Return to table 3 footnote 12 referrer Table 3 footnote 13 The UL for folate applies only to synthetic forms obtained from supplements, fortified foods, or a combination of the two. The UL values are expressed as micrograms of folic acid, not micrograms of DFEs. Return to table 3 footnote 13 referrer Table 3 footnote 14 Due to lack of suitable data, ULs could not be established for vitamin B12, pantothenic acid or biotin. This does not mean that there is no potential for adverse effects resulting from high intakes. Return to table 3 footnote 14 referrer Table 3 footnote 15 Although AIs have been set for choline, there are few data to assess whether a dietary supply of choline is needed at all stages of the life cycle, and it may be that the choline requirement can be met by endogenous synthesis at some of these stages. Return to table 3 footnote 15 referrer Table 3 footnote d In view of evidence linking the use of supplements containing folic acid before conception and during early pregnancy with reduced risk of neural tube defects in the fetus, it is recommended that all women capable of becoming pregnant consume 400 μg of folic acid every day, in addition to intake of food folate from a varied diet. Return to table 3 footnote d referrer Table 3 footnote e It is assumed that women will continue consuming 400 μg folic acid from supplements until their pregnancy is confirmed and they enter prenatal care. The critical time for formation of the neural tube is within four weeks after conception. Return to table 3 footnote e referrer Table 3 footnote f Because 10 to 30 percent of older people may malabsorb food-bound vitamin B12, it is advisable for those older than 50 years to meet the RDA mainly by consuming foods fortified with vitamin B12 or a supplement containing vitamin B12.
