FAQs
What’s the difference between whey isolate and concentrate?
Whey isolate is more processed to remove more carbohydrates and fats, while whey concentrate retains more of these nutrients. Choose based on your dietary preferences or tolerance.
Can I take whey every day?
Whey can be used daily if it fits your dietary needs. Always follow the serving instructions on the label and consider total protein intake from all sources.
Is whey good for weight loss?
Whey provides protein that can contribute to feeling fuller for longer when part of a balanced diet. For weight management, overall calorie intake matters more than any single ingredient.
How soon after a workout should I take it?
There’s no universal rule about exact timing. Many people consume protein around their workouts, but meeting your daily protein needs and following the product’s serving suggestions is most important.
