Did your doctor tell you to take iron?
Was this based on testing?

Males should not use iron unless they are told to
And supervised by a doctor.

Cod liver oil is high in retinol... Too much
of this can be toxic and affect the pressures in
the brain. Use fish oil or krill oil for your
Omega-3s.

And test your blood sugar on the OLE.
Type 2 diabetics may see a better
Response to insulin resistance but you
Are using insulin now... Correct?
It may over time with the OLE improve your
Insulin response and you may need adjustments
In dose of the insulin. But I really think not
In your case.

Chronic infections tend to raise blood sugars
So as those recede your blood sugars may
Fall a little for that reason.
