That is a good idea.

Keep the B12 and Vit D (were you tested? so you know how much to take?) If you don't want the D3 supplement, get some sun each day.

Keep the Lysine (to see if you have viral problems). And the acetyl carnitine (mito damage).
These major ones hit the big areas that are most commonly damaged or having problems.

We also have to understand "high".... the essential fat in flax oil, has to be consumed in some quantity daily. We cannot live without it. So what is "high" exactly in the studies? 5 grams? 10 grams? One capsule of the oil is typically 1 gram with about 40% ALA (alpha linolenic acid) in it. I don't think that is "high" for anyone who has to be eating it and is not typically. So understanding doses is also important.
