Diminished gastric acid secretion associated with atrophic gastritis, gastric surgery, and other conditions can also reduce folate absorption [4]. Medical experts agree that the normal range of folic acid in the blood is between 2.7 and 17.0 nanogram/milliliter. Limited research suggests that single doses of 300 mcg or 400 mcg folic acid (a common amount in folic acid-containing supplements or servings of fortified foods, such as breakfast cereals) result in detectable serum levels of unmetabolized folic acid, whereas doses of 100 mcg or 200 mcg do not [162,163].

N Engl J Med. Folate deficiency in rats induces DNA strand breaks and hypomethylation within the p53 tumor suppressor gene. Scientists hypothesize that elevated homocysteine levels might have a negative effect on the brain via numerous mechanisms, including cerebrovascular ischemia leading to neuronal cell death, activation of tau kinases leading to tangle deposition, and inhibition of methylation reactions [103]. The mixed findings from clinical trials, combined with evidence from laboratory and animal studies indicating that high folate status promotes tumor progression, suggest that folate might play dual roles in cancer risk, depending on the dosage and timing of the exposure.

Folate and other B vitamins are involved in homocysteine metabolism, and researchers have hypothesized that these micronutrients reduce cardiovascular disease risk by lowering homocysteine levels [1,85]. 0000251486 00000 n Additional serum testing with homocysteine and methylmalonic acid (MMA) determinationsmay help distinguish between vitamin B12 and folate deficiency states. Some noted, however, that when researchers took baseline homocysteine and B-vitamin status into account, B-vitamin supplementation slowed cognitive decline in individuals at high risk of cognitive decline [103,104]. About 25% of Hispanics, 10% of Caucasians and Asians, and 1% of African Americans are homozygous for the 677C>T MTHFR polymorphism [27].

A doctor may conduct a folic acid test if one shows deficiency signs of folic acid. Tietz Textbook of Clinical Chemistry and Molecular Diagnostics. With this condition, red blood cells are larger than normal. However, many confounding factors, such as transfused red cells, can make this unreliable as a test for folate deficiency states. Compared with placebo, treatment with B vitamins significantly decreased homocysteine levels but did not reduce the risk of death from cardiovascular causes or myocardial infarction. The labels must list folate content in mcg DFE per serving and if folic acid is added to the product, they must also list the amount of folic acid in mcg in parentheses. [QxMD MEDLINE Link]. The authors of a systematic review and meta-analysis of three trials of 5-MTHF (<15,000 mcg/day in one trial, and 15,000 mcg/day in two trials) in combination with fluoxetine or other antidepressants, concluded that 15,000 mcg/day 5-MTHF might be an effective adjunct to SSRI therapy in patients with major depressive disorder, although they noted that this conclusion was based on low-quality evidence [127].
