What are the alternatives for getting omega 3 and vit d if you can't take fish oil or dairy and can't sit in sun long due to nature of your job?

Alternative. Vitamin d3 can be taken by mouth. The need is decided by a blood test. Omega 3 and omega 6 fatty acids are essential to life and the top of the cascade that leads to omega 3 formation is Alpha linolenic acid, the top of the omega 6 cascade is linoleic acid. Both of these essential oils are present in canola oil. Fish oil supplies eicosapentoic acid (epa) a metabolite of linolenic acid.
