Hi Keith, good to hear from you again.
By now most people will have heard of noni juice and how it helps a variety of condtions. I one I use and recommend to others is Tahitian Noni Juice which is manufactured by a US company called Morinda (taken from the botanical name of noni, Morinda citrifolia). I recommend TNJ because it is the only juice on the market which is scientifically tested for its proxeronine content and the process for doing the test is patented. Also, the man behind the discovery of proxeronine, xeronine etc, is a scientist called Dr. Ralph Heinicke. While all the other companies cite his findings in order to promote their noni products, Dr. Heinicke only endorses Morinda's Tahitian Noni Juice along with Anne Hirazumi who discovered the anti-cancer activity of noni. As for concentrations, I gave Aiesha 30ml a day and saw a result after 3 weeks. Initially, I split up the 30ml to 2 teaspoons every 2 hours. The reason being that the liver releases proxeronine into the bloodstream every 2 hours and this in turn is converted into xeronine (which is what helps the cell regeneration). However, this became impossible to do when Aiesha started school full-time so I just gave her 15ml in the morning and 15ml before her evening meal. For adults 30ml in the morning and 30ml in the evening is usually recommended (in particular for chronic illnesses) but I find that most people do well with just the morning dose (after all it is an expensive product!). Incidently, Morinda also do a TNJ Concentrate which I haven't used as it is not available here in the UK. There is also a noni cream which I have managed to get hold of but didn't really feel that I was getting a result. Before anyone tries any brand of noni they should visit www.morinda.com,
click on "Products" and then click on "Tahitian Noni Juice Footprint" to compare the content of all the noni's on the market.
As for you morning coffee, just wait 30 mins after taking the noni, this is the time it takes for the xeronine to synthesised by the proxeronine and proxeronase. When you eat, the xeronine will bind with the proteins from your food and do its work.
Hope this answers your questions.
