The AI answer we saw
Whey isolate contains 90%+ protein with minimal lactose and fat, while concentrate has 70-80% protein with more carbs and lactose. For muscle building, both are effective; isolate suits lactose-intolerant individuals and those tracking macros closely. Concentrate is more affordable. Choose based on digestive tolerance and budget. Protein content matters more than type for muscle gains.
