Benefits of taking a probiotic
Probiotics are live microorganisms that help support a healthy gut microbiome.* While your gut naturally contains trillions of beneficial bacteria, factors like stress, diet, travel, illness, and antibiotics can disrupt that balance. A high-quality probiotic can help replenish beneficial microbes and support overall digestive health.*
Research suggests probiotics may help:*
- Support digestive balance and a healthy gut microbiome
- Reduce occasional gas and bloating
- Promote regular bowel movements
- Support immune health (much of the immune system resides in the gut)
- Help restore the microbiome after antibiotic use
Because benefits are strain-specific, the results you experience will depend on the probiotic strains and doses included in your supplement.

How do probiotics help with gas & bloating?
Gas and bloating are often signs that your gut microbiome is out of balance. When beneficial bacteria are depleted (whether from diet, stress, travel, etc.) it can affect how food is broken down and fermented in the gut, leading to excess gas and digestive discomfort.*
Certain probiotic strains have been clinically studied for their ability to help restore microbial balance, support healthy digestion, and reduce occasional gas and bloating.* These strains can work by crowding out less desirable microbes, supporting the breakdown of food, and promoting a healthier gut environment.*
As with all probiotics, these benefits are strain-specific, so it's important to choose a supplement that contains clinically studied strains at effective doses.
How to choose the best probiotic
Not all probiotics are created equal. Here's what to look for when shopping for a supplement:
- Clinically studied strains: The best probiotics identify every strain on the label (genus, species, and strain) and use ingredients backed by human clinical research.
- Effective doses: Look beyond the total CFU count. Each strain should be included at the dose shown to be effective in research—not just a small amount added to inflate the label.
- Quality manufacturing: Choose brands that prioritize ingredient sourcing, testing, and stability. Whether a probiotic is shelf-stable or refrigerated matters less than following the storage instructions provided.
- Minimal fillers: A clean formula with few unnecessary additives is ideal. If the probiotic includes complementary ingredients like prebiotic fiber, those should also be science-backed.

What to avoid
Steer clear of probiotics that:
- Don't disclose complete strain names
- Use proprietary blends without revealing strain doses
- Include clinically insignificant amounts ("fairy dusting")
- Rely heavily on artificial flavors, colors, or unnecessary fillers
How long do probiotics take to work?
Results vary depending on the probiotic strains and your health goals. Some people notice improvements in digestion or regularity within a few weeks, while other benefits may require consistent daily use for a month or longer. Taking your probiotic consistently is key, as many strains work best with ongoing supplementation.
Who should take a probiotic?
A probiotic can be a helpful addition for anyone looking to support gut health, especially if you experience occasional bloating, gas, or irregularity.*
Even if you don't have digestive struggles, a probiotic may help support overall digestive and immune health as part of a balanced lifestyle.*
