I have a total of 4 supplements that might be causing me stomach problems. I either get really bad hurt burn for days or it goes straight through me. I'm wondering what one I should add back in first. Which one is the most important and or might not be the culprit.

They are:
R-Lipic Acid 100mg (1 per day)
Acetyl L-Carnitine 400mg plus Alpha Lipoic Acid 200mg (3 per day)
Co Q-10 300mg (1 per day)
Members Mark Omega 3,6, 9 soft gel 1000mg of fish, flax, evening primrose and borage oils. (2 per day)

Any thoughts?

Thanks

Ps. I'm going to post this in the supplements group/forum/board-(what ever it's called) as well.
