Should you buy the Quest Nutrition Protein Powder (Vanilla Milkshake, 3 lb)?
Quest Nutrition Protein Powder is the 23g whey + micellar casein budget protein with only 1g sugar at $39 per 3lb tub. The 23g protein per scoop combines whey isolate (fast absorption) with micellar casein (slow release) for sustained amino acid delivery, the 1g sugar and 110 calories fit any macro target, the wide flavor range (Vanilla Milkshake tested) tastes closer to dessert than most protein powders, the gluten-free certified manufacturing supports celiac users, and the 3lb tub at $39 works out to $0.91 per 23g serving (better than premium picks). The trade is sucralose sweetening and a thicker mouthfeel from the casein blend that not everyone loves.
Frequently asked questions
Is Quest Protein Powder worth $38 in 2026?+
