As far as I know, Morinda do not make noni capsules or with added pineapple. Make sure the bottle says Morinda Tahitian Noni Juice, otherwise you may end up buying an imposter product. I've seen people in the UK buy a product called "Noni Tahiti" in a lookalike bottle thinking that it's Tahitian Noni Juice (which is actually a trademark name). If you want to know exactly what products Morinda make then you can check out http://www.morinda.com
and click on products. They do online ordering but charge $7.95 for shipping and handling so you may be better off finding a distributor near you.
As for dosage, I used to give Aiesha 30ml a day which is actually an adult dose. I take the same, first thing in the morning, 30 minutes before breakfast.
Hope this helps!!
