B-complex supplements are a practicable way to ensure you meet your daily needs for all eight essential B vitamins. Source Naturals B-50 Complex provides a balanced 50 mg dose of key B vitamins to contribute to your body's normal energy-yielding metabolism.*

Key Ingredients & Forms

Source Naturals B-50 Complex use standard, 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 Formulae offer methylated forms (e.g., methylfolate, methylcobalamin) for enhanced absorption, this product use 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.

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 contribute to normal energy-yielding 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.

Source Naturals B-50 Complex provides a balanced 50 mg base of key B vitamins (B1, B2, B3, B5, B6) plus appropriate levels of biotin, folate, and B12. This formulation is designed to fill nutritional gaps and support your body’s natural energy-yielding processes.*

Benefits of B-Complex

B vitamins are fundamental to converting food into usable energy. They help metabolise carbohydrates, fats, and proteins, fuelling your daily activities. Additionally, B vitamins contribute to:

• Healthy Nervous System: B1, B6, and B12 contribute to normal nerve function and neurotransmitter synthesis.
• Red Blood Cell Formation: B6, B9, and B12 play key roles in the normal formation of red blood cells.
• Stress Response: B5 contributes to normal adrenal function and helps the body manage stress.
• Skin, Hair & Nails: Biotin (B7) contributes to the maintenance of normal skin and hair.

Many people take B-complex to combat fatigue, improve mental clarity, and maintain steady energy levels throughout the day.*

How to Take B-Complex

Take 1 tablet 1 to 2 times daily, preferably with a meal to enhance absorption. Because B vitamins are water-soluble, it is 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 provider if you are taking medications or have any health conditions.

Side Effects and Interactions

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.
