B longum is a probiotic bacteria that has been studied extensively. There are 32 different strains of B longum that are all considered to be beneficial to our health. It is considered safe and is only known to have minimal side effects.
B. longum has been found to reduce the body’s production of certain chemicals that increase inflammation and oxidative stress. Oxidative stress may be adaptive in the short term to produce extra enzymes that fight infection, but prolonged excessive oxidative stress leads to death of cells, autoimmune disorders, neurologic deterioration, and chronic conditions such as fibromyalgia and chronic pain.
In the literature, the B. longum is gaining attention for its use as an anxiety-relieving probiotic. Its mechanism of action is not completely clear, but it appears to stimulate local intestinal nerves, sending signals to the brain that relieve anxiety. This could also be related to chemical signals produce in the gut, but most studies suggest that the result comes from activation of the enteric nerves themselves. It appears to be particularly effective in certain animal models of colitis.E It is often considered to be classified as a “psychobiotic”.
B. longum is used in two different ways to improve human health: the production of immune stimulating enzymes, and breakdown of complex soluble fiber into smaller components that can be absorbed. As a probiotic, in helps control which other bacteria survive in the gut. Finally, its byproducts of metabolism are absorbed and have systemic effects.
B. longum has received the FDA designation of GRAS (Generally Recognized as Safe).
