Looking for an honest nu3 Vegan Protein review? This German-made, plant-based protein powder packs 21g of protein per scoop, a complete amino acid profile and, unusually for a vegan shake, a genuinely good taste. nu3 may not be a household name in the UK, but most of its range is available on Amazon and it has grown into one of the more popular plant-based protein brands here.
The big question is whether it actually delivers the nutrients you need to perform day to day, and whether it does so without costing far more than its competitors. Let's find out.
Vegan diets are becoming more popular, and that is good news. Plant-based diets have been associated with better health, lower stress, more energy, improved mood and greater concentration. That shift is driving demand for plant-based protein supplements like nu3 Vegan Protein, which regularly sells out across multiple stores. Unlike many of the upstarts of a decade ago, nu3 makes its own protein powders from plant proteins and now positions itself as a leading plant-based protein powder in the UK.
Vegan protein has long been a controversial subject in the health community, largely because plant proteins are often assumed to be less nutritious than animal-based sources. Some people even claim vegan proteins lack the nutrient ratios needed to support muscle growth and strength development.
Recently published medical studies, however, help dispel those myths [1] [2].
First, let's cover what we actually want from a good protein supplement and how nu3 measures up. Beyond the total protein per serving, two factors are often considered crucial to a supplement's effectiveness: its biological value and its amino acid profile.
Biological value is a measure of how well a protein is absorbed, commonly assessed through nitrogen balance. The science behind it is complicated and this is a big simplification, but the key idea is straightforward: the more of a protein your body can absorb, the more it can use to build its own proteins. nu3's blend is designed to be highly absorbable, helping you get the nutrients you need without feeling drained mid-workout.
The amino acid profile is more straightforward. It is simply a protein's composition of amino acids, the body's building blocks. Experts recommend prioritising the amino acids your body cannot make itself, known as essential amino acids, which are especially important for building muscle and healthy cells. A protein source that contains all of them is called a complete protein, and that is exactly what nu3's blend delivers.
For fitness goals, the essential amino acids that help build muscle (the branched-chain amino acids, or BCAAs) matter most. Leucine in particular plays a key role in muscle protein synthesis. With that in mind, what makes the best vegan protein supplement? In practice, the three most popular vegan sources (soy, pea and rice protein) can all be very effective.
Current scientific literature shows all three can increase markers of muscle growth, at times nearly as effectively as dairy whey, often considered the gold-standard protein supplement. What matters most is getting the right balance for your own body and nutritional needs. In my experience, nu3 vegan protein is a strong choice for increasing muscle mass and maintaining a healthy body weight.
nu3 Vegan Protein (available in four flavours) is one of the top plant-based protein shakes on the market. It's a delicious, nutrient-dense drink built around pea protein isolate and rice protein, and it mixes well with coconut milk, soy milk or fruit juice. Best of all, it comes in at a noticeably lower price than most other plant-based protein drinks.
Check price on AmazonIn recent years, animal-protein-free diets have become more appealing to health-conscious shoppers, not just committed vegans. nu3's plant-based blend is composed of ingredients including rice, cacao, lentils, hemp seeds, sea salt, carob germ protein powder and cashew. Although the ingredients are sourced from different continents, the product itself is made in Germany.
Compared with most other vegan products, the taste is closer to a dairy-style shake. It has only a slight creamy note and a smooth texture. It's available in four flavours (vanilla, chocolate, cookies & cream and strawberry) and comes in convenient 1kg and 2kg packages. For anyone who likes a more natural flavour or simply wants an affordable option, it's an easy recommendation.

Mixing tip
nu3 blends well with coconut milk, soy milk or fruit juice. Top it with coconut flakes for a richer shake, or stick to water if you want to keep the calories down.
With a 4-star rating based on over 2,150 customer reviews, it's fair to say nu3 is a quality, affordable plant-based protein powder for health- and fitness-conscious shoppers. The taste genuinely stands out among vegan options, the protein content is strong, and the price undercuts many rivals.
Each scoop delivers 21g of protein from a plant-based blend of rice and pea protein, with a complete amino acid profile and no animal ingredients, added sugar or artificial flavours.
It is available in four flavours: vanilla, chocolate, cookies & cream and strawberry. It also comes in convenient 1kg and 2kg packages.
Yes. It tends to come in at a lower price than many other plant-based protein shakes while still using high-quality ingredients, which is a big part of why it scores so well.
