I am amazed at how high this ranks! The chocolate flavor is completely flat, there is zero sweetness to this product I actually add honey to compensate for the lack of flavor. The only thing that brightened it up for me was some overripe pear chunks I had in the freezer. This powder would be best used in baked goods in my opinion. Overall the biggest problems I have with it is that it lacks flavor and also whips into this really airy consistency when you blend it, literally doubles in volume. It’s horrible. It really bloats me up and I have all these burps after drinking it.

Great product. For an unflavored product I expected it to taste like crap but it just had a mellow neutral flavor to it. It is over priced, i saw it in walmart for $34 CAD here it’s $45 CAD.

By far the tastiest naturally flavored/sweetened whey isolate on the market! Chocolate Peanut Butter tastes almost like a light coffee & Chocolate is a very nice hazelnut flavor, absolutely delicious! Just wish they ran some buy one get one free promos occasionally to make the price a bit more competitive w/other isolates. Highly recommended though!

All flavors of this are excellent for an all natural whey. Cleanest stuff out there and a good value for the money. The best if you're cutting naturally. Mixes really well. Banana was my favorite but they discontinued it.

while i loved the fact that IsoNatural contains no artificial colors, flavors or dyes there was just something about the taste that didnt sit quite right with me. the chocolate was very weak and had a weird aftertaste to me. perhaps i just got a bad sample because ive always been a fan of other Allmax flavorings.

Edit to my previous post. The new style container of Chocolate DOES contain Prebiotic's like the old style container. *Comparing the profiles of the old style container Vanilla vs the new style container Chocolate there is a difference as someone else posted and pointed out. The old style listed WAY more information including the Amino Profile where as the new style does not include that information, nor does it show the cholesterol.

I purchased this product multiple times in the past and I loved it !!But with the new changes I have to say I'll be looking elsewhere. It was ONCE cold processed which I'm a huge fan of . But Allmax decided to go for a higher protein content By filitering by Ion Exchange(2017 current) . It also no longer contains Probiotics and Amino profiling on the labeling and I'm sure there's more I haven't noticed yet . needs to update the product information because ALLMAX made some bad changes to this product and if the page was updated with correct information I would have looked for a different protein that meets my standards . Update the product information !!!!

I have tried a few different protein powders over the years and so far this one is my favourite. It mixes very well and taste amazing with plain old water or almond milk. Pros; - Taste Great - Low Calories - High Protein per scoop 27g protein for the one 30g scoop - All natural ingredients Cons; - Nothing so far

Got this as a sample from allmax. I had this post workout with 1% milk. I really like the idea behind the natural ingredients however there was something that was just a tad off on the flavor for me. Not sure if it was the natural sweetener but would be interested in trying another flavor.

Great flavoring for a natural protein, I never use natural protein powders because I've never had any issues with taking any whey powders but after taking and reading about Iso-Natural I would certainly use it again. If whey that has dye and flavoring gives you stomach issues or you just don't want to use it, Iso-Natural would be a great option for you!

This is an all natural option from Allmax for their protein powder, and has natural flavor and sweeteners with no artificial colors or dyes. It has comparable ingredient profiles to other protein powders, all while still being natural. The chocolate peanut butter flavor is great, especially for an all natural product. This is perfect for those looking for a healthy, natural option for protein powders!

This is currently my favorite, go-to protein powder! I bought the Vanilla flavored, which is not too sweet or overbearing when doing my shakes. It just gives the right amount of sweetness it needs! I also like the fact that it doesn't contain any sucralose, which is what I was looking for when researching and the powder quickly dissolves without leaving any clumps or powdery chunks. I have been using this for only two weeks and hopefully will see some gain thereafter but so far so good! I highly recommend this product for it's mainly naturally ingredients and great taste.

I had a few ALLMAX sample packs given to me at a supplement shop I visited a few months back. I really like how ALLMAX tests their protein for purity. I was told since the company is out of Canada, all the proteins are tested by law. I had the chocolate and the chocolate peanut butter flavors. Both had decent flavor and both mixed well with water and/or unsweetened almond milk. I would prefer the regular chocolate over the chocolate peanut butter if given the option. The peanut butter after taste was a bit off and chalky. Overall, I liked this product.
