Stool is shiny and oily does that mean I should cut back on the oils?

Stop the fish oil for a week or so and see if it stops. If so, try restarting to see if it recurs. If it does, start only the fish oil at a low dose and increase to full dose over 2-3 weeks. This allows the gut to adapt and “learn” to absorb the oil better. The add back the olive oil in the same fashion.
