Probiotics can be taken dry, but are not recommended. Probiotics generally refers to a class of microorganisms that are beneficial to the human body, usually acting on the human intestinal tract to maintain the balance of human intestinal flora. It promotes digestion and absorption to maintain intestinal health. If you take it dry, it may not be dissolved and lubricated by water, resulting in probiotics remaining in the throat or esophagus, and not reaching the intestines well, which reduces their effect. Generally speaking, probiotics are very widely used, and can be used for food additives, such as yeast, etc., and pharmaceutical preparations, such as bifidobacteria and lactobacillus. When using pharmaceutical preparations, they are usually taken with warm water, or dissolved in warm water at about 35 degrees Celsius and then consumed. It is important to note that if you are taking probiotic pharmaceutical preparations, you need to follow your doctor’s instructions. In addition, the human body flora is a state of dynamic balance, not the more probiotics the better, so the intake should not be too much, so as not to aggravate the burden on the stomach and intestines.
