Is it true that creatine just makes me gain water weight and look bloated?

No - it’s a myth stemming from one of the earliest studies, where participants took high doses of creatine and, after a week, their total body water was measured. It did increase over that week.

However, further research showed that creatine does not increase total body water in the long term. If water in the body does increase, it’s due to the gain in muscle mass that creatine supports, but the overall percentage of water in the body and in the cells remains the same. So you definitely won’t “puff up” after taking creatine, and any weight gain will be mainly muscle, not water.

Studies also show that creatine does not damage the kidneys, does not harm the liver, and does not cause hair loss.

Should I mix Whey Protein with water or milk?

That depends on you and your taste preferences - both options are fine.

Can people under 18 take creatine?

As this 2021 study shows, creatine supplementation in children and adolescents generally improves performance and is not associated with any adverse effects.

Therefore, based on the research, experts believe that consuming creatine poses no risk for people under 18.

Can I use Whey Protein even if I’m lactose intolerant?

Yes. Our protein contains no more than 1.2 g of lactose per serving, which is many times less than what a person with lactose intolerance can consume according to the latest scientific findings (approximately 12 grams).

What can I expect from taking creatine?

Whether you want to boost your performance in the gym, on the field, on the ice, or support recovery, performance, and brain health, Complex creatine is a supplement that absolutely shouldn’t be missing from your routine!
