Zinc 15 mg zinc bisglycinate, 100 capsules

Minerals – Best absorbed in chelated or bisglycinate form!

This product contains zinc bisglycinate. In this process, each zinc particle is strongly bound (chelated) to two (or up to) molecules of the amino acid glycine.  Such a compound is generally referred to as an amino acid chelate or an amino acid-chelated mineral. The Greek origin of the term ‘chelate’ means something like ‘claw’.

This type of compound was chosen because its bioavailability is particularly high. Vitals uses exclusively genuine amino acid chelates from Albion Minerals, which can be recognised by the TRAACS® brand, standing for The Real Amino Acid Chelate System.  This brand serves to distinguish them from other amino acid chelates, which may be of inferior quality or unstable. Albion holds over 100 patents worldwide that safeguard the process, the science and the structure of its amino acid-chelated minerals .  Furthermore, their minerals are analysed, and every batch produced is quality-tested. It is essential to verify whether chelation has actually taken place and whether the bonds are sufficiently strong.

Benefits of amino acid-chelated minerals

The structure of an amino acid chelate is robust enough to withstand the effects of stomach acid and digestive enzymes (unlike other mineral compounds), yet at the same time weak enough to release the mineral element once it has been absorbed by the intestinal cells.  The amino acids envelop the mineral element and protect it during digestion, so that it cannot escape. Furthermore, the electrical charge of the chelate is neutral, which means that it does not adhere to food in the stomach and gut.  Thus, the amino acid chelate reaches the small intestine intact, where it is absorbed as a dipeptide (a compound consisting of two amino acids).  This is highly beneficial, as the body can absorb amino acids (particularly dipeptides) extremely easily, especially when they consist of the smallest amino acid, glycine. Amino acid-chelated minerals are much more readily absorbed than other types of minerals.  The amino acid-chelated mineral enters the mucous cells of the epithelial tissue of the jejunum (the middle section of the small intestine) via active transport, without competing with other minerals.  It is only through metabolic processes in the mucous cells that the glycine, together with the mineral, is broken down and made available to the various organs and body systems .

The effect of zinc in the body

Due to its extensive and versatile effects, zinc is often used by therapists. Zinc is present in all body tissues and is particularly concentrated in the cell nucleus .  The mineral is essential for the function of over 300 enzymes – the metalloproteins – which use a zinc ion as a cofactor . It also forms a significant part of the structure of proteins and cell membranes.  In this way, zinc is involved in numerous processes within the body, such as cell division and hormonal balance. Zinc also plays a role in the normal synthesis and breakdown of carbohydrates, fats, proteins and DNA.  Zinc has a positive effect on the immune system by supporting T-cell production, promoting the production of cytokines and contributing to the function of natural killer cells .  Zinc protects cells from oxidative damage, partly through its role in the function of the antioxidant enzymes catalase and superoxide dismutase (SOD).  It also helps to maintain a healthy acid-base balance. Zinc acts as a cofactor for carbonic anhydrase, an enzyme that converts carbon dioxide into bicarbonate (and vice versa). Bicarbonate  Bicarbonate is one of the key buffers that helps to keep the acidity of the blood and other extracellular fluids as constant as possible.

Without copper

zinc and copper have an antagonistic relationship with one another. A zinc intake of 50 mg or more per day over a period of more than one month can lead to low copper levels, which is undesirable.  However, excessive copper levels are also problematic, particularly for older people.  Vitals has therefore deliberately chosen not to combine zinc and copper in this product. It is assumed that there is a high probability that a person is also taking a daily multivitamin and mineral supplement and is therefore already consuming additional copper.  It is recommended that, at a dose of 45 mg/day (3 capsules), additional copper be supplemented, ideally at a different time of day to avoid competition for absorption.

Comparison of our two zinc chelates

We have two products containing zinc chelates in our range:Woscha L-OptiZinkandVitals Zinc Bisglycinate. What is the difference?

Zinc chelates: the better form of zinc

You cannot simply absorb metals such as iron or zinc in their pure form. It would be impossible for the gut to extract the necessary milligrams of minerals from tiny particles of zinc or iron – that seems logical, even without a degree in biology.
So you have to consume them in the form of chemical compounds that the gut can absorb. Once in the blood or within the cells, the body can then do whatever it wants with the metals, after it has extracted them from these compounds.
There are chemical compounds that are better suited for this purpose and others that are moderately suitable or less so. You can often tell this immediately after taking the capsule; some quickly lead to nausea.
This is particularly familiar to people who have to take low-quality, cheap supplements from the chemist’s because their doctor is not familiar with these differences. When it comes to zinc or iron, such unlucky individuals often experience this problem.

Chelates are among the best compounds. With these, one generally achieves, firstly, very good absorption by the body and, secondly, avoids side effects such as nausea or gastrointestinal discomfort.
Chelates are compounds of metals or minerals with amino acids.

Zinc bisglycinate and L-zinc methionine

As far as zinc is concerned, we have products containing zinc bisglycinate or L-zinc methionine. These are two different organic zinc compounds in which zinc is bound to different amino acids:

  • Zinc bisglycinate: In this compound, a zinc atom is bound to two glycine molecules. This form is very well absorbed by the body and is particularly gentle on the stomach.
  • L-zinc methionine: In this compound, zinc is bound to the amino acid methionine, which contains sulphur. This variant is often used for its ability to neutralise free radicals and its high bioavailability in specific treatments (such as for the skin).

Key differences at a glance

Zinc bisglycinate:

  • Binding partners: Two glycine molecules (the simplest amino acid)
  • Chemical structure: Zinc complex (double)
  • Special feature: Very good tolerability; avoids competition with other minerals in the gut

L-zinc methionine

  • Binding partner: L-methionine (sulphur-containing amino acid)
  • Chemical structure: Zinc complex (often single)
  • Special feature: Often sold as OptiZinc and is said to remain in the body for a particularly long time.

Both are high-quality organic forms of zinc and are absorbed much more effectively by the body than inorganic forms such as zinc oxide or zinc sulphate.

Vitals, our new brand from 2025

We are constantly on the lookout for brands that represent our ideals: The highest quality, consistent omission of superfluous additives such as titanium dioxide or porcine gelatine, very good value for money and absolute reliability in delivery to us and therefore also to customers.
This is very difficult because such companies are extremely rare among the mass of manufacturers of food supplements that are now on the market. But we have managed to find them again, with Vitals from the Netherlands!

Manufacturer's address: Vitals Voedingssupplementen BV, Pieter Lieftinckweg 29, 1505 HX Zaandam, Netherlands. E-mail: customer service@vitals.eu.
