Gut health, probiotics, microbiome, optimization, second brain, prebiotics…is your head spinning yet?

Gut health is important, this we know. But figuring out the best way to optimize it is? Well, that’s a different story and it’s certainly not a cut-and-dry answer.

We’ve been inundated with information lately about our gut health and how we need to be taking care of it, and while this is certainly valid and an absolute positive, there’s just too much information for most of us to comprehend.

I recently spoke with a health professional with a specialization in the area of gut health and he introduced me to the idea of a synbiotic supplement. He explained to me why the best probiotic supplements are the ones that also contain a prebiotic and potentially even a postbiotic, too. 

What he unveiled made a lot of sense, so I went ahead and found the best prebiotic and probiotic combination supplements on the market and am sharing them here with you, while also passing along a little bit of the knowledge that was imparted to me.

Quick Ranking of Our Top Picks

An Introduction to Prebiotics, Probiotics, and Your Gut Health

gut health probiotic prebiotic

Without going too far into the weeds, let’s do a brief overview of your gut and the roles of prebiotics and probiotics.

The lining of your gut is covered with microscopic organisms, mostly bacteria. These organisms create an ecosystem that we refer to as the microbiome. Although we are totally unaware of it, there’s a lot going on and it plays a critical role in your health, mood, and behavior.

What you feed your microbiome by way of the foods you eat and the supplements that you take can have a huge impact on the health of your gut microbiome. And it goes without saying that the healthier you are, the healthier your microbiome will be. The key to a healthy gut is to nourish the nearly 1,000 different species of bacteria that you’ll find in there.

There are two ways to do this - you can help the microbes that are already there to grow by giving them the food they like, which are prebiotics. Or, you can add living microbes directly to your system, which is probiotics.

What Are Prebiotics?

Prebiotics are specialized plant fibers that act like fertilizers to stimulate the growth of healthy bacteria in your gut. These are found in many fruits and vegetables, particularly those that contain complex carbohydrates. These carbs do not digest by your body, which means that they pass through your digestive system to then become food for the bacteria and other microbes in your gut.

What Are Probiotics?

Probiotics are live organisms which are typically specific strains of bacteria that directly add to the population of healthy microbes in your gut. Similar to prebiotics, you can get probiotics from the food that you eat, for example, yogurt. Probiotics make their way to your gut where they begin to live and colonize and, ideally, start to optimize your health.

Do You Need Both (Prebiotics and Probiotics)?

Yes, your gut needs both prebiotics and probiotics to function properly. Since prebiotics serves as food for probiotics, the organisms in your gut need access to prebiotics in order to operate optimally. Scientists have yet to determine whether or not taking prebiotics can effectively support the growth and development of probiotics, though.

If your diet is lacking in nutrients that contains a healthy selection of both prebiotics and probiotics, you might consider supplementing with a prebiotic and probiotic combination, we’ll get to our top picks next.

What to Look for in a Prebiotic and Probiotic Supplement Combination

Before we get into our top choices, let’s highlight some factors that you should consider as you choose which option is best for you.

taking probiotics and prebiotics

CFUs

CFUs stands for colony forming units and it’s a unit of measurement used to determine the number of bacterial cells in a probiotic supplement. Counts are measured in the billion and can range from 2 billion to 75 billion. In general, there is no hard and fast rule for CFUs. Some people find that they experience more adverse symptoms with higher CFUs and don’t have enough benefits with lower CFUs, so choosing a mid-range CFU count is usually a safe bet for most active adults.

Strains

There are thousands of bacteria strains to choose from. Look for a supplement that contains clinically studied and clinically proven bacteria strains.

Refrigeration

Some strains need to be refrigerated to protect their integrity, which needs to be taken into consideration as these might not be as easy to take on the go. However, there are some brands that offer probiotic and prebiotic supplements that are safeguarded by a moisture-controlled capsule that doesn’t require refrigeration.

3rd Party Testing

As with any supplement, you should be seeking a prebiotic and probiotic combination supplement that’s been rigorously tested by a third party to ensure safety and efficacy. Testing is not required, however, integral brands will have a testing procedure in place to ensure that you’re always getting the best quality, most effective product possible.

Brand Integrity and Reviews

Pay close attention to the brand itself and what its customers (or lack thereof) are saying about its products. Sometimes you have to be your own judge and trust your gut, no pun intended, but do your due diligence and a little sleuthing to make sure you’re working with a brand that you can trust.
