The 40mg/kg would put the requirement for beneficial results reported in the study between 3,600 and 4,000 mg per day! A BOTTLE of some cheap stuff is $7.00 (Swanson brand) - that's the good news. The bad news is that there is only 1,500 mg in the entire freaking bottle. So you'd basically take a bottle with breakfast, a bottle with lunch and a bottle with dinner. I guess an alternative would be to eat 15 Lbs of blueberries a day and tape yourself to the toilet...
