Reviews
Shockingly good
"I haven’t purchased from 1Up for years; I took some time off from fitness. I saw this flavor somewhere and was thrilled! I love cinnamon! I love coffee! Zero carbs, what!? No stomach upset. No bloating. This might be my perfect protein, guys. The coffee flavor is so good and it doesn’t have caffeine- I’m so thankful for that, don’t need extra caffeine!!!!"
Good option to mix with yogurt
"The flavor on this is pretty good, though I think not quite as tasty as the regular whey protein, and it's not quite as smooth/light as the clear protein isolate. But it does mix well with greek yogurt, so it's a great option if you're looking for that. I have only tried the Chocolate Peanut Butter Blast, so the other flavors might be a bit better. Overall I would say I like this one, but don't love it."
Best products
"I love my 1up products I got the clear protein and ISO protein AND creatine watermelon!"
Protein
"I love 1up products , the flavors are on point and does not disappoint. I have been using 1up since 2019 and I love their products very much. Some sour flavor are sour and some are not. The sweetness is subtler you cant taste the protein taste which I love. Clear protein is my favorite but I like to mixed it up."
This toffee flavor hits the
"This toffee flavor hits the spot with this protein! I wish there was actually slightly less caffeine in it because I already take pre-workout and so it is just a lot at once. I use this product not on the daily but when I need a bonus to my day or if I want to start my day off with a treat."
yummy!!!
"I was sooooo happy to find that 1up did an isolate version of this flavor. I love how wonderfully this protein powder mixes & tastes. It truly helps me stay on track and enjoy different ways of meeting my macros. highly recommend"
Pleased!
"I really like this brand! The protein drinks are smooth and tasty without being overly sweet. The greens and red are tasty as well and stacked with vitamins and nutrients that I'm positive I don't get with my one a day vitamin. Overall, I'm very satisfied with the quality and flavorings that I've gotten from 1up products."
Worth Every Scoop
"I've been really happy with 1UP ISO Protein. It mixes easily, tastes great, and has become part of my daily routine. High quality product, and I'll definitely be ordering it again!"
Too sweet
"I only bought this because the regular flavors have been out of stock for so long. I really wanted to like it, but unfortunately, the sweetness was too overpowering for me. Please bring back the regular flavors!"
