Product Summary

Gainful protein powder is an all-natural, high-quality protein personalized to fit your needs, goals, and lifestyle. You first complete a quiz on the Gainful website which asks about your diet, body composition, and lifestyle. Based on these results, a registered dietician creates a protein blend to best meet your profile. They provide a complete breakdown of the nutrition in the specific formula created for you. All of Gainful’s protein blends come unflavored with the option of adding seven single-serving flavor boosts free of charge.

The flavor-pack options include a variety pack, sea salt caramel, cinnamon toast, Madagascar vanilla, rich cocoa, chocolate peanut butter, strawberry cream, cafe mocha, and cookies & cream. Every blend includes all nine essential amino acids and a protein count that ranges anywhere from 19 grams to 27 grams per serving.

Gainful is a subscription-based program which automatically renews each month, so it’s not an ideal choice for everyone. But with your subscription you receive unlimited access to registered dietitians via email, chat, or text. Because of this, Gainful is pricier than many other protein powder supplements.
