Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Lactobacillus delbrueckii subsp. lactis is a lactic acid bacterium commonly used as a starter culture in the production of fermented dairy products, such as yogurt and cheese. Its relevance to lactose intolerance primarily relates to its ability to ferment lactose into lactic acid, effectively reducing the lactose content of dairy products. Several studies have shown that the consumption of fermented dairy products containing live cultures of Lactobacillus delbrueckii (typically in combination with Streptococcus thermophilus) can improve lactose digestion and tolerance in lactose-intolerant individuals. This benefit is partly due to the bacterial production of β-galactosidase (lactase), which helps break down lactose in the gut.

However, direct studies focusing solely on L. delbrueckii subsp. lactis (as opposed to the closely related L. delbrueckii subsp. bulgaricus or mixed cultures) are limited. Most of the clinical evidence supporting the use of live yogurt cultures for lactose intolerance is based on the combined effect of multiple bacteria. The FDA allows the claim that yogurt containing live and active cultures can improve lactose digestion, but this is not specific to L. delbrueckii lactis alone. Thus, while there is some scientific rationale and indirect evidence, the strength of direct evidence specifically for L. delbrueckii lactis is moderate at best.
