Determining the right amount of folate is crucial for maintaining optimal health. The established upper limit for folate intake from supplements and fortified foods is 1,000 mcg per day for adults. Exceeding this can mask vitamin B12 deficiency symptoms, potentially leading to nerve damage, and might increase cancer risks. Folate needs vary based on age, sex, and health conditions:

  • Infants to Adults: 65-400 mcg DFE
  • Pregnant and Breastfeeding Women: 500-600 mcg DFE
  • Alcohol Use Disorder: Higher due to poor absorption
  • Absorption Disorders (e.g., celiac disease): Increased need
  • MTHFR Gene Variant: Prefer methylfolate over folic acid

What Does Folate Do?

Folate, also known as vitamin B9, plays a crucial role in DNA synthesis and cellular division. These processes are essential for the body’s growth and repair, making folate indispensable for maintaining healthy tissues and organs. Folate also contributes to the production of red blood cells, preventing anemia, and supporting overall bodily functions.

Benefits of adequate folate consumption: 

  • Mental Health: May reduce the risk of depression by enhancing brain function and supporting cognitive function.
  • Pregnancy: Prevents birth defects, particularly neural tube defects, and ensures proper fetal development.
  • General Bodily Functions: Consuming natural sources of folate supports cardiovascular health by lowering homocysteine levels

How Much Folate Do You Need Daily?

The daily recommended folate intake varies based on age, sex, and pregnancy status. Infants need 65-80 micrograms (mcg) of dietary folate equivalents (DFE), while children’s needs increase from 150 mcg DFE for ages 1-3 years to 300 mcg DFE for ages 9-13 years. Teens and adults should consume 400 mcg DFE. Pregnant teens and women require a higher folate intake of 600 mcg DFE while breastfeeding women need 500 mcg DFE.

To calculate your appropriate folate intake, it’s advisable to consult a doctor who can help determine the suitable dosage for your specific health condition and ensure you are meeting your body’s requirements for optimal health.

Children (1-3 years) 150
Children (4-8 years) 200
Children (9-13 years) 300
Teens (14-18 years) 400
Adults (19+ years) 400
Pregnant Teens/Women 600
Breastfeeding Teens/Women 500

 

Dose Before and During Early Pregnancy

Increased folate needs before and during early pregnancy are essential due to folate’s critical role in preventing neural tube defects. Folic acid is recommended to ensure adequate folate levels, minimizing the risk of conditions like spina bifida.

Dosage recommendations: 

  • Standard recommendation: 400 micrograms (mcg) of folic acid daily to ensure an optimal folate dosage from before pregnancy until 12 weeks into pregnancy.
  • Higher risk cases: 5 milligrams (mg) daily for those with a higher risk of neural tube defects, such as a family history, diabetes, or use of anti-epilepsy medications.

To ensure you’re getting enough folate before and during pregnancy, consider incorporating folate-rich foods and supplements. For more tips on boosting your folate levels, check out our guide on how to increase folate.

Dose for Treating Folate Deficiency Anaemia

Folate deficiency anemia is treated by adjusting the dosage of folic acid to replenish the body’s folate stores and address the symptoms of anemia. The typical approach involves administering higher doses of folic acid initially to rapidly correct the deficiency, followed by a maintenance dose to prevent recurrence.

Typical dosages:

  • Adults and Children Over 1 Year Old: 5 mg (5000 micrograms) of folic acid daily. 
  • Infants Under 12 Months Old: The dose is calculated based on the child’s weight.
  • Maintenance Dose: Generally 5 mg every 1 to 7 days, adjusted as needed.

These dosages ensure patients receive the acceptable daily folate amount necessary to manage their condition, supported by evidence from clinical guidelines. 

To accurately diagnose and treat folate deficiency anemia, it’s crucial to monitor your folate levels regularly. Consider taking a folate test to ensure you’re maintaining adequate folate levels.

Dose If You’re Taking Methotrexate

Methotrexate, a common treatment for rheumatoid arthritis and other conditions, blocks folate, necessitating increased folate intake to mitigate side effects. Research has shown that folic acid supplementation helps regulate folate levels, reducing the drug’s side effects such as gastrointestinal discomfort and hepatotoxicity.

Dosage recommendations: 

  • Standard dose: 5 mg of folic acid once weekly, taken on a different day than methotrexate.
  • Alternative dose: 1 mg to 5 mg of folic acid daily except on the day methotrexate is taken.
