Effectively reduced symptoms
3 people found this helpful
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!

Prevented lip sores

I suddenly had a large lip sore that took ages to heal. After reading online about L-lysine's benefits, I bought it and took one capsule daily for prevention, increasing to two if I felt heat in my lips. Impressively, my lips returned to normal the following day, and since taking L-lysine, I haven’t had any more lip sores or swollen lymph nodes.

I was surprised! I heard that lysine is good for cold sores, so I bought it. Recently, I had pain in the corner of my mouth after a while and took 2 tablets a day on an empty stomach, as it’s suggested to take lysine that way. The swelling had subsided by the next day, and I was astonished at how quickly it healed! It appears that lysine is effective in suppressing inflammation of swollen lymph nodes.

Effective for symptoms

Swollen lymph nodes, also known as lymphadenopathy, occur when the lymph nodes—small, bean-shaped glands that are part of the body's immune system—become enlarged due to infection, inflammation, or disease. These nodes play a crucial role in filtering harmful substances and fighting off infections, and when they detect a problem, they can swell as immune cells accumulate to combat the issue. Common causes of swollen lymph nodes include viral infections like the common cold or flu, bacterial infections, and even conditions like autoimmune diseases and certain cancers.
Symptoms of swollen lymph nodes can vary but may include visible swelling or tenderness in areas such as the neck, armpits, or groin. While often benign, swollen lymph nodes may indicate a more serious condition, particularly if they persist beyond a couple of weeks, or if they are accompanied by other concerning symptoms like fever, night sweats, or unexplained weight loss. It is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment if swollen lymph nodes are persistent or concerning.
L-Lysine is an essential amino acid that plays a crucial role in many bodily functions. Unlike some amino acids that can be synthesized by the body, L-Lysine must be obtained through diet or supplementation. It is particularly important for protein synthesis, hormone production, and the absorption of calcium. Good dietary sources of L-Lysine include meat, fish, dairy products, eggs, and certain plant sources such as beans and legumes. Athletes and individuals looking to support muscle recovery and growth often consider L-Lysine supplements.
In addition to its role in enhancing muscle recovery, L-Lysine is also often touted for its potential benefits in supporting immune function and combating cold sores caused by the herpes simplex virus. Some studies suggest that L-Lysine may help reduce the frequency and severity of these outbreaks. However, it’s always advisable to consult with a healthcare professional before starting any new supplement to determine the appropriate dosage and ensure it aligns with your health needs.

Quick recovery from herpes
L-Lysine from NOW is an essential amino acid. After starting it, I didn’t experience herpes outbreaks until I missed a week on holiday, resulting in an outbreak after sleep deprivation. Once I resumed taking lysine, the herpes cleared quickly without the usual swelling. I took 500 mg, at times 2 to 4 a day, reaching a norm of 2000 mg daily, which has proven immensely helpful for swollen lymph nodes.
