Designs for Health Methylated Vitamin B Complex - 120 Capsules

Key Ingredients & Forms

Discover Designs Health Methylated — What sets this B-complex apart is its intelligent use of active, bioavailable nutrients that your body can utilise right away. Whether you have an MTHFR variant or simply want the most effective support, this formula delivers a potent blend of all eight B vitamins in their coenzymated forms, plus extra methyl donors like TMG and choline. Here’s what you get in each two-capsule serve:

• Vitamin B1 (Thiamine) – 25 mg as thiamine HCl, supporting carbohydrate metabolism and nerve function.
• Vitamin B2 (Riboflavin) – 25 mg as riboflavin, essential for energy production and antioxidant protection.
• Vitamin B3 (Niacin) – 25 mg as niacinamide, a flush-free form that supports skin health and cholesterol balance.
• Vitamin B5 (Pantothenic Acid) – 50 mg as d-calcium pantothenate, critical for hormone and fatty acid synthesis.
• Vitamin B6 – 25 mg as pyridoxal-5-phosphate (P-5-P), the active coenzyme form that bypasses liver conversion.
• Biotin – 500 mcg, supporting hair, skin, nails, and macronutrient metabolism.
• Folate – 800 mcg DFE from Quatrefolic® (6S-5-methyltetrahydrofolate), a highly stable and absorbable methylated form—no synthetic folic acid.
• Vitamin B12 – 500 mcg as methylcobalamin, the active form that supports nerve health and methylation.
• Plus TMG (betaine) and choline (as choline bitartrate), both serving as methyl donors to support homocysteine metabolism.

The Quatrefolic® folate is particularly noteworthy—it is a glucosamine salt of (6S)-5-methyltetrahydrofolate, which demonstrates superior solubility and bioavailability compared to folic acid, especially for individuals with MTHFR polymorphisms.

Benefits of B-Complex

B vitamins are fundamental to turning food into energy. This methylated B complex supports sustained energy throughout the day, helping you combat occasional fatigue and brain fog.* The inclusion of methylcobalamin (B12) and methylfolate (B9) also contributes to healthy homocysteine levels, which is important for heart and blood vessel health.*

Beyond energy, these nutrients are critical for nervous system function. B6, B12, and folate are involved in the synthesis of neurotransmitters like serotonin and dopamine, which influence mood and cognitive performance.* Many users report improved mental clarity and a more balanced mood when taking a high-quality methylated B-complex. Additionally, biotin and pantothenic acid support healthy hair, skin, and nails, while niacin promotes proper circulation and cholesterol metabolism.

Research continues to highlight the role of B vitamins in maintaining normal homocysteine metabolism—a key factor in cardiovascular wellbeing. The methylated forms in this supplement are especially effective at reducing homocysteine levels, thereby supporting long-term heart health.*

How to Choose the Right B-Complex

When selecting a B-complex, consider your individual needs and biochemistry. This formula is ideal for those seeking:

• Methylated forms: Essential for up to 40% of the population with MTHFR variants who cannot efficiently convert folic acid or cyanocobalamin.
• High potency: Provides meaningful doses of each B vitamin—many at 100% or more of the Recommended Dietary Intake—to address deficiencies or increased needs.
• Allergen-friendly: Vegan, Non-GM, gluten free, dairy-free, and soy-free. No artificial additives.
• Practitioner-trusted: Designs for Health is a leading brand recommended by functional medicine professionals, ensuring quality and purity.

If you have a known MTHFR mutation, are over 50, follow a vegetarian or vegan diet, or experience chronic stress, a methylated B-complex like this one may offer superior support compared to standard synthetic versions. Always consult a healthcare professional before starting a new supplement regimen.

What is B-Complex?

B-Complex refers to a group of eight essential B vitamins that work synergistically to support numerous physiological processes. This particular formula from Designs for Health delivers a potent blend of all eight B vitamins, plus additional co-factors like trimethylglycine (TMG) and choline, to promote optimal methylation and nutrient utilisation. Unlike many standard B-complex supplements, this formula prioritises coenzymated and methylated forms, which are more readily used by the body—especially beneficial for individuals with MTHFR gene variations that affect folate and B12 metabolism.

The eight B vitamins—thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12)—each play distinct roles in energy production, neurotransmitter synthesis, red blood cell formation, and DNA repair. By providing them together, a B-complex ensures balanced support without the risk of depleting one nutrient through high doses of another.

How to Take B-Complex

Take two capsules daily with a meal, or as directed by your healthcare practitioner. B vitamins are water-soluble, so any excess is typically excreted in urine, which may turn bright yellow—a harmless effect from riboflavin. For best absorption, take with food to minimize potential stomach upset. If you are sensitive to B vitamins, you can start with one capsule and gradually increase to the recommended dose.

This supplement can be taken alongside other nutrients, but avoid combining with high-dose individual B vitamins unless advised, to prevent imbalances. Since B vitamins play a role in energy metabolism, many people prefer taking them in the morning or early afternoon to avoid interfering with sleep. Always read the label and follow the directions for use.

Side Effects and Interactions

B-complex supplements are generally well tolerated, but some individuals may experience mild nausea, headache, or digestive discomfort—especially on an empty stomach. The niacinamide form in this product eliminates the niacin flush, making it more comfortable for sensitive users. High doses of B6 (over 100 mg daily long-term) have been linked to nerve toxicity; this formula contains 25 mg of P-5-P, which is well within safe limits. Always adhere to the recommended dosage.

B vitamins may interact with certain medications, including anticonvulsants, diuretics, chemotherapy drugs, and medications for Parkinson's disease. If you are pregnant, nursing, or have a medical condition, consult your doctor before use. The inclusion of choline and TMG may affect blood pressure in some individuals; monitor accordingly.

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.
