It's Soya, it's not going to taste nice.
Seeing the reviews it's like a lot of people have never tried vegan protein before. This soya isolate is one of the better tasting vegan proteins. Being an isolate and so fine, it's texture is smoother than most. It's plant based protein, it doesn't taste nice and it's got a grainy texture. If you can't tolerate that then vegan protein powders may not be for you, unless you use it to bake with. I primarily use this as a cheaper way to bulk up my whey powder. 50/50 this and whey works well with some flavour drops. You can hardly taste the soya and the grainy texture is considerably more tolerable. It does need a damn good shake to mix fully, so I generally use a blender to speed it up.

Taste bad but great value
Tastes dreadful - very chalky texture. But good value for the macro content

Amazing stuff!
I was bored of milky shakes of whey. This is an excellent alternative and a lot more versatile as the flavour is near non existent. I can finally make savoury shakes with veggies and high protein content. I almost prefer this over whey and its cheaper!

Great choice
I’ve used different brands before, but this was my first time buying from Bulk and it’s been a great discovery. The consistency and flavour are really good compared to others I’ve tried. I use it in my overnight oats and it makes them much creamier and fluffier. I’ll definitely keep buying it.

It's the texture that's more of a problem for me than the taste.
I bought this so that I can have a dairy-free way of adding more protein to my diet. I am yet to mix this soy protein powder with water, but it doesn't blend smoothly in apple juice (a natural way of sweetening my porridges and smoothies). I use an electric, hand-held blender to mix my protein powder with my liquid of choice. PORRIDGE If you're using this protein powder in porridge, I'd advise you to blend the powder and your liquid of choice (mine is apple juice) first before pouring it in with your oats. If you try mixing this soy protein powder last thing, then the texture will be ghastly and it completely ruins the porridge's flavour. When done right, porridge with soya protein powder is fine. However, I do find that this soya protein powder weakens the apple juice's flavour. Nonetheless, I have found that adding a squeeze of lemon gives a bowl of soya protein porridge a nice zing. BAKING You can't really taste the soy protein powder once your batter/dough is baked off. Fortunately, it doesn't seem to affect the texture, either. Thus, this is a good protein powder to use in pancakes, brownies, doughnuts etc. SMOOTHIES I don't know how well this soy protein powder mixes with water yet, but, the only way for its grainy texture to be almost unnoticeable is if I blend my smoothie with two cups of frozen fruit straight out of the bag without defrosting it. That's one cup more than my usual. I'd rather have to use one cup, but the soy protein powder's grainy texture is disgusting. I don't know how much testing the company did before launching this product, but I think they ought to review how well this one mixes with a variety of different liquids (including juices) and ensure that it's smooth and not grainy. I can try blending with my electric blender for more than five minutes and it will still be grainy. Ugh! I have to say that I am a little disappointed in this powder because Bulk Powder's whey protein mixes fine with apple juice, but this one doesn't so much. However, on a more positive note, I like that I can overpower this soy protein powder's flavour with my usual fruits. Nonetheless, I will not be buying this again. I will finish this packet and then try out some high protein, dairy-free protein powders and see which ones mix well with apple juice and have very little impact on the overall taste.

Danger, tastes like Satan's butt crack
I've never left a review so soon after trying something before. But this, this unflavoured soy protein is so bad, so disgusting, it needed an immediate review. Others have to be warned! This protient powder will make you retch, you might actually throw up. It could be used for torture or acts or war. I tried mixing it with my favourite strawberry yogurt it still tasted like Satan's butt crack. I tried it with milk and chocolate sauce and still it made me gag like I had breathed in a demonic fart. I'm so sorry to Bulk for leaving a bad review because ordinarily they are my go to brand for protien shakes. But this is the first soy one I've bought and it was a total waste of money. It mixes terribly as well. Practically made a dough when I added in to yogurt and the other bulk protein powders have never done that. This soy protein powder is a weapon, a weapon to destroy your enemies with. It could bring any unsuspecting victim to their knees with just a sip. Use your new found power wisely. I'm going to offer the rest of my bag to someone I don't like.

Good quality and great value
Very happy with this product. It has more protein concentrate with less sugar. The consistency is good too..i compared with unsweetenedsoya milk, its much lower in sugar /carbs and fat than soya milk . i add a scope of this in cold water, mix well..then add to my hot coffee, put the combined to a microwave. Makes a delicious non sweet soy coffee. Very substantial and filling, like a breakfast...Without much sugar/carbs at all. I found the other good thing in this soy protein is that soy contains phyto estrogen. Mimic a female hormone which is largely decreased during menopause. This is a good thing for both protein and estrogen supplements for middle aged woman.

Cheap protein, good for lactose intolerant people
As someone who is lactose intolerant, I usually opt for whey isolate, but due to its high price, I decided to try unflavoured soy protein. While whey isolate tastes better, the soy protein isn't as "disgusting" as some claim—it's palatable, and I’ve had worse. The texture takes some getting used to, as it makes a thicker shake, but it's manageable. On the plus side, it's very easy on the stomach—possibly even better than whey isolate. Given the price difference, I’m happy with it, but if cost weren’t a factor, I’d stick with whey for the taste.

Today I got my delivery. It was so fast and great conditions . This is the first time I bought protein powder. Since I switched to vegetarianism, I needed a good product for my diet. I tried a cocktail with this product today, I really liked it. 🤌Good taste, good consistency, and most importantly, lots of protein. Recommend , and will be continue to buy

Esta marca tiene unos productos excelentes y a buen precio. La probé con recelo por el precio y ahora no la cambio. Compro la vegana y la animal. Limpia, sabor delicioso y se disuelve fácil si agitas. Recomiendo esta marca

Toujours le problème du goût pour les prot' abordables de toutes façons donc il faut trouver le mélange adéquate. 🤑 D'où probablement le bas prix étant donné que personne ne fait l'effort de faire sa propre mixture et en achète moins 🍒 15g dans l'overnight oats passe sans problème avec du Van Houten et des fruits rouges congelés. Et ça cale! ☕ Dans le shaker, avec du café en poudre, extrait de vanille, eau, lait de riz et beurre de cacahuètes qui lui, annule totalement le goût. Idem avec du Van Houten et fruits rouges 🍅 Et dans jus de tomates pour épaissir et faire un gaspacho maison et économique 🥞 Ça doit aussi parfaitement s'y prêter pour des pancakes protéinés donc à tester. Bref, suffit d'avoir des idées

Sehr guter Geschmack, neutral nicht aufdringlich und gut mit anderen Geschmäckern, Pulvern oder Obst usw. zu mischen. Das Pulver löst sich fein auf. Passt perfekt zB mit Blaubeeren und Wasser mit einem Schuss Hafermilch. Auch toll: Soja hat alle essentiellen Aminosäuren und ist daher bei Veganer Ernährung gut, um eine hohe Bioverfügbarkeit abzudecken. Wenn man es sonst noch mit weiteren Proteinquellen mischt kann man das dann sogar noch weiter steigern! Bin sehr zufrieden und werd ich wieder kaufen.

perfecto para mis necesidades, sin aromas, azucares etc. Lo añado a sopas y para hacer albondigas o salchichas veganas.
