Creatine is an amino acid located mostly in your muscles and brain. It supplies energy to your muscles, boosting power and performance, especially while you are exercising.†

Creatine helps boost exercise performance while training by providing increased strength and power. Athletes take creatine as a powerful tool to improve athletic and brain performance as well as reduce fatigue and tiredness.†

Micronized Creatine particles are 20 times smaller than creatine monohydrate. This makes it more easily absorbed and is considered to be more effective. In addition, micronized creatine does not tend to cause upset stomach.†

BCAAs, or Branched-Chain Amino Acids, are a group of three essential amino acids: leucine, isoleucine, and valine. These amino acids are called "essential" because your body can’t produce them on its own, so you need to get them from food or supplements. BCAAs play a huge role in muscle recovery and growth. Leucine is the powerhouse that kicks off protein synthesis, which is basically the process your muscles go through to repair and grow after a workout. Isoleucine helps with energy production during exercise and assists in muscle repair, while valine helps prevent muscle breakdown. Together, they help reduce muscle soreness, improve endurance, and support muscle recovery, especially after intense workouts.†
