What is Kefir?
Firstly, what is kefir? Made by fermenting milk with grains of bacteria and yeast, it can be dairy or non-dairy.
Kefir is a powerful probiotic food packed with over 30 strains of beneficial bacteria and yeast (Science Direct, 2025). This makes it more diverse than regular yogurt, which typically contains only a few strains.
What’s more, kefir will literally make your gut bugs do the happy dance! Which is why it’s one of my favourite foodie healthy hacks!
What Are the Specific Probiotics in Kefir That Benefit the Gut Microbiome?
The wide range of probiotics in kefir supports digestion, gut balance, and immune health.
Key Probiotic Strains in Kefir
- Lactobacillus kefiranofaciens – Strengthens the gut lining and may reduce inflammation.
- Lactobacillus acidophilus – Supports digestion, nutrient absorption, and immune defense.
- Bifidobacterium species – Helps balance gut flora and ease bloating or IBS symptoms.
- Lactobacillus casei – Encourages regular bowel movements and may relieve constipation.
- Saccharomyces kefir (yeast) – Fights harmful bacteria and candida overgrowth in the gut.
- Leuconostoc species – Produces short-chain fatty acids that support gut cell health.
- Lactococcus lactis – Reduces inflammation and improves lactose digestion.
Added Probiotic Boost with Gut Healthy Supplements
When I want to give my skin and gut health an extra boost, I add a quality probiotic supplement to my daily kefir routine. One of my go-to probiotics, YourBiology Gut+ contains a powerful mix of 20 Billion CFU probiotics and 10 different strains. Furthermore, it contains 2 prebiotics to help feed all the good bacteria!
I particularly like the addition of digestive enzymes, which helps me with bloating, and so it also features in our best probiotics for women review.
How These Probiotics Benefit the Gut Microbiome
- Restore balance – The mix of probiotic strains in kefir helps repopulate the gut with good bacteria.
- Support digestion – Kefir contains natural enzymes, such as lactase, that help break down dairy sugars.
- Lower inflammation – Many strains in kefir have anti-inflammatory effects that support gut healing.
- Boost immunity – As a probiotic food, kefir strengthens gut-based immune responses.
To gain the full benefit kefir can offer, drinking one cup of plain, unsweetened kefir daily is recommended. It’s an easy way to support your gut microbiome, improve digestion, and enhance overall health.
💡Bonus insight: Early studies suggest kefir may also support brain health in conditions like Alzheimer’s, but more research is ongoing (Tanure YCB et al, 2025).
So, why should I drink kefir?
9 Milk Kefir Benefits

1. A probiotic boost
Many (including myself) drink kefir for gut health because it’s a rich source of probiotics. Probiotics are beneficial microorganisms that can support a healthy balance of gut bacteria.
What’s more, it’s a relatively cheap and tasty way to boost gut health. Above all, I love kefir in smoothies, on granola, over, e.g., blueberries, or just as a plain drink on its own.
In fact, kefir smoothie recipes is one of our favourite ‘gut healthy suplpements’ when life gets busy.
For example, this Blueberry Kefir Smoothie is a super simple and gut healthy snack!
2. Supports digestion
Kefir can help with digestive issues, because the probiotics in kefir can help break down lactose. In essence, this can make it easier to digest if you’re lactose-intolerant.
3. It’s nutritent dense
Some kefir milks are a good source of several essential nutrients, including calcium, protein, and B vitamins. These nutrients affect overall health and when coupled with your favourite fruits, can be a fantastic start to your day.
For example, try one of our most delicious mango smoothie recipes with probiotic kefir for a gut healthy start to your day!

4. May boost immunity
The probiotics in kefir may influence the immune system. This link between probiotics and immunity can help you fight off harmful bugs. Perhaps a glass a day could keep the doctor away?!
5. Reduce inflammation
The probiotics and active compounds in kefir may be anti-inflammatory. As a result, kefir may benefit those with inflammatory conditions.
6. Support bone health
Kefir is a good source of calcium and vitamin K2. These nutrients are essential for maintaining strong and healthy bones. Being 50+ myself, I’m conscious of choosing foods and fuel that offer health benefits, as well as yummy taste!
7. Nourish skin from within
I love a quality kefir for healthy skin as well as improved digestion. Packed with essential vitamins, minerals, and beneficial bacteria, kefir milk works wonders to nourish and rejuvenate the skin from within. As a medical microbiologist with a passion for skincare and wellbeing, I love the beauty benefit kefir offiers, also because I feel my skin needs less products to look and feel its best!
Specifically, the probiotics and nutrients in kefir may contribute to healthier skin by promoting a balanced microbiome.

What’s more, I love a kefir face mask because its natural probiotics help soothe my sensitive skin. A kefir face mask nourishes the skin, enhances hydration, reduces inflammation, promotes a healthy glow, and supports a balanced skin microbiome. Simply apply a thin layer to the face and let it sink in!
From personal experience, drinking kefir regularly as well as using it as a face mask has calmed my skin no end!
Probotic Supplements for a Skin-Gut Health Boost
When I want to give my skin and gut health an extra boost, I add a quality probiotic supplement, with multiple strains, to my daily routine.
One of my go-to probiotics, YourBiology Gut+ contains a powerful mix of 20 Billion CFU and 10 different strains. Furthermore, it contains 2 prebiotics to help feed all the good bacteria!
I particularly like the addition of digestive enzymes, which helps me with bloating, and so it also features in our best probiotics for women review.
8. May influence mood
Science shows that probiotics like those found in kefir may affect mood and mental well-being. Surprisingly, some probiotics influence communication between your gut and your brain. As a result, what you eat can directly affect how you feel!
One of my favourite probiotics for mood is L reuteri – aka The Love Bug – which may help against stress AND skin problems!
9. Support sleep
While kefir is renowned for its digestive health benefits, emerging research and anecdotal evidence points to the probiotic benefits of the kefir and sleep connection. We explore that in more detail below.

What Are The Different Types of Kefir?
Primarily, what differentiates different types of kefir is the liquid used in the fermentation process.
Additionally, variations may arise based on regional traditions, production methods, and the specific strains of bacteria and yeast present.
Here are some common types of kefir milk:
Cow’s milk kefir is the most common type, made by fermenting cow’s milk with grains for kefir. This produces a creamy, tangy beverage with a consistency similar to yogurt.
Goat’s milk kefir: similar to traditional milk kefir but made using goat’s milk. Goat’s milk kefir may have a slightly different flavor and composition compared to kefir made with cow’s milk.
Coconut milk kefir is a dairy-free option made by fermenting coconut milk with grains for kefir. It offers a tropical flavor and is a popular choice for those seeking plant-based alternatives.
Other types of kefir include sheep’s milk kefir, water kefir, and lactose-free kefir.
I’m Lactose Intolerant, Can I Enjoy Kefir?
Many wonder whether it’s possible to experience the benefit kefir offers, if you’re lactose-intolerant.
Kefir may suit you if you’re lactose-intolerant, because fermentation reduces the lactose content in the milk. The live bacteria and yeast in kefir grains break down lactose into simpler sugars, such as glucose and galactose. As a result, the lactose content of kefir is significantly lower compared to regular milk.
However, many still find that they still react to traditional kefir. Luckily, many other options are available these days.
Alternatives To Dairy Based Kefir
There are several non-dairy kefirs if you are lactose-intolerant or follow a plant-based diet.
Some common alternatives to dairy-based kefir are:
Water kefir, coconout kefir, goat’s milk kefir, nut milk kefir, oat milk kefir, and hemp milk kefir.
If you prefer non-dairy kefir milk, then try to choose unsweetened and unflavored varieties to maintain the health benefit of kefir milk while avoiding added sugars.

Homemade versions of non-dairy kefir can be made with the same fermentation process as traditional kefir. Substitute dairy milk with the desired non-dairy option and ideally use grains for kefir suited to your milk of choice.
Are There Any Side Effects to Drinking Kefir?
While enjoying the natural probiotic in kefir is generally considered safe for most people when consumed in moderation, some individuals may experience side effects or adverse reactions.
Below are a few potential side effects of drinking kefir.
Photo by Anshu A on Unsplash
- Digestive discomfort: Some people may experience temporary digestive issues such as bloating, gas, or diarrhea when first introducing kefir into their diet. This is typically due to the probiotics and active cultures in kefir, which can temporarily disrupt the balance of gut bacteria until the body adjusts. Start with small amounts and build up the amount of kefir you drink, but don’t overconsume. Listen to your body!
- Lactose intolerance: Kefir is a fermented food that still contains some lactose, the natural sugar found in milk. While the fermentation process reduces the lactose content, people with lactose intolerance may still experience discomfort or digestive symptoms after consuming kefir. In such cases, opting for lactose-free or non-dairy alternatives to kefir may be a better option.
- Allergic reactions: Individuals with dairy allergies or sensitivities may experience allergic reactions after consuming fermented foods such as kefir. Symptoms may include hives, itching, swelling, or difficulty breathing. If you have a known allergy to dairy products, it’s best to avoid kefir or choose non-dairy alternatives.
- Histamine intolerance: Fermented milk kefir contains histamine, a compound involved in allergic reactions. Some people may be sensitive to histamine and experience symptoms such as headaches, flushing, or nasal congestion after consuming kefir or other histamine-rich foods. If you have histamine intolerance, you may need to limit your intake of kefir or choose low-histamine varieties.
- Drug interactions: There is limited research on potential drug interactions with fermented foods such as kefir, but some studies suggest that probiotics in fermented foods like kefir may interact with certain medications or affect their absorption. If you’re taking medications, especially antibiotics or immunosuppressants, it’s advisable to consult with a healthcare professional before adding kefir to your diet.
Overall, while the benefit kefir milk (and kefir yogurt!) offers are pretty clear, it’s essential to listen to your body and monitor how it reacts to this fermented beverage. If you’re concerned about dangers of kefir or you experience any adverse reactions or discomfort after consuming kefir, it’s best to discontinue use!
Consult with a healthcare professional, if in doubt, and if you have underlying health conditions or concerns.

How to Choose the Best Kefir Brands For Digestive Health
If you’re wondering how to choose the healthiest kefir, among the myriad brands popping up, make a mental note of these 5 general tips for choosing the best kefir:
1) Look for “live and active cultures” to ensure probiotic benefits
2) Choose unsweetened varieties to avoid excess sugar that can harm gut health (I look for around 5 g/100 ml, as recommended by nutritionists)
3) Consider dairy-free options like coconut or almond milk kefir if lactose intolerant
4) Check for fortifications in vitamin D and calcium to support bone health
5) Go for organic brands to minimize additives and artificial ingredients
Here’s a list of the top kefir brands that are non-dairy and low-sugar (0–2 g/100 ml), plus where to find them!
Kefir vs Yogurt: Which Is Better For Gut Health?
If you’re wondering which is better for gut health, kefir yogurt or kefir milk, the benefit kefir milk offers is a slightly higher probiotic content.
Kefir vs yogurt: which is better for gut health?

Kefir milk typically contains a broader range of probiotic strains because the fermentation process occurs directly in the milk. The kefir grains ferment the lactose in the milk, producing a variety of beneficial bacteria and yeasts. Some of the commonly found probiotic strains in kefir milk include Lactobacillus acidophilus, Lactobacillus kefiranofaciens, Lactobacillus kefir, Lactobacillus fermentum, and Bifidobacterium species, among others.
On the other hand, kefir yogurt is made by straining kefir milk to achieve a thicker consistency similar to traditional yogurt. During this straining process, some of the probiotics may be removed along with the whey, resulting in potentially lower probiotic counts compared to kefir milk.
However, kefir yogurt still retains a good amount of beneficial bacteria and yeasts, so you can definitely enjoy the same probiotic benefit of kefir milk!
In any case, I always check the product label or even inquire with the manufacturer to determine the probiotic content of a particular kefir product.
A word about flavoured kefir drinks
If you’re keen on the benefit kefir milk offers, but don’t like the sour taste, then a flavoured kefir might be for you! Personally, I like the tangy taste of natural kefir but totally get that it’s not for everyone. And the main thing is to get to enjoy the benefit of kefir milk and its probiotic bacteria!
Just recently I was enjoying a delicious honey flavoured kefir yogurt. However, with the relatively high sugar content (11g/100ml), next time I will be adding local honey to natural kefir, to get the double immunity boost.
Some good brands with low sugar (~5%) include delicious vanilla tastes, which are great for gut healthy smoothies:
Kefir Vanilla – Biotiful Gut Health
In addition, adding natural flavour to kefir with fruits, berries and honey are a great way to combine prebiotic and probiotic benefits. For more prebiotic and high fiber food inspo, check out this article with lots of super tips to feed your gut microbiome with prebiotic fiber!
If you’re after more of a treat, then the YAAR Bars are a delicious alternative to afternoon sweet treats!
Want to Make Your Own Kefir?
Making kefir at home, using grains for kefir, offers several health benefits due to their rich probiotic content.
What’s more, with a decent milk kefir recipe, you’ll benefit from cheaper, customized kefir free from additives.
However, what I’ve discovered, in my experience it’s not always as easy as simply adding kefir grains to milk, and leaving this mix to ferment (as some kefir recipes state). In fact, many kefir making experts help the fermentation process along with a ‘fermentation booster’ such as inulin, or other prebiotics (e.g. honey). I’ll be exploring that in more detail and report back as I discover the ultimate recipe for home made kefir, with the broadest range of probiotics possible.
Meanwhile, you can also get kefir grains at good-quality health stores and some high-end food stores also sell grains for kefir. Even Amazon is in on the trend and have started to sell grains for kefir!
The Kefir Sleep Connection: A Natural Sleep Aid
In today’s fast-paced world, quality sleep has become a coveted commodity. Many of us struggle with sleep, insomnia, or general restlessness, and seek various natural remedies for better sleep quality. Amidst the myriad of solutions for better sleep, one natural sleep remedy and increasingly popular option is kefir—a fermented dairy product rich in probiotics.
While kefir is renowned for its digestive health benefits, emerging research and anecdotal evidence points to the probiotic benefits of the kefir sleep connection. So, why could kefir help you sleep?
The connection between gut health and sleep
The link between gut health and sleep quality is well documented. The gut microbiome, a complex community of microorganisms living in our intestines, has a profound impact on various aspects of our health, including our sleep patterns. An imbalance in the gut microbiome can lead to inflammation, which has been associated with sleep disturbances and disorders. Kefir, being a potent source of probiotics, helps in balancing the gut microbiota, thereby potentially enhancing sleep quality.
Probiotics in kefir such as Lactobacillus and Bifidobacterium strains contribute to a healthy gut environment. These beneficial bacteria assist in the production of neurotransmitters like serotonin, which is a precursor to melatonin, the hormone responsible for regulating sleep-wake cycles. By promoting a healthy gut, kefir indirectly supports the body’s natural ability to manage sleep.
Better Sleep And Less Stress
Stress and anxiety are common culprits of poor sleep. The probiotics in kefir not only support gut health but also have a positive impact on mental well-being. Studies have shown that the gut-brain axis – the bidirectional communication between the gut and the brain – plays a crucial role in managing stress and anxiety levels. By improving gut health, kefir may contribute to reducing stress, thereby creating a more conducive environment for sleep.
Furthermore, kefir contains tryptophan, an amino acid that is a natural sedative and helps promote relaxation and sleep. Tryptophan is a precursor to both serotonin and melatonin, thus playing a direct role in enhancing sleep quality. Consuming kefir can increase the levels of tryptophan in the body, aiding in better sleep regulation.
Anti-Inflammatory Properties
Inflammation is another factor that can disrupt sleep. Chronic inflammation has been linked to conditions such as sleep apnea and insomnia. Kefir’s anti-inflammatory properties, derived from its probiotics and other bioactive compounds, may help reduce systemic inflammation. By mitigating inflammation, kefir can contribute to better sleep quality and overall health.
The kefir sleep connection, in summary …
While more research is needed to fully understand the kefir sleep connection, the existing evidence holds promise as a natural aid for improving sleep quality. By fostering a healthy gut, reducing stress, regulating circadian rhythms, and lowering inflammation, kefir can be an effective natural sleep aid.
Added Probiotic Boost with Gut Healthy Supplements
When I want to give my skin and gut health an extra boost, I add a quality probiotic supplement to my daily routine. One of my go-to probiotics, YourBiology Gut+ contains a powerful mix of 20 Billion CFU probiotics and 10 different strains. Furthermore, it contains 2 prebiotics to help feed all the good bacteria!
I particularly like the addition of digestive enzymes, which helps me with bloating, and so it also features in our best probiotics for women review.
