Lactococcus lactis subsp. lactis R1058
Also known as: L. lactis R1058, Lactococcus lactis R1058, probiotic strain R1058
Effective Dosage
No established dose
What the Science Says
Lactococcus lactis subsp. lactis R1058 is a specific strain of lactic acid bacteria commonly used in probiotic supplements. Like other Lactococcus lactis strains, it is generally considered safe and has a long history of use in fermented foods. It may support gut microbiome balance, but no published clinical trials specific to this strain were available to confirm any health benefits or effective dosing.
What It Doesn't Do
No clinical evidence it treats digestive disorders. No proven immune-boosting effect for this specific strain. Don't assume benefits from other probiotic strains apply here — strain specificity matters. Not a substitute for medical treatment of gut conditions.

Absorption & Bioavailability
Unknown — no study data available for this specific strain. General probiotic survival through the GI tract varies widely by formulation and delivery method.
Red Flags to Watch For
- Despite appearing in 882+ registered supplement products, only 1 clinical trial is indexed on PubMed — this is a major research gap for such a widely sold ingredient.
- Strain-specific benefits cannot be assumed from general probiotic research — always look for studies on the exact strain.
- No established effective dose exists, making it impossible to evaluate whether products contain a meaningful amount.
- Heavy commercial use with minimal published evidence is a common pattern in the probiotic industry — be skeptical of strong health claims.
