As research continues to suggest that different strains of probiotics may support different aspects of our health, more and more personalized supplements pop up on store shelves. Given the trillions of bacteria in our microbiome, though, it can be tricky to figure out which probiotic supplement is best for your needs.

“In general, gut health is important in that it plays a role in many different bodily functions,” says dietitian Kelly Jones M.S., R.D., C.S.S.D., L.D.N. “These include digestion, immunity, vitamin and mineral absorption, hormone regulation, and mental health.”

The right probiotic can make a big difference—as long as you choose your strains and amounts carefully. Here’s how.

Identify Your Unique Issues

A balanced, diverse gut microbiome typically leads to overall better health. In an imbalanced microbiome (called dysbiosis), however, ‘bad’ microbes take over. Often, this leads to gastrointestinal and regulatory distress, Jones says.

One tell-tale sign that you need to up your gut game is constipation. “Many people experience constipation,” Jones says. “However, those who suffer from chronic constipation may benefit from probiotic supplementation.”

Or, you might find yourself on the other side of the gut distress spectrum: diarrhea. Probiotics may help here, too, Jones suggests.

“There are many different causes of diarrhea, but research shows that probiotic intake has been shown to combat the severity of diarrhea related to many different causes,” she says.

Other health concerns a probiotic may support: overall immunity, brain health, mood, energy, weight management, and more.

Target Your Needs

Once you know what health concerns you want to address, it’s time to choose the right probiotic.

Since different bacteria strains live in (and impact) different parts of the body, your supplement should contain strains that match your needs.

Additionally, consider how many CFU (colony forming units) a supplement contains. “Typical dosages vary based on the product,” says Jones. “But they typically range from 5 to 10 billion CFUs for children and 10 to 20 billion CFUs for adults.”

Since we all have different gut bacteria, start with a brand that contains many different probiotic strains. Supplements work differently for different people, depending on their individual microbiome. Be patient and you’ll find the variety that works best for you!
