What are the benefits of the LEVRONE GOLD MARYLAND MUSCLE MACHINE dietary supplement?

  • AAKG and citrulline malate are popular NO boosters, and their supplementation combined with diet and physical activity may prove valuable in increasing the flow of oxygen- and nutrient-rich blood to muscles, which may improve exercise capacity, body composition and trigger the ‘muscle pump’ effect[1-5]
  • Beta-alanine supplementation contributes to enhanced productivity and increased levels of carnosine in muscles (e.g. ensuring appropriate muscle pH value during physical activity), and may also affect training adaptation and some exercise capacity[6-10]
  • According to some studies, betaine supplementation may have a role in improving exercise performance[11-13]
  • Caffeine may prove to be a valuable component of athletic supplementation by affecting total energy levels, cognitive function, reaction time and some exercise capacity[6,14,15]
