Loved by our Athletes

Iso-Smooth is hands-down my favorite protein on the market. The taste is unreal, and it’s one of the few that doesn’t leave me feeling bloated, gassy, or sluggish. With 30g of grass-fed whey and barely any sugar, it’s top shelf.

Steve Nesrallah

Iso-Smooth tastes so good it almost feels like I shouldn’t be allowed to have them while dieting. It mixes effortlessly with just water, and I also love adding it to my oats when I want something more filling. The texture stays smooth and the flavors are actually enjoyable, which makes it easy to stay consistent. The macros make it super easy to hit my protein goals.

Christina Hardway

I love incorporating Iso-Smooth in my daily stack. It’s a great way for me to get a quick 30g of protein when I’m on the go during busy days. All of the flavours taste great and mix well.

Maya Nowakowski

Iso-Smooth honestly makes hitting protein goals way easier. It tastes legit, actually craveable, and mixes clean. That’s huge when I’m on the go or in between clients.

Great Product

I have been a fan of this protein powder for quite some time now.
Being over 50 it's important to me to maintain muscle mass and good health so I've been investing in the great products here.
My most recent purchase, however, was a disappointment as this came in a BAG instead of the plastic container.
Not sure if they are trying to cut back on plastic but the twist-top canister was 100X better!
I tried using the bag earnestly but the closing zipper never really closed properly no matter how much I cleaned it - so I had to transfer it all to my Shake One canister and remove the label.
Otherwise, a great source of protein!

Protein Powder

My favourite protein powder which is usually sold out at my local supplier so I'm so happy I found it on line!! I have tried many over the years and this one is the best for me!!

Love the Tahitian vanilla. Mixes effortlessly and is my absolute go to when making ice cream with my ninja creamy!! I've used this to make egg white omelettes to bump up my protein and banana cookies etc and it's a hit every time!!

Fast delivery too and I'm loving the bag's versus the plastic tubs. Will be ordering here again!! Definitely 5 stars and I highly recommend!

Tastes great and mixes completely

First, the taste of triple chocolate and vanilla are superb. The creamsicle is also great, has a slight lemon flavour and i mix 1/2 and 1/2 with vanilla. I love that it completely dissolves in just water and zero chunky or gritty feel. Absolutely recommend.

My new favourite protein powder!!

ISO-smooth makes getting the quick protein in. It tastes so good and mixes well with milk/alternative and even just water. I look forward to having my protein shake everyday. Looking forward to trying other flavours.

Great product

Switched to ISO-Smooth chocolate peanut butter. The taste is great. It mixes well with water. Very smooth texture not chunky like my last protein. Should have switched this sooner.

The best in my humble opinion.

I have tried dozens of different protein supplements over the years and this is by far my favourite. The protein to calorie content is great (especially when you’re trying to cut down). It mixed perfectly in a shaker (no clumps and doesn’t stick to the sides). And the flavours are top notch ( Vanilla Bean and Chocolate are my faves). I’ll be a loyal customer for the foreseeable future.
