In particular, vitamin B1 (thiamine). I noticed on Cronometer that I get about 50% of the RDA for B1 (I know, RDA isn't necessarily important...). I was thinking of taking Jarrow B-Right which has 25mg of B1 (1667% of RDA). After reading the supplements thread and how vitamin C tablets are poorly absorbed, it got me thinking about how well all these things are absorbed. Would I absorb enough from the B-Right to get my B1 to 100%?

Always opt for liquid vitamins: with B vitamins, this is crucial for absorption. http://www.untrainedhousewife.com/the-best-food-and-supplement-vitamin-sources-b-vitamins
If you like peanuts/peanut butter and chicken, trust that you're getting a much more vibrant supplement from these foods as well.
P.S. Personal opinion - I'd rather take more than what I think I need, so as to give the body what it needs and my pee can release the rest. Good luck to you.

Synthetic folic acid has a higher bioavailability than the natural form. But it must go through a four step conversion process to be equal. So it's not just absorption but also having the right form that matters. I doubt that with 1667% of RDA, the absorption would be too low to get at least the 50%. Have you tried google?
