Gainful earns positive reviews as a customizable protein and hydration brand that tastes good, mixes cleanly, and offers vegan options with clever flavor boosts, yet its personalization feels generic to some and several users report chalky texture or underwhelming results. Reviews also flag inconveniences with separate flavor packets and occasional subscription frustrations, while strengths include gentle-on-stomach blends, clean ingredients, and enjoyable flavors like Cookies & Cream, Chocolate Peanut Butter, Berry, and Tropical Mango.
