What the Science Says
Lactobacillus plantarum LP-115 is a strain of beneficial bacteria used in probiotic supplements. The limited available research suggests it is generally safe and well-tolerated in healthy adults when taken short-term, and it can survive passage through the gastrointestinal tract. However, it has not been shown to outperform other probiotic strains for any specific health outcome in human clinical trials.
What It Doesn't Do
Not proven to treat or prevent inflammatory bowel disease — animal research actually showed it had no effect on colitis. No human clinical trials back claims about immune support, digestive relief, or any specific health benefit unique to this strain. Don't assume it works just because other Lactobacillus strains do.
Evidence-Based Benefits
Appears safe and well-tolerated in healthy adults over short-term use.

Absorption & Bioavailability
Moderate — research confirms the strain can survive simulated gastric passage and persist in the gut, but recovery rates vary by dose and formulation.
Red Flags to Watch For
- Zero human clinical trials exist for this specific strain — all efficacy data comes from animal or in vitro studies
- Animal research showed LP-115 had NO effect on colitis, unlike some other probiotic strains tested alongside it
- Most human safety data comes from a tiny 10-person open-label study using a multi-strain product, not LP-115 alone
- Widely used in over 1,000 registered supplement products despite a near-total absence of strain-specific clinical evidence
