Swanson Folate 5-Methyltetrahydrofolic Acid – High Potency, Bioactive Form 800 mcg DFE 30 Veg Caps (2 Pack)

What Is 5-Methyltetrahydrofolate (5-MTHF)?

For many of us, maintaining adequate folate levels is a cornerstone of good health—especially for those planning a pregnancy or keeping an eye on cardiovascular wellness. But not all folate supplements perform the same. Swanson’s high-potency bioactive folate delivers 800 mcg DFE of 5-methyltetrahydrofolate (5-MTHF), the biologically active form of vitamin B9. Unlike synthetic folic acid, which requires conversion by the liver, 5-MTHF is ready for your body to undertake immediately. This makes it an excellent option for individuals with MTHFR gene variations that may hinder folate metabolism. Each serving comes in a convenient vegetarian capsule.

Folic Acid vs. 5-MTHF: What's the Difference?

Folic acid is the synthetic version of vitamin B9 found in many supplements and fortified foods. It must be converted by the MTHFR enzyme into the active form, 5-MTHF. However, up to 60% of the population carry genetic variants that reduce this conversion efficiency. 5-Methyltetrahydrofolate (5-MTHF) skips that step, offering direct usability regardless of your genetics. This makes it a superior choice for targeted support, especially for those with known MTHFR mutations.

Key Benefits of Bioactive Folate

• Supports normal red blood cell formation: Folate contributes to normal red blood cell production, helping maintain healthy oxygen transport throughout the body.
• Promotes heart health: Adequate folate intake contributes to normal homocysteine metabolism, which is important for cardiovascular wellbeing.
• Essential for prenatal health: Folate contributes to normal maternal tissue growth during pregnancy. Low maternal folate status is a risk factor for neural tube defects in the developing foetus.
• Supports DNA synthesis and cell division: Folate is required for the creation and repair of DNA, making it essential for rapidly dividing cells during pregnancy and growth.

Who Should Consider Taking Folate?

This bioactive folate supplement may be particularly useful for:

• Women planning pregnancy or during pregnancy: Adequate folate is critical before and during early pregnancy to support foetal development.
• Individuals with MTHFR gene variants: Those with common MTHFR mutations may benefit from 5-MTHF, as it bypasses the conversion step.
• Older adults: Ageing can reduce the body's ability to convert folic acid, making active folate a smart choice.
• Anyone with a diet low in folate-rich foods: Such as leafy greens, legumes, and fortified grains.

How to Choose a Quality Folate Supplement

When selecting a folate supplement, consider the following:

• Form: 5-MTHF (as calcium salt) is more bioavailable than folic acid for most people.
• Dosage: Look for a dose that matches your needs—this product provides 800 mcg DFE per serving.
• Third-party testing: Swanson follows Good Manufacturing Practice (GMP) and their products are tested for purity and potency.
• Vegetarian/vegan: These capsules are vegetarian-friendly.

How Much Folate Should You Take?

The Reference Nutrient Intake (RNI) for folate in the UK is 200 mcg per day for adults, 300 mcg during pregnancy, and 260 mcg while breastfeeding. This product provides 800 mcg DFE per serving (one capsule), which is a high-potency dose. The safe upper level from supplements is 1,000 mcg DFE per day. Always consult your GP or health care provider to determine the right dose for your needs.

Potential Side Effects and Precautions

Folate is generally well tolerated. High doses (above 1,000 mcg) may mask a vitamin B12 deficiency, especially in older adults. If you have a history of B12 deficiency or pernicious anaemia, consult your health care provider before taking high-dose folate. Always undertake supplements as directed and do not exceed recommended dosages. If you experience any adverse effects, discontinue undertake and speak to your GP.
