Buying Guide
What to consider when choosing a protein powder for fitness

- Calorie and carb control: Choose options with low sugar and modest carbs if your goal is leanness or weight management.
- Taste and mixability: Flavor variety and how well the powder blends in water, milk, or beverages affect long-term adherence.
- Allergens and ingredients: Check for dairy, lactose, soy, or gluten if you have sensitivities or dietary restrictions.
- Intended use: Post-workout recovery, meal replacement, or convenient daily protein—different products fit different routines.
