I love your products. The hydration singles are great for biking in the heat. Your pre workout mix gives me stamina

Hi Rafael, Thanks for sharing your experience! We're happy to hear our team was able to help out!
the product is amazing! I love how it's customized and made for me, that I have the ability to pick and choose between a variety of products and that I have the option to speak to a licensed nutritionist. The customer service has been great, and the orders arrive quickly and without any issues.

Hi Olivia, Thanks for sharing your experience!
This is the best protein powder I’ve ever purchased!!! It’s not just the products that are amazing, but the service and the education around the products are equally amazing! All the science behind the ingredient list is broken down so easily and all the products are personalized to my individual needs. The cherry on top is the fact that they provide you a personalized registered dietician and I’ve reached out and they got back to me with hours of sending a message with a fully detailed and easily explained response to my questions. Absolutely love gainful and would recommend it to anyone who’s a beginner to the workout supplement world or someone who has dietary restrictions and needs that personalized factor.

Absolutely love Gainful! Product is great, packaging is clean (love not having huge tubs of protein powder on my counter) and the service is outstanding!
