Excellent!!

Excellent!! An essential amino acid for the body. Being a vegetarian I take it as a supplement to combat anemia and have a better absorption of calcium. My skin is more elastic and my hair feels stronger and nourished. My immune system is stronger. Works. If this review was useful to you please like it.

Bought this for my cat

My cat is prone to have watery eyes, so I bought this for her. When she starts squinting one of her eye and it gets watery, I will feed her one capsule a day. I open up the capsule and sprinkle it all over the wet food and blend them. Usually, after a few days, her eyes will get better and I can stop adding lysine into her diet! Overall, really good stuff!

I usually take it in the morning. The ingredients seem like a superfood. I would recommend

L-Lysine

Great quality, great for herpes, great for the immune system. I am not sure if it is better than tablets, but logically it should be.

Simple ingredients. Worth recommending—especially if you have pets at home.

The ingredients are simple and suitable for people to take. Because of the ingredients, it can also be given to pets (especially cats) by mixing it into their food. Since it comes in capsules, the serving size is easy to control, making it a great supplement for both people and pets. It’s also much cheaper than other brands (about half the price). Based on what was found, this manufacturer hasn’t had lawsuits or disputes in the past related to ingredient problems, so overall it’s a supplement that’s worth recommending.

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach—no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and I love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!|

This product works well for cold sores, I find I have to take a large quantity as soon as I noticed the start of one.

For my herpes

I have herpes, and my blisters cleared up in just two days after taking this. I wish I had known about the amazing benefits of lysine sooner. I recommend it to people with weak immune systems and people who have herpes like me.
