Which probiotic is best?

The gut is home to 100 trillion bacteria. There are more bacteria in the belly than cells in the body. This microbiome is responsible for everything from digestion to building a healthy immune system to regulating mental health. When it’s off, a wide variety of conditions can arise, but there are natural ways to heal the gut. Foods such as yogurt, kefir and sauerkraut help feed the good bacteria so that it can thrive, but sometimes you need more help.

Probiotics restore the balance of good bacteria in the gut. They overpower bad bacteria at the root of digestive upset and inflammation.

Florastor and GoodBelly have been producing high-quality probiotics for years, but which one is best?

Florastor probiotic

Florastor is the most clinically researched probiotic in the world. It works to ease symptoms of diarrhea and constipation by temporarily lining the walls of the bowels with live yeast cultures that eventually overpower and replace the bacteria that is making you ill. 

One of its most common uses is as an anti-diarrhea agent. It has also been studied to treat irritable bowel syndrome and inflammatory bowel disease. Florastor also improves lactose intolerance and can be used to treat diarrhea in children. 

Florastor probiotic pros

Unlike other probiotics, Florastor does not contain bacteria. It uses active live yeast to promote gut health and better absorption of food and nutrients. It has been used in over 600 clinical studies and is safe for babies as young as 3 months old.

It meets the gold standard of evidence for its effectiveness in the following ways:

  • Strengthening and maintaining digestive balance 
  • Improving digestion by breaking down carbs and sugar 
  • Surviving the acidic stomach environment
  • Boosting immunity
  • Working well even during  antibiotic use
  • Removing toxins from harmful bacteria

Unlike other probiotics, Florastor does not require refrigeration. 

Florastor probiotic cons

For people who do not tolerate excessive yeast, Florastor can be disastrous, causing uncomfortable bloating, diarrhea and gas. 

It also contains soy and trace amounts of lactose.

This is one of the more expensive probiotic choices, too. It costs around $35 for just 50 capsules.

GoodBelly probiotic

GoodBelly probiotics perform all of the functions that a probiotic is known for. It balances the gut, improves digestion and strengthens the immune system. It’s available in various forms, including juice drinks, supplements, shots, fast melts and yogurt. Each of these forms contains the amount of probiotics needed to achieve the desired effects. For example, one container of yogurts contains the same amount of probiotics as a juice drink.

GoodBelly probiotic pros

GoodBelly is dairy-free and vegan. Each supplement has the recommended number of colony-forming units of one to 50 billion bacteria.

The shots, juice drinks and yogurts have lower sugar than some other probiotics. The number of ways you can take GoodBelly probiotics is a big bonus in general.

GoodBelly probiotic cons

One of the major cons of GoodBelly probiotics is that they do not participate in third-party testing to verify the contents of their supplements. Each supplement only includes one strain of probiotic and does not include prebiotics.  It’s possible that some forms of probiotics include GMO ingredients. 

As with all probiotics, there exists the possibility of side effects that include constipation, diarrhea, bloating and gas. This is especially true for products that have 50 billion CFUs or more.

Should you get a Florastor probiotic or GoodBelly probiotic?

Which probiotic is best depends almost entirely on the symptoms you are experiencing. If diarrhea that prevents you from properly absorbing nutrients in your food is the main symptom, Florastor is the best choice.

However, if you are looking to restore healthy gut balance and want a variety of options to choose from, GoodBelly might work best for you.
