Supplement Description

What is Lysine? 

Lysine is one of the amino acids termed as essential - this means that the human body cannot synthesise it and therefore it must be consumed through your diet. Lysine is a necessary building block for all protein in the body, making up the structure of all cells and tissues in our bodies. 

Why take Lysine?

The richest dietary sources of Lysine are found in meat and dairy produce, so it can be difficult for those who choose not to eat animal products to get enough through their daily diet. If you are concerned you might not be getting enough through the foods that you eat then this convenient one-a-day tablet provides an easy way to top up levels within the body.  

Just Vitamins L-Lysine supplement provides 800mg of high-grade ingredient in a convenient tablet suitable for vegans and vegetarians.

Product: I’m taking these after researching about the therapeutic effects for a cold sore problem and the Health benefits in general
Service rating: Great service, quick despatch and very happy with the product. I'll definitely use them again.
Product: Keeps cold sores away! I can't tell if it works because I don't get a cold sore every month any more! It must!
Service rating: By delivering the order!
Product: It never arrived unfortunately
The delivery to Ireland was fast, the pills have a good size, much easier to swallow than any other that I bought before.
Service rating: Prices are very competitive, the range of products is very wide and being added to regularly - and the delivery is speedy and efficient. The web site is really easy to use too.
Product: Easy to take, and recommended by some scientists as an antiviral supplement. My immune system isn't great, and in these pandemic times, I believe that this supplement could help protect against Corona-type viruses as well as the documented DNA viruses. This isn't an established fact - but I think it makes sense for those of us who are not well to have this as an extra defence.
Service rating: Great, arrived fast. Good price.
Product: I take these to try and prevent cold sores - whenever I feel like I might be getting one I take a few of these tablets, haven't had one since I started taking them (could be down to several factors but I really do think these help).
Discount given. Delivered speedily. Packaging now recyclable. All good😊
As excellent as ever. I’ve been buying from them for years.
I am in no position to make comment. Due to some mix up, I thought I had placed an order with "Natures Best" of Tonbridge Wells, but I failed to notice that when I selected "Vitamins" (as one would from Natures Best) I found that there was no slot for Account number, so I just went through as a guest. The pills duly arrived quite promptly. Thank you. Goodbye.
Easy to use website. Clear expectation on delivery.
Great quick service
Service rating: The vitamins I ordered came the next day. Brilliant service. Will order again.
Product: I get monthly cold sores and since taking L-Lysine I’ve not had one for 2 months
