Service Rating: Very prompt service, would definitely recommend
Product: Very effective, works quickly for me.

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: I ordered the vitamins easily online and at a much cheaper price than in stores. They came quickly and easily through the door. All around, a great service!
Product: I take 5htp in the winter to help me regulate my sleeping and moods during the wintertime. I take 2 before bedtime, and perhaps it's the placebo effect or perhaps it's real, but I go into a very restful and deep sleep quickly after.

Service Rating: Excellent, quick and the helpline works!
Product: I only take one if I don't have an early start, but it is really strong and works exactly as it says. My mood is better, possibly because my sleep is so refreshing now.

Service Rating: The site works as it should do with a dedicated page for re-ordering items you've bought before.
They could improve this re-order page by allowing you to delete items that you have had problems with and have no intention of buying again, especially when they have refunded the cost of the item(s) complained about.
Product: I find they have the calming effect claimed for this product.
