The best supplement! BUT pills are quite large if you aren't used to swallowing pills often
⭐️⭐️⭐️⭐️⭐️ Great for Immune Support & Skin Health! I started taking L-Lysine supplements to help with my cold sore outbreaks, immune system and overall wellness, and I can honestly say they make a difference. They’re easy to take, gentle on my stomach, and I’ve noticed my skin looks clearer and healthier since adding them to my routine. I also feel like I recover faster whenever I start feeling run down. Definitely a supplement I’ll keep in my daily lineup! The only down side for most people is that the pills are quite large. Some find them hard to swallow!

Excellent quality and effective supplement!
I have been taking NOW Foods L-Lysine 1000 mg for a few weeks now, and I am really happy with the results. L-Lysine is an essential amino acid that I started using mainly to support my immune system and promote collagen production, and I can definitely feel a difference. One of the things I appreciate the most about this supplement is its double strength formula, which means I only need to take one tablet per dose instead of multiple smaller ones. The tablets are a bit large, but they are coated, making them easier to swallow. I’ve also noticed that my skin feels healthier, and my recovery time after workouts has improved. Additionally, it has been great for keeping cold sores under control, which is a big plus for me. Overall, I highly recommend this product to anyone looking to boost their immune system, support skin health, or improve their body’s collagen synthesis. NOW Foods is a trusted brand, and this supplement is a great addition to my daily routine! Will definitely repurchase. ✅

Perfect companion for collagen
This is a product that i use for health benefits to supplement marine collagen to have a full array or amino acids, as L-lysine isnt present in collagen It really helps my weight training and strength straining The ingredients are simple. It has no smell. It is a rather large pills. Keep that in mind. I did not see an effect on my skin or sleep quality

Effective
I got these when I started taking a GLP that seemed to trigger cold sore every other week. Taking these on a regular basic helped curb and then stop the outbreaks completely. This L0Lysine is the immune boost my body needed! The pills are rather large and do take some mental gymnastics to swallow. I would actually prefer if they cut the size in half and double the suggested serving. Nevertheless, I can swallow them down and they dissolve with no ill side effects. Like stated prior, the effectiveness seems superior to other brands I have tried.

Great supplement
My husband takes L-Lysine daily as a preventative for cold sore breakouts on his lip. This seems to do the trick. He rarely has eruptions anymore. He also takes Ashwagandha to help reduce stress as stress can be a trigger for flare ups. The combo does great for him.

Reducing Outbreaks
I've been taking a lysine supplement for a year, and it’s been really helpful. Lysine is an amino acid that’s supposed to help with your immune system, skin, and even make calcium work better in your body. I started taking it mainly to stop cold sores, and since I started, I’ve had fewer and less severe outbreaks. One thing to note, though—the pill is pretty large, so if you have trouble swallowing big pills, this might be an issue. On the bright side, it doesn’t have a bad taste, which is a relief. I’ve also noticed that I haven’t been getting sick as often, even when others around me were. Just make sure to stick to the recommended amount, because taking too much could upset your stomach. I haven’t had any problems, but it’s always good to be careful. Overall, I think lysine is a great supplement if you want to boost your immune system, keep your skin healthy, or prevent cold sores. Just keep in mind that the pill is big, and as always, it’s a good idea to talk to a doctor if you’re unsure about taking it.

Saves me from cold sores
I’ve been using NOW Foods L-Lysine 1,000 mg regularly, and it has made a noticeable difference for me. I used to get cold sores monthly, and since adding this to my routine, I’ve had far fewer outbreaks. What I really appreciate is that taking lysine consistently helps me prevent flare-ups, so I don’t have to rely on medication as often. The tablets are good quality, easy to take, and the dosage is convenient since it’s already double strength. What I like: Has helped reduce how often I get cold sores Allows me to rely less on medication Good quality and trusted brand Simple, affordable supplement Overall: This has become a staple supplement for me. If you’re prone to cold sores and looking for a supportive, preventative option, this is definitely worth trying.

Large tablet
Too soon to tell results, however benefits sound great for post-workout recovery. This is a great brand and I went with 'Now' after much research. I take multiple supplements from this brand with great satisfaction. Very large tablet. May be difficult to swallow for some, especially if broken in half.
