Can Probiotics Help Lactose Intolerance Patients?

Lactose intolerance is a common condition affecting around 68% of the world's population; its prevalence varies among different countries.1 Lactose intolerance is not an allergy; it is just the decreased ability to digest lactose. Lactose is a type of sugar that is naturally found in the milk of most mammals. It consists of glucose and galactose. In a person with normal lactose digestion, the lactase enzyme, located in our small intestine, breaks lactose down into glucose and galactose so that the body can process it further. However, those considered to have lactose intolerance have an absence or drastically reduced levels of intestinal lactase, which causes larger amounts of undigested lactose to enter the large intestine, where it is fermented by the intestinal bacteria. This leads to symptoms such as bloating, flatulence, nausea, vomiting, diarrhea, gut distension, abdominal pain, and headaches.

A very common approach to managing lactose intolerance symptoms is to avoid milk and dairy products. Although this can lead to calcium, phosphorus, vitamin D, and riboflavin (vitamin B2) deficiency, underpinning diseases such as osteoporosis and a decreased quality of life, which can lead to depression. Another very common approach is to ingest an exogenous lactase enzyme (β-galactosidase) prior to milk and dairy product consumption. However, the intake of lactose, sometimes, can be higher than what the exogenous enzyme is capable of digesting, leading to the appearance of uncomfortable symptoms; it may have a different taste; and it can be expensive over time.

A novel approach consists of using probiotics — live microorganisms that confer a health benefit on the host when administered in adequate amounts. Several studies have shown that probiotics can improve gut barrier function and host immune response. Probiotic microorganisms can produce antimicrobial molecules, thus counteracting infections caused by infectious agents. Probiotics can also produce vitamins, such as riboflavin, and food-degrading enzymes, such as lactase (i.e. -galactosidase), that can be helpful during digestion.

A recently published meta-analyses carried out by Oliveira et al., showed that L. reuteri DSM 17938 and L. acidophilus DDS-1 supplementation can lead to a decrease in the lactose intolerance symptoms.2 Another study showed that B. bifidum 900791, can also ameliorate lactose intolerance symptoms.3

Thus, administration of β-galactosidase-producing probiotics may be beneficial in people suffering from lactose intolerance to alleviate symptoms caused by lactose malabsorption. However, it is noteworthy that the effect may strongly depend on specific strains and concentrations to be effective.
