Good flavor mixes well

Review by Jack D on Sep 24, 2022
Switched from Whey to Plant protein recently due to lactose intolerance and there's been a lot less options. Came back to ole reliable at ON after shopping around a bit and very satisfied with it.

Delicious and satisfying

Review by Joe S. on Sep 24, 2022
Consistent results and taste. Not so easy to find in a plant protein. Kudos!

Buying again!

Review by Zach on Sep 15, 2022
Great protein that doesn't make me sick!

New formula is NOT IT

Review by Paige Mansfield on Aug 31, 2022
I’ve drank 4 scoops of the old formula a day, no problem. Now I’m trying this “new and improved” chocolate fudge flavor and it’s thicker, tastes so much worse and actually makes me sick. I’m constantly having stomach aches and I don’t look forward to my shakes throughout the day. Please bring the old flavor/formula back!!!

Perfect for Lactose-Free

Review by Dee on Aug 24, 2022
Amazing product. I recently started going back to the gym but haven't been eating enough to get where I want to be. In terms of maintaining/gaining body weight and getting to my goals as a person who can't have dairy, the taste, the consistency, and results are overall amazing so far.

I've tried them all!

Review by Steven E. Yates on May 28, 2022
I've been working out since 1984 and I've tried so many protein powders it's not even funny. When I switched to plant-based, there were fewer choices, but I have tried half a dozen (at least) of these and there is none tastier than ON Gold Standard 100% Plant-Based. The unflavored is great, the vanilla is fine, but I prefer the chocolate. I'm getting results using this product. What else is there?

Surprisingly delicious

Review by O. on May 23, 2022
Not too thick, mixes easily, good flavor, and no bad after taste. It's the hints of cinnamon that does it for me! Mildly obsessed.

Works for me as a plant based, gluten free protein powder – works well with fruit and vegetables in shakes.

Best plant protein powder

Review by Allan Gastwirth on Mar 11, 2022
Ben using this for years and it has great taste, good amount of protein content per scoop and for those needing a plant based protein, haven't found a better product
