The best ZMA: Our Picks
Guide: Questions you should ask yourself before buying ZMA
What is ZMA?
Zinc, magnesium and vitamin B6 in the form of ZMA improves numerous processes in the body and is responsible for the optimal functioning of our organism.
Zinc is an essential trace element and cannot be produced by the body itself. It must be supplied with food and is consequently involved in numerous metabolic processes.
Zinc is a cell-protecting antioxidant and strengthens the immune system, ensures a balanced acid-base balance and is essential for the growth of skin, hair and nails. In addition, it is involved in the production of testosterone.
Magnesium is a bulk element and fulfils numerous functions in the human body. In particular, it is responsible for the activation of enzymes in energy metabolism and for the functioning of the nerves on the muscles and for muscle contraction.
As a water-soluble vitamin, vitaminB6 is important for enzyme action. It is also involved in numerous processes in the human body. These include: amino acid/protein metabolism, haemoglobin formation and functions in the nervous and immune systems.
What effect does ZMA have in the body?
In addition, a daily intake of 50 mg vitamin B-6 and 200 mg magnesium has been shown to lead to reduced symptoms during menstruation in women.
The sometimes occurring negative accompanying symptoms of menstruation could be reduced. Such symptoms were nervous mood, mood swings, irritability and anxiety. (1)
Zinc enters our body with food and supports testosterone production if the concentration of zinc in the organism is sufficient. A zinc deficiency can limit this and other effects. Such a deficiency can be caused by excessive sweating during sports or an unbalanced diet low in zinc.
Magnesium controls the metabolic processes of potassium, calcium, phosphorus and vitamin C. A deficiency of magnesium can also lead to a deficiency of magnesium. A deficiency of magnesium can also lead to disturbances in these processes. In addition, it controls the function of muscles and nerves and is an important catalyst in the burning of fats.
Magnesium is therefore an important energy supplier. If magnesium is not sufficiently absorbed, the work of muscles and the heart, the strength of bones and teeth, the function of the nervous system, the excitability of muscle and nerve cells, etc. are impaired.
Strictly speaking, vitamin B6 consists of three substances: pyridoxole, pyridoxal and pyridoxamine. It is particularly necessary for the conversion and building of proteins (=protein). It is also needed for the metabolism of the central nervous system and for the formation of haemoglobin (=red blood pigment).
A B6 vitamin preparation is used to treat concentration, learning and sleep disorders and depression. Since vitamin B6 is found in many foods, deficiencies are rare.
According to investigations in a study, it can be assumed that vitamin B-6 has an influence on the deep sleep phase (REM phase). Field reports also describe altered and intensified dreaming. (2)
Symptoms of vitamin B-6 deficiency include acne, fatigue, poor performance, growth disorders and increased susceptibility to infections.
How does ZMA work for better sleep?
Cortisol is our body’s stress hormone. It ensures that our ability to concentrate is not impaired by being awake. On the other hand, our cortisol level must not be too high in the evening so that we can fall asleep better. ZMA brings about exactly this balance throughout the day. A good magnesium supply to the body also increases the quality of sleep.
How does ZMA affect testosterone levels?
Zinc in particular can lead to an increase in testosterone levels. These two factors have a positive influence on muscle function and physique. The importance of testosterone has been studied and confirmed for several years.
It can therefore be assumed that zinc and magnesium lead to accelerated muscle growth with appropriate training. (3)
However, the intake of ZMA does not lead to an increase in testosterone levels if a sufficient amount of zinc is consumed through a balanced diet. However, if not enough zinc is consumed through the diet, ZMA can have an increasing effect on testosterone levels. (4)
Testosterone is an important male sex hormone, also called androgen. It is present in both the male and female organism, but in different concentrations. During puberty, testosterone contributes to the growth of the sexual organs.
In the following table we have listed the most important functions of testosterone in men and women:
|Sex||Function of testosterone|
|Man||Use of voice break, development of broad shoulders and a broad chest, Increasing hair (beard, armpit and pubic hair), Sex-specific prominent chin and broad jaw|
|Woman||Deepening of the voice, growth of the clitoris, increase in body and facial hair (hirsutism), Acne|
The production of the male sex hormone decreases in the male sex with increasing age. The androgen level begins to decrease by about one to two percent per year at around 40 years of age.
A testosterone deficiency is indicated by the following symptoms:
- Decreased sperm count
- Shrinking testicles
Find out in the following video whether taking ZMA as a testosterone booster is necessary to achieve success in training.
For whom is ZMA supplementation suitable?
A deficiency can be determined both by a doctor or by identifying a deficiency on your own. If a deficiency is suspected, a doctor should be consulted for confirmation.
What are the alternatives to ZMA?
Zinc, magnesium and vitamin B6 are available individually in various forms. For example, it is possible to buy magnesium in effervescent tablet form. The disadvantage here is that effervescent tablets cannot be absorbed as well as ZMA because it is bound to amino acids. This ensures better utilisation in the body.
To supplement zinc, it is possible to take zinc tablets. These contain an average of 25 mg of zinc. Vitamin B6 and vitamin B complex preparations are also available in different concentrations and dosage forms as dietary supplements.
Tribulus can also be taken as a testosterone booster instead of ZMA. This is also available in capsule form and contains the extract from plant origin.
The combined effect of zinc, magnesium and vitamin B6 as an “all-rounder” in the right dosage is guaranteed by taking ZMA.
Decision: What types of ZMA are there and which is right for you?
If you want to include ZMA in your diet, you can distinguish between two different types of ZMA:
- ZMA Capsules
- ZMA tablets
Depending on which type you choose to take, you will have different advantages and disadvantages. In order to make the best decision for you, we would like to make your choice easier in the following paragraphs.
What distinguishes ZMA capsules and what are their advantages and disadvantages?
ZMA is mainly available on the market in capsule form. Each capsule contains the optimal concentration of the three ingredients. Therefore, taking the capsules is as practical as it is simple.
It is recommended to take the capsules with enough liquid to make swallowing easier. There is a slight delay in the effect, as the capsule shell must first dissolve in the stomach before the contents can enter the bloodstream to unfold their effect.
What are the advantages and disadvantages of ZMA tablets?
ZMA tablets are ZMA pellets and are taken orally with water. They are automatically suitable for vegans and vegetarians because they do not require a capsule shell.
Due to the given dosage of the tablets, ZMA can be taken easily and practically and can also be taken on the go.
Buying criteria: You can compare and evaluate ZMA based on these factors
In the following we will show you which aspects you can use to decide between the many possible ZMA products.
Here you can see which factors you can use to compare and evaluate different ZMA products:
- Dosage form
- Z-M-A Concentration
- Suitable for vegetarians and vegans
In the following paragraphs we explain in detail what you should look for in the individual criteria.
Form of administration
The form of intake depends on where, when and how you want to take ZMA.
As already mentioned, you can take ZMA in capsule or tablet form. Both are ideal for when you are on the go. You can easily carry them in your bag or gym bag. If required, take the capsule or tablet with sufficient liquid.
If you occasionally forget to take your water, it is advisable to take tablets, as experience has shown that they are easier to swallow due to their size. The tablets can also be dissolved and mixed with a smoothie or protein shake. Simply put the tablet in a blender with the rest of the ingredients.
The ingredients in a capsule or tablet vary depending on the supplier. The main ingredients are usually zinc, magnesium and vitamin B6.
Further additives, which are common due to the production in capsule or tablet form, are listed in the next table.
|Name of ingredients||Ingredients|
|Main ingredients||magnesium oxide, zinc gluconate, pyridoxine hydrocholoride (vitamin B6)|
|Filler||microcrystalline cellulose, dicalcium phosphate|
|Separating agent||magnesium salts of fatty acids|
|Main Ingredients||Magnesium Oxide, Zinc Gluconate, Pyridoxine Hydrocholoride (Vitamin B6)|
|Filler||Microcrystalline Cellulose, Dicalcium Phosphate|
|Glazing Agent||Hydroxylpropyl Methylcellulose, Glycerin, Carnauba Wax|
|Anti Caking Agents||Magnesium Stearate, Silicon Dioxide|
The concentration or the ratio of zinc, magnesium and vitamin B6 varies between the different products.
In the following table you will find the original composition of ZMA, which can help you choose your ZMA product.
|Vitamin B6||10 mg|
Suitability for vegetarians and vegans
ZMA tablets are only suitable for vegans and vegetarians. On the other hand, it is possible that ZMA capsules are made of a gelatine shell and are therefore not vegan.
Don’t worry, there are also many ZMA products that are vegan and therefore made with a capsule shell of plant origin.
Facts worth knowing about ZMA
How should I take ZMA?
It is recommended to take it on an empty stomach before going to bed. The last meal should be about two hours ago. In addition, you should take ZMA about 30 minutes before taking other food supplements.
How do I take ZMA when exercising?
ZMA is an essential supplement, especially for athletes and bodybuilders who train intensively. Large amounts of minerals are excreted from the body, especially through sweating.
During sport, the human body loses a large number of essential minerals through intensive sweating.
When exactly you take ZMA is entirely up to you. Replenishing your zinc, magnesium and vitamin B6 depots is possible and important at any time of day. Since ZMA plays an important role in post-exercise recovery, make sure your stores are filled before your training session.
What are the side effects of ZMA?
Since zinc, magnesium and vitamin B6 are naturally present in the body, side effects are impossible.
If you follow the prescribed dosage on the packaging of the ZMA product, you should not experience any side effects.
Which foods contain ZMA?
Both zinc, magnesium and vitamin B6 can be taken in with food. They are all found in naturally occurring foods.
Foods containing magnesium:
- Wheat bran (550 mg/ 100 g)
- Pumpkin seeds (535 mg/ 100 g)
- Sunflower seeds (420 mg/ 100 g)
- Dark chocolate (290 mg/ 100 g)
- Cashew nuts (270 mg/ 100 g)
Foods containing zinc:
- Oysters (22 mg/ 100 g)
- Liver (6 mg/ 100 g)
- Beef (4.41 mg/ 100 g)
- Cheese (3.8 mg/ 100 g)
- Egg yolk (3.8 mg/ 100 g)
Foods rich in vitamin B6:
- Lobster (1.18 mg/ 100 g)
- Salmon (0,98 mg/ 100 g)
- Sardine (0.97 mg/ 100 g)
- Walnut kernels (0,87 mg/ 100 g)
- Sesame seeds (0.79 mg/100 g)
If you regularly eat enough of these foods, you should not be deficient.
To optimally cover your ZMA daily requirement, you should consume an average of 300 to 400 mg of magnesium, 10 mg of zinc and 1.2 to 1.5 mg of vitamin B6 daily.
How does ZMA work in combination with Tribulus?
Tribulus is one of the best-known testosterone boosters. The combination of ZMA and Tribulus is therefore supposed to have an even more intensive and stronger effect on the so-called “manliness”.
Tribulus and ZMA products in combination are traditionally used to increase libido and hormone production. It is therefore said to cause the production of testosterone when taken in increased amounts. Tribulus is also promoted in the sports sector to increase muscle mass.
