Whey concentrate retains more of the natural milk fats and flavor. At 80 g protein per 100 g, it costs less than isolate per gram of protein. A 9-week RCT (Fabre et al., Int J Sport Nutr Exerc Metab 2017) found no difference in lean mass or strength gains versus isolate.
How should I track Whey protein concentrate, unflavored?
Whey protein concentrate, unflavored is high in protein. Supplement tracking comes down to two things: measuring the supplement itself and logging everything around it. For powders like Whey protein concentrate, unflavored, a kitchen scale beats a scoop — scoops typically deliver 10–20% more than the stated serving (Almiron-Roig et al., Appetite 2013, found portion errors of 50–200% for dense foods). For capsules and tablets, count-based tracking is simpler but still matters at multiple daily doses. The real tracking trap is what you mix supplements with — milk, fruit, or nut butter can turn a 30-calorie serving into a 400-calorie shake. Log each ingredient separately for an accurate total.
