Douglas Laboratories Metilfolato L-5-MTHF 1000 mcg Metafolin - 60 Comprimidos

What is L-5-MTHF Methylfolate?

Methylfolate, also known as L-5-methyltetrahydrofolate (L-5-MTHF), is the biologically active form of folate (vitamin B9). Unlike synthetic folic acid, methylfolate does not require conversion in the liver to be used by the body, making it especially useful for individuals with certain genetic variations (such as the MTHFR mutation). Douglas Laboratories' supplement provides 1,000 mcg of Metafolin®, the patented, natural form of L-5-MTHF, in easy-to-take tablets.

EFSA-Backed Benefits

Folate (vitamin B9) has approved health claims by the European Food Safety Authority (EFSA). These include:

• Folate contributes to maternal tissue growth during pregnancy.
• Folate contributes to normal amino acid synthesis.
• Folate contributes to normal psychological function.
• Folate contributes to normal blood formation.
• Folate contributes to normal homocysteine metabolism.

Additionally, folate plays a role in the process of cell division and helps reduce tiredness and fatigue.

Key Ingredients and Their Functions

Metafolin® (L-5-MTHF): This is the form of folate naturally present in foods and the one directly used by the body. Being bioactive, it bypasses the need for enzymatic conversion, resulting in optimal absorption even in individuals with reduced folic acid metabolism. Methylfolate is essential for:

• DNA and RNA synthesis.
• Homocysteine regulation, a cardiovascular risk factor.
• Fetal nervous system development during pregnancy.
• Red blood cell production and oxygen transport.

Douglas Laboratories uses pharmaceutical-grade, non-GMO Metafolin®, manufactured under strict GMP standards to ensure purity and potency.

How to Choose the Best Folate Supplement?

When choosing a folate supplement, it's important to consider the form and dosage. Methylfolate (L-5-MTHF) is the preferred option for most people, especially during pregnancy or lactation, as it is directly usable by the body. A dose of 1,000 mcg (1 mg) is common to cover increased needs during pregnancy, although the exact amount should be determined by a healthcare professional. Look for brands with good manufacturing practices, such as Douglas Laboratories, which offer traceable products free of unnecessary allergens.

When and How to Take It?

It is recommended to take one tablet daily, preferably with a meal to facilitate absorption. Women planning pregnancy should start supplementation at least one month before conception and continue during the r trimester, according to medical recommendations. Always consult your doctor or pharmacist before starting any supplement, especially if you are pregnant, breastfeeding, or have any medical condition.

Possible Side Effects and Precautions

Methylfolate is generally well-tolerated. At high doses (over 1 mg daily), some individuals may experience mild gastrointestinal discomfort or allergic reactions. No significant drug interactions have been reported, but it is always advisable to inform your doctor about all supplements you are taking. Food supplements should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended daily dose. Keep out of reach of children.

Frequently Asked Questions

What is the difference between folic acid and methylfolate?

Folic acid is the synthetic form of folate, which must be converted to methylfolate in the liver by an enzyme (MTHFR). Many people have genetic variations that reduce this conversion, making methylfolate a more direct and effective option.

Can I take this supplement if I am not pregnant?

Yes, methylfolate is beneficial for anyone who wants to support cardiovascular health, red blood cell production, and overall well-being. Always consult a healthcare professional.

Is it safe for vegans?

This product does not contain animal-derived ingredients, but it is recommended to check the label to confirm. Douglas Laboratories offers non-GMO options suitable for special diets.
