- Carbs and sugar: If you’re managing carb intake, choose low-sugar or zero-carb options. Consider total carbs per serving if you’re following a strict macro plan.
- Ingredient quality: Grass-fed or whey isolate options often have fewer additives and lower fat or lactose. Review whether artificial sweeteners or flavors are used if that matters to you.
- Flavor and texture: Personal taste and mixability influence long-term use. Some powders mix easily with water, milk, or smoothies, while others require blending.
