Research Confirms Probiotics Support Immune System

Jars of fermented foods. Studies show probiotics can help support the immune system.

The past decade has seen a surge in probiotic sales, thanks to an increased scrutiny on the powerful benefits associated with good bacteria. While there are many who cringe at the thought of consuming bacteria, probiotics are actually crucial for the functioning of your digestion, mood, and even bone health. No longer are probiotics being relegated to supporting only digestion. In fact, it turns out these beneficial microorganisms may also support the immune system. Vitamin C used to be the main dietary component attributed to immune support; however, recent reports are showing that probiotics (as well as vitamin D) offer an added benefit. The question is, does your probiotic supplement contain the strains responsible for supporting immune health?

Probiotics: The Key to Immune Health

Keeping your immune system in check ensures that your body is doing a good job in fighting viruses and other foreign invaders known to cause illness. Supplementing with vitamin C may work, but it's not the only piece of the puzzle. In fact, research is showing that probiotics may be helpful in not only preventing but also reducing the duration of certain immune-related conditions. [1] For example, the two strains Lactobacillus rhamnosus and Bifidobacterium animalis may decrease the severity and duration of upper respiratory tract infections. [2] In addition to these strains, Bifidobacterium bifidum and Lactobacillus helveticus may also be helpful for reducing infection risk. [3]

Are You Getting Enough?

Probiotics are quickly becoming a recognized nutrient, simply because their health benefits are so vast and significant. Unfortunately, many people are going without notable consumption of probiotics. Why? Fermented foods are one of the largest food sources of probiotic bacteria, and most people simply aren't opting for raw sauerkraut as their dinner side dish. The easiest way to receive beneficial bacteria is through a high-quality supplement, particularly one that combines a number of different strains. The strains mentioned above (L. rhamnosus, B. animalis, B. bifidum, and B. helveticus) are just a few to look for if you're seeking a way to support your immune system. [4]
