Solgar VM2000

I'm thinking of taking the VM2000 multi vitamin as it seems to have most of the supplevents recommended by David. Would this be ok in addition to the oils, NAC, Lcarnitine, coenzyme q10 and alpha lipoic acid? Or would there be interactions with doxy and Rifampicin?

difficult to know where and what to start essential are lcarnitine, q10, ALA, querceten?
