Well, let’s say that you have bloating, gas, loose stool, or constipation, these are signs that you should try taking a probiotic that you can ingest for the stomach or the intestinal tract. What you’ll find is that the probiotic will help to ease those symptoms. Another sign that you might need a probiotic that is not as obvious is if you are experiencing allergies and asthma. The studies show that taking probiotics help to ease the symptoms of allergies and asthma.  For those that suffer from inflammation in the joints, and inflammation of the skin, there are probiotic supplements for topical use. Gum disease, bleeding gums, and cavities are all signs of disbiosis, or a disturbance in the microbiome - and for this a probiotic is recommended. The studies on probiotics have grown exponentially in the last few years. If you have any questions about when to take a probiotic, or if you should be taking a probiotic, please tweet me @askdrsanda.
