10 Best ZMA Supplements (With Reviews)

If you work out often, you might have heard of ZMA supplements and their many benefits. To some people, they remain mythical as far as their uses, benefits, and side effects are concerned.

ZMA supplements are among the very best accompaniments for your exercise routine and sleep cycle.

What are ZMA supplements?

ZMA supplements have high amounts of zinc, vitamin B6 and magnesium aspartate. They derive their name from the combination of zinc and magnesium which are the main components of the supplements.

Although this group of supplements is relatively new to the market, it has quickly grown in popularity especially among athletes and others on a consistent exercise regime.

  • Those with sleep disorders also find them quite useful owing to their positive effects on sleep.
  • For athletes, one of the most difficult stages of their exercise routines is recovery.
  • Normally, the body takes a while to recover and be ready for the next exercise routine.
  • ZMA supplements help in reducing the time taken to recover so that one is ready for the next stage of their routine.

When the first batch of ZMA supplements came out, they had a specific formula as far as the amounts and combinations of the primary ingredients goes. Today, however, manufacturers vary the ingredients to match with the specific exercise regime of each athlete, sleep disorder or other issue.

Besides that, some manufacturers add other ingredients for other reasons such as increasing the absorption rate or making the supplements generally better at their work.

Does ZMA work?

The fast rising popularity of this type of supplements is in itself a sign that, indeed, they work as stated by the manufacturers. Even with that, everything needs to be proven by research. To this end, ZMA supplements have proven their worth and usefulness.

The three major ingredients in the supplements in question (zinc, vitamin B6 and magnesium aspartate) were combined to provide the best results as far as recovery from an exercise session is concerned. The same combination works well for sleep deprivation and other issues in the body.

The formula works in this way:

1. Zinc

The first major component of a ZMA supplement is zinc. The body requires zinc for most processes including metabolism and regulation of the work and amount of hormones.

For exercise, zinc is instrumental in the building of muscles.

When you work out, a lot of minerals are lost through being used up and in sweating. Zinc being one of them, you will feel fatigued when you have pushed yourself to the limit. When you take supplements with enough zinc, you will be able to quickly build muscles.

2. Vitamin B6

Also called pyridoxine, vitamin B6 is the other major component in the ZMA formula. Vitamin B6 works by:

  • Maintaining the correct mass of tissues
  • Keeping the muscles lean
  • Repairing the body

When you work out, there are small tears in the muscles. When you take enough of vitamin B6, you will recover faster as it helps in repairing the tears in the muscles.

When you are also fatigued from stress or work, vitamin B6 will help you prevent adding weight and increase the ease with which you fall as sleep.

3. Magnesium aspartate

The work of magnesium in the body is a major one in several ways. First of all, it helps in keeping the working of the muscles at their best levels. That entails all types of muscles including the heart. As you work out, you will push the heart to the limit and that is where magnesium comes in.

Being one of the main minerals tasked with the working of the muscles, magnesium provides you with the best form of endurance. Like zinc, magnesium is lost through being broken down and in sweat. You thus need it after your work out to steady the working of the muscles of the body.

With its work on the muscles, magnesium has a calming effect on the body. Besides shortening your recovery time after a workout, it also helps people sleep peacefully.

4. Other ingredients

The addition of other ingredients in the supplements makes the formula more effective in whatever task you have at hand. Other common ingredients added to the formula include:


Melatonin is a hormone that is also secreted by the body. Melatonin has many roles including solving issues such as:

  • Sleep disorders in the blind
  • Delayed sleep phase syndrome
  • Sleep-wake cycle disturbances
  • Insomnia from beta-blocker drugs
  • Endometriosis
  • High blood pressure
  • Insomnia (primary and secondary insomnia)
  • Jet lag
  • Temporomandibular disorder (jaw pain)
  • Thrombocytopenia (low blood platelets and many others.

Vitamin D3

Vitamin D and its various variants are manufactured by the body when exposed to the sun. Due to its role in the body, it may be needed in supplements. The roles of this family of vitamins include:

  • Maintaining the health of the teeth and bones
  • Regulation of insulin levels hence management of diabetes
  • Aids in the working of the nervous system, brain and immune system
  • A major determinant in the gene expression in the development of cancer
  • Support for cardiovascular health and the function of the lungs

What comes out of the addition of the two ingredients to the ZMA supplements is that you will recover faster after a workout. If you have sleep disorders, you have more ingredients working to help you in doing away with the condition.

While each supplement may have a specific time to take, the general approach is as follows:
