Long story short, I’ve been taking this L-lysine for about 8-9 months only once a day and sometimes I’d skip a day when I forgot. I went to the doctor for my bloodwork a little over 4 months ago and it came back that I have high cholesterol. That’s very weird for me because we have no family history of this in my family, I’m a good weight, exercise and eat a pretty healthy and balanced diet. After researching and then calling my doctor with the news, I stopped taking L-lysine because I found that it can raise your bad cholesterol and it should only be taken 3-4 weeks MAX. It’s been a little over 4 months now and I’m happy to say that my cholesterol is now back to normal, the only change I made was I stopped taking the L-lysine supplement. I’m sure it can help people, but I do warn you to only take it for up to a month and then take a long break in between. Hopefully, no one has this happen to them and hopefully I have no permanent damage or issues later on because of it. God bless!

L-lysine is an amino acid that our bodies can't manufacture but that is essential for human health. Food and/or supplements are our only sources of this amino acid. L-lysine is important for proper growth and it supports other amino acids in converting fatty acids into energy and helping to lower cholesterol. Studies indicate that lysine helps the body absorb calcium and it plays an important role in the ongoing health of bones and connective tissues including skin, tendons, and cartilage.<br /><br />While most people get sufficient l-lysine from their daily diet, there are some people, such as athletes, vegans, and burn patients, who can benefit from supplementation of lysine. The following are some of the potential benefits:<br /><br />- It is thought to improve athletic performance in endurance athletes<br />- It may reduce bone loss associated with osteoporosis<br />- It can help treat the symptoms of angina when accompanied by vitamin C<br />- By preserving calcium, it benefits your teeth, cartilage, and bones<br />- It is thought to help improve mental well-being and ward off fatigue<br />- Regular supplementation of lysine is believed to prevent outbreaks of herpes virus such as cold sores<br />- There may be potential for weight management benefits<br /><br />Daily supplementation of lysine in too high of levels (several thousand milligrams) can lead to gallstone formation or the development of kidney disorders. This amino acid can also react with certain antibiotics to produce toxicity. At 500mg, this lysine supplement from NOW is a good low-dose option.<br /><br />I've been happy with the NOW Natural Products line. They've been producing quality nutritional supplements for 40 years and remain a top-selling US brand.

I have been fighting re-curing Shingles. It helps more than anything else I took.

50 year old female taking L-Lysine for skin and collagen support, experienced scary heart palpitations and skipped heart beats. Took a few days to figure out the cause so decided to share here and maybe save others an unnecessary trip to the ER.

Incredible how great it works with the skin and acne. I can't take arginine it breaks me out too hardcore but this stuff saves my skin.<br /><br />6 MG of it and all my arm acne and chest acne vanished as if it was magic. Wounds heal faster and my skin is silky smooth.<br /><br />10/10 product.

I use this with other herbals to keep my old man skin clear and no nasty spots or rashes.<br />It won't fix ugly.
