The scientifically proven ingredients have been strategically chosen for the impressive benefits that they provide. Vitamins C, B3, B6, and B12 work to support overall health, protect the body’s cells from free radical damage, improve energy levels, and boost brain function. While L-Citrulline works to improve physical and mental performance, and theobromine boosts the energizing effects of the formula.
The star of the show really though is N-Aceytl Cysteine (NAC) which increases glutathione, a super antioxidant and antitoxin. When you increase glutathione you give your immune system a real boost, improve your cellular function and even slow down the early signs of aging.
Simply mix a serving of the powder with 12-16oz of water and drink it up whenever you need to quickly boost your energy, focus, endurance, and immunity.
