Nutritional supplements will only be posted to delivery addresses in the United Kingdom. Please, do not place an order if your delivery address is outside the UK. In the web page Mitochondrial Function Profile you will find some internet sites from where nutritional products can be purchased from outside the UK.
Books are dispatched worldwide.


Non UK residents - You can order any of my books but we only ship supplements to addresses within the UK. However there are 2 ways around this:

1-- And recommended-- Both of my Facebook Groups run informal ‘Buddy Schemes’ The idea is that a non-UK Group Member buddies up with a UK Group Member. The UK Member orders the supplement from within the UK and posts them to the non-UK Member and they sort out the money between themselves. You can see links to my Facebook Groups here - https://drmyhill.co.uk/wiki/My_Social_Media_Presence

2--Alternatively, non-UK members can use -


Which will ship from the UK to anywhere in the world. Please be aware that there are extra costs incurred when using this service and once the order has left our shop and can be tracked as delivered to your Reship address, we can no longer assist with any problems that arise from then onwards. You will need to liaise with your Reship correspondent.

Orders are delivered using Royal Mail 24 hour service. This delivery service is trackable upon request. We make every effort to have orders ready for collection as soon as they are paid for. Packages are collected from the practice by our regular Royal Mail postman. Collection times vary and we cannot guarantee that all orders paid for by 9.00 am will be on their way that same day. Delivery may take up to 4-5 working days from the time you pay for your order but this may take considerably longer.

​Our delivery charges are based on weight. Minimum delivery charge is £4.99 Under the terms of the RM 24 delivery service, the maximum weight of a package is 30 kg.

Royal Mail does not consider an item lost in the postal system unless 15 working days have elapsed from the date of dispatch. If your item has not arrived in the expected delivery time of 4-5 working days (excluding bank holidays & weekends), we recommend that you check with your local sorting office.


You can return a product you purchased from Sales at Dr Myhill within 30 days of purchase and you may qualify for a refund.
To be eligible for a refund, the item must be unopened, unused and in the same condition in which you received it. It must also be in its original sealed packaging that has not been tampered with. Once your return is received at Sales at Dr Myhill, inspected, and approved, we will issue a refund via the payment method that was originally used. You will also receive an email notification of the refund. If the returned item is found not to be eligible for a refund (i.e. it is not in the condition as described above), you will receive an email notification of the rejection of your refund request and the reason. We will refund the price of the eligible item(s) returned, but not the cost of posting. The cost of returning unwanted products is borne by the buyer.
