If you have allergies like allergic rhinitis, or hayfever, you may dread spring. You may know spring is here long before the pollen thickly blankets your car each year.
Allergies are Increasing
Allergies are increasing in western cultures. Up to 20% or more of the population is thought to have allergies of one kind or another and rates are rising [1,3]. Allergies have a genetic component but also researchers theorize there is an environmental component. There is even a name for the progression in children of allergies from eczema to allergic rhinitis to asthma: “the pediatric allergic march” .
One hypothesis for why this is occurring is called the “hygiene hypothesis.” The hygiene hypothesis is the idea that our western culture’s decreased exposure to microbes, increased use of antibiotics, antimicrobial products and residence in increasingly urban environments has created an overly ‘clean’ environment that has resulted in a human microbiome that is generally less diverse and stimulated. This decrease in both stimulation and diversity, it is hypothesized, may be disrupting the way our immune system should work [1, 5].
Infants that present allergies early in life are known to have altered gut microbiota . Your gut microbiota is all the bacteria that live in your digestive tract. Each person has trillions of these little guys and they play a significant role in our immune function.
Bifidobacterium and Lactobacillus are the most studied probiotics strains.
Bifidobacterium lactis, Lactobacillus paracasei and Lactobacillus acidophilus are three oft studied strains all of which are found in H2PROTM. Mostly probiotics are administered orally and are generally safe, though immunocompromised patients should check with their doctor.
The approach of current research varies, so some researchers look at strain specific results while others look at the benefit of multi-strain effects . The specific way probiotics work to modify the allergic response is still mostly a mystery and likely highly complex . However, studies have shown that immune response in patients can be modified by the use of probiotics [1,2,3,4,5].
Probiotics and Hayfever
Hayfever includes nasal congestion and itchy watery eyes. It is an atopic disease, or allergy, that is related to a hypersensitivity of the immune system. Other allergic afflictions include allergic asthma and atopic dermatitis and eczema.
One study published in the European Journal of Clinical Nutrition found that allergic rhinitis symptoms were mitigated during seasonal exposure by administration of B. lactis . In 2014, a study found that adults suffering from chronic hayfever, significant enough to consistently compromise their quality of life during grass pollen season and who took L. paracasei had an improved quality of life. Patients reported improved eye comfort even if nasal symptoms remained unchanged.
Other studies have shown a preventative benefit of probiotics for children at high risk of allergy  although there are some mixed results. In any case, though the evidence for the prevention of allergy is high through the use of probiotics even as research begins to tease out what strains and doses are effective.
Take H2PROTM daily for seasonal allergy support.
We do know that doses of probiotics between 1 and 10 billion CFU have been shown in studies to be effective. Doses of even 1 billion CFU have shown effects in some trials. H2PROTM contains 7 billion CFU of four strains of Lactobacillus and Bifidobacterium in a great tasting powder fortified with vitamins to optimize your health and wellness.
Support your immune system and help beat allergies with H2PROTM probiotics and vitamin powder. It is formulated for everyone, we even have a dosing chart for kids!
Don’t let seasonal allergies get you down! #LoveYourGuts
