These are the supplements I am trying, but most say to take with or without food. Which ones do most of you think work better on an empty stomach?

D-3 (my level was 38, so in a normal range) 2,000 IU
Benfotiamine 150-300
R-Lipoic Acid 100 mg
CoQ10
Krill Oil Mega Red
Nutrametrix multivitamin

I still hesitate to use B12 since my level was just under 2000. I had a full blood panel done and both doctors I saw said not to worry about it, but taking more seems unnecessary. I asked for a test to see if I am not absorbing it properly, but they acted like I was insane. Anyway, I am going to start with these and would appreciate any input.

B12 is the most critical to use on an empty stomach.

Some studies show lipoic acid also is less absorbed with food.
This may not be a factor if you use the new solubilized form
NaRALA (called stabilized, which is much more absorbed quickly).

Benfotiamine has studies showing food does not matter.
And your CoQ-10 if in an oil capsule would be best with food.
If the new type like Qunol, this is less critical because that has been improved with solubility issues.

Vit D is easily absorbed with or without food.
