Diarrhea can make you feel awful. In addition to running to the bathroom constantly‚ you may experience abdominal pain‚ cramps‚ and bloating; you might even run a fever! To make matters worse‚ the source of your condition can be unpredictable. Foods‚ illness‚ stress‚ and medications can all cause diarrhea. However‚ one of the biggest causes of diarrhea is bacteria.

Harmful bacteria may infect food that has been left out too long without being refrigerated. Some commonly affected foods include raw meat‚ shellfish‚ and eggs. When you eat these tainted foods‚ bad bacteria enters your digestive tract and makes you sick‚ potentially causing diarrhea or vomiting. To protect yourself from contaminated foods‚ you should always cook foods thoroughly‚ refrigerate them promptly‚ and wash your hands and counter surfaces after handling raw meat.

However‚ despite taking these precautions‚ bacteria can still find a way into your system. A common treatment for diarrhea caused by bacteria is antibiotics. However‚ if you’re a woman‚ antibiotics may sometimes contribute to yeast infections. Klaire Labs’ Saccharomyces Boulardii is a natural supplement that can help relieve the symptoms of diarrhea. Each vegetarian capsule contains saccharomyces boulardii‚ which is a probiotic (friendly fungus) that fights harmful organisms in your stomach; your gut needs to have a balance between various types of bacteria‚ which this supplement helps restore.

Saccharomyces Boulardii capsules also provide L-leucine‚ an amino acid that supports your immune system and helps fight off infection. Each bottle contains 120 capsules‚ which should last for about two months if you take the recommended dosage of two capsules per day.

Klaire Labs is a leader in providing hypoallergenic probiotics‚ and has been serving health care professionals for over 40 years. Its supplements are free of gluten and dairy. The company regularly partners with researchers and clinicians to formulate products ideal for patients that need gastrointestinal support.

      from HEMET CA on 3/18/2020
      My dogs were diagnosed with intestinal dysbiois by an internal medicine veterinarian. He prescribed this, plus another probiotic and an antibiotic to combat it. Their runny stools cleared up in less than 2 weeks! They stay on the probiotics until they get rechecked in 2 months.

      Pros

      It can be stored at room temperature..It must be tasteless because my dogs don't mind it when sprinkled on their lunch meal.

      Cons

      Hard to tell if Saccharomyces Boulardii by Klaire Labs  does support the elimination of candida.
