Flax seed oil (1000 mg from WM works) is harmonizing and brightening in my experience
(with other clinically proven health benefits, as well),
and probably due to the omega 3 fatty acids -
probably similarly to cod liver oil -
and doesn't taste bad.
See World University & School's Omega 3 Fatty Acids wiki subject page here -
(WUaS is like Wikipedia with MIT OCW).
New Omega 3 developments you know of?
Related harmonizing effects from something you eat?
Please add them to WUaS ...
kind of a trip ...
Happy baby mongolian and camel ...
and different reality ...
