Best Probiotics Supplements for Low Carb Keto Diet

If you love bacon and cheese, you’ll surely believe that the keto diet is the bomb!

But as you enjoy eating as much meat as possible, you’ll tend to neglect the foods that the good bacteria in your gut needs.

Eventually, this will result in an imbalance in your gut microbiota.

What does this mean for you?

Well, it could cause a wide array of health issues (and mind you, these issues aren’t easy to deal with).

It will often start with a mild symptom like stomach pain or gastric discomfort.

But wait, let us tell you something.

Symptoms will start to get pretty ugly fast if you don’t treat it right away.

Before you know it, you already have bad breath, diarrhea, constipation, difficulty urinating, depression, and many more(1).

If you don’t want to be in such an ugly situation, there’s one thing you can do—take more probiotics.

These contain live bacteria that can fight off the bad bacteria in your gut and restore your microbiota’s balance.

When you take these pills, you won’t just manage the symptoms mentioned earlier.

You can even boost your gut health and immune system and enjoy the keto diet’s weight loss and health benefits to its fullest.

So here we go!

How to Choose Probiotics For Your Keto Diet

Without a doubt, taking probiotics supplements can help improve gut health.

Despite this fact, many people on the ketogenic diet don’t prioritize taking this type of supplement because of one simple reason—they don’t know which one to choose.

Once you check out the options in the market, you’ll understand why.

With the vast array of keto probiotics in the market, it can be overwhelming and intimidating to determine which one to take.

The great way to address this is to equip yourself with the right buying information.

That’s what we’ll talk about. Below are some of the keto probiotics buying considerations that you should think about:

Live Strains

Once your doctor has given you the signal to take a probiotic supplement, ensure that the ones you will choose contain live strains of the yeasts or bacteria.

Additionally, make sure that the company guarantees the life of these strains at the time of use and not just during the time of manufacture.

Type of Probiotics

You need to understand that the science of probiotics is relatively new, so not enough research is conducted to determine which strains are the best. (2)

Based on the available information we have regarding this supplement, each strain can provide different benefits.

According to the available studies on probiotics, some of the strains to look for to maintain good digestive health are B. longum, B. lactis, B. animalis, S. cerevisiae, and lactobacillus.

These probiotics have shown promise in reducing the signs and symptoms of constipation, which are prevalent for people on the keto diet. (3)

On the other hand, the strains that may effectively promote weight loss are B. lactis, L. gasseri, and L. rhamnosus. (4)

When choosing your probiotics, we recommend that you go for ones containing a probiotic blend containing as many strains as possible.

Preferably, Bidifdobacterium, lactobacillus, and Saccharomyces boulardii because these are the most well-researched strains. 

Probiotic Content (Number of organisms present in each dose)

You can easily find the information on probiotic content at the supplement’s packaging.

It’s often referred to as CFU (Colony Forming Unit).

The general recommendation is to choose a probiotic supplement that contains at least 1 billion colony forming units in one dose. 


As mentioned, this area of research needs further studies.

On top of that, there are no federal standards for probiotic supplements in the US. 

Because of this, it’s recommended that you pay attention to the supplement’s manufacturer. 

It’s recommended that you choose a brand-name probiotic with research that can back their effectiveness.

The more reputable the company is, the more likely it is that their products have been tested and properly studied.

Expiration Date

Keep in mind that probiotics contain live organisms, so it’s a must that you take them before their expiration date. 

If you plan to buy the supplement in bulk, ensure that the expiration date is still far away.
