I took 3 of these for breakfast as an antioxidant every day for about 3 weeks and started to feel sooo sleepy and tired all the time, almost dizzy and disoriented. I couldn't understand why, then I suddenly remembered something about blueberries lowering bloodsugar or something, and I also lost all craving for sugar after I started taking it, so I ate a lot of sugar to see what would happen and after 10 min. I started to feel normal and alert again. I'm truly surprised a berry extract can have this profound effect. I give 5 stars for effect, but be sure it is right for you. I don't think this is for me.

massively lowered my blood glucose levels, causing severe hypoglycemia. blueberry inhibits alpha-glucosidase, altering carbohydrate metabolism. i have not fully recovered yet. be very careful. life extension extract was much better, did not have the glucose lowering effects.

Softgels are way too huge. My aged father won't swallow them.
