Deficiencies in Zinc and Magnesium are common in athletes. This results in
reduced testosterone levels, lack of performance, reduced recovery, cramps and
tiredness. ZMA can be used by all athletes wanting to
gain lean
muscle size and strength, including
bodybuilders, rugby players, sprinters and other strength athletes. ZMA is also
used widely by endurance athletes, such as runners, cyclists and triathletes, as
it helps to prevent the drop in testosterone levels linked with high volumes of
training.
ZMA
increases insulin-like growth factor-1 (IGF-1) which stimulates growth and
development of muscles by increasing the uptake of glucose and amino acids into
cells. Studies show that
ZMA increases muscle strength by around 11%,
resulting in
rapid gains in muscle size.
ZMA has also been to shown to improve sleep patterns when taken 30 minutes
before bed, resulting in increased muscle growth.
Many
studies show that most athletes are deficient in zinc, magnesium and vitamin B6.
A zinc deficiency results in decreased muscle endurance and lowered total work
capacity of muscles. Regular exercise results in
decreased zinc and magnesium levels, therefore requiring supplementation.
The
minerals zinc and magnesium have a number of important functions in the body.
Zinc has been strongly linked to the production of testosterone, a hormone that
plays a vital role in regulating muscle growth. In addition to its effect on
testosterone, zinc has also been shown to increase levels of growth hormone
and IGF-1. Both are essential for increasing muscle size.
Magnesium is also an essential mineral that is involved in more than 300
chemical reactions in the body including the oxidation or ‘burning' of fat.
Unfortunately, most people don't get enough of these minerals in their diets.
Clinical trials show that after just 14 days of supplementation, subjects showed
an impressive increase in muscular strength and endurance.
Even in men just moderately deficient in zinc, 30 milligrams daily was enough to
double testosterone levels in only six months.
Results
have been even more impressive when a zinc and magnesium combination has been
used. In one study, two groups of American Footballers took part in an 8-week
training program. One group was given ZMA, while the second group used a 'dummy
supplement. None of the footballers knew which was which. ZMA supplementation
led to a
33.5% increase in testosterone.
In contrast, testosterone levels actually dropped in the control group. IGF-1 (a
powerful hormone that plays a vital role in muscle growth) is normally lowered
in response to regular exercise. Yet, despite the intensive training program, ZMA users experienced a 3.6% increase in IGF-1 levels. In non-ZMA users, IGF-1
levels dropped by a 21.5%. These powerful effects on hormone levels also had an
impressive effect on muscle strength - ZMA users demonstrated
gains in strength that were 252% larger
than the control group.

Suggested
Use
As a dietary supplement take 3 capsules daily for men and 2 capsules daily for
women, preferably on an empty stomach, 30-60 minutes prior to bedtime. For best
results, avoid taking with foods or supplements containing calcium.
ZMA is reported to effectively enhance sleep
and is recommended to be taken 30-60 minutes before bedtime. Healing, anabolic
hormone production and muscle growth are maximized during sleep, so quality
sleep is extremely important to all of us.
Lorrie Brilla, PhD, a sports performance
researcher at Western Washington University, recently reported that ZMA
significantly increased free testosterone levels and muscle strength in NCAA
football players. These ZMA study results were presented by Dr. Brilla on June
2, 1999, at the 46th Annual Meeting of the American College of Sports Medicine
in Seattle, WA, and were published in the official ACSM journal, Medicine and
Science in Sports and Exercise, Vol. 31, No. 5, May 1999
Brilla reported that "a group of competitive NCAA
football players who took ZMA nightly during an eight-week spring training
program had 2.5 times greater muscle strength gains than a placebo group. (250%
better results!) Pre and post leg strength measurements were made using a Biodex
isokinetic dynamometer."
The strength of the ZMA group increased by 11.6%
compared to only a 4.6% increase in the placebo group.
Brilla further explained, "The muscle strength
increases may have been mediated by the anabolic hormone increases in the ZMA
group. The ZMA group had 30% increases in free and total testosterone levels
compared to 10 percent decreases in the placebo group... The ZMA group also
had a slight increase in insulin-like growth factor-1 (IGF-1) levels
compared to a 20 percent decrease in the placebo group. This study shows
that anabolic hormone and muscle strength increases can be induced in already
strength-trained athletes by using a novel zinc-magnesium preparation."
Another benefit is better sleep. ZMA should be
taken 30 - 60 minutes before bed. Most people notice they can fall asleep deeper
and then sleep more deeply. Don't be surprised if you start having very vivid
dreams while taking ZMA!
There has been a lot of research into the effectiveness
of ZMA Supplements.
ZMA has been used by dozens of world-class Olympic and professional athletes and
bodybuilders, including members of the Super Bowl Champion Denver Broncos and
Miami Dolphins football teams. It is also the only non-steroidal, all-natural
zinc and magnesium supplement clinically-proven to increase insulin-like growth
factor (IGF-1) and strength training in athletes. In a recent double-blind,
placebo-controlled study conducted with NCAA college football players,
researchers at Western Washington University found that eight weeks of nightly
supplementation with ZMA:
Increased plasma zinc
levels 29.1%, while placebo levels decreased 4.4%
Increased plasma magnesium levels 6.2%, while placebo levels decreased 9.2%
Increased total testosterone levels 32.4%, while placebo levels decreased 10.5%
Increased free testosterone levels 33.5%, while placebo levels decreased 10.2%
Increased IGF-1 levels 3.6%, while placebo levels decreased 21.5%
Increased muscle strength 11.6%, while placebo strength increased only 4.6%
In addition to the above more research which
demonstrates the positive effects of ZMA supplementation includes:
The effect of zinc depletion on muscle function
was tested in 8 male subjects. After receiving 12 mg Zn/day for 17 days, the
subjects received 0.3 mg Zn/day for either 33 or 41 days. The subjects were then
divided into two groups for zinc repletion. Group A subjects received overnight
infusion of 66 mg of Zn on Day 1 and 10 and then were fed 12 mg Zn/day for
another 16 days. Group B subjects were fed 12 mg Zn/day for 21 days. Peak force
and total work capacity of the knee and shoulder extensor and flexor muscle
groups were assessed using an isokinetic dynamometer at baseline, at two points
during depletion, and at repletion. Plasma zinc levels decreased by an average
of 67% during depletion and remained 9% below baseline after repletion. The peak
force of the muscle groups was not found to be significantly affected by acute
zinc depletion, however, shoulder peak force (strength) was found to be reduced
by 9.2% in the extensor muscles. Total work capacity (muscle endurance) for the
knee extensor muscles and shoulder extensor and flexor muscles declined
significantly by 28.1%, 24.1% and 26.4%, respectively. This study demonstrates
that muscle endurance, or total work capacity, declines rapidly with acute zinc
depletion and the degree of the decline was correlated with the reduction in
plasma zinc concentration.

A study was conducted to determine the effects of magnesium supplementation on
strength development during a double-blind, 7-week strength training program in
26 untrained subjects (14=placebo, 12= Mg), 18-30 years old. Pre and post peak
quadriceps torque (leg press) measurements were made using an isokinetic
dynamometer. The leg muscle strength of the magnesium supplemented group
significantly increased by 26%, compared to only 10% for the placebo group.

Serum zinc levels were determined in 160 training athletes (103 males and 57
females). In 23.3% of male and 43% of female athletes, serum zinc was
significantly below the "normal range".

Magnesium, zinc and copper status of 270 US Navy Sea, Air and Land (SEAL)
trainees was determined from dietary intakes and biochemical profiles. The
dietary intakes of 34% and 44% of the trainees were below the RDA for Mg and Zn,
respectively. The blood plasma concentrations of Mg and Zn were significantly
below the "normal range" for 23% and 24% of the trainees, respectively.

Serum zinc levels were measured in 20 adolescent gymnasts (9 boys, 11 girls, age
12-15). They had 26% lower serum zinc levels (0.599 +/- 0.026 mg/l) when
compared to 118 matched controls (0.810 +/- 0.014, p < 0.001). The gymnasts
serum zinc levels were positively correlated with adductor strength (r=0.468, p
< 0.05). The 11 of 20 gymnasts with serum zinc < 0.6 mg/L had lower insulin-like
growth factor binding protein 3 levels than the others (2.326 +/- 0.064 vs 2.699
+/- 0.12, p < 0.01). This protein is supposed to reflect growth hormone
activity. Thus, zinc is lowered in trained adolescent gymnasts and this
reduction could play a role in abnormalities of growth or muscular performance.

Res, 1995, Vol. 47, 273-278.
Twenty-one professional football (soccer) players underwent a maximal exercise
test on a cycloergometer, with progressively increasing workloads until VO2max.
On the whole these subjects had low serum zinc because nine (43%) of them had a
hypozincemia (0.54 +/- 0.01 mg/L) which suggested a zinc deficiency. The
subjects with low serum zinc had a 26% lower power output (123 +/- 8.71 vs.
166.27 +/- 14.84 watts, p = 0.029) and exhibited a 35% higher increase in blood
lactate (lactic acid) during exercise (7.51 +/- 0.81 vs. 5.57 +/- 0.33 mmol/L, p
<0.04) resulting in a 24% lower 2 mmol lactate threshold (44.7 +/- 3.9% vs. 58.9
+/- 4.8% of maximal power output p < 0.04). In conclusion, this study suggests
that zinc status may influence blood rheology (flow) during exercise by an
effect related to lactate accumulation.

Twelve professional volleyball players and 12 control subjects were studied to
determine the effects of daily physical training on serum, sweat and urine zinc
concentrations. The professional athletes trained every day in two sessions, one
in the morning (work in the gym for 2 hours) and another in the afternoon
(specific work on the sports field for 3 hours). Simultaneously, 12 male
volunteer university students, who were moderately trained, participated as the
control group. The study was conducted over a period of 10 weeks. Pre-post tests
were made using a progressive bicycle ergometer (increasing 30 W every 3 minutes
to reach a maximum tolerated power). Pre-post blood samples were obtained at
rest and immediately following exercise. After ten weeks of training, the
professional athletes showed a significant increase in 24 hour urinary zinc
excretion (22% greater losses), in contrast to a slight decrease (2% less) in
the controls. The athletes also showed a very significant increase in the zinc
loses in sweat compared to the controls. The athletes sweat zinc concentrations
increased by an astounding 300%, compared to only 30% increases in the control
group. The athletes serum zinc levels decreased by 4%, compared to a 2% decrease
in the control group. Finally, the post exercise cortisol levels of the athletes
significantly increased by 93%, compared to only an 18% increase in the
controls. The authors stated that the athletes "cortisol levels increased in
response to the exercise work load stress, and this behavior seems to be related
to muscular damage". The authors went on to say that "It seems that the changes
in zinc metabolism found in the study may be damage, increased protein turnover
and increased zinc excretion (via sweat and urine). Because strenuous exercise
during a period of competition can induce a "catabolic state" and has been shown
to increase skeletal muscle protein turnover, it is likely that urine zinc is
derived from muscle tissue". The authors concluded by saying that "Zinc
supplementation and/or stress control appear to be indicated in athletes. In our
practical opinion, we think that alterations in zinc metabolism with increases
in zinc excretion and stress levels lead to a situation of latent fatigue with a
decrease of endurance".

A percentage of testosterone is converted to dihydrotestosterone (DHT) by the
enzyme 5a-reductase. An invitro study was conducted to determine the inhibition
of 5a-reductase activity by zinc sulphate and azelaic acid. When added at
concentrations of 3 or 9 mmol/l, zinc was a potent inhibitor of 5a-reductase
activity. At a high concentration of 15 mmol/l, zinc completely inhibited
5a-reductase. The addition of vitamin B-6 potentiated the effect of zinc and
resulted in a two-fold increase in the inhibition of 5a-reductase. A moderate
concentration of 1.5 mmol/l of zinc in combination with 0.025% of vitamin B-6
inhibited the 5a-reductase activity by 90%. The zinc and vitamin B-6 combination
may be effective at limiting DHT production and could represent a potential
therapeutic agent in the treatment of androgen related pathology.

Androgen metabolism and aromatization, androgen and estrogen receptor binding
and circulating levels of reproductive hormones were studied in zinc deficient
rats. The zinc deficient group had significantly lower serum concentrations of
testosterone (2.8 +/- .07 nmol/L) compared to the controls (8.7 +/- .07 nmol/L).
This represents a remarkable 68% reduction in circulating testosterone levels.
Scatchard analysis of the receptor binding data showed a significantly higher
number of estrogen receptors in the zinc deficient group (36.6 +/- 3.4 fmol/mg
protein) than in controls (23.3 +/- 2.4 fmol/mg protein) and a significantly
lower number of androgen binding sites in rats fed the zinc deficient diet (6.7
+/- o.7 fmol/mg protein) than in controls (11.3 +/- 1.2 fmol/mg protein). To
summarize, zinc deficiency caused a 41% reduction in the number of androgen
binding sites and a 57% increase in the number of estrogen receptors. These
findings indicate that zinc deficiency significantly reduces circulating
testosterone concentrations and modifies sex hormone receptor levels.

Nine men participated in an 85 day zinc depletion/repletion study divided
into 3 metabolic periods: 18 day baseline, a 44 day depletion, and a 23 day
repletion. 12 mg of zinc per day was fed to the men during baseline and were
held constant after adjustments during the baseline period. Plasma zinc declined
from 77.1 +/- 0.03 mcg/dl at baseline to 28.1 +/- 0.07 mcg/dl at depletion;
concentrations returned to 77.9 +/- 0.03 mcg/dl at repletion. Total body weight,
fat, fat-free mass (FFM), and bone mineral did not change during depletion, but
total body water increased 5.3% +/- 1.9%, or about 2 kg or 4.4 lbs (P <0.05) by
the end of the depletion and returned to baseline values at the end of
repletion. The percent water in FFM increased from 71% +/- 1 to 75% +/- (P
<0.05) at the end of depletion and was associated with a small decrease in body
protein. The data suggest that zinc depletion impairs water balance.
