Folate (vitamin B-9) is essential in producing red blood cells and DNA, the genetic material in our cells. Folate is especially essential during early gestation to lower birth defect risks in both brain and spine regions.

Folate is found naturally in many foods such as leafy greens, beans, peas and nuts, while it’s also added as an additive in foods and supplements as folic acid – this form being more absorbable than what could be found naturally in food sources.

Integration

Folate (vitamin B9) is an essential water-soluble vitamin essential for cell development and DNA synthesis, naturally found in many vegetables, legumes and fruits as well as synthetically produced as folic acid for prenatal vitamins that reduce risk of neural tube defects in newborns. Because folate plays such a key role in many metabolic pathways and methylation reactions a poor folate status increases risks of cancer, cardiovascular disease and cognitive dysfunction among others.

Folate is not stored by our bodies, making regular intake essential to maintaining adequate levels in our blood. In the US, leafy green vegetables, beans, nuts, eggs and meat are the primary dietary sources of folate; due to its low bioavailability, many are failing to consume the recommended daily amount. Folate deficiency may also result from digestive system diseases like Crohn’s or ulcerative colitis as well as medication such as anti-seizure medications or antibiotics causing depletion.

To address the need for accurate measurements of circulating folates, various biomarkers have been created. While not all selected biomarkers have proven sensitive indicators of diet intake or clinical outcomes, some have potential future use in monitoring changes or clinical outcomes. The Folate Expert Panel advises evaluating each biomarker carefully for its sensitivity and specificity in order to make an informed decision for future research or clinical applications.

Serum and red blood cell (RBC) folate levels are among the most frequently monitored folate biomarkers. According to our panelists, both measures are useful and necessary in assessing individual folate vitamer levels; additionally they may also be used to monitor how food fortification impacts public health.

Both methods of measurement require careful sample collection and preparation, in addition to careful consideration of folic acid absorption, metabolism, and clearance rates. Serum folate may be susceptible to interconversion into reduced forms and oxidative degradation that could have an impactful influence on results interpretation; as per this panel’s assessment this may contribute to some of the higher variability observed with serum than RBC folate levels.

Methylation Support

Folate and B vitamins are necessary for the methylation process to occur properly; it’s a chemical process which adds methyl groups to certain chemicals so they can lower inflammation, produce neurotransmitters and protect our DNA. Optimized methylation is key to overall health; otherwise it could result in several different health issues.

Folate’s main role in methylation is helping convert homocysteine to methionine for use as the universal methyl donor, S-adenosylmethionine (SAMe). SAMe is required for all our methylation processes including DNA methylation and gene silencing processes.

Folate is an essential water-soluble vitamin for red blood cell production and amino acid metabolism in the liver. It’s found in foods like vegetables, legumes, eggs and fortified grain products – as well as being included in prenatal multivitamins to lower birth defect risks.

Genetic variations in the MTHFR gene can impact how efficiently the body uses folate. People who possess these gene variants may require higher doses of 5-methyltetrahydrofolate (5-MTHF), and may benefit from taking methylated B-complex supplements as part of their regimen.

Diets high in nutrients that support our methylation needs such as B vitamins, choline and methionine can be especially helpful. Alcohol and coffee may deplete methyl donors from our bodies.

Based on your unique health history, consulting a functional medicine practitioner to conduct a comprehensive panel can be highly beneficial in identifying any deficiencies or imbalances with your methylation status and identify any deficiencies or imbalances. This panel may include blood, urine and hair tests as well as more extensive options such as the Nutrient Genomics test from Spectralytics; this test measures all B vitamin levels along with other key markers like methylation status, folate levels, estrogen production levels and thyroid functioning levels to assist your nutritional strategy planning process.

Personalized Supplementation

Folate, also known as vitamin B9, is an essential water-soluble vitamin essential for optimal cell development and function. Its effects can be seen in red blood cell production, amino acid metabolism and DNA synthesis – as well as helping prevent neural tube defects during early gestation. Naturally occurring folate can be found in leafy green vegetables, beans and peas, eggs and citrus fruits while its synthetic form folic acid can be found in fortified grain products with recommended daily dosage levels determined by its effectiveness in mitigating birth defect risks.

Companies offer customized supplements tailored specifically for each person based on their biochemistry. Their personalized supplementation strategies typically begin with an assessment that asks about age, gender, health goals and diet before providing a unique set of vitamins designed to optimize individual biology. They even offer subscription models whereby they’ll ship the right combination to you on a monthly basis!

Elo is one of these companies and provides an innovative service by using in-home blood testing and data from wearable devices to determine your personalized formula. They recommend repeat testing every three to six months so they can keep an eye on biomarkers and adjust nutrition needs as necessary.

Notably, personalized supplement programs should not replace comprehensive nutrition analysis from a registered dietitian nutritionist. While such companies may try to help, their approach does not address all aspects of health and wellbeing in a holistic way.

Folate is an essential nutrient for everyone, but especially during periods of rapid cell division such as during infancy and pregnancy. A deficiency can impair DNA synthesis and has been linked to increased risks of cardiovascular disease through homocysteine concentrations. Supplementing with folic acid has shown promising results for decreasing homocysteine concentrations; however, only when taken in combination with B12 and B6.

Monitoring Clinical Outcomes

Folate is an essential water-soluble B-complex vitamin needed for DNA synthesis, red blood cell production, amino acid metabolism and other biological functions. Folate has long been used by pregnant women to prevent megaloblastic anemia as well as NTD risk reduction; since 1998 the U.S. Food and Drug Administration requires that synthetic folate (folic acid) be added to enriched grain products targeted toward women of reproductive age in order to lower NTD risks.

Low dietary intake is one of the leading causes of clinical folate deficiency in both developed and developing countries, particularly for those in lower socioeconomic status groups that typically do not consume enough folate to achieve optimal biomarker levels associated with human development and fetal growth.

Foods high in folate may not always be sufficient to counteract genetic predisposition to metabolic impairment. A common genetic variant that reduces one-carbon metabolism leads to an accumulation of homocysteine in the blood, an indicator of cardiovascular disease as well as cell dysfunction that can result in endothelial damage, glucose intolerance, insulin resistance and ultimately obesity.

Folate and cobalamin are widely available in most diets, yet are susceptible to interconversion and oxidative degradation, making measurement of serum/RBC folate challenging. Folate vitamers may be measured using various methods; several are reviewed in Supplemental Table 1. In this section we summarize their use, advantages, disadvantages and analytical considerations with specific details provided for serum and RBC folate and plasma homocysteine biomarkers in subsequent sections.

Numerous randomized controlled trials have demonstrated that supplementing with methylated B vitamins (i.e., folic acid plus vitamins B6 and B12) reduces total homocysteine in blood by supplementation. While these results have proven positive, some concerns still exist as to its efficacy when considering heart disease risk or mortality risk – including potential inadequate responses to high dose supplementation approaches and lack of long-term safety data.
