I have purchased a acai berry based drink and it was great… It was like a red wine without the alcohol content.
A glass a day was all that was needed and after a short period of time I had a lot more energy and felt a lot better in myself.
The only draw back was the cost of each bottle. If it wasn’t so expensive I would still be drinking it now.
Someone previously mentioned autism (as a joke?) I personally know a couple with a autistic son and that acai drink I mentioned helped him heaps, it calmed him down, he slept better etc and he was only given about a cap fill a day.
I believe in that particular acai berry drink but have never had anything else.
