spectracell is good for 80% of the readings
Fat soluable are stored and vitamin D is what is left from 3-6 months so it can give false normal readings
Allows test vitamin D 25 oh and go by that not spectracell
More so from vitamin D not fish oils. People take too much fish oil can knock out a natural balance of EFA resulting in its own set of problems. I recommend doing nutra eval from genova more bang for your buck. If you need help interpreting it. I am one of the best in the field for doing that.
