I would be careful about taking supplements, including any non-topical magnesium. You have a lot of potential for having the contaminants interact with excess iron. I would though take vitamin D to protect from the problems of excess iron, and whatever it takes to reduce those triglycerides (except polyunsaturated fats such as krill oil or liver oil or fish oil).
I guess in this situation I wouldn't take the tocotrienols in your supplement.
