The term “probiotic” gets tossed around a lot in wellness circles, but what are they really and are they worth the hype? According to the World Health Organization, probiotics are “live microorganisms which, when administered in adequate amounts, confer a health benefit on the host.” In simpler terms: probiotics are beneficial bacteria (and sometimes yeasts) that can support your health when taken in the right strains and doses.

Probiotics are found naturally in fermented foods like yogurt, kefir, kimchi, and sauerkraut, but they’re also available as dietary supplements. Not all probiotics are the same, and their benefits depend on the specific strains used. That’s why healthcare professionals recommend choosing the right type and dose for your unique needs. Here are 8 reasons why people, under the guidance of a health professional, consider adding probiotics to their wellness routine:

1. They Can Help Prevent Antibiotic-Associated Diarrhea

Antibiotics can wipe out harmful bacteria, but also the beneficial ones in your gut. This disruption often leads to diarrhea. Certain probiotic strains, such as Lactobacillus rhamnosus and Saccharomyces boulardii, have been shown to reduce the risk and severity of antibiotic-associated diarrhea by restoring microbial balance.

2. They Support Digestive Health

From bloating to irregularity, digestive issues are common. Research suggests some probiotics can help manage symptoms of irritable bowel syndrome (IBS), support remission in inflammatory bowel disease (IBD), and even improve lactose digestion for those who are lactose intolerant.

3. They May Strengthen the Immune System

Since much of the immune system lives in the gut, probiotics play a role in helping regulate immune responses. Studies show they may reduce the risk of respiratory tract infections, stomach bugs, and even lessen symptom severity when illness strikes.

4. They May Benefit Skin Health

The gut-skin connection is an area of growing interest. Some studies suggest probiotics might help with conditions like acne or eczema by reducing systemic inflammation and supporting skin barrier function.

5. They Can Support Liver and Brain Health

In people with liver issues, probiotics may help reduce ammonia levels and oxidative stress. Also, early research on the gut-brain axis shows that certain strains, sometimes called “psychobiotics,” may positively influence mood, stress, and cognitive function.

6. They May Assist in Managing Helicobacter pylori

H. pylori is a bacteria that can cause ulcers and stomach discomfort. Certain probiotics, such as Lactobacillus reuteri, may reduce H. pylori levels or improve the effectiveness of conventional treatment while minimizing side effects.

7. They Help Reduce Inflammation

Chronic, low-grade inflammation is linked to many long-term health issues, from heart disease to metabolic syndrome. By supporting gut barrier integrity and balancing immune responses, probiotics may help reduce inflammation throughout the body.

8. They Can Support You Through Life Changes

Whether it’s travel, stress, illness, or dietary shifts, your gut microbiome can get thrown off balance. Probiotics may help stabilize it during these transitions, acting like an “insurance policy” for gut health.

The Bottom Line

While probiotics offer exciting benefits, they aren’t a one-size-fits-all solution. The right strain, dose, and timing depend on your health needs, and not everyone benefits in the same way. In some cases, especially if you’re immunocompromised, probiotics may even pose risks. That’s why it’s important to consult with a healthcare professional before adding probiotics to your routine. They will help you determine whether probiotics are appropriate, and if so, which strains and products are most likely to be effective for your goals.
