ClinicalTrials.gov Identifier:	NCT00730574

Purpose

The purpose of this study is to determine the commonness of the C677T mutation in the MTHFR gene in subjects with B12 deficiency. Also, we'd like to investigate the effect of B12 deficiency combined with the C677T mutation on endothelial function.

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
No Intervention: B 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 Other Name: Vitamin B12, 1 mg, by Solgar - sublingual tablets
Experimental: A The trial group which receives daily treatment of 1mg Vitamin B12 (sublingual tablets) combined with 5 mg Folic acid (tablets)	Dietary Supplement: Vitamin B12 + Folic Acid Trial group would get daily treatment of 1 mg Vitamin B12 combined with 5 mg Folic Acid Other Names: Vitamin B12, 1 mg, by Solgar Folic acid, 5 mg, by Rakah
