What are creatine and carnitine?

Creatine and carnitine are substances that play important roles in energy metabolism in the body:

Creatine

Creatine is involved in the rapid production of energy (ATP) in muscle and brain tissues. It is commonly used for improving exercise performance and increasing muscle mass. Creatine supplementation has also been studied for potential benefits in brain health and conditions such as depression. It operates by increasing the levels of the phosphocreatine system in the forebrain, which might improve neurological functions and mood regulation 1.

Carnitine

Carnitine, specifically acetyl-L-carnitine, plays a role in the metabolism of fatty acids, transporting them into mitochondria where they can be burned for energy. It has shown potential benefits in neurological disorders, such as reducing symptoms of ADHD in children via supplementation. Carnitine is also important for good mitochondrial function, which is crucial for overall energy levels and cellular health 2.

Both creatine and carnitine have unique roles, mainly revolving around energy production and modulation within cells, particularly in muscle and brain tissues.
