfeeding (newborns get about 80% of the zinc present in breast milk).
  • Childhood and adolescence.
  • Chronic infectious diseases
  • Alcoholics, 30-50 percent of which have low zinc levels as alcohol decreases zinc absorption and increases urinary secretion instead.
  • Slow healing wounds.
  • People with sickle cell anemia, however, the reason is not yet known, but in fact 44 percent of children, and 60 percent of adults with sickle cell anemia have low zinc levels; People who use high doses of iron supplements, as iron can interfere with zinc absorption, but to reduce this effect, iron supplements are taken between meals to allow time for zinc to be absorbed.
  • A pharmacological supplementation of zinc is indicated in case of strict vegetarian diets, as the bioavailability of zinc is very high in meats, and it is also more easily assimilated. In addition, legumes and whole grains contain many phytates, which bind zinc and inhibit its absorption in the digestive system.
  • People who take diuretics, which can increase zinc excretion by about 60 percent, and in the long run reduce the body's zinc stores.

However, it is also good to pay attention to excess zinc, which can lead to various ailments such as nausea, dizziness and drowsiness.
