Product features ZMA - Anderson

ZMA - is a product based on zinc and magnesium, enriched with vitamin B6, designed to improve anabolic thrust by increasing the endogenous secretion of anabolic hormones. This supplement is characterized by a patented form, which covalently associates zinc / monomethionine with zinc / magnesium aspartate and vitamin B6. The above forms represent the formulations best absorbed by the human intestine.

Zinc: trace element present in nature prevalently in foods of animal origin and in some plants, where it is complexed to phytic acid. The most bioavailable form is obviously the one found in the animal kingdom, where zinc is associated with methionine, and for which enterocytic transport appears to be better. The daily requirement is set at 7 mg for women and 10 mg for men; it can therefore be achieved by simple feeding. Consequently, its deficiencies are present exclusively in some risk categories, generally accompanied by diseases of the gastrointestinal tract. The importance of zinc is due to its regulatory role, involved in intracellular singalling and hormonal secretion, to its structural role (part of the structure of transcription factors and membrane proteins), and its role as an enzymatic cofactor.

Several studies have shown how the need for zinc may increase following intense physical activity, and how its supplementation may be effective in modulating hormonal secretion during physical activity. The molecular mechanism by which zinc carries out its action remains to be investigated.

Magnesium: trace element introduced with the diet through whole grains, almonds and peanuts, fruits and vegetables, and foods of animal origin. In the human body, magnesium is found particularly concentrated in the bone and muscle, where it performs part of its biological functions. Fundamental in muscle contraction processes, in the structuring of bone tissue, it also actively participates in glucose metabolism, macromolecule synthesis and cellular activity regulation. Its daily requirement should be around 350 / 400mg, with increases due to intense physical activity for which a depletion of magnesium muscle levels has been demonstrated, with a consequent increase in renal elimination. Magnesium deficiencies inevitably affect the calcium metabolism, so much so that they are accompanied by hypocalcemia, bone rarefaction and widespread symptoms, characterized by asthenia, tremor, loss of appetite and gastrointestinal problems.

Supplementation in sports has shown a potential adjuvant role of anabolism, with reduction of the decrease in thyroid hormones and testosterone, increase in erythrocytes and hemoglobin, with consequent improvement in aerobic capacity, reduction in lactate production and better use of glucose muscle, including an increase in plasma free testosterone levels, documented in a recent study dated 03/30/2010.

Vitamin B6: present in this supplement in the form of pyridoxine, it is absorbed at fasting level after dependent ATP hydrolysis and transported to the liver bound to albumin. Here it is transformed into pyridosamine and then into pyridoxal and subsequently phosphorylated, with consequent activation and storage. From the liver it will reach various tissues, where it can perform its biological role, such as pyridoxal phosphate:

1. Increases blood glucose levels: it favors glycogenolysis and gluconeogenesis;
2. Promotes the synthesis of neurotransmitters such as serotonin, dopamine, norepinephrine and GABA.
3. Leads the synthesis of the EME group, necessary for hemoglobin to bind oxygen;
4. It allows the synthesis of Niacin, starting from tryptophan;
5. Modulates hormonal action;

Vitamin B6 is used in the treatment of numerous pathologies, with particular importance for those neurodegenerative, cardiovascular and in immune disorders.

Its daily requirement is around 1 / 1.5 mg, but even in this case the cases of deficiency are very rare.

Rationale for use - ZMA - Anderson

Although the literature shows various scientific evidences on the benefit of integration with trace elements in sports, the studies (a few) concerning the application of the ZMA seem rather disappointing. The only unpublished study, in which an increase in testosterone levels was obtained following ZMA administration, was subsequently denied by several independent studies, in which, unfortunately, the intake of this supplement was not has reported no benefit.

Although the integrator in question points to the more bioavailable form of the two trace elements, there is scientific evidence for which the intake of zinc could interfere with the absorption of magnesium, clearly unbalancing the balance between magnesium taken and magnesium eliminated in the urine .

Recommended use by the company - ZMA - Anderson

Swallow one serving (1 capsule) a day, 30-60 minutes before going to bed with water or other liquid of your choice on an empty stomach.

Use in sports - ZMA - Anderson

Given the failures of supplementation with this supplement in sports, there are no studies that define an optimal dosage, or at least to which we can realize benefits.

With regard to individual elements, however, it seems that in sports the most effective dosage is 10mg / kg / day for magnesium and 3mg / kg / day for zinc. At these doses, however, some side effects are documented, mainly concentrated at the gastro-intestinal level with diarrhea.

ZMA - Anderson side effects

Zinc: high amounts of zinc introduced are responsible for abdominal pain, diarrhea, nausea and vomiting. Chronic zinc administration (60 mg / day total) is associated with copper deficiency.

Magnesium: high amounts of magnesium are responsible for profuse diarrhea. The increase in serum magnesium levels is instead associated with hypotension, confusion, heart rhythm disorders, deterioration of renal function, fatigue, difficulty in breathing, and even cardiac arrest. The dose of safe supplementation appears to be 350 mg / day.

Vitamin B6: chronic administration can be responsible for damage to the nervous system and neuropathies of various levels already at doses higher than 200mg / day.

Interactions ZMA - Anderson

Zinc: in addition to interfering with other trace elements such as copper, it could reduce the absorption of some antibiotics such as tetracyclines, reducing their effectiveness.

Magnesium: may interfere with some antibiotics, tranquilizers and oral anticoagulants, reducing their effectiveness.

Precautions for use ZMA - Anderson

The product is contraindicated in cases of renal or hepatic disease, cardiovascular disease and / or hypertension, during pregnancy, during lactation and under 14 years.
