Now if you are not interested in this stuff and think is a myth ...read no further.
I found some today in a health food shop.Small bottle 300ml...easy to carry in handluggage as so tiny. No preservatives, no concentrates, no added sugars, 100% raspberries.
as you only need 10ml a day then this would last 2 people 30 days.
Is by berry sweet australia www.berrysweet.com.au and $7.95.
