JYM Supplement Science ZMA is a dietary supplement that is a combination of zinc, magnesium, and vitamin B6. It is marketed as a testosterone-booster and has been used by athletes and bodybuilders for muscle growth and strength improvement. The zinc and magnesium in ZMA have been found to have an effect on testosterone levels, but more research is needed to confirm the effectiveness of the supplement. Additionally, vitamin B6 is important for overall health, specifically it helps the body to convert food into energy and also helps to form red blood cells. 

Each dose of ZMA JYM delivers the perfect form and dose of zinc (30 mg), magnesium (450 mg), and vitamin B6 (10.5 mg), as well as an effective/the recommended dose of Bioperine (5 mg), which has been shown to enhance the uptake of zinc, magnesium and B vitamins. 

Some potential benefits of ZMA include:     

• Increased muscle strength and endurance: ZMA contains zinc, magnesium and vitamin B6 which are important for muscle function and recovery.     
• Improved athletic performance: ZMA may help increase testosterone levels, which can help improve athletic performance and muscle growth.      
• Better sleep quality: Magnesium in ZMA can help to relax the muscles, which can promote better sleep.     
• Improved immune function: Zinc is important for a healthy immune system, and ZMA may help to boost the immune system.      
• Reduced stress levels: Magnesium can help reduce stress levels and promote a sense of calm.      
• Improved cardiovascular health: Vitamin B6 is important for cardiovascular health, and ZMA may help to support the cardiovascular system.

The cost of ZMA supplements can vary depending on the brand and the size of the package. Some brands offer 30-day supplies for around $20, while others offer 90-day supplies for around $50. Some brands may be more expensive than others.  In general, ZMA is considered to be an affordable supplement option compared to some other dietary supplements. The cost may vary by location as well, and prices can also vary between online and brick-and-mortar retailers. I have found the best deal on JYM ZMA directly through Amazon and buying it here.
