Miracle cure for canine papilloma virus. Our 6-month-old boxer puppy had been suffering from canine papilloma virus for almost 3 months. She had large warts on her face, including some inside her mouth, making it difficult for her to eat. They bled constantly, making her miserable. After reading about L-Lysine online as a remedy, I purchased these. Within 2 days the warts began to shrink noticeably, and they were entirely gone within a week.

L-Lysine is my top supplement for any viral infection. It aids in faster recovery and prevents lingering colds. My daughters were set to have their adenoids removed due to the presence of EBV, but after taking L-lysine along with prescribed medications, EBV was no longer detected. I genuinely believe L-lysine played a vital role in our recovery.

We explored how L-lysine, specifically the iNOS inhibitor N-iminoethyl-L-lysine (L-NIL), affects the progression of atherosclerosis in rabbits with high cholesterol. In our controlled study, we compared rabbits treated with L-NIL, a vehicle, or L-arginine after being fed a cholesterol-rich diet.

The results were promising; L-NIL limited the progression of atherosclerosis in the rabbits. We observed notable differences in arterial health, with less disease advancement in the L-NIL group compared to the control groups. L-arginine showed some benefits, but not to the same extent as L-NIL.

Herpes appeared, but I recovered relatively easily. I purchased 500mg lysine as I frequently get cold sores. I took it once or twice a day, and after tiring myself, I had a terrible outbreak. I think I wasn't taking enough; I read that one needs about 30 mg per kg of body weight, which means 1500 to 2000 mg a day. After starting high doses of 1500-2000mg at the first signs of herpes, I noticed minimal tingling and swelling. I believe lysine is a strong ally for swollen lymph nodes and herpes!

We looked into how ketoprofen lysine salt (KLS) mouthwash stacks up against benzydamine hydrochloride (BH) for treating sore throats. In a single-blind study with 241 patients, both mouthwashes were used twice daily for seven days. Results showed that KLS provided longer-lasting pain relief and was better tolerated than BH. While both treatments had some side effects, significantly more BH users reported issues. Overall, it seems KLS might be the more effective option for soothing a sore throat.

A superb remedy, this lysine is far more effective than Solaray—I have experienced it myself. It's ideal for a regimen against the Epstein Barr virus, but it works best when combined with monolaurin and colostrum, and requires a long-term intake of at least three months. By the end of my second month, both my chronic tonsillitis and laryngitis vanished, and my thyroid gland is gradually recovering! Please note that on days five to ten, you may experience severe intoxication; do not discontinue use—taking a sorbent will help!

I've been using all these supplements for two months, and while I have not experienced side effects, my iron levels have returned to normal. Healing takes time, but I see a positive trend, and while I don’t believe lysine alone is responsible, it certainly helps.

We examined the effectiveness of long-term lysine supplementation for preventing cold sores, specifically in individuals with a history of frequent outbreaks. Over a 12-month period, twenty-six volunteers participated in a double-blind study, taking daily doses of 1,000 mg of lysine.

Our findings indicated that those taking lysine experienced significantly fewer lesions compared to the control group. Moreover, when participants stopped the supplementation, their outbreaks increased. Maintaining serum lysine levels above 165 nmol/ml appeared crucial for effectiveness, highlighting lysine's potential benefits in managing recurrent cold sores.

Excellent result! I read that children with autism have a herpes viral load. I began giving it to my daughter. The girls initially erupted, but it was clearly not an allergic reaction; rather, they were herpes lesions. As soon as the spots started to go, her mind and eyes became much clearer. Now, whenever I notice her autistic traits returning, I give her a capsule or two. The spots reappear, yet her autistic traits nearly vanish, accompanied by the acne. This herpes treatment—by utilising its building material—takes arginine, similar to lysine, and begins to break down. It removes the brain tumour and leaves. A miraculous solution. I will order regularly.

We examined how Zhigancao Decoction (ZGCD) affects diabetic cardiomyopathy (DCM), aiming to uncover its clinical benefits and underlying mechanisms. After analyzing numerous studies, we found that ZGCD significantly improves cardiac function and reduces blood pressure more effectively than conventional treatments. Additionally, it appears to have fewer side effects. The positive effects are likely linked to its ability to influence the AGEs-RAGE signaling pathway, boost lipid metabolism, and reduce atherosclerosis. However, it's important to note that more research is needed to fully understand these mechanisms.

We explored the effects of G2 lysine dendrimer on acne and how it can help restore balance to our skin microbiome. Acne is a persistent skin condition that brings about discomfort and concerns for many. Traditional treatments can often lose their effectiveness over time or lead to unwanted side effects. So, our goal was to see if this new approach could offer a gentler solution.

Our focus was on how G2 dendrimer specifically targets the troublesome bacteria associated with acne while preserving the healthy bacteria we rely on for healthy skin. Through our studies, we found that G2 dendrimer notably reduced inflammatory markers linked to acne, such as IL-8. What’s more, it didn’t harm the beneficial bacteria on the skin, which is essential for maintaining overall skin health.

We also conducted comparisons with standard over-the-counter treatments. The G2 dendrimer showed promising results in both limiting acne outbreaks and supporting the survival of good bacteria. Through metagenomic analysis, we confirmed that using G2 in a cosmetic product can effectively help rebalance the acne-prone microbiota without disrupting the friendly bacteria.

Overall, these findings highlight the potential of G2 lysine dendrimer as a non-aggressive option for acne prevention while respecting our skin's natural microbiome.

We set out to uncover how certain amino acids, particularly lysine, help with cold acclimation. Over three months, 20 men were monitored for physiological changes after being exposed to cold.

We found that continuous exposure led to faster cold-induced vasodilation and improved finger temperature. Notably, lysine was the only amino acid that significantly changed and positively correlated with these improvements in cold response.

In mouse trials, lysine supplementation helped maintain core body temperature during cold exposure, indicating its role in supporting metabolic adjustments to the cold.

We delved into the connection between nutritional factors and hair loss, especially focusing on l-lysine. The study revealed that while a variety of nutrients influence hair health, l-lysine stood out as potentially beneficial. A double-blind study showed that many women experiencing increased hair shedding responded positively to treatments combining l-lysine with iron.

However, the research also highlighted that there is no strong evidence linking low zinc levels to hair loss. Overconsumption of supplements could even worsen hair loss if no deficiency is present. Overall, while nutrition plays a role, proper hair care and understanding the hair cycle are equally significant.

We investigated how L-lysine, an essential amino acid, influences anxiety and body weight. The study involved administering two doses of L-lys to rats over 20 days.

We found that while L-lys didn't affect food intake, it did lead to weight reduction and showed signs of anxiolytic effects on the first day. Notably, repeated doses increased serotonin levels in key brain areas, which may explain its calming effects.

However, the study's outcomes indicate that L-lys may not dramatically alter anxiety compared to other treatments.

L-lysine aids in synthesising antibodies, hormones, and enzymes while lowering triglycerides. It has antiviral effects, particularly against herpes and respiratory infections. Personally, I have noticed reduced anxiety levels and successfully tackled the herpes virus with lysine.

We explored the impact of L-lysine on back pain in 220 patients suffering from dorsalgia. By using multiple pain assessment tools, we aimed to understand how effective L-lysine aescinat could be in reducing pain and improving movement.

The results were promising; L-lysine aescinat significantly hastened the recovery from pain and helped restore movement functions. It showed great potential in addressing radicular syndrome as well. This suggests that L-lysine might be a valuable addition to treatment plans for back pain.

Lysine bolsters fat metabolism and energy production, while also supporting the immune system. After six months of combining it with L-carnitine, I’ve experienced a surge in energy, improved mood, and less stress. I feel more vigorous and resistant to illness, as if I’ve fortified my health against outside challenges.

We explored how dietary changes and supplements impact skin conditions like herpes labialis. Specifically, we found that L-lysine can be effective as a preventive measure against herpes outbreaks. However, it doesn’t help shorten the duration of active lesions once they appear. Despite popular beliefs around diet's role in such conditions, we observed that high-quality evidence supporting dietary changes for other skin issues like rosacea is lacking. Additionally, certain vitamins and minerals showed promise in treating conditions like hidradenitis suppurativa.

Lysine is essential for treating herpes and is always part of my regimen. I start with a loading dose before reducing it, and I combine it with vitamin C, zinc, and vitamin D. It works because lysine inhibits the herpes virus, which thrives on arginine.

We explored the connection between NSD2 and bone health, specifically how it affects bone marrow stem cells in osteoporosis. By using advanced techniques, we found that NSD2 inhibits the growth of these cells, which is crucial for healthy bones.

In animal models of osteoporosis, blocking NSD2 not only promoted stem cell differentiation but also helped prevent bone loss. Our findings suggest that targeting NSD2 could be a new way to treat osteoporosis and improve bone health.

We investigated how RCI001 can help mice with primary Sjögren syndrome. Eight 12-week-old NOD.B10-H2b mice were divided into two groups, one receiving RCI001 and the other a control treatment.

After one week, we noted significant improvements in eye health and tear secretion for the RCI group. They also showed reduced levels of inflammatory markers compared to those treated with the control. Overall, RCI001 proved to effectively reduce inflammation and oxidative stress, suggesting a promising therapeutic option for this autoimmune disease.

I’ve started giving L-lysine to my daughter, noticing improvements with her autism-related symptoms. While some herpes lesions initially appeared, as they cleared, her cognitive function seemed to improve. It appears that lysine plays an essential role here.

We examined the effects of an arginine-lysine-lactose combination on bone pain in older adults with osteoporosis. In our study of 40 participants, we compared those receiving this treatment to a control group receiving carbocalcitonin alone.

After six months, we observed that the group treated with arginine-lysine-lactose showed greater improvements, including increased bone density and reduced pain. These benefits likely stem from enhanced calcium absorption linked to lysine and lactose.

Overall, the combination proved effective in alleviating bone pain symptoms associated with aging.

Great supplement! This was recommended by my doctor. After Covid, my immunity plummeted and many medications didn’t help. I had Epstein Barr in my blood, experienced bone pain, and suffered from a constant temperature for several months. After taking the supplement (30 minutes before meals in the morning), the pain disappeared, and my temperature returned to normal. Now, whenever I suspect illness, I use this supplement along with vitamin C and D3, and everything is absolutely fine.
