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.

Lysine aids cold adaptation
Cold exposure accelerates lysine catabolism to promote cold acclimation via remodeling hepatic histone crotonylation.
Most Relevant Research
We focused on understanding how lysine, an essential amino acid, plays a role in cold acclimation. Our study involved twenty male participants who underwent three months of natural cold exposure, during which we measured cold-induced vasodilation (CIVD) and analyzed plasma amino acid levels.

After the three-month cold exposure, we observed that continuous exposure led to quicker CIVD responses and better finger temperature regulation. Notably, we found decreases in plasma levels of lysine and glycine in both humans and mice. Lysine emerged as the key amino acid showing significant changes that correlated strongly with improved CIVD outcomes.

To delve deeper, we conducted an experiment where mice were given lysine supplements during a week of cold exposure. These mice maintained higher core and surface temperatures, indicating a protective effect against cold. Additionally, lysine supplementation seemed to promote certain liver functions by increasing levels of specific histones and gene expressions related to metabolism.

Overall, our findings highlight lysine not only as a critical player in adapting to cold conditions but also suggest its potential importance for metabolic health during such challenges.

L-lysine shows anxiety-reducing effects
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 explored how L-lysine, an essential amino acid, impacts anxiety and body weight management in rats. During our study, we treated the animals with doses of L-lysine for 20 days and then assessed their behavior. Interestingly, we noted that L-lysine had a significant anxiolytic effect, meaning it helped reduce anxiety-like behaviors in the rats.

While the treatment did not impact their food intake, we observed a reduction in body weight. Measurements showed that after repeated L-lysine treatment, levels of serotonin in key brain areas increased, which is often associated with improved mood and reduced anxiety. We also found that a metabolite of serotonin decreased, suggesting that L-lysine might help in preventing the breakdown of serotonin, thus supporting its uplifting effects on mood.

The in-silico analysis reinforced our findings, indicating that L-lysine has a strong connection with monoamine oxidases—enzymes involved in serotonin degradation. These insights suggest that L-lysine may inhibit the breakdown of serotonin, contributing to its calming effects. Overall, our study indicates that L-lysine holds promise as a natural anxiolytic agent and might aid in body weight reduction through its influence on serotonin levels.

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've used L-lysine for managing Alzheimer's, vertigo, cold sores, and also for treating a cat with feline herpes. I misordered the 1000 mg tablets instead of capsules but find the product effective. I typically prefer capsules since they’re easier to swallow. While I haven't noticed a marked difference between brands, as long as it’s "free-form" L-lysine, it works well in aiding various health issues, including Alzheimer's management.

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.
