Fish Oil / Omega-3s
http://en.wikipedia.org/wiki/Fish_oil read up, essential supplement here
Some experts believe that taking fish oil (in any form) can help regulate cholesterol in the body,[who?] because fish oil has high levels of omega-3 fatty acids. The regulation occurs through effects of the EPA and DHA constituents on Peroxisome proliferator-activated receptor alpha (PPARα). Besides cholesterol regulation, benefits include anti-inflammatory properties and positive effects on body composition.
