I'm lactose intolerant. Can I use your protein powder? Click to expand

Yes! We tailor your personalized protein to your dietary restrictions.

One option we have is a pure whey protein isolate based blend. The whey isolate that we use in our blends is so finely filtered that it contains virtually no lactose. Unless you have a particularly acute case of lactose intolerance, you're unlikely to have any issues with this type of protein.

However, we also offer 100% plant-based blends that are not derived from milk and therefore contain no lactose whatsoever. Take the quiz and you will be given the option to choose your dietary restrictions.

If you have already taken the quiz, you can switch to a lactose-free blend by logging in and visiting the "My Info" tab. Edit your dietary restrictions and recalculate a new personalized blend.

Be sure to refresh your page after applying your changes in order to see your new blend. Your blend will only change if you have made meaningful edits to your quiz responses.

Thank you Gainful!

[…] I have hypoglycemia so finding a protein powder that didn’t have tons of sugar in it is a must. […] I’ve searched for months and months to find something that has this much protein, tastes good and doesn’t have sugar. So I gave it a shot and I’m not disappointed in the very least.

An all around great protein powder!

I love that they have vegetarian/vegan options and cater to your specific nutritional goals. A quick and easy process to order and it comes monthly with your chosen flavors.

Gainful cuts all of that guesswork out

I love that Gainful personalizes the powder to MY needs. It is so hard to find protein powder that works for what I want, but Gainful cuts all of that guesswork out. It’s also nice that you don’t have to commit to a flavor, you can just choose multiple!
