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, aids digestion, and helps 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 both maintaining or restoring bacterial balance in the gut. Many fermented foods are a natural source of friendly bacteria. This includes:

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

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

The Best Rated Probiotic Capsules

In our selection of best probiotic brands, we’ve considered price, sourcing, reviews, strains, and colony-forming units (CFU).

  • 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. In general, this is 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. But 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.

1) Best Overall – Culturelle’s Digestive Daily Probiotic Capsules

Culturelle tops our list of best probiotics for several reasons, not least because their capsules are free of milk, wheat, eggs, peanuts, and gluten.

Boasting a 10 billion CFU content, as well as 200mg of inulin, these capsules are intended to support the digestive system. The brand only sells probiotic products; their focused attention indicates that probiotics are an area of expertise.


While the Digestive Daily Probiotic Capsules spearhead their range, there are various other products on offer. Whether you’re looking for IBS support or probiotics with a higher CFU count, you can find it on their site.

Key Features:

  • Strains: Lactobacillus

2) Best Vegan – Doctor’s Best Digestive Health Probiotic

Probiotics are often associated with dairy products; however, there are plenty of premium plant-based alternatives. Best Vegan is proof of that.

The capsules are also soy and gluten-free.

The brand doesn’t publish their CFU content, which is unusual, but they insist that fermenting their prebiotics for at least three years is a superior method.

To maintain full quality control, Dr. Ohhira’s Probiotics are free of artificial additives, chemicals, and animal by-products.

Key Features:

  • CFU Content: N/A

Key Features:

  • CFU Content: 100 billion
  • Strains: Lactobacillus, Bifidobacterium, and 32 more
