Zinc 15 mg zinc bisglycinate, 100 capsules

Minerals - Best absorbed in chelate or bisglycinate form!

This product contains zinc bisglycinate zinc. In this process each zinc particle is powerfully bound (chelated) to two (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 only genuine amino acid chelates from Albion Minerals, recognisable by the TRAACS® brand, which stands for The Real Amino Acid Chelate System. This brand serves to distinguish them from other amino acid chelates that may be inferior or unstable. Albion holds over 100 patents worldwide that protect the process, the science and the structure of their amino-acid-chelated minerals. Their minerals are also analysed, and every batch produced undergoes quality testing. It must in any case be verified whether chelation has actually occurred and whether the bonds are sufficiently strong.

Advantages of amino-acid-chelated minerals

The structure of an amino acid chelate is robust enough to withstand attack by stomach acid and digestive enzymes (unlike other mineral compounds), yet sufficiently weak to release the mineral element after uptake by the intestinal cells. The amino acids surround the mineral element and protect it during digestion so that it cannot be lost. In addition, the electrical charge of the chelate is neutral, which means it does not bind to food particles in the stomach and intestines. Thus the amino acid chelate reaches the small intestine intact, where it is absorbed as a dipeptide (a compound of two amino acids). This is very advantageous because the body can take up amino acids (especially dipeptides) extremely easily, particularly when they are derived from the smallest amino acid, glycine. Amino-acid-chelated minerals are much better absorbed than other types of minerals. The amino-acid-chelated mineral is taken up by active transport into the mucosal epithelial cells of the jejunum (middle part of the small intestine) without competing with other minerals. Only through metabolic processes in the mucosal cells is the glycine broken down together with the mineral and made available to the various organs and body systems.

Effects of zinc in the body

Because of 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 metalloenzymes that use a zinc ion as a cofactor. It also forms an important part of the structure of proteins and cell membranes. In this way, zinc is involved in numerous processes in the body, such as cell division and hormonal balance. Zinc is also involved in the normal breakdown and synthesis 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, among other things 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 represents one of the crucial buffers that helps keep the acidity of the blood and other extracellular fluids as constant as possible.

Without copper

Zinc and copper are antagonistic to one another. An intake of 50 mg or more of zinc per day over a period of more than one month can lead to low copper levels, which is undesirable. Excess copper is also problematic, especially for older people. Therefore Vitals has deliberately chosen not to combine zinc and copper in this product. It is assumed that it is quite likely that someone will also be taking a daily multivitamin and mineral preparation and thus already consuming additional copper. It is recommended that at a dosage 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 2 products with zinc chelates on offer, Woscha L-OptiZink and Vitals Zinkbisglycinat. Where is the difference?

Zinc chelates, the better zinc

You can't simply take metals like iron or zinc in their pure form. The intestine would be unable to absorb the necessary milligrams of minerals from bits of zinc or iron — that seems logical, even without a degree in biology.
So these must be taken in the form of chemical compounds that the intestine can absorb. In the blood or in the cells the body can then do with the metals what it wants, once it has released them from those compounds.
There are chemical compounds that are better suited and others that are moderately or poorly suited. You can often find this out straight after swallowing the capsule — some quickly cause nausea.
This is especially familiar to people who have to take cheap, low-quality products from the pharmacy because the doctor is not familiar with these differences. With zinc or iron such unlucky people often have this problem.

Among the best compounds are chelates. These generally achieve, firstly, very good uptake in the body and, secondly, avoid side effects such as nausea or intestinal complaints.
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 that contain zinc bisglycinate or L-zinc methionine. These are two different organic zinc compounds in which zinc is bound to different amino acids:

  • Zinc bisglycinate: Here one zinc atom is connected 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 because of its ability to combat free radicals and its good bioavailability in specialised treatments (such as for the skin).

Important differences at a glance

Zinc bisglycinate:

  • Binding partner: Two glycine molecules (the simplest amino acid)
  • Chemical structure: Zinc complex (twofold)
  • Special feature: Very good tolerability, avoids competition with other minerals in the intestine

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 particularly long.

Both are high-quality organic forms of zinc and are absorbed by the body much better than inorganic forms like zinc oxide or zinc sulphate.

Vitals, our new brand from 2025

We are constantly on the lookout for brands that represent our ideals: highest quality, the consistent omission of unnecessary additives such as titanium dioxide or porcine gelatin, excellent value for money and absolute reliability in delivery to us and thus to our customers.
This is very difficult because such companies are extremely rare among the mass of dietary supplement manufacturers now on the market. But we have once again managed to find one with Vitals from the Netherlands!
