Should I mix Whey Protein with water or milk?

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

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).

Can I overdose on protein?

No.

The only risk with excessive protein intake is digestive issues, such as bloating. That’s why we recommend not exceeding a daily dose of 2 to 3 scoops.

Does protein damage the liver and kidneys?

No.

Based on the latest studies, neither protein nor a high protein intake (at least 2.8 grams per kilogram of body weight per day) damages the kidneys or the liver, this is a myth.

Is Whey Protein suitable for children as well?

Yes.

If they are not getting enough protein (1.6 to 2 grams of protein per kilogram of body weight) from their diet.

Studies show that protein supplementation can effectively support children’s growth, health, and immunity when given in an appropriate amount.
