Natural Factors High Potency B Complex, 90 Capsules

Key Ingredients & Active Forms

Natural Factors High Potency B Complex provides a carefully balanced blend of all eight essential B vitamins, including the body-ready forms methylcobalamin (B12) and methylfolate (B9). These active forms are particularly advantageous for individuals with MTHFR gene variations who may struggle to convert synthetic versions. Each nutrient is dosed to contribute to normal energy-yielding metabolism and the normal function of the nervous system.

• B1 (Thiamine) – 100 mg – contributes to normal energy-yielding metabolism and normal functioning of the nervous system.
• B2 (Riboflavin) – 50 mg – contributes to normal energy-yielding metabolism and maintenance of normal skin.
• B3 (Niacin) – 50 mg – contributes to normal energy-yielding metabolism and maintenance of normal skin.
• B5 (Pantothenic Acid) – 50 mg – contributes to normal energy-yielding metabolism and normal mental performance.
• B6 (Pyridoxine) – 50 mg – contributes to normal energy-yielding metabolism, normal homocysteine metabolism, and normal psychological function.
• B7 (Biotin) – 300 mcg – contributes to maintenance of normal hair and skin.
• B9 (Folate) – 400 mcg – as methylfolate for superior absorption; contributes to normal amino acid synthesis and normal blood formation.
• B12 (Cobalamin) – 500 mcg – as methylcobalamin for nerve and red blood cell health; contributes to normal red blood cell formation and normal functioning of the nervous system.

Manufactured in Natural Factors’ own facilities, each batch undergoes rigorous testing to ensure purity and potency.

What Is B-Complex?

B-Complex refers to the group of eight essential B vitamins that work synergistically to support overall health. This Natural Factors formula delivers a balanced blend of B1, B2, B3, B5, B6, B7, B9, and B12. These vitamins are crucial for converting food into energy and maintaining a healthy nervous system. Many people turn to B-complex supplements to fill dietary gaps or address low energy and occasional fatigue. Natural Factors goes a step further by sourcing ingredients from certified organic farms and using non-GMO, non-hybridised seeds. This commitment to quality ensures a pure, potent product.

How to Choose the Right B-Complex

Not all B-complex supplements are created equal. Look for active forms like methylfolate and methylcobalamin to skip conversion steps. Natural Factors High Potency B Complex delivers these bioavailable forms. The product is also certified organic, non-GMO, and free from common allergens like gluten, dairy, and soya. If you follow a vegan or vegetarian diet, this supplement is suitable—the B12 is sourced from fermentation, not animal products.

Dosage matters. While some Formulae exceed the Daily Value by small margins, this high-potency blend provides higher amounts to support those with greater needs, such as older adults, athletes, or individuals under chronic stress. Always consult a health care professional before starting a new supplement regimen.

Benefits of B-Complex

B vitamins play a fundamental role in energy metabolism. They help break down carbohydrates, fats, and proteins into usable fuel, making them a go-to for those seeking sustained energy throughout the day. The nervous system also relies on B vitamins—especially B6, B9, and B12—to maintain normal function and contribute to normal psychological function. Healthy skin, hair, and eyes are additional benefits linked to this vitamin family. Because B vitamins are water-soluble and not stored in large amounts, regular intake is important. Natural Factors High Potency B Complex provides a high-potency formula to help meet daily needs.

How to Take B-Complex

Take one capsule daily with food to enhance absorption and minimise any potential stomach upset. Because B vitamins are water-soluble, it’s better to take them with a meal that contains some fat for optimal uptake. Morning is often recommended, as B vitamins can provide an energising effect. Avoid taking late in the day if you are sensitive to stimulation. Consistency is key—regular daily use helps maintain steady levels in the body. Store in a cool, dry place away from direct sunlight.

Side Effects and Interactions

B-complex is generally well-tolerated, but some people may experience nausea, upset stomach, or a harmless bright yellow urine due to riboflavin excretion. High doses of niacin can cause a temporary “niacin flush” (redness, warmth, tingling), whilst this formula use a modest 50 mg of niacinamide, which is less likely to cause that reaction. Certain medications, including antibiotics, antiseizure drugs, and chemotherapy agents, can interfere with B vitamin absorption or increase requirements. If you are on medication or have a medical condition, consult your health care provider before use.
