Did you know that there are over 100 trillion microorganisms in our body? Most of these microorganisms are gut-living good bacteria that work to fight off the bad bacteria and restore balance in our bodies to make us feel better. Unfortunately, there are times when our gut becomes unbalanced with unhealthy levels of certain bacteria causing us to get sick -- this is where probiotics come in.

Why Take Probiotics?

Available in a variety of forms like supplements, probiotics are known to help immune function, nutrition absorption and digestion. They’ve also been shown to help improve mental health conditions, manage digestive problems and lessen the risk of developing common infections in the respiratory tract and gut.

However, it can be overwhelming to pick a probiotic supplement as there are so many brands available today. There’s also the level of live probiotics, the number of CFUs, delayed time-release technology and your specific needs to consider.

To help you out, here's a list of expert-recommended probiotic supplements you can buy online today.
