Does Omega-3 Work?

Since omega-3 fatty acids are naturally found in food, does omega-3 work as well when it comes in the form of a supplement? A diet high in omega-3 fatty acids could promote weight loss, but this does not mean that taking a supplement will also have this effect. However, studies show that omega-3 may decrease triglycerides and help with fetal brain and eye development.

 

Does Omega-3 Really Work?

Many people are interested in supplements containing omega-3 (short for omega-3 fatty acids). There is good evidence that omega-3 may be beneficial for numerous different conditions. However, omega-3 fatty acids may not be the miracle cure-all that they are sometimes claimed to be.
 
This article will discuss omega-3 fatty acids for several different uses, including:
 
  • Weight loss
  • Heart health
  • Mental health
  • Pregnancy, breastfeeding, and childhood development
  • Aging.
     

Does Omega-3 Work for Weight Loss?

It is too early to tell.
 Studies with mice and rats have sometimes shown that omega-3 fatty acids may have a role in weight loss and fat loss, but human studies in this area are lacking. Keep in mind that omega-3 supplements are not free of calories or fat. It is reasonable to expect that a healthy diet that is high in omega-3 fatty acids (usually from fish) could promote weight loss, but this does not necessarily mean that taking an omega-3 supplement will also have this effect.
