Best Probiotics: Our Top Picks

Probiotics are live bacteria and yeasts found in the digestive tract. They are essential in maintaining good gut health, as they help balance the “good” and “bad” bacteria.

While probiotics can be sourced from certain foods, many people are turning to probiotic supplements as a convenient way of fighting harmful bacteria.

However, choosing the best probiotic supplement has become a difficulty in itself. Not only is there a myriad of choices, but selecting high-quality products is a must.

To help you decide, we’ve compiled a list of the best probiotic supplements on the market.

Best Probiotic Supplements: What Are They?

Our gut consists of over 1,000 different types of flora. This colony of microorganisms contains helpful bacteria that support the immune system, aid digestion, and help excrete waste.

However, sometimes imbalances can occur. Too many harmful bacteria can lead to digestive discomforts, such as bloating and stomach cramps, weight change, and fatigue.

That’s where probiotics come in.

As mentioned above, probiotics are a means of maintaining or restoring bacterial balance in the gut. Many fermented foods are a natural source of friendly bacteria. They include:

  • Kimchi
  • Yogurt with live cultures
  • Sauerkraut
  • Miso
  • Kombucha

However, these foods aren’t always accessible or simply aren’t liked in some cases. That’s why probiotic supplements have become a popular alternative.

Please keep reading to find out which brand tops our list for the best probiotic supplements.

The Best Rated Probiotic Capsules

We’ve considered price, sourcing, reviews, strains, and colony-forming units (CFUs) in selecting the best probiotic brands.

CFU: This measurement identifies the number of active microorganisms in each probiotic serving. According to the National Institutes of Health, the average supplement serving contains between 1 to 10 billion CFU. This is generally considered a sensible amount of CFU as too many can cause mild discomfort.

Strains: Specific bacteria species, such as Bifidobacterium and Lactobacillus, are considered more beneficial than other less-known varieties. Therefore, it’s not just a case of how many strains a product contains but which strains a product contains. High-quality products should advertise this.

How to Find the Best Probiotics on the Market

We’re confident that the above represents the best probiotics around. However, if you would like to conduct some research of your own, here are a few tips.

Look for Products with Clinically Studied Strains

Bifidobacterium and Lactobacillus are two of the most effective probiotic species and the most frequently studied. Therefore, probiotics with either or both strains in significant quantities are worth a second look.

There are many other strains, and as you saw above, certain products have over 30. However, not every strain has its benefits backed by detailed research. Please ensure the supplement you buy contains probiotic strains proven to be beneficial.

More Is Not Always Better

A supplement with dozens of probiotics isn’t necessarily guaranteed to be useful. Indeed, a product with four high-quality probiotic strains is better than a product with 40 strains with fewer benefits.

Also, an extremely high CFU count is not always good either. The type of microorganisms in a product is far more important than the number of microorganisms. Supplements with between 5 and 10 billion CFUs may provide the most benefit, although 1-2 billion can prove effective in premium-quality products.

Beware Excessive Ingredients

The best supplements have a low number of additional ingredients. If you see lots of seemingly unnecessary ingredients, consider another product. These extras could consist of sweeteners, dyes, and synthetic fillers you don’t want in your body.

A Word of Caution on Online Reviews

In general, probiotics with thousands of 4+-star reviews usually pass the quality test. However, bear in mind that some companies pay for positive reviews on platforms such as Amazon. Therefore, look at reviews across other sites and perform additional research before committing to any product or brand.

Dubious Claims

If a brand makes outrageous or unverified claims about its products, steer clear. Unfortunately, some unscrupulous companies will make wild claims about certain probiotic strains in their products that aren’t backed by science. There are plenty of reputable companies selling high-quality probiotics, don’t waste time and money on scammers.

What Are the Benefits of Taking a Probiotics Supplement?

In simple terms, probiotics are “good” bacteria that live in the body, helping it maintain a healthy balance. With up to 70% of our immune health lying in our gut, it pays to keep our gastrointestinal (GI) health in check. We will now quickly outline the benefits of regularly taking the right supplement.

Probiotics could:

  • Help balance the “good” bacteria in the digestive system
  • Improve neurotransmitter balance

  • Metabolize heavy metals and xenobiotics
