Probiotics: What They Do and How to Use Them

Probiotics are live bacteria and yeasts that can help your gut work better. You’ll find them in fermented foods and supplements. They don’t fix every digestive issue, but used right they can ease bloating, shorten some bouts of diarrhea, and support digestion after antibiotics.

Which strains do what

Not all probiotics act the same. Here are a few reliable choices and what they’re most often used for:

Lactobacillus rhamnosus GG (LGG) — helpful for shortening the duration of acute pediatric diarrhea and reducing risk of some infections. Good for adults with occasional stomach bugs too.

Bifidobacterium species — often used for general gut balance, easing constipation, and improving stool consistency.

Saccharomyces boulardii — a yeast probiotic that reduces antibiotic-associated diarrhea and can help travelers’ diarrhea. Because it’s a yeast, it works when bacterial probiotics might not.

Lactobacillus acidophilus — common in yogurt and many supplements; useful for mild digestive support and sometimes for reducing bloating.

How to pick and use a supplement

Start with a clear label. Check the strain names (species + strain), the total colony-forming units (CFU), and the expiration date. A typical daily dose ranges from 1 billion to 10 billion CFU for general support; some conditions call for higher doses (20–50+ billion) under medical advice.

Look for products with specific strains listed (not just “proprietary blend”). If you want help with antibiotic-associated diarrhea, choose S. boulardii or an LGG product. For constipation or regularity, products with Bifidobacterium can be better.

Take probiotics with food unless the label says otherwise — food can protect the microbes as they pass through stomach acid. If you’re starting after antibiotics, begin while you finish the antibiotic and keep going for 1–2 weeks after; some people continue longer for maintenance.

Expect subtle changes. Some people notice reduced gas and better bowel consistency in 1–4 weeks. Others may feel nothing. Mild side effects like gas or bloating early on are common; they usually fade in a few days. Stop and ask a doctor if you get a fever, severe stomach pain, or if you are immunocompromised — people with weakened immune systems should avoid over-the-counter probiotics without medical approval.

Prefer food first? Try plain yogurt with live cultures, kefir, sauerkraut, kimchi, miso, or tempeh. These give probiotics plus nutrients and are an easy, low-risk way to support your microbiome.

If you’re unsure which product to try, talk to a pharmacist or your healthcare provider. Keep expectations realistic: probiotics help in specific situations, not as a cure-all. Small, consistent steps—picking the right strain, dose, and timing—make the biggest difference.
