8 Best Kefir Products | UK Nutritionist Reviewed

Biotiful Dairy is one of the UK's leading kefir brands, and there's a good reason why. Each bottle contains over 40 strains of bacteria (which is the highest on our list) and includes the tell-tale sign of quality kefir – billions of CFU's. As the name suggests, this particular product from Biotiful Dairy has an additional step in its brewing process: baking. 

By baking the milk before it begins fermentation, a sweeter, more mellow taste is produced rather than the typical sour tang of traditional kefir. That's why it's our top choice for complete kefir newbies! They also receive bonus points for not adding sugar.

Giants in the dairy space, Yeo Valley have been churning out delicious dairy goods for generations, producing a wide range of products from kinds of milk to ice creams. They've recently expanded the flavours of their kefir considerably, but sometimes you just can't beat the original.

It's the perfect base for breakfast, yoghurt pots, smoothies and drinks! With a relatively low sugar content, you can spoon away to your heart's content. It's creamy, smooth and has that delicious kefir taste along with the benefits of 14 live cultures. 

The Collective Dairy is big news in the world of kefir. They've begun branching into a variety of flavours in both drinks and yoghurts, but their Tumeric & Mango Cultured Milk Drink is one of their best. Containing 13 strains of live bacteria and billions of cultures, it's got the goods as well as the flavours. 

The key ingredient, turmeric, is hailed for its anti-inflammatory properties and the combination of mangoes is a match made in heaven. It's an excellent choice if you're still getting used to the taste of kefir. The sourness is minimal, and the smooth and creamy consistency makes it go down a treat!

This organic kefir milk from Arla is a favourite in the UK. These guys have been around for years, developing a countless number of much-loved dairy products like Skyr, and now they're branching out into kefir.

A litre bottle and a lighter texture makes for a perfect swap for your usual milk – pour it over cereal, pop it in your tea or drink it straight. It's not as creamy as the flavoured products, which makes it the best alternative to milk. The downside? Arla only mentions a couple of cultures on their product info, so it's hard to tell how effective the product might be.

The Collective's Coconut and Honey drink is flavoured with all-natural ingredients including honey blossom and apple and grape juice, making it taste like a creamy coconut milkshake but with the signature kefir twang.

However, just because it's made from coconut milk, don't be fooled into thinking it's vegan. Cows milk is mentioned as a key ingredient as it's used to ferment the kefir. With 6.7 grams of sugar per 100g, this isn't the healthiest option, but boy is it one of the tastiest! 

Who doesn't love vanilla? The Collective Dairy's yoghurt is as thick as Greek yoghurt but with the sweet taste of Madagascan vanilla and the signature light twang of kefir. This is an excellent pick if you're a newbie to the kefir game.

The product is excellent topped with muesli, fruit or enjoyed on its own, and has also been awarded the Great Taste 2019 award so you know it will be delicious. But that deliciousness does come at a price – its moderately high sugar count of 7.5 g.

With no added flavours, the original milk drink from Biotiful Dairy has that distinctive tangy kefir taste, but with its creaminess and light texture, it isn't overpowering at all. Packed with literally billions of cultures, this product contains over 40 different strains of kefir – which is a lot!

It's perfect for a healthy snack between meals or blended into a smoothie. Unfortunately, this bottle could end up being quite expensive, especially if you're pouring it over your cereal every day! But, it's an organic product which is high in protein and calcium, so you may be willing to forgive this. 

The first of Yeo Valley's products to make our cut is their delicious mango and passionfruit organic yoghurt. As well as being 100% organic, it uses natural flavourings such as mango puree, passionfruit and lemon juice. 

With raving reviews, this is one of the best-tasting kefir products on the market – but you pay for it with the sugar content. There's 9.7 g per 100 g, so, needless to say, it's not the best choice to be eating heaps of, but it is great dolloped on top of your morning muesli or on the side of a pudding!
