• Differences between whey and isolate?

  • Sources:

    The main differences between whey protein and whey protein isolate revolve around their composition and processing:

    1. Lactose and Fat Content:

      • Whey protein isolate undergoes more processing to remove fats and lactose, resulting in a higher protein content and minimal lactose. This makes it better suited for those with lactose intolerance compared to whey protein concentrate, which retains more lactose and fat 1.
    2. Protein Concentration:

      • Whey protein isolate typically contains 90-95% protein, whereas whey protein concentrate contains about 70-85% protein.
    3. Bioactive Compounds:

      • Whey protein concentrate retains more bioactive compounds like alpha-lactalbumin and lactoferrin, which may offer additional health benefits 1.

    Both forms are effective for delivering essential amino acids crucial for muscle synthesis, but the choice may depend on dietary preferences regarding lactose content and protein purity 1.
