| Protein per serving: | 21g, 23g, 25g |
- Customer review: "I am very impressed with the USN plant-based protein, especially considering the relatively low price compared with other vegan proteins. I have tried dozens of them, including some more expensive brands like Form and Awesome. To be honest, I can't stomach protein shakes at the best of times and most of them go straight in the bin, so anything which is remotely drinkable is a keeper. But this is more than just drinkable and is definitely the best I have tried so far! Both vanilla and strawberry actually taste quite nice! I use a blender to mix this with half water and half soya milk, but it actually tastes ok with just water. This is not sickly sweet like other brands and doesn't have any of that earthy mud like taste you usually get with vegan proteins! I will definitely continue to order this."

It's not grainy when you put it in your post-workout shake and it flavours my porridge really well if I'm looking to add extra protein to my daily intake. A scoop is enough and tastes ok with water, but I prefer to add mine to oat milk for a more milkshake taste.

I add it to my porridge, smoothies and stews. I tried the pea protein before but I prefer the soya one. It also has more protein content than the other one. No GMO so it is a winner. It wasn't my first purchase and it is definitely not the last one! Quick delivery as well and no problems with the seller.

Protein powders are a staple for me as well as pre-workout and BCAAs to help with recovery. SMART PROTEIN's chocolate protein powder tastes very chocolatey, which is ideal for a chocolate fiend like me that needs a fix. The strawberries and cream flavour however, was on the wrong side of the real deal for me as personally, it tasted too artificial."
FAQs
What are protein powders?
As we learned in biology lessons, protein is a macronutrient which the body uses to fuel and repair itself. Protein is found in animal products like meat, fish, eggs and cheese, as well as nuts and legumes.
Protein powder is exactly what it says on the tin - concentrated powdered sources of protein. It can be mixed with water or milk to make a shake and can also be used in pancakes, cookies, porridge and more.
Generally used by people who lead an active life, it can be useful for increasing your daily protein intake to aid things like muscle gain, weight loss and overall performance.
What types of protein are there?
Whey protein
Easily the most popular protein type available and the one you've most likely heard of, whey protein is made from a by-product of cheese or milk production. It's what the industry calls a complete protein, meaning it has all nine essential amino acids the body needs.
One of the things that throws people off about whey protein is the various forms it comes in; concentrates, isolates and hydrolysates.
Whey protein concentrate is typically made up of mostly protein (60-80%), with the rest being fat and carbs. It's the most popular option for beginners as it's budget-friendly, absorbed fairly quickly and retains most of the beneficial nutrients of protein.
Whey protein isolate goes through an additional filtering process which removes more fat and carbs, making the protein more concentrated. It contains around 90–95% protein. If you're counting macros or are on a high protein/low fat/low carb diet, this might be better suited to you.
Whey protein hydrolysate is the final form of whey protein, created by heating the product further to break down the bonds between amino acids. It's generally the most expensive option but is quickly absorbed into the body and contains the most amount of protein per serving.

Casein protein
Whey is one of the types of protein found in cow's milk, the other is casein. Casein is a slow-digesting, complete protein which can make you feel fuller for longer. Many people use it as an overnight repair, taken just before bedtime. It's also useful for cooking as it's a thicker consistency.
Casein also comes in a couple of forms; micellar casein, which is digested slowly, and casein hydrolysate, which is quickly absorbed. It's generally thought of as a good protein for weight loss.
Soy protein
Made from soybean, this complete protein contains all nine essential amino acids. It's a good option for vegetarians and vegans. Soy is rich in nutrients and some research suggests that it's as effective as some animal sources of protein.
Hemp protein
Another plant-based complete protein, hemp protein, is derived from ground hemp seeds. It's easily digestible, high in fibre and rich in minerals and antioxidants, but it does have an earthy taste which can take some getting used to.
Rice protein
As rice protein is naturally dairy-free and gluten-free, it's great for those with dietary restrictions. Usually made from sprouted brown rice, it's a good source of B vitamins and fibre and is packed with antioxidants.
Brown Rice Protein contains all of the essential amino acids, and despite being seen as inferior to whey, it actually has the closest amino acid profile to mother’s milk out of all known protein sources, according to research. Unlike some dairy proteins, rice protein is less likely to make you feel bloated, but it is digested more slowly.
Pea protein
If you have allergies to soy or whey, pea protein is a good all-rounder. Formed from yellow split peas, which are high in protein, this option is also high in fibre and iron, plus it's easy to digest. It's a complete protein and is absorbed at a medium-fast rate.
Some people like to incorporate a couple of protein powder sources into their routine, so may use peas along with whey or soy to ensure they cover all the bases.
Egg protein
When many of us think of protein, eggs always come to mind. Derived from dehydrated egg whites, egg protein powder is a complete protein which can be a good option for those with sensitivities or an intolerance to milk products. It's digested more slowly than whey but more quickly than casein.
Bone broth protein
Bone broth protein is, you guessed it, made from cooking bones, ligaments and tendons (usually chicken or beef) in water. It's full of nutrients which are said to boost your immune system, improve skin, digestion and joint health. Bone broth protein is dairy-free, soy-free, gluten-free and paleo-friendly, so it would suit a range of people. It doesn't contain all the essential amino acids, but it does have a rich amino acid profile.
How does protein powder work?
Protein powder is a dietary supplement that provides a concentrated source of protein from various sources, such as whey, soy, peas or other plant-based sources. In short, it works by supplying your body with a digestible source of protein that can be used to support a variety of physiological processes.
One of the primary functions of protein is to help with the growth and repair of muscle tissues. Taking part in activities like resistance training will require your body to repair and rebuild muscle fibres, especially if they have been damaged during a workout. So, the addition of protein powder into your diet will help provide the necessary amino acids, which are often referred to as the 'building blocks' of muscle.
Another function is post-workout recovery. Protein powder is often consumed after a workout to kickstart the muscle recovery process. The quick absorption of protein helps replenish those amino acids we keep talking about and repair any muscle injuries which may have occurred during exercise.
One further role of protein is to use it for dietary supplementation. For people with specific dietary preferences or allergies, like vegetarians and vegans, protein powders are a great way to obtain more protein into their diets as they may not get enough from just a plant-based diet alone.
Do I need protein powder in my diet?
It's key to acknowledge that protein powder is a supplement and not a substitute for whole foods or meals. Protein powder is not a supplement for the essential nutrients food contains, like vitamins, minerals, fibre and antioxidants. So, in short, nobody has to incorporate protein powder into their diet. Saying that there are some things you should consider if you think that protein powder is necessary in your diet, like whether you're a vegetarian or vegan, or a professional athlete, or if you require it for convenience.
