Which whey protein should I choose?

For most people, choose a whey isolate if you want high protein with less lactose and easier mixing; choose a whey concentrate if you want the best value and tolerate dairy well. If you’re unsure, start with an unflavored or lightly flavored whey isolate from a brand that provides third-party testing.

Quick decision guide:

• Best all-around: Whey isolate — higher protein per scoop, usually lower lactose, good post-workout or daily protein support.
• Best value: Whey concentrate — typically cheaper, still effective, but may have more lactose, carbs, and fat.
• Best for sensitive stomachs: Whey hydrolysate or isolate — often easier to digest, but hydrolysate can taste more bitter and cost more.
• Best for clean ingredient preference: Unflavored whey isolate — fewer sweeteners and additives.
• Avoid whey if you have a milk allergy; lactose intolerance may still be manageable with isolate, but allergy is different.

What to check before buying: protein per serving, total calories, sugar, ingredient list, whether it uses artificial sweeteners, third-party testing, and whether the serving size is realistic. A good target is roughly 20–30 g of protein per serving with ingredients you’re comfortable using regularly.
