What we love about LL-37:
LL-37 peptide is anti-viral, anti-fungal, and anti-bacterial that leading functional medicine clinics will use for major detox protocols such as Lyme, mold, and more. This one is often paired with Thymosin Alpha 1 for the most powerful 1+1 combo to boost immunity and detoxification. We have seen it prescribed by world-leading physicians for these conditions.
LL-37 is an antimicrobial peptide, and antimicrobial peptides (AMPs) are widely recognized as a viable alternative to antibiotics. Essentially, AMPs destroy microbial infections. These peptides have the ability to regulate the invasion of bacteria and viruses, hence preventing infections.
According to research, AMPs may stimulate the innate mucosal immune response, hence aiding in infection eradication. The term “mucosal” refers to the immune response that occurs on mucosal membranes, such as those in the intestines, urogenital tract, and respiratory system—surfaces that are immediately exposed to the outside world.
What’s LL-33
LL-37 is regarded as an important tool for combating many dangerous pathogens in the body. It is produced by numerous cell types, such as natural killer (NK) cells, white blood cells, and skin cells. Furthermore, other physiological systems, including the respiratory system, gastrointestinal tract, testes, and ocular surface, contribute to the creation of LL-37.
This powerful peptide has piqued the interest of the research community due to its immune-modulating properties. Researchers are attracted by its potential to accelerate tissue repair and considerably increase the survival rates of people suffering from chronic and debilitating medical conditions.
How LL-37 Works
LL-37 belongs to the cathelicidin family of antimicrobial peptides. When neutrophils, a type of white blood cell, get activated, they release this peptide in its mature form. LL-37 is expressed in a variety of cells and organs, including circulating neutrophils, bone marrow cells, skin epithelial cells, gastrointestinal tract cells, the epididymis, and the lungs.
The production of LL-37 in macrophages is triggered by vitamin D, which is generated by sunlight exposure to the skin. LL-37 plays a crucial role in the initial defense against infection and the systemic invasion of pathogens, particularly at sites of inflammation and wounds. It exhibits toxicity against both bacterial and normal cells and possesses significant resistance to proteolytic degradation.
Benefits of LL-37
LL-37 is an adaptable host defense peptide that serves several functions. In addition to its antibacterial and antibiofilm properties, it elicits a variety of responses in various cells, either directly or via altering cellular reactions to microbial chemicals and immunological mediators. These membrane-disrupting antimicrobial peptides play an important role in providing broad-spectrum protection against localized bacterial infections. Here additional benefits of LL-37:
Tissue Healing
Beyond its anti-biofilm and antimicrobial properties, LL-37 plays a crucial role in maintaining the delicate balance between pro- and anti-inflammatory molecules. This equilibrium is essential as inflammatory responses are vital for the body’s defense against invading pathogens. However, if left unchecked, these same responses can hinder proper healing, encourage the formation of scar tissue, and even contribute to autoimmune diseases.
LL-37 appears to contribute significantly to balancing inflammation with healing, with its effects mediated through interactions with macrophages. Macrophages, upon detecting foreign pathogens, initiate inflammatory responses by signaling the need for defense throughout the body. The presence of LL-37 transforms anti-inflammatory macrophages into their pro-inflammatory counterparts, influencing the dynamic interplay between inflammation and healing.
Wound Healing
LL-37 exhibits a promising capability to inhibit the formation of biofilms, making it a valuable asset in the treatment of chronically infected wounds caused by S. aureus and P. aeruginosa. Its anti-biofilm properties play a crucial role in revealing and eliminating the underlying bacteria. Additionally, the interaction of the peptide with keratinocytes and fibroblasts promotes the closure of wounds, further enhancing its potential for therapeutic applications in wound healing.
Cancer Treatment
Studies show that LL-37 is effective in treating various types of cancer cells. Notably, LL-37 inhibits the growth of gastric cancer cells by increasing bone morphogenetic protein (BMP) signaling. However, it is vital to note that LL-37 overexpression has been linked to the development and progression of ovarian, lung, and breast malignancies.
Side Effects of LL-37
Side effects linked to LL-37 are extremely rare. Some reported issues in patients using this drug include increased inflammation, induction of autoimmune disease, depression, and damage to sperm surface membranes. It’s important to note that these side effects were observed in some cases but were not definitively confirmed to be directly associated with LL-37 treatment. There is a possibility that these occurrences were coincidental and not necessarily related to the use of LL-37. Despite the rarity of these associated side effects, they are listed to acknowledge the observed instances and exercise caution in the use of LL-37.
LL-37 Dosage and Cycling
The appropriate dosage of LL-37 can vary depending on the specific purpose for which it is being used, and it is essential to seek advice from a healthcare professional. As a general guideline, initiating with 100 mcg per day is commonly suggested. LL-37 can be safely administered daily for a maximum duration of 3 months. To observe optimal benefits, it is recommended to continue the peptide cycle for at least one month.
Dosing may be gradually increased after the introduction of the peptide into the body. Following one cycle, a break of approximately 2-4 weeks is advisable before starting another cycle. This break allows the body to restore equilibrium and prepare for the next phase of the peptide regimen.
Stacking LL-37
To achieve faster and more pronounced benefits, some users practice stacking LL-37. This peptide is commonly stacked with TB-500, a regenerative peptide known for its ability to enhance tissue healing and exert anti-inflammatory properties. Additionally, LL-37 can be combined with vitamin D, as it is believed to offer synergistic benefits that enhance the effectiveness of LL-37.
Conclusion
LL-37, an antimicrobial peptide, is a promising antibiotic alternative that fights infections. It stimulates the body’s defense on surfaces like the intestines. Made by various cells, LL-37 helps tissue repair and survival in chronic conditions. It defends against infections and balances inflammation. LL-37 also aids wound healing and shows promise against certain cancers.
