The Active Ingredient Is: Creatine Monohydrate

Creatine monohydrate is a nitrogen-rich compound that helps to boost quick energy production in skeletal muscle during short bursts of high-intensity activity, which keeps you moving. This form is commonly used in sports nutrition as a supplement to aid muscle energy availability and support daily training goals, which many athletes relate to.

Creatine monohydrate is typically provided in powder form and is widely studied for its role in supporting athletic performance and muscle function when combined with resistance training, so it’s a familiar choice for many gym goers.

What Does Creatine Monohydrate Do?

Creatine monohydrate contributes to increased muscle mass and strength and supports high-intensity exercise performance when used with resistance training, which fits with guidance on energy metabolism and performance maintenance. In plain terms, it helps your muscles work harder, and that matters.

In the context of a calorie- and protein-dense formula, creatine helps support the energy needs of muscle work and recovery as part of a balanced sports nutrition approach, so it’s easy to see how it can fit into a busy training day.
