Introduction to Probiotic Supplements

Probiotics are healthy microorganisms that line your intestinal walls, promoting balance in the microbiome and improving digestive health. The result is more regular bowel movements and the elimination of symptoms like bloating and diarrhea.

The market is full of many and varied probiotic supplements containing different strains as well as additional organic ingredients to improve gut wellness. Some are more potent and effective than others, but how do you know the difference? Learn how to select the best brand, and to discover our top choices for the best natural probiotics on the market.

What Factors Lead to Poor Gut Health?

There are a whole host of factors that can contribute to poor gut health, including chronic stress, a poor diet, intolerance to certain foods, medical conditions like diabetes, or imbalances in the gut bacteria. Hormonal imbalance or an endocrine issue can often affect the digestive system, as can abdominal surgery.

What Are the Benefits of Taking a Probiotic Supplement?

Benefits

  • These supplements can promote regular bowel movements.
  • They can eliminate symptoms like gas and constipation.
  • Probiotic supplements can help strengthen the immune system.
  • They promote a healthy gut microbiome.
  • Probiotics can enhance overall digestive wellness.

How Do Probiotic Supplements Work?

These supplement include various different strains, depending on the product. Generally speaking, these are healthy strains of bacteria which line the intestine walls, destroying bad bacteria and promoting a healthy microbiome.

This helps promote regular bowel movements and eliminate symptoms like gas and diarrhea. An article published in Tropical Life Sciences Research discussed the best health features of probiotics (1).

However, specific strains have other benefits, including lowering cholesterol, decreasing anxiety, supporting immune health, and decreasing the risk of developing certain gastrointestinal conditions.

Probiotics are high in antioxidants, which eliminate free radicals and lower oxidative stress. This can repair damage to the digestive tract and protect it from potential harm. They have anti-inflammatory agents which can decreases gastrointestinal swelling and bloating.

Many probiotic supplements contain additional ingredients like fiber, which helps absorb liquid from the intestines and promote more regular bowel movements. It may also fill up your stomach, suppressing appetite and helping with weight loss. The Mayo Clinic discusses why dietary fiber is essential for a healthy diet (2).

What Are Probiotic Supplements Made From?

Here are some of the primary active probiotic strains:

Bacillus – This strain can enhance digestion and promote a healthier gut microbiota in human beings and animals. They have antimicrobials which kill damaging bacteria, and they support a strong immune system (3). An article in the Journal of Food Science and Technology examined the importance of the gastrointestinal life cycle of bacillus for probiotic functionality.

Lactobacillus – These are lactic acid bacteria which line the small intestines and vagina, killing bad bacteria and promoting digestive health (4). In addition, they assist in the absorption of minerals in the body. An article in the Journal of Clinical Pathology discussed the mechanisms and therapeutic effectiveness of Lactobacilli (5).

Bifidobacterium – This strain exists in the microbiota, promoting digestive health and eliminating bad bacteria. One of their main roles is to digest fiber, and they also play a key role in preventing infections. An article in Frontiers in Microbiology discussed the role of this strain in the human intestines (6).

How Do You Choose a Probiotic Supplement?

Before you select a probiotic to purchase, it’s important to do your own evaluation of the brand. These are some of the key features to keep in mind when making your selection:

Ingredients – Probiotic supplements contain a number of different strains, each of which has a different purpose in gut health. There may also be other organic ingredients which promote digestion like fibers.

Research the ingredients carefully to make sure the product is right for you. According to Dietitian Lauren Manaker, “It’s important to make sure that any probiotics that you buy contain the strains your body needs and in the right quantities (8).”

Safety – Ensure that there are not potentially harmful chemical or artificial additives, which could lead to side effects. In addition, make sure the manufacturer follows strict safety guidelines, ideally GMP, and produces the products in an FDA-registered facility.

Manufacturer – It’s always best to purchase from a known and reputable manufacturer, as they are more likely to be trustworthy. Certainly look into the background of the company when evaluating products.

Reviews – Customer reviewers are a great source of information about a supplement, its benefits, and its limitations. Read through a number of reviews before you make your final choice.

Satisfaction Guarantee – Any company which has faith in its product will give you enough time to try it out before deciding if it really works for you. Look for a brand that has at least a 30-60 day guarantee.

Cost – These supplements come in a range of prices, with the average being somewhere from $20-40. Compare the cost of different brands with what they offer to decide whether a supplement is worth it.

Product Comparison – Do look at a number of different brands and compare them in terms of cost, ingredients, benefits, guarantee, and other relevant features.

What Are Some Natural Ways to Enhance Digestive Health?

Probiotics are very helpful in supporting digestive health. Alongside taking a supplement, there are also some lifestyle modifications you can make to improve your gut wellness. Consider incorporating some of these into your routine:

Drink Water – It’s important to take in enough fluids during the day. One of the symptoms of dehydration is constipation, so you want to make sure you take in fluids through fruits and veggies, as well as water rand other beverages.

Limit Stress – Stress can lead to many physical issues, and some of them are constipation, diarrhea, and other digestive symptoms. If you work on decreasing your anxiety, your gut health should improve. Consider taking some time off, spending more time with family and friends, participating in a zoom yoga or meditation class, writing in a journal, or seeking therapy.

Modify Your Diet – Eat whole foods that are healthy and do not contain sugar, processed items, or unhealthy fats. These are detrimental to your digestive system and are better left in the past.

Try some of the best probiotic foods, like yogurt, miso, kefir, and pickles. Consume plenty of fiber to promote regularity and omega-3 fatty acids to help the absorption of nutrients. Include probiotic fruits and probiotic vegetables.

Exercise – Working out on a regular basis can give digestive health a boost, by assisting in pushing the food through the intestines. It can ease constipation and may also decrease inflammation.

Moderate Smoking and Drinking – Smoking and drinking can have a detrimental effect on digestion. If you’re having gut issues, it’s best to try to limit or even quit these habits so as not to exacerbate your gut. The good news is quitting can effectively reduce your symptoms.

Sleep Well – Getting a quality sleep is important for overall health and cognitive functioning, mood, and it also plays a key role in gut health. It’s very important to get an adequate, quality rest every night.

A study in mice published in PLOS ONE found that disruption of the circadian rhythm affected the intestinal microbiota (7).

Frequently Asked Questions (FAQs)

Q: Do Probiotic Supplements Work?

A: Yes, probiotic supplements for gut health actually do work. According to Harvard Health Publishing, there is research supporting the benefits of probiotics in digestion starting from the mid-1990s (9). Naturally, the selection of strains is important, and these products will work different for each individual. But generally speaking, they do tend to be effective.

In the words of NYU Langone Health gastroenterologist Roshini Rajapaksa, M.D. “The last several years have seen an explosion of research on the importance of the microbiome and the many health benefits associated with a balanced one. Probiotic supplements offer a way to help maintain this balance (10).”

Q: Where Can I Buy Probiotic Supplements?

A: Generally speaking, probiotic supplements are for sale from a number of online retailers as well as in shops like pharmacies and health food stores. For a specific probiotic, you have to research the brand online.

Q: What is the Most Effective Probiotic Supplement?

A: In this article, we presented you with 14 of our favorite probiotic brands and included detailed information about each. They are all very effective supplements, and we would recommended that you select one of them based on your preference and the information given.

Q: Can Probiotic Supplements Cause Bloating?

A: It’s possible that you may have some bloating, diarrhea, and other mild digestive symptoms in the first couple of days after taking a probiotic supplement, however, these will disappear once the product cleanses your system.

Q: Are Probiotic Supplements Safe?

A: Probiotics alone are safe and may only lead to mild digestive symptoms for a couple of days after taking them. However, for any product you purchase it’s important to look at the entire ingredients list including inactive substances to ensure there are no harmful chemical or artificial additives.

It’s also crucial to look into the safety practices of the manufacturer. Ideally they should product their products in an FDA-approved facility using GMP standards.

Q: Can Probiotic Supplements Cause Acne?

A: The vast majority of the time, probiotics do not cause acne and may even help eliminate it. If you have a gut infection while on probiotics, one of the effects could be breaking out in acne. If this happens, stop taking them until you resolve the issue.

Q: Who Needs Probiotic Supplements?

A: Probiotic supplements are suitable for any adult who wants to improve their overall digestive health, or for those who are going through a bout of symptoms like diarrhea or bloating and want to resolve it. These are for users who are looking for a natural, organic solution rather than medication from a physician.

Q: Are Probiotic Supplements Vegan?

A: Some brands are vegan, but not every probiotic product suits this diet. Make sure to check the label to ensure that this is a brand you can consume.

Q: Are Probiotic Supplements Necessary?

A: No, they are not actually necessary, because the probiotic bacteria is a natural part of your microbiome and is there to balance the gut flora and promote proper digestion. However, sometimes the gut gets out of balance, and it’s helpful to take a probiotic product to restore balance to the microbiome.

Gail Cresci, Ph.D., is a registered dietitian and microbiome researcher. She explains that probiotics, “can help us digest food we can’t digest [naturally]. We don’t have enzymes to break down and absorb certain fibers. Probiotics release metabolites, which are beneficial byproducts that help us digest them (11).”
