Your questions,
answered.

Is your protein 3rd party tested?
Yes - all of our products are manufactured in NSF certified cGMP facilities, the highest standard for supplement manufacturing. Each raw material is checked for safety and potency. Every Gainful product is third party tested for heavy metals and microbial contamination to ensure food safety and rotationally tested for adulterants and contaminants. Gainful products also undergo rigorous nutrient testing, to ensure potency and purity of ingredients, bringing you only high-quality products and peace of mind with every scoop.
How is Gainful protein different?
Our mission is to bring you premium, transparent, limited-ingredient protein. We use clean, effective ingredients in clinically-studied amounts, with nothing artificial, ever. Our products are 3rd-party tested for safety and efficacy. We know performance is personal, and that's why we offer a variety of products and customization that gets you what you need for your body and your goals. Plus - all Gainful proteins come unflavored, and we are the only brand with flavor packets that help you unlock a new protein flavor every day!
What time of day should I take protein?
What matters most is hitting your daily protein goals, not the exact timing. Spreading your intake across meals can help with fullness and muscle maintenance. If you're focused on building muscle or recovery, protein after a workout is ideal. Taking it before bed can also support overnight muscle repair. No matter when you take it, you'll get the benefits!
Is whey protein better than plant-based protein?
Whey protein is a great option if you tolerate dairy — it’s a complete protein with all 9 essential amino acids and is rich in micronutrients like calcium. For those who are lactose intolerant, Gainful offers virtually lactose-free whey options as well! Prefer plant-based? No problem. Our plant proteins combine organic pea and rice protein in a smooth, easily-digested blend to form a complete amino acid profile, so you’ll still get all the benefits of a high-quality protein blend!

How our flavor packets work

Step 1
Add 1 scoop of our unflavored protein to 8-12 oz of any ice cold milk or water

Step 2
Add 1 flavor packet to your shake

Step 3
Shake for 30 seconds and enjoy!
