Easily negotiated website. Prompt delivery.
Great service. Especially like that Vitamins etc come in recyclable packaging & not plastic bottles.
Service rating: Friendly helpful staff, quality products, earth friendly packaging and delivered quickly and in excellent condition
Product: Easy to take, helps prevent me getting colds and cold sores
Service rating: My order arrived promptly and well-packaged
Product: Not tried yet, so can't comment
Service rating: letterbox friendly packaging

Service rating: All good thank you
Product: It’s for my cat who has feline herpes.
As expected the usual speedy service
Service rating: Fast delivery. The tablets come in flat packets that go through the letterbox.
Product: Taking it for outbreak of cold sores. Always works.
All very simple, clear, good quality products, good packaging, etc
Service rating: Milk Thistle & L-Lysine
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
Service rating: You can rely on Just Vitamins for an excellent service and a good quality Vitamin whatever one you orde.
Product: L-Lysine another vitamin for the me I take it for cold sore prevention and it works. If you suffer from these it's worth a try.
Service rating: excellent product excellent delivery
Product: because they were great value for money
Arrived very quickly. My only concern is that there is nothing on the packet to say it meets food quality standards.
