Nutricost L-Lysine Powder 1KG (2.2lbs) - Pure L-Lysine, Non-GMO, Gluten Free

Use for my cats they eat it no problem.

I ordered this product early Aug and just open it today (10/19/2020). Upon opening the powder are all over the bottle thread and all over my counter top. As shown in photos, the foil is unsealed and you can see burn mark on the top and under plastic cap too. Its beyond my return window and I guess, its going into a garbage. How can you trust whats inside this bottle.

I’m taking chemo that can cause mouth sores. When my oncologist told me she’s putting me on this new “med”, I logged onto my metastatic breast cancer Facebook group and many of the members told me to get this and my mouth will feel much better. So far, so good! I just add some to my coffee in the morning.

This seems to work! Thank you!

I find this great value for money but be aware that this formula has larger grains than most do. It is more crushed looking, than powdered. I added a photo but it doesn’t capture it particularly well. I use this as a supplement for rescue/stray cats to boost their immune system (I mix it into their diet). This formula is so large and heavy that if mixed into kibble, it sinks to the bottom of the dish like salt would. Other formulas I have found are significantly lighter and finer. If you were trying to dissolve this, you might run into issues. As an additional note: my vet believes it is completely useless as an immune system booster. I hold onto hope.

I use this product for my feral cats and I mix it with hot water . It does not mix well. Some of it becomes very hard after putting it in water so I have to throw it out. Waist of money. I will pay more for a better product next time

This is made in Utah and I know because I contacted the manufacturer. It is not just distributed by ...., but made in the USA

This is a massive container of lysine, which is great but I was alarmed and immediately checked the expiration date to see how long I have to go through this stuff (I am using small quantities for my cat). It expires only 8 months from today! The normal shelf life of lysine is 36 months. So I have about 25% of the amount of time I should to use this massive container- it will mostly go to waste. Shame on this company for selling something with less than a year to live. This is not a bargain grocery outlet, and I trusted them to send me a product with a normal shelf life since I was obviously unable to check. Buyer beware.

I don’t know where this product was sourced but it has to be contaminated with something. I get a reaction from it every time whereas I get no reaction from 2 other brands..

Ima be honest, I purchased this by mistake, I thought I was buying L- Lysine for cats which is fish flavored but turns out this product is good for both cats and humans. The product is flavorless so I put it in my protein shake in the morning and sprinkle it in wet food for the cats. Definitely value for money. I keep good health generally so difficult to see any benefit, but at the price what do you have to lose. Boosted immune system for me and feral kitties
