Increase your testosterone naturally with ZMA

ZMA is a patented, natural Zinc-Magnesium formula, which has been shown in clinical studies to increase trained athletes' free testosterone by 33.5% in only 8 weeks, as well as muscular strength by 11.6%.

ZMA supplies both Zinc and Magnesium in their optimal resorption capacity. It contains two highly effective mineral-amino acid compounds: Zinc-L-Monomethionine and double-combined Zinc-Magnesium Aspartate.

Of equal importance to the proper Zinc-Magnesium mixture is the vitamin B6 content, as well as the correct dosage and timing of taking ZMA. All of these factors were taken into account and tested in the development of ZMA.

Why are Zinc and Magnesium so important for athletes?

Zinc improves muscular strength, endurance and muscular growth. It increases the effects of growth hormone and testosterone. Zinc is needed for proper function of the enzymes involved in the reduction of lactic acid (muscle soreness).

A lack of Magnesium, on the other hand, leads to a reduction of oxygen supply to muscle tissue. Magnesium improves muscular strength, endurance and relaxation. It activates enzymes needed for the optimal metabolism of carbohydrates and amino acids.

Why do athletes need higher levels of testosterone?

Testosterone, the male sex hormone, regulates muscle growth. It is produced in the testicles and is the body's most powerful muscle-growing steroidal hormone.

All traits typically associated with male appearance, e.g. muscle mass, broad shoulders, facial hair, low voice, sexual drive, potency, self-assertion, rely on it. Testosterone is the hormone that makes boys become men and distinguishes them from women.

Studies prove that testosterone stimulates protein synthesis and muscle growth and improves recovery times. The more testosterone is produced by the testicles, the more muscle and power you can gain.

Who should use ZMA?

ZMA is suited for men of any age who wish to naturally increase their testosterone levels. It is also ideal for competitive bodybuilders who have blocked their body's natural testosterone production by using steroids and wish to increase it as quickly as possible after such a cycle.

Additionally, ZMA should be taken even while on a steroid cycle as it reduces the likelihood of developing gynecomastia.

Why do athletes often have a lower than usual testosterone level?

1. Overtraining is one of the main causes

If you work out with high intensity your training sessions should not exceed one hour. At that time a sharp increase of the hormone Cortisol forces an equally sharp drop of the testosterone level.

It is estimated that 90% of all bodybuilders, along with many other athletes on intense workout regimens, are overtrained. You can easily recognize this condition by the lack of progress in your workouts.

Advice: Work out hard and intensely but never longer than an hour.

2. Anabolic steroids

If you put substances such as synthetic testosterone or anabolic steroids into your system, your testicles, due to the artificially excessive testosterone level, produce less to none of its own. After discontinuation, it takes months until the body resumes normal production of testosterone.

Many experts have expressed the opinion that that after steroids damage the body's hormonal equilibrium it can never again reach its initial state - the body's own testosterone level forever remains lower than usual.

3. Higher age means lower testosterone level

Men after 35 or 40 years of age find it increasingly harder to gain and maintain muscle mass. Libido and potency decrease as well. The culprit is the steadily sinking testosterone level.

Dr. Ulrich Strunz, in his book Forever young - the success program, notes the following: 'Men have a menopause of their own. After 45, as the testicles produce less of the male sex hormone, the testosterone level in the blood decreases as well. Men lose power, self-assertion, drive and libido. Disruptions in sleep patterns and heat flushes can be signs of male menopause.

4. One-sided nutrition and loss of minerals during exercise

Many athletes stick to a very one-sided diet year-round, consisting mainly of chicken and turkey. These types of meat cannot sufficiently provide the body with the minerals and trace elements essential for proper testosterone production.

On workout days athletes use up to 50% more minerals than non-athletes, as excessive sweating depletes the body of these nutrients.

A Californian laboratory examined over 200,000 people, including thousands of professional athletes with various athletic backgrounds, concerning potential mineral deficiencies. The result: 70% of all tested athletes showed a deficiency in Zinc, as well as, in many cases, Magnesium.

The same test subjects had low testosterone levels. This type of scientific research finally led to the development of ZMA.

Why are Zinc and Magnesium so critical for athletes?

Zinc promotes muscular strength, endurance and growth. It enhances the effects of growth hormone and testosterone. Enzymes that promote the reduction of lactic acid (muscle soreness) require Zinc.

Magnesium deficiency reduces oxygen supply to muscle tissue. Magnesium increases muscle strength, endurance and relaxation. It activates enzymes that are required for the optimal metabolism of carbohydrates and amino acids.

What distinguishes ZMA from regular testosterone-boosters?

As you might know, all previous attempts to increase testosterone production have failed.

Tribulus is no longer a topic as it increases the female hormone estradiol at twice the rate of testosterone. Tribulus is ideal if you want to bring out your feminine side.

Promoting pro-hormones to athletes as an alternative to steroids was a fraud. Prohormones, as the name already suggests, are actual hormones; they are steroids with all their associated side-effects.

ZMA, on the other hand, can be considered a real steroid alternative.

It contains no dangerous hormones and has been proven in two clinical studies with athletes to naturally increase testosterone by 30%. In the 55 to 73 years age group, men were actually able to increase their testosterone levels by 100%.

Is ZMA the key to increased muscle mass and power?

As studies show, Zinc deficiencies can lead to a 40% reduction of androgen receptors and a simultaneous 60% increase in estrogen receptors.

This means that both naturally produced testosterone and artificially delivered steroids require optimal Zinc levels to be effective inside the body. The conversion of testosterone to estrogen inside the liver is also significantly higher when Zinc deficiencies are present.

An increased estrogen level can promote the growth of breast tissue as well as fat gains and excessive water retention. Hence, ZMA is of critical importance to those who strive for building lean muscle mass. It provides Zinc in its most powerful form and optimally saturates the body with this critical mineral.

ZMA could indeed be considered the missing key to rapid muscle gain. It enhances testosterone production, improves its effectiveness and blocks the negative results of estrogen - all this without any side-effects.

ZMA and free-form L-Glutamine form a powerful alliance

As ZMA's ingredients also play a role in the production and release of growth hormone, simultaneous supplementation with free-form L-Glutamine is recommended.

This not only leads to the production of the body's natural testosterone in greater amounts but also enhances the natural release of growth hormone. ZMA and L-Glutamine synergistically enhance each other's effects in this regard.

5 reasons, why NutraSport ZMA is the best ZMA product you can buy:

  1. NutraSport ZMA contains the patented Original ZMA Formula from the USA, which was used and tested in several scientific studies. This is an important difference to most other ZMA products, which only call their product ZMA, but do not use the original patented ZMA formula.

  2. NutraSport ZMA ist guaranteed pure and free from any additives. It contains no colors, fillers or any other substances which could cause allergies in some people.

  3. NutraSport ZMA ist encapsulated in 100% plant based capsules. It is guaranteed free from animal substances and therefore also suitable for vegetarians and vegans.

  4. NutraSport ZMA capsules dissolve immediately after intake and therefore guarantee the immediate absorption of the active ingredients. This is an important advantage compared to ZMA tablets which are manufactured under high pressure and may not dissolve totally.

  5. NutraSport ZMA has a great price/performance ratio, because it only contains the original ZMA, which effect was proven in scientific studies.

For optimum results take 3 capsules daily 30 minutes before bedtime with 1/4 liter water. You should not take other vitamin/mineral products or protein drinks at the same time. Take them about 1-2 hours before ZMA.

Since the ingredients in ZMA are also neccessary for production and release of growth hormone, we recommend to take MegaGlutamin 1500 at the same time to get a synergic effect.
