Wind_Rider,
Freeda makes a B complex in various strengths that has no starch. I use the Quin B Strong B-25, which includes folate and B-12, the most likely B vitamins to be deficient in malabsorbtion in the intestines. The label states that it is free of gluten, lactose, artificial color, artificial flavor (that's for sure), animal derivatives, sugar, STARCH, gelatin, and yeast. In addition to the B vitamins, it also contains cellulose, calcium chloride, calcium stearate, and silica. You can order online at their web site:

You can get 100 tablets for about $7, which seems reasonable to me. This company is widely recommended to people on the SCD, and they are on a reduced starch diet. I have never heard of anyone on the SCD having an intestinal problem with the Freeda vitamins, although some have had urinary tract irritation from the B complex vitamins. Hope this helps your search.
