Many of you already know what creatine is. Many of you may also know how to take it, when to take it, and also what the best creatine supplement for you is. But do you know how it works? No worries, we’ve got you covered here.
But first, a quick little bit of background on Creatine. Creatine is an amino acid that helps to increase your body’s ability to produce energy, and helps you build more lean muscle mass. It’s mostly found in meats like beef, chicken and fish, and is also naturally produced in the body by the liver. As many of you know, amino acids are an important part of building, maintaining, and repairing muscles. Creatine in particular is very well suited for intense training that requires short bursts of energy, like sprinting or weightlifting.
Now that we know a little bit about creatine, let’s talk about how exactly it works. All of the energy used by your muscles during your workout comes from a molecule called Adenosine Triphosphate, or ATP for short. When you’re working out, the ATP breaks off one of its three phosphate molecules to create energy, becoming Adenosine Diphosphate in the process. Of course, once it’s broken off one of its phosphate molecules, the ATP molecule can’t produce any more energy for the body to use, leading to you becoming more tired as your body starts losing energy. That’s where creatine comes in. Once it’s entered your body, creatine will start giving its own phosphate molecules to the ADP molecules, turning them back into ATP and giving them more chances to produce energy for the muscles.
So now you know how creatine works on the molecular level, but how does this translate into what happens to your muscles? Don’t worry, we’re getting there. All of your muscle fibers are composed of many short little segments called sarcomeres. And each of those little sarcomeres contains contractile proteins called Actin and Myosin, responsible for muscle contractions, like the ones you experience while weightlifting. These contractions only occur when they receive a signal from the nervous system telling them to do so. And these contractions are all fuelled by the energy released by, you guessed it, ATP. And when you’ve got creatine in your body to support your ATP stores, you’ll have the energy to support more muscle contractions. It also helps that your muscle contraction strength is increased, which leads to increased workout intensity, which helps build more lean muscle mass.
So there you have it. Our comprehensive guide to how creatine works. Hopefully this will give you a better idea of how creatine works, and what benefits it has.
