Understanding Protein Types
What’s the difference between whey isolate and concentrate?
Whey isolate is more processed, usually with higher protein content and less lactose. Whey concentrate is less processed, often with slightly more fats and carbs. Both are popular and widely used, and the right choice depends on your dietary preferences.
How do people typically use protein powder?
Many people include protein shakes as part of meals or after exercise. Others add protein powder into recipes like oats or smoothies. Usage varies depending on personal goals and diet. Always follow the instructions on the product label.
How should I store protein powder?
Keep protein powder in a cool, dry place with the lid tightly sealed to avoid moisture. Avoid storing it in warm or damp environments.
Choosing the Right Product
What should I look for in a protein supplement?
Key things to check include: protein content per serving, ingredient quality (minimal fillers and additives), certifications (such as Informed Sport), and whether it suits your dietary needs (vegan, lactose‑free, gluten‑free, etc.).
Are some protein powders marketed differently depending on goals?
Yes. Some products are positioned for higher calorie intake (often used for bulking), while others are marketed as lower‑calorie or leaner blends. At Protein Pitstop, we look at product information and overall value rather than marketing claims.
