Buying Guide
What to consider when choosing a low fat, low carb protein powder:
- Protein source and purity: whey isolate generally offers higher protein per serving and lower carbs. Isolate powders are often zero or low carb, while blends may include casein for slower absorption.
- Carb and sugar content: zero-carb formulas suit strict keto plans; otherwise, check net carbs per serving to fit daily targets.
- Flavor and texture: vanilla and chocolate are standard; consider unflavored options if you’re mixing into recipes or beverages.
- Dietary restrictions: gluten-free, soy-free, lactose tolerance, and vegan alternatives if needed.
- Ingredients clean-up: look for minimal additives and no artificial sweeteners if you prefer a simpler ingredient list.
