Cinar, V., et al. Effects of magnesium supplementation on blood parameters of athletes at rest and after exercise. Biol Trace Elem Res. 2007 Mar;115(3):205-12. Unlike a pre-workout supplement or even a caffeine pill , ZMA is not intended to improve your workout performance immediately. Instead, it is designed to enhance your recovery and boost your testosterone levels. If ZMA can bring about these effects, your workout quality and performance level will steadily improve over the long term. A: While zinc is not as well-studied of a sleep aid as melatonin or chamomile, there is some evidence linking zinc to better sleep. One study published in 2012 in the journal Biological Trace Element Research found that higher levels of zinc in hair samples (a proxy for dietary zinc intake over long periods of time) were associated with optimal sleep duration, compared to people who had lower levels of zinc ( 9 ). To raise your testosterone levels, opt for a ZMA supplement that’s got an adequate dose of both zinc and magnesium—two minerals with a proven connection to higher testosterone levels. MusclePharm Essentials Z-PM provides both in ample supply, plus includes the testosterone-elevating compounds copper and fenugreek extract. If you’re taking any medications or are pregnant or breastfeeding, speak with your healthcare provider before taking a ZMA supplement. Furthermore, avoid taking more ZMA than the recommended dose listed on the label. SummaryThis product has 422mg of magnesium (that’s 100 percent of your RDV) and 500mg of l-theanine, both of which help promote more restful sleep. Plus, you get 3mg of melatonin, which is a natural hormone that signals to your body that it’s time to go to sleep, according to the Mayo Clinic. And customers definitely feel the effects before they hit the hay. “Not only do I wake up feeling great, I was surprised at how much this mix puts me down to sleep,” one five-star review says. “I can’t keep my eyes open more than 15 minutes after taking.” Refined sugars, as well as white-flour products such as white bread, can lower blood levels of zinc and magnesium. Foods rich in calcium, such as dairy products, inhibit absorption of both zinc and magnesium by the small intestines. Copper, as well as foods rich in phytates (phosphorous compounds found in whole-grain breads, cereals, and legumes) also hinder the absorption of zinc by the small intestines. And alcohol decreases the absorption of zinc and magnesium, and increases their loss through urine.

Suggested Use

PhD Nutrition is about sports supplements that make a difference. Since launching in 2005, PhD have made some of my favourite supplements on the market. PhD know that high quality nutrition makes a difference and their supplements reflect that. A: Some people who use ZMA report that it gives them strong, vivid, or memorable dreams. The effects of any supplement on dreams is not a highly researched topic, but some circumstantial evidence does suggest a potential explanation for why ZMA might “enhance” your dreaming experience. For these reasons, it’s widely used by high-level athletes. If you want to boost your testosterone levels and increase your muscular strength or even improve your sleep, you could take advantage of these benefits too.

A: ZMA supplies your body with two important trace minerals and one key vitamin. The combination of zinc, magnesium, and vitamin B6 is thought to help your body boost levels of androgen steroids like testosterone and improve your recovery, particularly when you are asleep.

It’s worth noting that one of the authors of the study that found ZMA improved athletic performance has ownership in the company that produced the specific ZMA supplement. That same company also helped fund the study, so there may be a conflict of interest ( 11). Using careful statistical methods to control for possible confounding variables, the authors demonstrated that higher magnesium levels in the blood is linked to greater levels of testosterone, and greater levels of insulin-like growth factor 1 (IGF-1), another hormone strongly linked to strength, energy, and virility. Recommended Use: As a dietary supplement take 2-3 capsules daily preferably on an empty stomach. 30-60 minutes before bedtime, or use as directed by a physician or licensed nutritionist. For best results, men should use 3 capsules daily. The recommended dosage for women is 2 capsules per day. Avoid taking with dairy or other calcium containing foods or supplements.
