Review Details
Fast delivery, always excellent service
Great product for a good price and fast delivery. Thank you.
Good and fast service
The person who took the order was extremely helpful. The order arrived very quickly. The prices are also very competitive.
Service Rating: I have said it before the postage service of the products ordered from the UK to Europe is excellent. Goods are always withing 7-8 days upon placement of order. I am in fact repeating myself. I guess you can say standards have not dropped.
Product: I have stopped taking them for a while. I.e. a short break.
Service Rating: Very good- as usual.
Product: Very good packaged well..
Delivered product promptly, easy to order, no problems.
Service Rating: This is my first purchase from JustVitamins. Great product, value for money and speed delivery. I will be trying other products from this company
Product: Great product, it definitely works
Great service
Service Rating: Price, quality and delivery are generally good. However, they are often 'Out of Stock' for long periods on some items which requires my sourcing from elsewhere ... not good for them as I prefer to order everything from one place!
Product: Very effective ... but I need it with the same dosage in L-Carnitine 1000mg which is too often 'Out of Stock'. They do have L-Carnitine 500mg but this works out at twice the price... so leads me to source elsewhere!
Service Rating: The website is user friendly, the ordering process simple, the information on the products is good. Delivery was quick, packaging good.

Been on the pills now for a couple of weeks but have noticed no discernible change which is a little disappointing
Product: Taking this with Pycnogenol which combined is reportedly a cure or helps alleviates symptoms of Erectile Dysfunction. Been taking for two weeks with no discernible difference. So very disappointed at this stage but will complete the 90 day programme
Very efficient and good service. Received products right on time. Quality very good.
Quick steps, good packaging, Will definitely be purchasing again.

Fast and efficient service
Service Rating: szybka dostawa, dobrze zapakowany towar, ogólnie dobra informacja o produktach na stronie.
Product: nie daje skutków ubocznych, kapsułki niezbyt duże, dają się łatwo połykać, ogólnie samopoczucie mam dobre, ale za krótko używam, żeby konkretnie coś powiedzieć
Service Rating: The cost of the products purchased was considered most reasonable and although I live in Spain I received the parcel within eight days.

I am not over keen of the sealed packets and would prefer a container with a better seal.
Product: I feel that my circulation has improved in my legs, but I think I need a little longer to give a full evaluation. In my experience it is best not to give a final rating until one has been taking that particular supplement for an extended period.
Service Rating: Very fast product!
Product: Very good delivery!
Service Rating: thanks
Product: Good stuff , they are working just fine if you take in my case only 1 per day.
Service Rating: Everything ok, I would recommend them for the quality of the products and for the speed of the delivery
Product: very useful for the decline of the blood pressure and for excersice. I take 4 pills for my train and I see results
yes, it took three weeks for them to arrive.
I'm 83, and many websites tend to pester and advertise afterwards. I'm not used to that. I went to you for Lutein in the first instance, and have decided to stay with you as long as you continue to be helpful but not pushy. (John)
Service Rating: Great service and products. Would definitely use them again
Product: Excellent product with evidence based uses which is much needed
Good service. No complaint.
