What's in ISO Whey Zero

Essential amino acids

Histidine, Lysine, Methionine, Phenylalanine, Threonine, and Tryptophan


Valine, Isoleucine, Leucine

These are amino acids that cannot be made by the body and are therefore required to be taken in by supplements like this. This supplement also includes high levels of the three key BCAAs. Each 25 g serving of Whey ISO Zero contains 10.4 g of EAAs and 4.5 g of BCAAs.

Whey ISO Zero also includes a range of non-essential and conditionally essential amino acids under its protein content, each 25 g serving contains 4.6 g of NAAs and 6.4 of CAAs. A 25-gram supplement serving contains 21 g of protein content, with only 1.7 g of the serving being made up of carbohydrates and fats.

Our Verdict

A strong range of amino acids: EAAs, NAAs and CAAs which build up the protein content in this supplement. The Vanilla flavour contains the highest protein content at 97% which is why it has been included in this review. The extremely low carbohydrate and fat content already make this an appealing product. In addition, Whey Zero being a lactose-free supplement makes this ideal for lactose intolerant users who may have struggled to receive a high protein content.

Whey Isolate is always a handy supplement for receiving more pure protein without the downside of unwanted high carbs and fats. As a result, we have been quite a fan of this supplement, especially with the vanilla flavour that contains the highest amount of protein. Additionally, vanilla is a flavour you can rarely go wrong with and it certainly makes it easier not to get bored of the flavour if you choose the larger bottle.
