In most cases, serum folate testing alone is sufficient for assessment of folate status, but if there is strong clinical suspicion of folate deficiency and the serum folate level is normal and cobalamin deficiency has been ruled out, the red blood cell (RBC) folate level may be measured. In another clinical trial in older adults (mean age 74.1 years) with elevated homocysteine levels, supplementation with 400 mcg folic acid plus 500 mcg vitamin B12 and 600 IU vitamin D3 for 2 years lowered homocysteine levels but did not affect cognitive performance compared with 600 IU vitamin D3 alone [107].
