It's the best oil you can buy.
Omega 3's (which are contained in flaxseed oil) can increase insulin sensitivity in muscle,decrease it in fat,reduce body fat, decrease muscle damage and soreness,and decrease disease or injury-induced inflammation.
I want also to suggest you to supplement your diet with fish oils which are rich in EPA and DHA,that are better suited to the health benefits I mentioned above.Flaxssedf oils has a lot of LNA, but that omega 3 has to be converted into EPA and DHA.
