Research – Excess Folate, Vitamin K and Bone Density, Calcium Absorption

1. Some observations in animal and human studies demonstrate that an overly
abundant intake of folate among those who harbor existing foci of neoplasia
(tumors) might instead produce a paradoxical promotion of tumorigenesis (tumor
growth). Source: Biofactors. 2011 Jul;37(4):253-60. doi: 10.1002/biof.174.
2. Better vitamin K status was associated with increased bone mineral content
in young girls (age 3-16).  Source: Br J Nutr. 2007 Apr;97(4):661-6
3. Calcium is better absorbed from calcium citrate than calcium carbonate when
these salts are taken on an empty stomach in most women. Source: J Am Coll
Nutr. 1990 Dec;9(6):583-7
