Obsessed with their hydration product I ordered the lemon lime hydration product and it's my new favorite way to hydrate. I wasn't drinking enough water throughout my day, because frankly, I think water alone is boring. The lemon line flavoring was super good and I've probably doubled my daily water intake since purchasing from Gainful. Highly recommend!

Sham Decent tasting, fine product. Absolutely not actually personalized. The "quiz" gathers extremely base information about you and your diet, along with a couple questions about your goals. But in the end, you get one of just a few pre-made blends of supplements. There's no semblance of biometric personalization or any other science to it. It really is "what protein can you ingest? Plant or animal?" Honestly, if you already know the answer to this, you don't need this service in the least. Zero percent worth the cost. Save yourself time and money and just go buy protein mix from your local grocery store.

Great stuff! Love that there is a Registered Dietician you can easily reach out to with any questions. The personalized protein is fantastic, and I enjoy being able to swap between flavors. I also don't have to worry about having a huge tub I have to go through before trying a new flavor, and I can opt to skip a month if I haven't been as diligent in my workouts for a while.

Not your AVERAGE protein powder I haven’t even RECIEVED my protein powder yet but I’m throughly impressed by the attention given to their customers. It’s a whole different experience than just buying any brand protein powder GAINFUL reached out to me to let me know they have dietician’s to assist me with questions over diet or exercise going forward this is on top of custom preparing your own protein powder. I really can’t wait to get my protein. Thank you again Gainful

This change made it a struggle to meet my strength goals AND have the mental energy to stay focused all day, UNTIL I started using this brand. My energy levels and recovery are the best they've ever been!"
