Weight Gain and Safety of Lactobacillus reuteri DSM 17938 Supplementation
In this conversation, the user asks about expected weight gain from Lactobacillus reuteri DSM 17938 and its general safety. The assistant explains that no robust evidence links this probiotic strain to weight gain, it is generally safe for most people, but cautions for immunocompromised individuals.
How much weight gain can I expect from taking Lactobacillus reuteri DSM 17938 as a supplement, and is it safe for general use?
Based on the available information, there is no robust clinical evidence in Pillser's research database or from other authoritative sources specifically linking Lactobacillus reuteri DSM 17938 supplementation to weight gain in humans.
Weight Gain Effects
- Lactobacillus reuteri DSM 17938 is generally studied for gastrointestinal health (e.g., infant colic, H. pylori management, antibiotic-associated diarrhea), not for weight gain. There is no established evidence to suggest a specific amount of weight gain (or loss) that can be expected from this probiotic strain.
- Some probiotic strains may influence body weight by modulating gut microbiota, but any such effect tends to be small, strain-specific, and inconsistent. The DSM 17938 strain, in particular, has not been shown in the literature to meaningfully affect body weight in either direction.
Safety Profile
- Generally recognized as safe for the general population, including infants and children. It is one of the most well-studied probiotic strains and is widely available.
- Common side effects are typically mild and may include transient gas, bloating, or digestive discomfort in the first few days of use.
- Caution is advised for individuals who are immunocompromised, have short bowel syndrome, have central venous catheters, or are critically ill — in these populations, there is a theoretical risk of probiotic-related sepsis, though it is extremely rare.
Bottom Line
Do not expect any significant weight gain from Lactobacillus reuteri DSM 17938. It is a safe probiotic for the vast majority of people when used as directed. As always, it's advisable to consult with a healthcare professional before starting any new supplement regimen, especially if you have underlying health conditions.
