Postbiotic Lactobacillus plantarum L-137™
60 capsules
Item Catalog Number: K2707EN
Original product name: Postbiotic Lactobacillus plantarum L-137™
Lactobacillus plantarum L-137™, by activating immune cells, supports the production of hyaluronic acid, which is responsible for maintaining optimal skin hydration.[4,14]
A group of scientists conducted a study to assess the impact of Lactobacillus plantarum L-137 on the condition of dry skin and its hydration status. The 12-week study involved 80 people with dry skin who were divided into two groups - placebo and Lactobacillus plantarum L-137. In the Lactobacillus plantarum L-137 group, a decrease in transepidermal water loss from the face and an increase in water content in the skin of the forearm were observed. The greatest improvement was noted in participants who had the driest skin.
Supplementation with Lactobacillus plantarum L-137 may therefore be an effective complement to therapy for dry and dehydrated skin.[1,7]
Lactobacillus plantarum L-137 supports the production of hyaluronic acid, retains water in the skin, and supports optimal skin hydration.[4,14] Therefore, we can safely say that it supports a younger appearance.
Benefits at a Glance:
Lactobacillus plantarum L-137, a strain inactivated by high temperature, may support the defense capabilities of the immune system.
Numerous studies have demonstrated the effectiveness of Lactobacillus plantarum L-137 as an immune stimulator in people with weakened immune functions who are more susceptible to infections. Lactobacillus plantarum L-137 also improves immune functions in people with an overactive immune system (allergy sufferers and people suffering from autoimmune diseases). Of the above-mentioned reasons, Lactobacillus plantarum L-137 is often called an immunobiotic.[8]
Lactobacillus plantarum L-137 has a synergistic effect with Vitamin C, E, and beta-glucan. Interleukin-12 production in mouse immune cells stimulated by Lactobacillus plantarum L-137 is visibly enhanced by vitamin C, vitamin E, and beta-glucan.[3]
A study conducted in a rat model of metabolic syndrome showed that oral supplementation with Lactobacillus plantarum L-137 had an anti-inflammatory effect on the heart and adipose tissue. The symptoms of heart failure and the amount of fat accumulated under the skin were reduced. A reduction in insulin resistance and a reduction in the level of pro-inflammatory interleukin-6 were also noted.[10]
Lactobacillus plantarum L-137 stimulates immune-boosting cells to start a healing process in the mouth.[12]
The 12-week placebo-controlled, randomized, double-blind clinical trial involved 39 people with chronic periodontitis. Half of the study participants received a placebo and the other half received a capsule containing Lactobacillus plantarum L-137.[9-11,12]
At the beginning of the study, the depth of the dental pocket was measured in all participants (in healthy people, it is 3 mm or less). At the end of the study, in the Lactobacillus plantarum L-137 group, participants with an initial pocket depth of 4 mm or more had a 64% improvement (the depth of the dental pocket decreased) compared to the placebo group.[9-11,12]
The results of this study demonstrate that periodontal disease can be alleviated with oral supplementation of Lactobacillus plantarum L-137.

L-137™ is a heat-killed (non-viable) form of Lactobacillus plantarum strain L-137, making it a postbiotic rather than traditional probiotic. Unlike live probiotics that must survive stomach acid to colonize the gut, postbiotics consist of beneficial bacterial components that remain stable and effective without requiring refrigeration or special handling. Heat treatment actually enhances L-137's immune-stimulating properties by exposing cell wall components that activate immune receptors. This postbiotic approach offers advantages: stable shelf life, no refrigeration needed, safe for immunocompromised individuals, and targeted immune modulation without altering gut microbiome composition. L-137™ specifically activates innate immunity through TLR2 receptors, supporting robust immune responses. For convenient, research-backed immune support, postbiotics like L-137™ represent next-generation probiotic science.
L-137™ provides powerful immune support through activation of innate immunity—the body's first-line defense system. The heat-killed bacteria's cell wall components interact with TLR2 (Toll-like receptor 2) on immune cells, triggering enhanced immune surveillance and responsiveness. This activation increases natural killer cell activity, supports interferon production, and promotes balanced cytokine responses. Clinical studies show L-137™ reduces duration and severity of seasonal immune challenges. It supports healthy immune responses without overstimulation or immune exhaustion. The postbiotic also enhances antibody production supporting adaptive immunity. Unlike immune stimulants that may cause inflammation, L-137™ modulates immunity promoting appropriate responses when needed. For year-round immune resilience, seasonal support, or enhanced recovery, L-137™ offers clinically validated immune enhancement.
Yes, L-137™ excels at supporting immune wellness during seasonal challenges. Clinical trials demonstrate supplementation before and during challenging seasons significantly reduces incidence and severity of seasonal immune concerns. The postbiotic primes immune system readiness, allowing faster, more effective responses when challenges arise. Studies show L-137™ reduces symptom duration, supports quicker recovery, and maintains daily function during seasonal periods. It's particularly effective when started proactively 2-4 weeks before expected seasonal challenges, though benefits appear even when started acutely. The immune training effect of L-137™ helps the body mount appropriate defenses without excessive inflammation that can worsen symptoms. For families, schools, healthcare workers, or anyone seeking seasonal immune protection, L-137™ provides research-backed preventive and responsive immune support.
Yes, L-137™ is exceptionally safe, even for populations where live probiotics may be contraindicated. Since the bacteria are heat-killed, there's no risk of bacterial translocation or infection—concerns for immunocompromised individuals, people with central lines, or those on immunosuppressants. The postbiotic doesn't colonize the gut or compete with existing microbiome, making it safe for those with dysbiosis or sensitive digestive systems. No refrigeration requirement means stable potency and convenience. L-137™ has been extensively safety tested in clinical trials including vulnerable populations, demonstrating excellent tolerability with minimal side effects. It can be safely combined with antibiotics, medications, and other supplements. For people seeking immune support but unable or unwilling to use live probiotics, L-137™ offers effective, safe alternative delivering immune benefits without live bacteria concerns.
For immune support, take L-137™ daily as directed on the label, typically 10-50 mg per day depending on formulation and immune goals. The postbiotic can be taken with or without food at any time of day. For seasonal immune preparation, start supplementation 2-4 weeks before challenging seasons and continue throughout. For year-round immune resilience, consistent daily use provides ongoing benefits. During acute immune challenges, L-137™ can be taken for responsive support though preventive use is more effective. Effects are cumulative—immune training effects strengthen with continued supplementation. L-137™ is safe for long-term use. No special storage needed unlike live probiotics. Can be combined with other immune nutrients like vitamin D, zinc, and elderberry for comprehensive support. For optimal immune wellness, pair L-137™ with healthy sleep, stress management, and balanced nutrition.
