It's not what it seems on the bottle
I initially thought this was another of those revelations where a doctor finds a miracle cure for a variety of issues. e.g. teeth whitening, weight loss, prostrate problems, etc. Usually it involves a unique combination of natural ingredients from exotic places that only s/he has been able to put together. Inevitably they're in short supply - so buy quickly. And there are other incentives to buy asap.
From Dr Sarah Brewer this is similar except it's only one ingredient - extra virgin olive oil but an extra special one. One that is grown in a volcanic area.
The difference is this product is available elsewhere, online.
The price of a 250ml bottle of Ancient Roots EVOO is £34.95. Online 'volcanic extra virgin olive oil' can be bought for £12.45 for 250ml or £21.50 for 500ml.
Of course, the Ancient Roots oil may be 'the' best quality in the world but in the video presentation there is no mention of potential (inferior) quality oils or comparison studies.
Shockingy, Dr Brewer appears in an advert on a webpage for 'originsdiet' for Ancient Roots where the price is £49.95 for a bottle! The size of the bottle isn't stated but using a magnifying glass on the image its size is 250ml.
If you think EVOO would work for you, or you just want to try it, I would recommend you do some online research for volcanic extra virgin olive oil and compare prices.
