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.

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!|

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.

Reliable Lysine for Daily Support

The quality of NOW Foods Lysine is excellent. The ingredient feels pure and well-formulated. The size of the veggie capsules is easy to swallow. The package keeps all 100 capsules fresh and secure. I notice the benefit in supporting immune health, collagen production, and overall wellness. Taking lysine regularly helps fill nutritional gaps and maintain daily body functions. The taste is neutral since it comes in capsule form, making it simple to take every day.

Great supplement at fair a price...

We take these religiously! They work perfectly for our needs and are not too large of a capsule, though they are not small, either. I would recommend these to anyone. We recently made the error and ordered the tablets version of these and, while they work well, I cannot wait to go back to the capsule.

Love this!!!

I have been taking L-Lysin for a long time as it helps me with cold sores that I use to get all. the time. This is a new one I started to take in capsule form and I LOVE IT! All others I was taking before were so big and hard to take. Highly recommend this supplement.
