Quick take: iHerb makes it easy to browse supplements, protein, wellness products, and healthy pantry staples in one place. It’s a handy option for comparing ingredients, brands, and customer reviews before choosing what suits your goals.
The powder is so fine that its easily soluble. The flavour is not offensive at all for the unflavoured grass fed. I definitely recommend you to try it. Looking forward to buying more.

I always get unflavoured protein powder now because you can then add it to almost anything without getting a weird after taste.
This one, even being unflavoured, still tastes better than the usual.
It’s grass fed so a bit more expensive, don’t think you NEED to get this one over the other but i think grass fed is always better for the cows 🥹

Really happy this flavour is back in stock, and especially glad it’s back in tubs, I really didn’t like the sachets.
The vanilla honey flavour is banging. I mix 1 scoop with 200ml raw milk, add 1 tsp cocoa and a little maple, and it tastes like ice cream. Mixes well and is easy to drink.
Big plus for the ingredients simpler, cleaner as it should be, Sits well digestion wise too & no bloating.
Only downside is the delivery fee, which feels a bit high, but came next day like they said.
This is my go to protein powder, MP don’t discontinue it.

Other than in a protein shake this is no good, lumps up in overnight oats so end up with a mouth full of powder, emulsifies when mixed in the water or milk. The taste isn’t great but that is personal preference. I went for this because MP have discontinued the vanilla honeycomb which was my go to. Please bring in back.

This is the best price for 3rd party lab tested grass fed whey. It blends well, I accidentally bought the unflavoured but it’s actually fine just with milk and nice not having extra ingredients. I’m lactose intolerant and I have no issues with this at all.

MP, please do NOT discontinue this product! It’s so challenging to find a great tasting whey isolate WITHOUT acesulfame-K and sucralose.
The vanilla honey flavor is sweet, gentle, cozy, you can easily add it to greek yoghurt, or your preferred choice of milk. I use it with blend of 150 ml of caramel oat milk and 100 ml of water.
I would prefer if the product contain only stevia, I think adding the monk fruit is bit too much/sweet for my taste, but in general, among all of the other flavors and ingredients, this is my favorite.

I’m so glad I found this. I have tried both the chocolate and the vanilla with stevia. I can honestly say i have fallen in love with both of them.
I use the vanilla in baking and the chocolate one as a protein hot chocolate. It’s just so good! Please do not discontinue it or change the ingredients as you can see it’s very popular!
Also whey isolate is safe for lactose intolerance. I’ve had issues with whey in the past but this is perfectly fine.

I am glad they finally brought an organic and stevia sweetened protein powder, albeit the price isn’t the cheapest, I know I am getting the best for Keto, would prefer some more flavours but overall good as they used to do a keto version when they had silver packaging but glad this one is here.

Fab protein out there, NO additives, NO bad flavour, dissolves easily, i create my own natural flavours in Greek yoghurt with honey & berries & it is incredible. Please keep restocking unflavoured 😭😭😭🥹🥹🥹🥹
