Primary Outcome Measures:

The primary measure to determine the effect of the treatment will be reduced levels of Homocysteine in subjects with B12 deficiency combined with C677T mutation in the MTHFR gene. [ Time Frame: The key measure would be measured upon enrollment and 6 weeks afterwards, upon completion of treatment based on 1mg Vitamin B12 sublinual and 5 mg Folic Acid per day. ] [ Designated as safety issue: No ]

Estimated Enrollment:	300
Study Start Date:	July 2008
Estimated Study Completion Date:	July 2010
Estimated Primary Completion Date:	July 2010 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
B: No Intervention The control group, marked B, gets only B12 vitamin 1mg/day treatment to comply with ethics regulations seeing as they do suffer from B12 deficiency but they do not get the combined B12+Folic acid treatment as do the trial subjects	Dietary Supplement: B12 Vitamin Control group would only receive daily treatment of 1mg Vitamin B12 sublingual seeing as they suffer from Vitamin B12 deficiency
A: Experimental The trial group which receives daily treatment of 1mg Vitamin B12 (sublingual tablets) combined with 5Mg Folic acid (tablets)	Dietary Supplement: Vitamin B12 + Folic Acid Trial group would get daily treatment of 1mg Vitamin B12 combined with 5mg Folic Acid
