Source Naturals B-50 Complex – Supports Energy Production – 50 mg – 100 Tablets

Benefits of B-Complex

Discover Source Naturals B-50 — B vitamins are essential for converting the food you eat into usable energy. They help your body metabolise carbohydrates, fats, and proteins, fuelling your daily activities. In addition, B vitamins support:

• Healthy Nervous System: Vitamins B1, B6, and B12 contribute to normal nerve function and neurotransmitter synthesis.
• Red Blood Cell Formation: B6, B9 (folate), and B12 play key roles in the formation of healthy red blood cells.
• Stress Response: Vitamin B5 (pantothenic acid) supports adrenal function and helps the body manage stress.
• Skin, Hair & Nails: Biotin (B7) is known for supporting healthy skin and strong nails.

Source Naturals B-50 Complex provides a balanced 50 mg base of primary B vitamins, plus appropriate levels of biotin, folate, and B12, to help fill nutritional gaps and support your body's natural energy production processes.*

How to Take B-Complex

Take 1 tablet 1 to 2 times daily, preferably with a meal to enhance absorption. Since B vitamins are water-soluble, it's better to spread intake throughout the day rather than taking a large dose all at once. Consistent daily use helps maintain optimal levels. B-complex can be taken alongside other supplements, but consult your health-care practitioner if you are taking any medications or have any health conditions.

Key Ingredients & Forms

Source Naturals B-50 Complex uses well-researched forms of each B vitamin: thiamine mononitrate (B1), riboflavin (B2), niacinamide (B3), d-calcium pantothenate (B5), pyridoxine hydrochloride (B6), biotin, folic acid (B9), and cyanocobalamin (B12). Each tablet delivers 50 mg of the primary B vitamins, with lower doses for biotin, folate, and B12 to align with daily needs.

While some premium formulas offer methylated forms (e.g., methylfolate, methylcobalamin) for enhanced absorption, this product uses standard forms that are effective for most individuals. If you have MTHFR gene variants, you may want to consider a methylated version, but many people thrive on this classic formulation.

How to Choose the Right B-Complex

When selecting a B-complex supplement, consider dosage, form, and certifications. Source Naturals B-50 Complex provides 50 mg of most B vitamins—a moderate dose suitable for daily maintenance.

Side Effects and Interactions

B-complex supplements are generally safe for most people. High doses may cause mild side effects like nausea, headache, or dizziness. A common and harmless effect is bright yellow urine, caused by excess riboflavin (B2) being excreted. This is normal and indicates your body has absorbed what it needs.

B-complex can interact with certain medications, including anticonvulsants, chemotherapy drugs, and antibiotics. If you are on medication, speak with your health-care practitioner before starting supplementation.

What Is B-Complex?

B-complex supplements deliver all eight essential B vitamins—B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). These vitamins work synergistically to support energy metabolism, nervous system function, and red blood cell formation. Because they are water-soluble, the body does not store them efficiently, making consistent intake important for overall wellness.
