Best ZMA

ZMA — or zinc-magnesium aspartate — is a vitamin and mineral supplement containing a combination of the essential nutrients zinc, magnesium and vitamin B6 in an ideal ratio. (See Reference 1)

These nutrients are involved in a multitude of cellular reactions in the body and are needed for good health.

Health Benefits of ZMA

Athletic Performance and Muscle Growth

The research on ZMA is exciting when it comes to fitness and muscle building.

Getting more zinc, magnesium and B6 is important for people doing intense exercise. (See Reference 17) They’re often deficient in these nutrients as they are lost via sweat (See Reference 3) and rapidly used up during muscle synthesis and recovery.

Many studies have found that zinc and magnesium improve athletic performance, resulting in more strength, (See Reference 4) power and speed.

This is unsurprising considering zinc is involved in cell division and growth, (See Reference 5) thus encouraging muscle recovery and development. Magnesium and zinc are also necessary for the production of insulin-like (See Reference 6) growth factor (IGF-1) — important for cell growth.

Some of the other benefits of ZMA for physical performance may include:

  • Increasing energy by encouraging cellular ATP production (See Reference 10)
  • Removing lactic acid build up in the muscles
  • Enhancing muscle and nerve function
  • Improving the health of red blood cells and boosting oxygen levels in the body

Testosterone Levels

Both zinc and magnesium are necessary for healthy levels of the male sex hormone, testosterone (See Reference 8). They also prevent the drop in testosterone that occurs after exercise. (See Reference 9)

Interestingly, a laboratory study found zinc inhibited 5 alpha-reductase (See Reference 11) – an enzyme that breaks down testosterone. What’s more, this benefit was bolstered by the addition of vitamin B6. (See Reference 12)

This is great news for men as naturally higher testosterone levels improves libido, energy and muscle mass.

Thyroid Function and Metabolism

Zinc and magnesium found in ZMA may boost thyroid function and metabolism. (See Reference 13)

Interestingly, a laboratory study found zinc inhibited 5 alpha-reductase – an enzyme that breaks down testosterone. What’s more, this benefit was bolstered by the addition of vitamin B6.

A study on active and inactive men found that zinc supplementation increased thyroid hormone levels in both groups. Studies have also shown that zinc and magnesium prevent a decrease in thyroid hormones after exercise.

Restful Sleep

Both magnesium and zinc — in ZMA — have been shown to improve sleep quality. (See Reference 14) Magnesium, in particular, improves deep sleep. (See Reference 7)

This is promising because quality sleep boosts energy, (See Reference 15) encourages cellular repair, improves cognitive function, releases human growth hormone, reduces stress and lowers the risk of chronic health problems.

Immunity

Zinc, magnesium and vitamin B6 in ZMA are all necessary for fighting off infection and speeding up recovery. (See Reference 16) Vitamin B6 is needed for a healthy immune response and the production of infection-fighting white blood cells.

A 2004 review study found zinc exerts antiviral properties and significantly shortens the intensity and duration of a cold when taken within 24 hours of symptom onset. (See Reference 18)

Skin Health

ZMA may encourage glowing skin and speed up wound healing. Zinc works to reduce acne (See Reference 2) by decreasing oil production, providing antibacterial and anti-inflammatory properties and speeding up skin healing. (See Reference 22)

ADHD

Supplements containing magnesium, zinc and vitamin B6 — like ZMA — may positively influence the brain. (See Reference 20) Research has found these nutrients can reduce attention, behavioral and emotional problems in children with attention-deficit and hyperactivity disorder (ADHD). (See Reference 19)

Premenstrual Syndrome

ZMA may help women struggling with PMS and painful periods. (See Reference 21) This is thanks to magnesium and vitamin B6, which studies confirm reduce symptoms of PMS like breast tenderness, water retention, bloating and low mood. (See Reference 23)
