I hate protein powder but I love this stuff

The only protein powder I can have on a daily basis and does not give me the ick. I mix it with EVERYTHING!! The usual shake/smoothie/drink but oh so much more! Soup, cream cheese, humus (yes, I know). I can make any meal proteic without the gross artificial flavours and sweeteners. LOVE IT!

Allmax ISONATURALS has always been my favorite

This stuff has been around a long time, I think bought my first 5lbs almost twenty years ago. It mixes easily into cold liquids, and I always get the unflavored, cuz it is completely unnoticeable when mixed with any flavored drink. I prefer my own chocolate mix to the chocolate flavored isonaturals, and it can even be heated up for a cup of hot chocolate if you like. This is also the cheapest place to find this stuff that I can find..the same seems to apply to the other products I've purchased here.

Great protein powder.

Perfect with Coconut water

I like that it's completely unflavored with no unnecessary additives. If I want I can add coconut water, or milk and honey, agava syrup, etc.
And this is also a Canadian brand by the way

Best isolate you can buy

Unflavoured Allmax isonatural is by far the best whey isolate you can buy. All protein, no fillers that will mix into anything without any overpowering and unwanted flavour or textures.

Taste better than a tought

I wasn't expecting much from a clean ISO without Ace K or sucralose on the taste level but I was pleasantly surprised.

Pure with no sweeteners and no lactose after affects

Pure whey isolate and nothing else!!! When added to milk, it tastes like milk but with so much more protein!!! Great for fruit smoothies or almond milk protein shakes. I don’t get the crash/sugar spike like I do with whey concentrate. And there’s no artificial sweeteners after taste! You get so much more bang for your buck without the added crap!

Erica
Great product

I really like this stuff. It blends well and doesn't have much flavour or a weird texture so I can use it for sweet or savory dishes. I just had stomach surgery and have been mixing it in my blended soups. As long as I don't heat the soup too hot to the point where it coagulates, then it great!
I feel good using this and haven't had any stomach issues. I will definitely reorder when this tub is out.

Quality product

Excellent choice. Good enough price.
I am using it for many years.
There is some level of degradation in the ability to dissolve but that should not be a big issue if the taste is preserved.

Great unflavoured protein

Very happy with the unflavoured protein. Also very happy with price and speed of service. You’ve made a loyal customer.

Great in smoothies

Mixes well in my fruit smoothies. They're sweet enough as is so I don't need any additional flavoring and IsoNatural unflavored protein powder has been my go-to protein to put into them for years.

Allmax whey protein isolate

I've been using this product for over a year. It has a good milk chocolate flavour, not intense, dissolves very well even in milk and is not too sweet with stevia and no artificial sweeteners. Quality has been consistent.

Review of Allmax IsoNatural

I absolutely love this product and have been using it for 5 years now. It's very easy on the stomach and I think it tastes great for being unflavored. Go try it...Now! Just kidding but give it a go and you won't be disappointed.
