Vitamin B9 (Folate): The Unsung Hero of Health + 20 Delicious Foods Packed with It

What Is Vitamin B9 (Folate)?

Vitamin B9 is a water-soluble B-vitamin that exists in two main forms:

• Folate – naturally occurring in whole foods
• Folic acid – synthetic form found in supplements and fortified foods

Folate is crucial for:

•  DNA and RNA synthesis
•  Red blood cell formation
•  Preventing birth defects during pregnancy
•  Brain function and mental clarity
•  Energy production

Because your body doesn’t store much B9, you need to get it daily through food or supplements.

 Symptoms of Folate Deficiency

Folate deficiency is more common than most people realize, especially among:

• Pregnant women
• People with digestive disorders (like celiac or IBS)
• Heavy alcohol users
• Those on certain medications (e.g., methotrexate, birth control)

Common signs include:

• Fatigue or weakness
• Poor concentration or memory issues
• Irritability or depression
• Pale skin
• Mouth sores or a swollen tongue
• Shortness of breath
• Birth defects (neural tube issues) in unborn babies

If you suspect a deficiency, speak to your healthcare provider and consider a blood test.

Cooking Tips to Maximize Folate

Since folate is water-soluble and heat-sensitive, it can be lost during cooking.

Here’s how to preserve it:

• Steam instead of boiling veggies
• Cook with minimal water and avoid overcooking
• Use raw or lightly sautéed greens in salads and wraps
• Save and reuse cooking liquids from beans or greens
• Store produce properly to prevent folate degradation
