Probiotic supplements: Probiotics are a class of live microorganisms that benefit the host. They colonize the human intestine and promote health, thereby improving the host's microbial balance and exerting beneficial effects. Furthermore, some of the most effective probiotics currently being researched internationally are primarily complex active probiotics composed of multiple microorganisms mentioned above. These are widely used in bioengineering, food safety, and healthcare, and are highly beneficial to human health. It is important to note that when taking these live probiotics, it is best not to take antibiotics concurrently, and be careful not to take them with overly hot water to avoid adverse reactions.
