"i take flax and borage oil together"

I suggest that you stop taking the borage oil, and increase your flaxseed oil consumption instead.

"Because GLA can be formed from linoleic acid, it is difficult to determine the extent the effects are due to GLA vs. linoleic acid. Most sources of GLA are much richer in linoleic acid than GLA. For example, evening primrose contains only 9 percent GLA, but contains 72 percent linoleic acid. "

"A recent clinical study demonstrated that approximately 1.5 tablespoons of flaxseed oil increased tissue levels of EPA com-parable to those levels achieved in studies using fish oils. The key to achieving high tissue levels with flaxseed oil is restricting omega-6 oil intake. To do this, simply eliminate or avoid vegetable oils rich in linoleic acid. The results of this recent study are significant for several reasons with the most important being that flaxseed oil can be used instead of fish oils. "
