Frequently Asked Questions

Is whey protein good for you?
Yes. Research consistently shows that whey protein supports muscle growth, aids weight management, and may improve heart health markers when consumed as part of a balanced diet. It is safe for healthy adults at recommended doses.
How much whey protein should I take per day?
Most research supports 20-40 grams per serving, one to two times daily. Your total protein needs depend on body weight and activity level, typically 1.2-2.2 grams per kilogram of body weight per day.
What is the difference between whey concentrate and isolate?
Whey concentrate contains 70-80% protein with some lactose and fat. Whey isolate is filtered to 90%+ protein with minimal lactose, making it better for lactose-sensitive individuals. Both deliver similar muscle-building benefits.
Can whey protein help with weight loss?
Yes. Whey protein increases satiety, preserves lean muscle during calorie restriction, and has a higher thermic effect than carbs or fat, meaning your body burns more energy digesting it.
