Flaxseed oil has higher milligram quantities of Omega-3, Omega-6 and Omega-9 than fish oil. So why are fish oil capsules better than flaxseed oil?
Flaxseed oil contains short-chain Omega-3 fatty acids and the human body can convert these short-chain Omega-3 fatty acids with great difficulty into much lower levels of longer-chain Omega-3 fatty acids. The conversion rate is between one and five percent. It is only the long-chain Omega-3 fats that have the health benefits. This is not to say that flaxseed oil is bad. It is just not very good compared to fish oil because of the very inefficient conversion of the fats found in flaxseed oil to the long-chain Omega-3 fats found in fish oil.
