The Effect of Probiotics on Lactose Intolerance (LI)

Highest rates of LI are found in the Asian populations. The diagnosis of LI based on patients' symptoms is sometimes problematic, since these symptoms are not specific and may differ from one patient to another. Two possible interventions in the case of LI are the supplement of commercially available lactase (tablets) or the addition of probiotics.

Probiotics are live microorganisms that are commonly used in order to prevent or treat a disease. The current definition by the Food and Drug Administration and the World Health Organization is "Live microorganisms which, when administered in adequate amounts, confer a health benefit on the host."

These microorganisms are a heterogeneous group, they are nonpathogenic and produce beta- galactosidase or lactase intracellularly that may assist in the digestion of lactose. Studies have shown that people with lactose intolerance tolerated the lactose in yogurt better than the same amount of lactose in milk.

The assumption was that the presence of lactase producing bacteria in the yogurt, especially Lactobacillus acidophilus, contributed to the digestion and absorption of lactose. It was also found that the presence of Streptococcus thermophilus alleviate lactose intolerance through their ability to produce lactase enzyme.

Lactokids + is safe for children with LI and have both active Lactobacillus acidophilus and Streptococcus thermophilus strains which can help improve LI condition. Lactomin is also safe for adults with LI and has active Lactobacillus acidophilus strain which can help with LI condition. As symptoms of LI are not specific and differ from one individual to another. LI conditions can range from mild to severe cases. It is still recommended and best to seek your medical professional for medical advice on unique cases.
