G2 dendrimer supports acne solutions
Lysine-Dendrimer, a New Non-Aggressive Solution to Rebalance the Microbiota of Acne-Prone Skin.
Most Relevant Research
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.

Improved skin condition
Most Useful Review
Rejuvenates! I take it alongside L-proline from the same company, and my skin condition has genuinely improved. I need to take it continuously but have breaks for two months. I also supplement this with niacin (vitamin B3), vitamin D3, and omega-3. Additionally, I take artichoke on an empty stomach for liver support, and inositol can also be beneficial. My skin feels and looks as if I've been to a beautician: nourished, elastic, smooth, with no rashes, just velvety skin! If you find my insights valuable for personal use, please click yes.

RCI001 shows promise for Sjögren syndrome
Efficacy of RCI001 as a Therapeutic Candidate in a Primary Sjögren Syndrome Mouse Model.
Most Relevant Research
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.

Lysine aids cold adaptation mechanisms
Cold exposure accelerates lysine catabolism to promote cold acclimation via remodeling hepatic histone crotonylation.
Most Relevant Research
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.

This product speeds up the healing time for cold sores. My girlfriend, who has struggled with them her entire life, recently had one forming. After taking a tablet daily, her sore is in its last stages and did not fully develop. She highly recommends it to anyone who feels a cold sore coming on.

Anxiety reduction observed with lysine
Anxiolytic, anti-nociceptive and body weight reducing effects of L-lysine in rats: Relationship with brain serotonin an In-Vivo and In-Silico study.
Most Relevant Research
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.

Lysine helps reduce cold sore outbreaks
Lysine as a prophylactic agent in the treatment of recurrent herpes simplex labialis.
Most Relevant Research
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.

Lysine improves herpes symptoms
Subjective response to lysine in the therapy of herpes simplex.
Most Relevant Research
We explored the effectiveness of lysine supplementation in treating herpes infections through a survey of 1,543 participants after a six-month trial. The findings revealed that a substantial 84% reported that lysine helped prevent recurrences or reduced the frequency of outbreaks.

Notably, only 8% of users described their symptoms as severe while taking lysine, compared to 79% who felt that way without it. Healing times improved significantly; 83% felt lesions healed in five days or less with lysine, while 90% said healing took longer without it. Overall, 88% regarded lysine as an effective treatment.

I experienced shingles seven times in four years. A new holistic dentist advised me to take L-lysine. After following his guidance of 1000 mg daily and up to 3000 mg during stress or illness, I have not had further shingles episodes, and my health has improved significantly. I highly endorse this product based on my experience.

Breakout-free success
Most Useful Review
No more herpes breakouts! I'm amazed at this supplement! I've re-ordered multiple times and don’t want to be without it. I previously had prescribed medication for outbreaks but disliked long-term use. I started taking Lysine after seeing it could help herpes breakouts. Initially one tablet didn’t suffice, but I increased to two daily—it worked! I've been breakout-free for months now and would highly recommend it!

Effectiveness of lysine on bone pain
[The effects of the carbocalcitonin + arginine-lysine-lactose combination in senile involutional osteoporosis].
Most Relevant Research
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.

NSD2 inhibition may reduce osteoporosis
NSD2-mediated H3K36me2 exacerbates osteoporosis via activation of hoxa2 in bone marrow mesenchymal stem cells.
Most Relevant Research
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.

Flu prevention boost
Most Useful Review
A brilliant immune booster! I have used L Lysine for many years and favour this brand, although I wish it came in easier-to-swallow capsules. I take it as a preventative measure against flu. Whenever exposed to someone with a contagious illness, I start taking L-Lysine immediately, at 4000mg three or four times a day. I do the same if I sense a cold or sore throat. Prompt action is key, as waiting can reduce its effectiveness. Lysine is also helpful while travelling on planes, a great defence against sickness.
