A new review published in the journal Hypertension evaluated results of multiple trials concluding that daily consumption of probiotics can reduced blood pressure levels by 2 to 3 mm Hg. Even though this is not a significant reduction, probiotics in general have multiple benefits. What are your favorite sources of probiotics?

Taking daily doses of probiotics can help reduce episodes of diarrhea and respiratory tract infections in children at day care centers. This randomized, double-blinded trial published in Pediatrics evaluated 336 healthy children, aged 6 months to 3 years old, whom half received Lactobacillus reuteri (probiotic) and half received an identical placebo. During the 3 month study, there were 69 cases of diarrhea in the placebo group versus 42 cases in the supplement group. The placebo group also had 204 cases of respiratory tract infections with subjects spending an average of 4.1 days on antibiotics, while the L. reuteri group had 93 cases of respiratory tract infections and subjects spent an average of 2.7 days on antibiotics. Follow-up continued for 3 months after the trial without any supplements of probiotics. There seems to be a beneficial effect for children taking daily doses of L. reuteri to have a significant reduction in episodes of diarrhea as well as respiratory tract infections. What are your thoughts on giving infants and children probiotics to prevent possible illnesses?

Probiotics are mainly known to benefit the digestive tract, but may also have a potential new advantage- cholesterol lowering. A 9-week, randomized trial conducted at McGill University evaluated 127 patients with high cholesterol. Half of these patients received a probiotic supplement twice a day and the other half took a placebo. Total cholesterol levels of those who took the probiotic dropped by 9% and their LDL cholesterol levels by 12%. However, one must keep in mind that this study was financed by a company that produces probiotics. What conditions do you routinely take/recommend probiotics for?

A meta-analysis published in the Annals of Internal Medicine, reports that probiotics may prevent Clostridium difficile–associated diarrhea (CDAD) in patients taking antibiotics. Data was pooled from 20 randomized controlled clinical trials evaluating probiotics compared to placebo or no treatment and the occurrence of CDAD. The results indicated that the occurrence of CDAD was decreased by 66% in those taking probiotics. What questions have you received from patients about the use of probiotics? What other indications do you recommend probiotics for?
