These benefits occurred in the ZMA group despite the fact that the analyses of their diets found that the athletes were all consuming well over the recommended intake for zinc. In addition to the study performed by the Western Washington University researcher, several other studies have also found that zinc and magnesium offer potent anabolic properties. A study from Selcuk University Konya, Turkey reported that four weeks of zinc supplementation in men increased testosterone levels at rest and after exercise.
Researchers from the USDA reported that zinc depletion decreased muscle endurance in subjects. This means that maintaining optimal zinc levels is critical for your ability to complete a number of reps with a given weight. The same Western Washington University research team that did the ZMA research also discovered in an earlier study that when subjects supplemented with magnesium while following a 7-week leg training program, their leg strength increased by percent more than those taking a placebo.
Both zinc and magnesium are also suggested to blunt cortisol, a catabolic hormone. German researchers found that triathletes taking a magnesium supplement for four weeks maintained healthy cortisol levels at rest and after a triathlon, as compared to athletes taking a placebo. And Brazilian researchers also reported that subjects supplementing with zinc maintained healthy cortisol balance. ZMA may also boost growth hormone GH levels, albeit indirectly.
ZMA enhances sleep quality due to magnesium's ability to normalize and extend stage 3 and stage 4 slow-wave sleep. This is critical, as deeper sleep can help to raise GH levels, which peak during the night. Zinc is also critical for maintaining thyroid hormone production. This is important for keeping your metabolic rate the amount of calories you burn each day and fat-burning capabilities up.
Being low in zinc can limit thyroid hormone production, and compromised thyroid hormone function results in a lower metabolic rate, which makes it harder to drop body fat. Research confirms that when your diet is low in zinc, thyroid hormone levels fall and resting metabolic rate drops.
One study from the University of Massachusetts Amherst found that subjects placed on a low-zinc diet had significantly lowered metabolic rates. When the subjects took 25 mg of zinc each day for 20 days, their metabolic rate jumped up to levels that were higher than even before they followed the low-zinc diet. It appears that zinc is not only critical for thyroid function, but also for maintaining levels of the hormone leptin. This hormone is also important for keeping your metabolic rate high as well as keeping hunger down.
Being deficient in zinc has been shown to significantly lower leptin levels. It is well established that zinc is critical for immune function. Zinc affects multiple aspects of the immune system. Research from the Cleveland Clinic suggests that supplementing with zinc helps to support a strong immune system. Zinc also functions as a powerful antioxidant. This mighty mineral activates an enzyme that may help support overall health and immune function.
Zinc's immune-boosting effects can help to keep you healthy and in the gym. Average heart rate: 15bpm lower than normal HR. The results speak for themselves. This product works. I love these tablets, i received them as a free gift during an offer and have been purchasing them ever since.
I generally have problems nodding off but with 2 of these im able to relax and get a good night sleep. In the morning i generally feel good, although sometimes i have felt even more lethargic but that could be due to anything. I feel like they have aided in recovery, also studies show this supplement help to keep test levels at a constant natural high in your body. Only issue i have is the morning wood, can be dangerous for loved ones in bed with you, bruised legs and what not.
These used to be far more effective. Alot less now. Seems myprotein have changed the ingredients to cheaper alternatives of magnesium and zinc, but have increased their price of these Very misleading reviews also which are very old - when these had better ingredients. I will look for an alternative website next time I want ZMA. Superb item, never ever slept better I fall asleep easily and wake up rested.
Goes Well With: Water. I have used this product couple weeks and all cramps have gone. Also I sleep much better and at the morning I'm more energized. I recommend this to everyone who have a lot exercises. You are already signed up to our email! Added to your basket. Sorry, there seems to have been an error.

However, recent research suggests that the use of ZMA has no significant effects regarding serum testosterone levels and the metabolism of testosterone in subjects who consumed a zinc-sufficient diet.
Suggested intake: Zinc, magnesium and vitamin B6 are found naturally in many foods. Broschart names a few foods high in zinc: beef and other red meats, shellfish like oysters and shrimp , nuts and legumes. On the opposite side of the spectrum, the zinc in whole grain products and plant proteins has a lesser bioavailability due to their relatively high content of phytic acid, a compound that inhibits zinc absorption.
Broschart goes on to name foods high in magnesium bananas, nuts, shredded wheat, brown rice, milk, spinach and swiss chard and vitamin B6 fortified cereal, bananas, salmon, potatoes, chicken and turkey.
Most successful ZMA products have 11 mg of vitamin B6, mg of magnesium and 30 mg of zinc. Vitamin B6 toxicity, can cause neurological effects, but this only occurs when amounts exceed mg per day. Studies have found that zinc ingestion of about 60 mg per day through diet and supplementation can cause copper deficiency.
