Probiotic May Help Boost Immune System
When the gut becomes unbalanced with unhealthy levels of certain bacteria, probiotics may help restore the balance. They may also help give your immune system a boost and inhibit the growth of harmful gut bacteria. A new study has found that the probiotic Bacillus subtilis DE111 may help stimulate the immune system.
Forty-four healthy adults with an average age of 41 participated in the study. They received Bacillus subtilis DE111 or a placebo daily for 4 weeks. The researchers measured levels of peripheral blood mononuclear cells (one of the body’s main types of immune cells) at baseline and at the end of the study period. They also measured the response of peripheral blood mononuclear cells to stimulation with bacteria
Participants in the probiotic group saw an increase in anti-inflammatory immune cells in response to the stimulation with bacteria, which indicates a more robust response to boost the immune system. They also saw a decrease in circulating levels of the bacteria, which resulted in reduced inflammation levels.
The study was conducted by researchers from Colorado State University.It was published February 28, 2021 in the International Journal of Molecular Sciences.
