For healthy arteries with vitamin C

I can only recommend this product. I believe everybody should use this product every day until the end of their lives which hopefully will not come very soon. This product is an excellent economy pack for long-term use, without additives, and it will take care of my arteries for about seven months. Highly recommended !

This product indispensable against Herpes infection. The lysine binds the arginine which is the essence of the virus. If you start using it in time, your mouth won't hurt.

Now foods l lysine

Good quality product and nice big size container that will last a while. To make it easier on my stomach I would prefer to mix it in a smoothie or oatmeal. There isn't a strong flavor so it works.

I started taking L-Lysine to support my immune health during cold season, and it has become part of my routine. I notice steadier energy and fewer flare-ups from occasional blemishes

很好!

Every month, I have to buy a lot of things. If I were to evaluate them one by one, I would be very frustrated. So I specially made a template. When you see this passage, it means I am very satisfied with this product. Later buyers can purchase it with confidence. Of course, I am not an irresponsible buyer. If the product is not good, I will also take the time to review it carefully

High quality

Just good quality, no fillers. Easy to dosage the powder instead of tablets or capsules with all extra unwanted ingredients. Big package size. It benefits me for my diet. It has a neutral taste and pleasant composition. I use it frequently for energy and training. I am not aware of muscle benefit, but probably indirectly it will.

L-lysine great amino acid

There have been times when I feel my body has needed l-lysine. If you are someone who suffers from cold sores - l-lysine can help. If you get cracks in the corners of your lips, l-lysine can help. If you are struggling with viruses - l-lysine could also help you to fight them. L-lysine could make you stronger and get over these things faster. Great stuff - I could see the benefits on myself taking this on many occasions.

Natural amino acid that supports your immune system

This amino acid helps your immune system to rebuild. Especially helpful if you've gone through an illness. Great quality product with clean ingredient list. The size will be enough for a long time. Make sure to not use it indefinitely, since a big increase in any particular amino acid intake can cause imbalances with other aminos in your body.

Good for people and cats too. Maybe even dogs (I'm not sure, as I don't have any).

I've been using this product for both me and my cats. I have a poor immune system and get colds easily. So does one of my cats, Twinkie, who was taken away from his mama cat way too early after he was born. He was constantly having sneezing fits, runny eyes and conjunctivitis. It has benefited us both tremendously. The human dose is 1/4 level tsp daily. The cat dose is 1/8 tsp 2-3 times daily. This size bottle contains about 822 servings, so will last for a long time.
