If you’ve been looking into ways to get fit, build muscle, and stay in shape, then you may have heard of creatine supplements.

Creatine supplements are made from a natural compound that is known for muscle enhancement. These days, people have been using them to help with their athletic performance and work on getting stronger. You may notice that some people in your life who are really into strength training and working on their muscle mass at the gym take creatine to boost their performance naturally.

If you’re curious about the effects of creatine on the body, read more about what could happen if you take around 5mg of it for two weeks below.

You May Feel More Fullness In Your Muscles

There's a reason why muscle builders and those looking to bulk up enjoy taking creatine. When you consume 5mg of it consistently for two weeks, one of the first things you may notice a difference in is how "full" your muscles feel.

Jeremy Ethier, a content creator, fitness expert, and kinseologist, explains that "creatine pulls water into your muscles."

"You can also expect a 1 to 3-pound jump in your weight once this happens."

This tends to happen during the 'loading phase' of taking creatine, and while the swell and fullness of muscle may be temporary, it's a pretty interesting result.

You May Feel A Boost In Energy

Another reason why fitness enthusiasts enjoy taking creatine as part of their daily vitamin and supplement regimen is that they often feel a boost in energy once they take it. This extra bit of energy can help enhance exercise performance and allow for more effective and productive workouts, subsequently helping you build more muscle.

Angela S. Foster, a nutritionist and content creator, says consistently taking creatine can "support energy production" and even does more for your cognitive health than you realize.

"Creatine increases energy availability in your brain cells, supporting memory and focus precisely when hormonal fluctuations make you feel less sharp," she wrote under one of her Instagram posts.

Additionally, Ethier says that after taking creatine for two weeks, you can feel "enhanced exercise performance," and that you should pay attention to how you feel "after" your workouts, as it can also help with post-exercise recovery.

So, if you're a frequent exerciser or are looking for ways to up your strength-training game to focus more on building muscle, creatine may be an excellent supplement for you to start incorporating into your routine. It's highly researched and can help give your body an extra boost.
