Can Lactobacillus Acidophilus probiotic help Lactose Intolerance?

Can Lactobacillus Acidophilus probiotic help Lactose Intolerance? By Nutritionist Kay Ali

Lactose Intolerance is when you cannot efficiently digest lactose, a sugar found in milk and dairy products. Symptoms include abdominal discomfort, excessive gas, flatulence and diarrhea just a few hours after lactose consumption. The cause is due to insufficient production of lactase, the enzyme that helps you breakdown lactose. Treatment by conventional medicine is to avoid all foods containing lactose, which can make dining out or socialising with friends super challenging. The good news is there is some research that suggests daily consumption of Lactobacillus Acidophilus DDS1 might help.



A randomized, double-blind, placebo-controlled, crossover study evaluated the

effect of Lactobacillus Acidophilus DDS1, taken once daily for 4 weeks, on relieving

discomfort related to lactose intolerance.[1] The study enrolled healthy volunteers

between 18 and 75 years of age who screened positive to lactose intolerance. Results showed that Lactobacillus Acidophilus DDS1 was statistically significant compared to placebo in reducing diarrhea, abdominal cramping and vomiting at week 4 of probiotic consumption. These results indicate that incorporating probiotic supplements with Lactobacillus Acidophilus DDS1, may offer a complementary care in individuals diagnosed with lactose intolerance.
