1. Look at the number of live bacteria. At present, many brands of probiotics on the market are misleading in order to induce customers to place orders, and vigorously promote their probiotic activities as high as 30 billion and 50 billion. The more active the bacteria, the better. The key is how many live bacteria reach the stomach? Probiotics are not easy to be killed by acid-resistant, alkali-resistant and oxygen-resistant subcultures, and pass through the stomach in strong acid environment and bile in strong alkali environment. Through multi-layer coating technology, it is easier to ensure that the number of probiotics reaching the intestine does not decrease. Once the probiotics are colonized in the intestine, they will multiply in N power within 20 minutes, which is amazing! So don't blindly choose which so-called highly viable bacteria, and how much they have on the intestine needs to be verified! Even if there are so many living bacteria, they will be ruthlessly excluded from the body if they are not needed! 2. Look at the storage form of probiotics. In March of 20001year, China's Ministry of Health issued [20065438+0] No.84, and Article 10 of the Evaluation Standard for Probiotic Health Food clearly pointed out that it is not recommended to produce live bacterial products of probiotic health food in liquid form. Because probiotics are certified by scientific experiments, it is difficult to survive in liquid, and probiotics are afraid of water. So it is usually preserved in the form of freeze-dried powder. 3. Gastric acid-tolerant probiotics can only play a role if they reach the intestine smoothly and maintain their activity. Prior to this, probiotics were digested by gastric juice, bile and pancreatin, and remained active after reaching the intestine through the digestive tract. Many products failed because of this failure. Therefore, no matter how many live bacteria there are, it is no use being intolerant of gastric acid.
