This brand has never been heard of. You should choose a regular brand.
after the simulated digestion experiments of six products, the survival rate of probiotics is very different, the highest is tens of thousands of times the lowest! The survival rate of some products is close to zero-your baby may only drink a cup of milky "sugar water"!
When babies are growing up, they often encounter problems such as diarrhea, constipation and indigestion. At this time, some people will recommend probiotics to you, saying that it has such benefits for babies, and some pediatricians will also recommend some probiotic products to assist in treatment.
Probiotics generally refer to living microorganisms that can colonize the human intestine and play a beneficial role to the human body. It is a kind of' beneficial' bacteria that can reach the intestine alive after eating and play a role in gastrointestinal regulation. Its main function is to improve diarrhea, indigestion and intestinal flora disorder after taking antibiotics.
The Regulations on the Declaration and Evaluation of Probiotic Health Foods (Trial) issued by the State Food and Drug Administration in 25 clearly stipulates that the number of live bacteria in live probiotic health foods shall not be less than 16 CFU/mL(g) during its shelf life.
that is 1 million CFU/mL(g). That is to say, probiotics must be alive and reach a certain number to be useful.
the measurement of the activity of probiotics mainly includes two aspects: 1. whether it is inactivated during storage and transportation, that is, the amount of live bacteria before taking it. 2. Can you stand the test of gastric acid and reach the intestine alive, that is, the amount of live bacteria after taking it.
first of all, 16 strains of infant probiotics in "Little Red Flower Assessment" were analyzed, and 7 products (products of Kangenbei, Xiuzheng, Lactobact, Childhood, Synbiotics, OptiBac and Lifespace) did not meet the requirements.
After that, "Little Red Flower Evaluation" finally selected six probiotic products for laboratory testing.
the test is divided into two steps: one is to test the live bacteria quantity of probiotic products before taking them to see if they can meet the national standards. The second is to test the number of viable bacteria left in the product after taking it.
from the product packaging, the six products submitted for inspection are all nominally containing billions of live bacteria. And the added strains are Bifidobacterium and Lactobacillus, both of which belong to lactic acid bacteria, so the total number of probiotics in the product = the number of lactic acid bacteria.
So, can their viable count meet the national standard?
After testing, it was found that the total amount of viable bacteria contained in the six products before taking them within the warranty period met the national standards. In particular, Kangcuile leads with the total amount of lactic acid bacteria of 1.3 * 11 cfu/g..
Tomson Bianjian (13.56, .5, .37%) probiotic solid beverage, because only the factory quantity of live bacteria is marked, and the loss of probiotics during transportation and sale cannot be predicted, the measured value of live bacteria is lower than the factory quantity.
Simulated digestion experiment: there is a huge difference in the number of live bacteria
The most important thing for probiotics is the survival rate in the baby's body, and how much it can play after being scattered around the stomach depends on the number of live bacteria. So the next step is to test the survival rate of six products after taking them.
Due to the limited conditions of human experiments, the "Little Red Flower Assessment" designed an in vitro simulation experiment of human beings with reference to relevant scientific research literature. The probiotic products were diluted 1 times, adjusted to pH 3., and kept at 37℃ for 1.5 hours to detect the survival rate.
After the simulated digestion experiment, the difference of probiotic survival rate is wide, the highest is more than 5, times of the lowest:
Only one product of Tomson Bianjian has a probiotic survival rate of more than 1%, and its probiotic survival rate is 38%; Kang Cuile, known as "the number one in global sales", ranked first in the number of live bacteria before taking it, but the survival rate after the simulation experiment was only .67%.
The live bacteria of the well-known brand Synbiotics Children's Probiotics Powder were almost wiped out by the whole army. The nominal 3.9 billion live bacteria were only 3,6 after simulated stomach digestion.
if the shelf life required by the state is ≧ 1 million live bacteria as a reference value, the number of remaining live bacteria in English and Synbiotics products is too small, which may be useless.
It should be noted that this simulation experiment only simulates the environment of baby's stomach digestion from three aspects: temperature, pH value and digestion time. In real human digestion, there are also effects of stomach digestive enzymes, bile and intestinal digestion.
It can be said that the real digestive environment is worse than this in vitro simulated environment, and the number of remaining live bacteria should be even less.
As the survival rate of Synbiotics is close to %, I'm afraid that babies may only drink a cup of milky "sugar water"!
