Vitamins, especialls B vitamins are one of my favourite subjects.
B vitamins cannot be considered as a whole.
Each one is required itself, they just need
each other's peresence to work best.

Troy is right, but you'll have to eat real *plenty* of meat
and plenty of organ meats too to get sufficient some.
Liver is a very good vitamin A source, and a reasonable good source
of B vitamins. The amounts needed (especially of the potentially
dangerous liver) are realy enormous - at least in my point of view.
Look at the data below, I compiled.

You seem to consider a high meat diet as "the" paleo diet.
But meats are generally *no* rich source of B-vitamins (except B2).
Liver is the only meat of higher contents because liver is the (animal)
bodie's storage organ for some vitamins.
But its not a good source of choice, because it's too high in vitamin A
(as repeatedly discussed and as Richard mentiones).
How much dried liver (from how much fresh liver) would you
give to your kid *every day* ? For enough folate, niacin or thiamin?

Try *200* grams of liver.
 vitA (IU)   71358    5000 1427.16%
 vitC (mg)      46      60   76.67%
 Thia (mg)     0.4     1.5   26.67%
 Ribo (mg)     8.2     1.7  482.35%
  Nia (mg)   21.44      19  112.84%
 Chol (mg)     778     300  259.33%
 Folate       about         200.00%
 B6           about          100%
Even if the vitamin A wasn't toxic (14-fold!) it was just enough
for the niacin (112%) and C(76%) - b2 as expected plenty.
Even then the Thiamin is rather low(25%).

How much vitamin-A overdose would you risk?

Now try that with normal beef.
Who's child eats a whole pound of beef?

Here are the results of the one pound for a kid (10 y o).
   Nutri     Total    Rec.   %Rec.
-----------+--------+------+------
   Pro (g)  135.62      28  484.36%
 Iron (mg)   13.61      10   136.1%
   Na (mg)  299.37    2000   14.97%
 Phos (mg) 1047.79     800  130.97%
 vitA (IU)       0    3500       0%
 vitC (mg)       0      45       0%
 Thia (mg)    0.41       1      41%
 Ribo (mg)    1.09     1.2   90.83%
  Nia (mg)   18.14      13  139.54%
Folate is about  15.7  160    10%
B6     is about   .9    1.8   50%
Even in this amount some B vitamins may be plenty,
others are still low.
The challenge is to find adequate food items providing the rest.

Todd, how much meat and liver would you give to the kid?
200 grams of liver *every day*?
1 pound of beef *every day*?

Say, Richard, do you have the possibility to sort food items
by ingredient (e.g. niacin?). And to exclude unwanted items
- unpaleo unnatural or composite items?
That would be handy looking after the *natural* providers of essentials.
I *can* sort by ingredient (per weight only).
But niacin isn't included.
On the net I never found an ingredient searcher except
http://www.mymenus.com/nutr13.htm    but they sort their own menues
only. Unpaleo. Unable to distinguish the sources.
I include such a hardcopy just for your "inspiration" ;-)
