High protein plant milk alternatives you can buy (4 best I’ve tried)
If you're trying to get more protein into your diet, there is no denying that cow's milk is one of the best food products you can consume. It's a staple of most bodybuilder's diets, it won't break the bank, and it's very easy to consume too.
For those of you who can't drink cow's milk, such as vegans and people who simply have an intolerance/allergy to the product, it can sometimes feel a bit frustrating to not have access to a product that is as high in protein and as easy to consume as cow's milk. There are lots of tasty cow's milk alternatives out there, with more plant milks on supermarket shelves than ever, but the issue with most of these plant milks is that they don't contain anywhere near the amount of protein found in cow's milk.
Luckily, there are some plant milk alternatives that are pretty high in protein, and I thought it would be useful to round up the highest protein options that you can buy in the UK. What I found interesting is how widely the protein content of plant milk alternatives can vary from brand to brand. Let's take a look:
Alpro Plant Protein - 5g of protein per 100ml
With a name like 'Alpro Plant Protein', it probably comes as no surprise that this plant milk alternative is so high in protein. This product contains 5g of protein per 100ml, which is even more than you'll find in most cow's milk. The only downside of this product for me is that it's chocolate flavoured, so it's not as versatile as many of the other plant milk alternatives in this guide. But I thought this drink tasted really good and I'd happily use it for cereal too. Learn more and buy it here - sainsburys.co.uk
Bonsoy Soya Milk - 4.1g of protein per 100ml
Soya milk is the highest protein plant milk alternative that you can buy because soya beans are higher in protein than things like coconut, almonds, and oats, but the protein content of soya milk can vary quite a bit from brand to brand. I was impressed to see that this Bonsoy soya milk contains 4.1g of protein per 100g, which is almost 1g more than you'll find in the standard soya milk from Alpro, and almost 1.5g more protein than you'll find in the M&S Plant Kitchen Unsweetened Soya Drink. This soya milk from Bonsoy is apparently made from "a premium variety of whole soybeans", which is perhaps why it has a higher protein content than other soya drinks on the market.

Koko Unsweetened Coconut milk - 1.2g of protein per 100ml
I've always thought coconut milk tastes really nice, but I've also always been a bit frustrated at the low protein content of the coconut milk I've tried. For example, the Rude Health coconut milk drink contains less than 0.5g of protein per 100ml, and the same goes for the Plenish Coconut Milk. But for some reason, the Koko Unsweetened Coconut milk is much higher in protein, with 1.2g of protein per 100ml. So if you're a fan of coconut milk but you want one with more protein, consider switching to the Koko Unsweetened Coconut milk. Learn more and buy it here - tesco.com
Arla Jord Chilled Hemp & Oat Drink 1L - 0.9g of protein per 100ml
I'm a big fan of hemp protein powders and have tried loads of them. For those that don't know, hemp is a complete protein, meaning it has the same amino acid profile as protein from animal products. For this reason, I'm always surprised that I don't find more hemp milk on supermarket shelves. This hemp milk from Arla is made from a blend of hemp paste and oats, and I love the taste. It contains 0.9g of protein per 100ml, which might seem quite low but keep in mind that this is high quality protein with all essential amino acids, so it's a great option.

Hopefully, this guide proves that plant milk alternatives can still be high in protein. If you want to read something similar I published a guide about vegan protein powders.
