Can I Take A Combination Of Fish, Flax And Borage Oil While On Medication For Mental Health Issues, Acute Constipation, And Vitamin D3 Deficiency?

I take fish oil to treat high triglycerides. I saw a combination of fish, flax and borage oil. I take meds for mental health issues, acute constipation, atrial fibrilation tendencies, low potassium/magnesium, vit d3. How will the oils mix with my meds and what are the benefits?
