Although I eat blueberries, I probably don't eat them often enough. I also tend to suffer from 'blue mouth' disease if I eat them too often (meaning my teeth turn all blue).
I looked over some of the blueberry supplements out there, and am not sure which to choose, if any.
LEF's is a bit expensive, for the anthocyanins per capsule (12.5), assuming their newer product contains the same as their old one did. It's a bit hard to tell now, as they seem to purposely not mention the amount of anthocyanins in their extract. They now include Aurora Blue, but at 50mg I'm not sure it's really enough to do much. They also don't mention how much Pterostilbene is in their product, although they mention it in the product description.
Natural Factors has their BlueRich extract, which appears similar to LEF's in terms of anthocyanin content (12.5), but with less variety of extracts included. They are a lot cheaper though. There seems to be anecdotal reports of it lowering blood sugar + triglycerides (at iHerb anyway), possibly due to Alpha-glucosidase inhibition? This may be a good or bad thing, depending on a person's glucose levels.
FruitFast has a gel extract with 40mg of anthocyanins. But they are the most expensive, not available anywhere besides directly ordering from them, and I'm not sure how good a company they really are. They also claim powdered extracts have no health benefit, which doesn't seem so believable to me (sounds like a marketing ploy).
And then there are also bilberry extracts, usually at 25% anthocyanins. Their benefits should be similar, if not the same, as North American blueberries, so I have been considering them instead. They also have that whole 'vision benefit' thing going for them, but I'm not sure if the studies back that up so well. Jarrow and LEF have reasonably priced bilberry extracts.
So... are any of these worth supplementing with? Anybody out there ever notice vision improvement from using bilberry? Or should I just try to eat more blueberries and save my money?
