Omega-3 does good for what ?

Prostaglandins: Hi. Omega-3 fatty acids are essential in the diet (our bodies can't make them). They are used to make prostaglandins, a family of small, hormone-like molecules with very diverse physiologic effects throughout the body.

Multiple: The strongest benefit is the effect on lowering triglycerides. But there is lesser data in regards to it's benefits for helping with depression, decreasing systemic inflammation in the body, "flexibility" of blood vessels and protection from cognitive decline/dementias.
