soybean oil taste like it went bad

Posted by iHerb Customer on July 9 2013 | Verified Purchase

I do not understand why supplement companies use oils that can so easily become rancid. The rest of the ingredients look fine. But, when I cut open the capsule to test the freshness, both I and my boyfriend were sicked by the taste that worsened by the second. Natural Factors does make other good products like biosil which I'll continue to use despite this poorly formulated supplement. I'll stick with eating real blueberries for now.

Thanks for your feedback!

Hard to believe it came from blueberries

Dark rancid tasting sludge that comes in a heavy duty capsule. Makes me feel ill after consuming it. Hard to believe that it comes from blueberries - if I was to guess, I would say it is from the leftover residues of an industrial blueberry processing plant. I would doubt that anything that rancid tasting has much antioxidant capability.

Thanks for your feedback!

No marked improvement.

I take 3 pills 3X a day and I'm still slow and dumb. I know this takes time to improve concentration, but I think wild blueberry extracts will work better.

Thanks for your feedback!
