Quantum Health SuperLysine+ Advanced Formula Immune Support Supplement

Lysine aids cold adaptation mechanisms

Likely Very Effective

Xue C, Zhu S, Li Y, Chen X, Lu L, et al. Cold exposure accelerates lysine catabolism to promote cold acclimation via remodeling hepatic histone crotonylation. Environ Int. 2024;192:109015. doi:10.1016/j.envint.2024.109015

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.

After years of suffering from occasional cold sores, I decided to try this product based on reviews. I switched from daily L-Lysine supplements to taking these only at the first sign of an outbreak. Recently, I felt the tingling and took three tablets. To my astonishment, the cold sore was gone by morning! This product truly works without causing stomach issues!

I experienced genital herpes often due to an hour of hypothermia. On the very first day when I felt pinching, I took three lysine capsules on an empty stomach, and the next day, the pinching was gone, and redness did not appear. It worked!

Lysine improves herpes symptoms

Shingles details

Walsh DE, Griffith RS, Behforooz A. Subjective response to lysine in the therapy of herpes simplex. J Antimicrob Chemother. 1983;12:489.

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.

Years ago, during my first shingles outbreak, I was hesitant to take the antiviral prescription due to potential side effects. A health food store lady advised me to take Quantum Health Super Lysine+. I took it three times a day, along with topical L-lysine, which stopped the itching and spreading instantly. I now keep this product on hand for any stress-related outbreak and it works every time. I’m grateful it exists and know there are no bad side effects.

RCI001 shows promise for Sjögren syndrome

Based on 2 Researches

Kang H, Jung YH, Moon J, Ryu JS, Yoon CH, et al. Efficacy of RCI001 as a Therapeutic Candidate in a Primary Sjögren Syndrome Mouse Model. Cornea. 2025;44:226. doi:10.1097/ICO.0000000000003696

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.

This is an excellent natural immunity stimulator! I’ve taken it several times when unwell and felt better within days. I even gave half a tablet to my 5-year-old child, who coped well. I'd recommend it without hesitation; you won't regret it!

My husband suffered from chronic cough and a runny nose for three years, exacerbated by moving to the Urals. After trying various prescriptions, I decided to give him immunity capsules from Iherb three times a day. Remarkably, after four days, he noticed improvement and concluded that the supplements helped him recover. I'm very pleased with the results.

High Cholesterol details

L-lysine may slow atherosclerosis

Based on 4 Researches

Behr-Roussel D, Rupin A, Simonet S, Bonhomme E, Coumailleau S, et al. Effect of chronic treatment with the inducible nitric oxide synthase inhibitor N-iminoethyl-L-lysine or with L-arginine on progression of coronary and aortic atherosclerosis in hypercholesterolemic rabbits. Circulation. 2000;102:1033.

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.

This is a high-quality supplement with effective ingredients. Lysine helps with herpes and boosts my immunity. The garlic odour is negligible, and the capsules are easy to swallow. Overall, it's a reliable remedy for colds and provides support for high cholesterol as well.

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.

After taking this for several months during winter and early spring, I remained healthy, even avoiding a runny nose, which I had considered a fantasy. I've spent years in a constant state of anxiety, yet after stopping the medication, I realised how anxious I had been. Remarkably, for four months on this drug, I forgot what feeling anxious was like. It not only boosts immunity but significantly alleviates anxiety too. I experienced no drowsiness, only calmness.

Based on 6 Researches

Thein DJ, Hurt WC. Lysine as a prophylactic agent in the treatment of recurrent herpes simplex labialis. Oral Surg Oral Med Oral Pathol. 1984;58:659.

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.

Herpes details

L-lysine helps prevent herpes outbreaks

Questionable

Based on 3 Researches

Jamgochian M, Alamgir M, Rao B. Diet in Dermatology: Review of Diet's Influence on the Conditions of Rosacea, Hidradenitis Suppurativa, Herpes Labialis, and Vitiligo. Am J Lifestyle Med. 2023;17:152. doi:10.1177/15598276211026592

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.

ZGCD improves diabetic cardiomyopathy

Based on 2 Researches

Ji K, Han M, Yang M, Xu Q, Zhang Y. Integrated meta-analysis and network pharmacology analysis: evaluation of Zhigancao decoction as treatment for diabetic cardiomyopathy. Front Cardiovasc Med. 2025;12:1454647. doi:10.3389/fcvm.2025.1454647

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.

Magic tabletochki!!!! Two years ago, I changed my climate—moving from central Russia to the west. As a result, my immune system began to fail; I was unwell every month, suffering different colds and viruses. I tried echinacea, herbs, and wild rose from the pharmacy with no success. Then, I discovered these magical vitamins. I reduced the recommended dose and stretched a jar for 3 months, starting in January 2015. Since then, I have not been ill, only having a cold for two days. Despite a strong flu epidemic in our town this year, I didn’t even sneeze. I have not found anything better for my immune system. I highly recommend it!

Cough details

An excellent remedy for colds! My son, 26, caught a cold and spent three weeks on pharmacy medicines, yet his throat remained sore and he had a cough. When a package of Super Lysine arrived, he started taking three tablets on an empty stomach, and the illness eased. Now, my whole family takes two tablets on an empty stomach for flu prevention and to boost our immune systems. Super Lysine contains odourless garlic, echinacea, Vitamin C, and liquorice. Highly recommend!

KLS offers better sore throat relief

Sore Throat details

Passàli D, Volonté M, Passàli GC, Damiani V, Bellussi L. Efficacy and safety of ketoprofen lysine salt mouthwash versus benzydamine hydrochloride mouthwash in acute pharyngeal inflammation: a randomized, single-blind study. Clin Ther. 2001;23:1508.

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.
