Nutricost Methylated Vitamin B Complex, 120 Capsules – Gluten-free, 60 Servings

Key Ingredients & Forms

Nutricost's formula uses methylated B vitamins for superior bioavailability. Methylfolate (instead of folic acid) and methylcobalamin (instead of cyanocobalamin) are the active forms that require no further conversion in the body. This is especially beneficial for individuals with MTHFR gene variants who may struggle to activate standard B vitamins.

• Thiamine (B1) – Supports energy metabolism and nerve function.
• Riboflavin (B2) – Involved in electron transport and antioxidant protection.
• Vitamin B6 – Contributes to protein metabolism and neurotransmitter formation.
• Vitamin B12 (as methylcobalamin) – Essential for nerve health and DNA synthesis.
• Folate (as L-methylfolate) – Critical for cell division and homocysteine regulation.
• Biotin – Supports hair, skin, and nail health; involved in fatty acid metabolism.
• Minerals – Each serving provides zinc (for immunity), iron (for oxygen transport), magnesium (for muscle and nerve function), and iodine (for thyroid hormone production).

All ingredients are gluten-free and third-party tested for quality and purity.

Benefits of B complex

B vitamins play a central role in converting food into usable energy. Riboflavin and niacin are directly involved in mitochondrial energy production, while thiamine supports carbohydrate metabolism. Many users report improved vitality and reduced feelings of fatigue when supplementing with a complete B complex.

These nutrients also contribute to normal psychological function. B6, B12, and folate are essential for neurotransmitter synthesis, including serotonin and dopamine, which influence mood and cognitive clarity. Additionally, B12 and folate are vital for healthy red blood cell formation and oxygen transport throughout the body.

The minerals in this formula—zinc, iron, magnesium, and iodine—complement B vitamins by supporting immune function, oxygen delivery, muscle relaxation, and thyroid health. This multi-nutrient approach provides a foundation for overall wellness.

How to Take B complex

Take two capsules daily with 250-350 mL of water, preferably with a meal to enhance absorption. Consistent use is key for maintaining stable B vitamin levels. If you are taking other supplements, space them as needed to avoid gastrointestinal discomfort. Always follow the label or consult your health care provider.

Because B vitamins are water-soluble, excess amounts are excreted in urine, which may cause a harmless bright yellow discolouration—this is a normal effect of riboflavin.

Side Effects and Interactions

B complex supplements are generally well tolerated. Mild side effects may include nausea, stomach upset, or diarrhea, especially when taken on an empty stomach. High doses of B6 (over 100 mg daily) over prolonged periods have been linked to nerve toxicity, but this formula contains moderate amounts within safe limits.

B vitamins may interact with certain medications. For example, B6 can reduce the effectiveness of levodopa (used for Parkinson’s), and B12 supplements may interfere with some antibiotics. Iron and magnesium can affect absorption of thyroid medication and tetracycline antibiotics. Consult a health-care professional if you have underlying conditions or take prescription drugs.

Always read the label and follow directions for use. Any questions? Consult your healthcare practitioner. Keep out of reach of children.

What Is B complex?

A B complex includes eight crucial water-soluble vitamins that work together to support various bodily functions. These include energy production, cognitive performance, red blood cell formation, and nervous system health. Nutricost Methylated Vitamin B Complex provides a comprehensive blend of B vitamins in their bio-available forms, making it an efficient choice for individuals seeking targeted nutritional support.

Each serving supplies a balanced ratio of B1 (thiamine), B2 (riboflavin), B6 (pyridoxine), B12 (cobalamin), folate, and biotin, along with key minerals like zinc, iron, magnesium, and iodine. The inclusion of methylated forms—such as methylfolate and methylcobalamin—enhances absorption, particularly for those with genetic variations like MTHFR that impair conversion of standard B vitamins.

How to Choose the Right B complex

When selecting a B complex supplement, consider the form of each vitamin. Methylated forms are generally better absorbed, especially for those with digestive concerns or genetic polymorphisms. Nutricost’s formula uses active methylated B12 and folate, making it a suitable choice for a broad audience.

FAQ

Is this product suitable for vegans?

The methylcobalamin form of B12 is typically produced through fermentation and is considered vegan-friendly. However, if you have strict dietary preferences, confirm directly with the manufacturer, as other ingredients may vary.

How long does one bottle last?

Each bottle contains 120 capsules, providing 60 servings (two capsules daily), which lasts approximately two months.

Can I take this on an empty stomach?

While possible, taking B complex with food may reduce the risk of nausea and improve absorption. If you experience discomfort, try taking it with a meal.

Does this contain caffeine or stimulants?

No. This supplement contains B vitamins and minerals only, with no added caffeine or stimulants.

Why is my urine bright yellow after taking this?

That is due to riboflavin (B2), a water-soluble vitamin. The excess is excreted in urine, causing a harmless yellow colour.
