Methylated B Complex Vitamins, Made in the USA, 2-Month Supply, Methyl B Complete with Quatrefolic 5-MTHF Folate, B12 Methylcobalamin, TMG Trimethylglycine, Methylfolate, Pharm Grade, 60 Count

Key Ingredients and Their Active Forms

This supplement, produced by Pure Therapro Rx, features a carefully selected blend of methylated B vitamins and trimethylglycine (TMG). The key difference from standard B-complexes is the uses of bioactive forms that the body can utilise directly:

• Folate as Quatrefolic (5-MTHF): This patented, highly bio-available form of folate bypasses the MTHFR conversion step, making it ideal for those with genetic variations. Each capsule supplies 3,400 mcg (1700% of the Nutrient Reference Value).
• Vitamin B12 (Methylcobalamin and Adenosylcobalamin): Rather than synthetic cyanocobalamin, this formula provides the two coenzyme forms directly usable by the body. The 1,000 mcg per capsule supports nerve health and energy production.
• Vitamin B6: Involved in amino acid metabolism and neurotransmitter synthesis, 15 mg per capsule.
• Riboflavin (Vitamin B2): Essential for energy metabolism and activation of other B vitamins, 25 mg per capsule.
• TMG (Trimethylglycine): Also known as betaine, this methyl donor supports homocysteine regulation. Each capsule contains 650 mg.

These ingredients are selected for purity and potency, with no fillers, flow agents, or artificial additives. The product is manufactured in an NSF-certified facility in the USA, adhering to cGMP standards.

Benefits of a Methylated B-Complex

Taking a methylated B-complex may offer several benefits grounded in nutritional science:

• Energy metabolism: B vitamins assist in converting food into energy, potentially reducing fatigue.
• Nervous system function: Vitamin B12 and B6 contribute to normal nerve transmission and myelin sheath formation.
• Homocysteine regulation: Folate, B12, B6, and TMG work together to maintain healthy homocysteine levels, which is important for cardiovascular and brain health.
• DNA synthesis and repair: Folate plays a centre role in cell creation, including red blood cells.
• Red blood cell formation: B12 and folate are essential for proper red blood cell development.

These benefits arise from core physiological processes and are supported by decades of research.

How to Take This B-Complex

The recommended serving is one capsule daily, taken with food to improve absorption and minimise any mild digestive upset. Since B vitamins are water-soluble, excess amounts are generally excreted, whilst you should discuss high-dose supplementation with a health care professional.

This product can be combined with other supplements, but avoid taking it alongside high-dose folic acid or non-methylated B12, as this may interfere with the activity of the methylated forms.

How to Choose the Right B-Complex Supplement

When selecting a B-complex, consider the following factors:

• Methylated forms: If you have an MTHFR mutation or seek optimal absorption, look for folate as methylfolate (5-MTHF) and B12 as methylcobalamin – not folic acid or cyanocobalamin.
• Purity: Avoid supplements with unnecessary fillers, binders, or artificial ingredients. This product is free from gluten, soya, corn, yeast, dairy, nuts, and animal products.
• Manufacturing standards: Choose brands that follow cGMP guidelines and are third-party tested. Pure Therapro Rx is made in an NSF-certified facility in the USA.
• Dosage: Ensure the amounts align with your needs. This formula provides a two-month supply at one capsule per day.

Note that this is not a full-spectrum B-complex – it focuses on the key methyl donors. If you require other B vitamins (B1, B3, B5, B7), consider supplementing separately or selecting a broader formula.

What Is B-Complex and Why Is Methylation Important?

B vitamins are a group of eight essential nutrients that work synergistically to support energy production and nervous system health. One of their most crucial roles is in methylation, a biochemical process affecting DNA synthesis, neurotransmitter production, detoxification, and homocysteine regulation. For individuals with MTHFR gene variants, the conversion of synthetic folic acid into active 5-MTHF may be impaired, making methylated B vitamins a valuable option for supporting efficient methylation.

This formula targets the key methyl donors: folate (as Quatrefolic 5-MTHF), vitamin B12 (as methylcobalamin and adenosylcobalamin), vitamin B6, riboflavin, and TMG. Together, they provide targeted support for methylation pathways without requiring conversion steps.

Side Effects and Interactions

B vitamins are generally safe, but some people may experience:

• Bright yellow urine: Caused by riboflavin (B2) and is harmless.
• Mild nausea or digestive upset: Taking with food can help.
• Insomnia or nervousness: Rarely, high-dose B12 or B6 may cause overstimulation.

Potential interactions: TMG may affect blood pressure in some individuals; those on anticoagulants or antiepileptic medications should consult a doctor before uses.

Frequently Asked Questions

Who should take a methylated B-complex?

Anyone looking to support methylation pathways may benefit, especially individuals with MTHFR gene variants, those over 50 (as B12 absorption declines), or those with dietary restrictions limiting B vitamin intake.

Can I take this if I have a full B-complex?

This formula provides only the methylated B vitamins and TMG. If you need other B vitamins, check the labels to avoid duplicating high doses. You may alternate days or take a separate full B-complex on different days.

Is this product vegan?

Yes, the capsules are plant-based and the product contains no animal-derived ingredients.

How long does one bottle last?

With 60 capsules and a serving of one per day, this bottle provides a two-month supply.
