Probiotics
How to Use It
The amount of probiotics necessary to replenish the intestine varies according to the extent of microbial depletion and the presence of harmful bacteria. One to two billion colony forming units (CFUs) per day of acidophilus is considered to be the minimum amount for the healthy maintenance of intestinal microflora. Some Saccharomyces boulardii research has used 500 mg taken four times per day. Preliminary research suggests that combinations of probiotic strains are in some cases more effective than individual strains,” but additional research is needed to confirm that possibility.8
Where to Find It
Beneficial bacteria present in fermented dairy foods—namely live culture yogurt—have been used as a folk remedy for hundreds, if not thousands, of years. Yogurt is the traditional source of beneficial bacteria. However, different brands of yogurt can vary greatly in their bacteria strain and potency. Some (particularly frozen) yogurts do not contain any live bacteria. Supplements in powder, liquid extract, capsule, or tablet form containing beneficial bacteria are other sources of probiotics.
Possible Deficiencies
People using antibiotics, eating a poor diet, or suffering from diarrhea are more likely to have depleted colonies of friendly bacteria.
Best Form to Take
While there are many probiotic strains used in supplements, there have been relatively few comparison trials studying whether certain strains are more beneficial than others for a given condition (although, there have been numerous clinical trials showing a benefit for at least one type of strain). However, it does appear that, under normal conditions, different types of bacterial flora occupy different parts of the body, and some strains may have a beneficial effect in specific areas of the body. In addition, it is important to buy from reputable manufacturers, as some products have been found to contain much less bacteria than was stated on the label.9
