Although more research is necessary before your doctor is likely to prescribe these beneficial bacteria to treat your hay fever, probiotics may be a viable way to reduce the symptoms of seasonal allergies.
The theory is that living in a super clean environment has resulted in many of us not coming in contact with much bacteria and microbes. As a result, our immune systems go crazy when the encounter allergens, even if they’re harmless. Probiotics are microbes that promote beneficial bacteria growth in the intestines, potentially easing the body’s reaction to foreign allergens.
The study was conducted by researchers at Vanderbilt University in Nashville, Tennessee. They conducted 23 different studies with over 1,900 participants. Seventeen of the studies reported that people who suffer from seasonal allergies improved in at least one way after taking probiotic supplements, as opposed to people who took a placebo (fake medicine).
