Why are prebiotics beneficial We all need healthy gut bacteria. We eat junk, take antibiotics, eat food laden with antibiotics, chemicals, and sugar. Our industrialized diet makes it easy for bad germs and yeast to grow in the gut. That's why we eat yoghurt with active cultures and take live probiotics. PROBIOTICS do not survive long in the digestive tract without PREBIOTICS--the FOOD for probiotic bacteria. Remind me why we need the healthy bacteria (PROBIOTICS) To prevent the growth of unhealthy bacteria such as firmacutes and yeasts in adults and children. What is the best way to supply the billions of healthy bacteria to the intestine Take a PROBIOTIC with a PRE-Biotic. this combination is called "SYNBIOTICS" What do these healthy bacteria do stop the growth of germs that cause disease, improve immune function, improve gut function, extract vitamins, minerals and amino acids (building blocks of protein) from food. What is so great about this combination I personally take Essential PRE-biotic, confirmed by 2 independant laboratories to contain LIVE healthy germs. Many of the over the counter brands have inactive, dead bacteria. our Essential PRE-biotic increases the amount of undigestible fibers that STIMULATE the growth of BENEFICIAL bacteria. Is there science to back this up Not only is all this logical, but evidence is mounting that prebiotic/probiotic combinations prevent allergies, boost the immune system, and improve the health of the gut by the direct effects of the biproducts of prebiotics, "short chain fatty acids." Does Dr. Williams take them Yes, every day. She feeds them to her kids, too!
