Reviews

Best protein!!

"My absolute favorite protein. Have tried many different brands and always come back to 1UP because it’s not grainy, texture is smooth and has a delicious flavor to it. My favorite is the salted caramel. Goes perfect with my cup of black tea. I use a frother to mix it with well with oatmilk then add to my tea. My morning sweet treat."

Maricela F. (5/5)

I Love 1Up Nutrition Salted Caramel Protein

"I absolutely love 1Up Nutrition ISO Protein in the Sydney Adams salted caramel flavor. It is the best tasting protein out there. Clean ingredients for 110 calories and 25 grams of protein. You cannot beat this. I always have to order double because I go through it so quickly."

Sharon J. (5/5)

Obsessed

"Amazing flavor! This combined with the choc coconut collagen is a GAME CHANGER im obsessed!! Thank you for offering quality products that’s actually work and taste absolutely amazing !! 10/10"

Keleigh L. (5/5)

I really like 1 Up

"I really like 1 Up ISO protein. I was actually surprised the day I used 2 scoops with 16oz of skim milk and I was amazed at how long it kept my hunger away. I was satiated for several hours. The Caramel Macchiato gives me the flavor of coffee without me running to waste calories and money at the local coffee shops."

Tawana G. (5/5)

Yum

"This is delicious. I use it to bake with, and it adds such a sweet desserty flavor while helping me meet my protein goals! I love how rich of a flavor it has. In smoothies and shakes, it isn’t super grainy like other protein powders I’ve had. I love it"

Margaret C. (4/5)

Very sweet but great protein!

"I do really love the product and the flavor. However, it is extremely sweet so I need to use half the serving, which means I don’t get as much protein. That said, I do like it and I use it in my coffee and overnight oats, it’s good for sweetening them and adding a bit of protein."

Anna L. (4/5)

Easy to Drink, Easy to Stick With

"I’ve tried a lot of protein powders, and the salted caramel from 1UP ISO Protein is easily one of the best tasting. It’s smooth, lightly sweet, with just the right touch of salt and no artificial aftertaste. It mixes really well too, no clumps or chalky texture, just a clean, creamy shake. Overall, it’s a great option if you want something that tastes good and makes it easy to stay consistent."

Ben F. (5/5)

Protein Breakfast Shake

"I really love making Cinnamon Toast Crunch X Salted Caramel or Trix X Chocolate Milkshake protein shakes for breakfast. It’s a great way for me to make my protein goal for the day and supplement my breakfast in the morning!! Highly recommend the iso whey protein flavors as they’re easy on the stomach to digest. I’ve used a few other protein brands and this by far is the tastiest."

Katherine R. (5/5)

Mixes completely, no lumps no

"Mixes completely, no lumps no clumps. No bitter aftertaste goes down smooth and it taste great."

Cheryl W. (5/5)

Delicious is an understatement

"Delicious! Healthy substitute for my dessert cravings. Almost tastes similar to back in the day when Alani Nu first launched her munchiez flavored protein and it was my favorite. So I am extremely happy with this flavor, it’s nostalgic and delicious"

Sara C. (5/5)

Q&A

I am wondering if either the whey or ISO whey protein powder are soy free. I know they say there could be cross contamination due to production facility but I cannot find on the label if there os soy product in the actual protein.
Hello Sierra. Yes, the Whey Protein and ISO Whey don't contain soy ingredients. Kind Regards
Can this be taken while pregnant or trying to get pregnant?
Hello Vanessa. It's best to consult with your doctor on the safety of consuming the ISO Whey or any other supplement products while pregnant or trying to get pregnant. All ingredients in the product are fully listed on the product page under description. Kind Regards
If I buy a flavor and end up not liking the flavor, do you guys return our money or send a replacement flavor? How does that work?
Hello Yajaira. Yes, we have a company 30 day returns policy. Please see the full company returns policy by visiting the 1UP website then scroll to the bottom of page under help click returns. To complete a return please email customerservice@1upnutrition.com Kind Regards.
Hello! Are all the Whey & Iso protein powders gluten free? I have multiple and I don’t see A GF mentioning on it and need to know. If there are certain flavors that are GF or are not. Can you please list them for me :)
Hello Hoda. Most flavors will be Gluten Free for the Whey Protein except for flavors that contain gluten containing ingredients such as the flavors Mint Cookies & Creme and Cookies & Creme which have wheat flour a gluten containing ingredient. Kind Regards.
If I order the strawberry milkshake flavor and mix with my vegan red and green pineapple that I already had, will they taste weird?
Hello Vy. There is only one way to find out if it will taste weird or good. We have not tried mixing those two products together to see what it would taste like. You can certainly try it out if you'd like. Kind Regards.
