Concentrate, isolate or hydrolysate?

Concentrate contains more lactose and fat than isolate. Hydrolysate contains proteins already broken into smaller pieces. The product’s own nutrition and ingredient lists matter more than the word “whey” alone. 1

What else is in the tub?

Whey products can include sweeteners, flavorings and other proteins. Verbraucherzentrale also highlights contamination risks in muscle-building products and points athletes toward the Kölner Liste as a screening resource. 1
