The only protein for people with IBS, lactose-intolerance, and issues with plant-based protein mixes
I've been trying all different brands of plant-based protein mixes for years due to lactose intolerance and IBS, and ALL of them cause gas, bloating and intestinal distress. I just recently realized that whey isolate was a more promising way to go, and came across Gainful's customized isolate. I'm amazed at the results—literally no intestinal distress, bloating, or gas. Flavors are what you'd typically expect and are above average. Would love it even more without the artificial sweetener.

Hi Mike! Thanks so much for leaving a review and we're so glad you're enjoying your blend! Our Flavor Boosts contain natural stevia extract and monkfruit extract. However, if you'd like to suggest other sweeteners shoot us an email at [email protected] and we'll make sure to forward the suggestion to our product team 😄

Pleasantly Pleased
I really like how few ingredients there are and how light and smooth it is - not chalky at all! I knocked off one star because it doesn't have much in the way of flavor, even when adding the flavor boosts. I also am not sure if an entire bag will get me through the month.
Response from GainfulSep 25, 2020
Hi Laura! So glad you're enjoying your blend! So sorry to hear that you're not enjoying the Flavor Boosts! Sometimes it takes a few tweaks to make your protein shakes taste better. Email our Customer Experience team at [email protected] and they'd love to help out with tips and solutions! Thanks so much for your review 😄

I was sent an extra order by mistake
I was sent an extra order by mistake. I was able to keep it free of charge despite me informing the support rep they could invoice me which was amazing! My issue was handled very quickly.

I love the product
I love the product. The protein powder has no aftertaste. I have used the personal nutritionist and found them to be very helpful.
