What are probiotics?

Probiotics are beneficial microbes that enhance the body’s digestive processes, support immune function, and promote healthy weight management.* You can receive probiotic benefits from the foods you eat – such as yogurt or sauerkraut – or from probiotic supplements.

What do probiotics do?

The right type and amount of probiotics, meaning the healthy bacteria and yeasts they contain, support your body in several ways – from promoting healthy immune function and successful weight management, to minimizing symptoms like occasional diarrhea, uncomfortable bloating, and constipation.* How do probiotics work? Not all probiotics are the same, nor do they all have the same effects in the body. Different strains of good bacteria can be helpful in different areas. Lactobacillus spp, Bifidobacterium spp, Saccharomyces boulardii, and Bacillus coagulans are the most common beneficial bacteria used in probiotic nutritional supplement products.

What are probiotics versus prebiotics?

The right type and amount of probiotics, meaning the healthy bacteria and yeasts they contain, support your body in several ways – from promoting healthy immune function and successful weight management, to minimizing symptoms like occasional diarrhea, uncomfortable bloating, and constipation.* How do probiotics work? Not all probiotics are the same, nor do they all have the same effects in the body. Different strains of good bacteria can be helpful in different areas. Lactobacillus spp, Bifidobacterium spp, Saccharomyces boulardii, and Bacillus coagulans are the most common beneficial bacteria used in probiotic nutritional supplement products. 

What are probiotics' side effects?

Probiotics are safe in the amounts normally found in food. In general, most healthy adults can safely add to their diet foods or nutritional supplements that contain probiotics. Although some people can experience gas (flatulence) from beginning a probiotic, this generally stops after a few days. If you are lactose intolerant, then you can experience stomach discomfort when getting your probiotics from dairy products. In that case, consider using a dairy-free probiotic. Probiotics are a low-risk way to boost your everyday healthy habits.
