There are a lot of supplements out there that provide a mixture of multiple ingredients. Each ingredient and supplement has its reason and purpose.
BCAAs are an anabolic stimulus for the body. Twenty amino acids make up one complete protein. Eleven are nonessential, and nine are essential. The nonessential amino acids are naturally produced in the body. You can obtain the other nine amino acids through meats, such as chicken, steak, beef, fish, eggs, or supplements.
Some supplements have BCAAs, creatine, beta-alanine, or caffeine all in one. Be careful about which supplements you purchase. Always look at the ingredients before you buy any product.
Creatine monohydrate will help reproduce your ATP system during high-intensity exercise. This supplement is meant for activities that involve short-duration, maximum-effort exercises.
Creatine monohydrate would be beneficial for Olympic weightlifting, powerlifting, and short-duration power exercises. Creatine monohydrate will be helpful for anything fast and explosive.
Beta-Alanine is an excellent supplement to reduce "the burning feeling" that builds up in muscles during anaerobic or endurance training.
For example, if you participate in a boot camp, Crossfit class, or any other classes that combine multiple repetitions with a variety of different movements, beta-alanine will help reduce the burning sensation in your muscles. Depending on the dosage and fitness activities, beta-alanine will help improve your performance by delaying fatigue.
BCAAs are an anabolic stimulus, meaning that they stimulate muscle protein anabolism.
Since we are in a catabolic state during exercise, I do not recommend BCAAs during training. Overall, I do not recommend taking BCCAs with several other ingredients during your training.
