All good from a protein point if view. Gets abit thick in some instances. Usually roll a scoop of protein with natural yogurt but gets too thick which turns it It into a paste.On a side note.....do we have an eta for a cooked breakfast in a dehydrated meal??literally the last piece if the puzzle. 🤘🏽👌🏽

I have been using Radix Whey Protein for a while now and it’s by far the best whey protein I have tried. The taste is delicious and the quality of ingredients used made me have no doubts about choosing it. I have bought some bags of the whey protein to take with me when traveling overseas as the price and quality are excellent and I was afraid of not finding such a good product in Brazil. I also needed some assistance with one of the parcels that were sent to my address and the customer service was outstanding sorting out the problem straight away. I am very pleased that I can find a great product made in NZ. Definitely my only whey protein source from now on.

Probably one of the best protein powders out there in my opinion. Mixes well with water(gets very frothy)/milk/yoghurt. Not grainy whatsoever, very smooth consistency. Will be purchasing again when I run out which will be very soon at this rate!
Best whey protein product I've come across!The flavour is perfect, not too sickly or sweet. Tastes great either with either water, or milk for an even creamier consistency. Mixes quickly and perfectly- no gross lumps or clumps.
This is by far the best protein I have ever had. I’ve been using Radix Protein for over three years now and I will not use anything else. It tastes fantastic and is super easy to use. It’s great on its own or mixed in with berry smoothies or yoghurt. I love all the flavours but my favourite is the strawberry.
Delicious, filing, easily blends, smooth. Perfect protein powder! I love this mixed with Greek yoghurt and berries. My husband takes it when travelling for a smoothie to avoid eating rubbish for breakfast/lunch. It will definitely be a staple in our house.Highly recommend x
I brought the single serve to test if this was going to live up to the hype. I have never come across a strawberry protein that I actually like … it either doesn’t taste like strawberry or the mix is terrible. I wasn’t disappointed. This tastes FANTASTIC and when mixed has no clumps. Loved it … so I brought the big bag (along with the chocolate and vanilla) now looking forward to seeing the physical results.
I’ve used this protein powder in smoothies and find it blends to a creamy consistency. I don’t love the monk fruit sweetener, I find it’s too sweet so I wouldn’t purchase this again. That being said, I will certainly purchase the unflavoured protein powder when it comes back in stock.
I’ve been really enjoying using this powder. It mixes so easily in to my morning porridge. I have tried coconut and vanilla, preferring the vanilla as the coconut a wee bit overpowering. The only gripe is I use far too much with that big scoop and I can’t be faffed weighing it out all the time, small world problem. I will however alternate between this and the Clean Nutrition as I enjoy both.
