Quantity: 4
NOW Ultra B-12 is a comprehensive liquid B-complex supplement formulated to support a wide range of health goals, particularly energy production, neurological function, and skin, hair, and nail health. Its key feature is the extremely high dosage of Vitamin B-12, providing 15mg per serving in a synergistic blend of three forms: Methylcobalamin, Dibencozide, and Cyanocobalamin, aiming for maximum absorption and utilization. The liquid format is often preferred for rapid absorption and ease of use, especially for individuals who have difficulty swallowing pills, and contains a robust profile of other essential B vitamins like Folate, Biotin, Niacin, B6, Riboflavin, and Thiamine, making it a powerful supplement for overall vitality and metabolic support.
- Extremely high dose of Vitamin B-12 (15mg) in three bioavailable forms (Methylcobalamin, Dibencozide, Cyanocobalamin) to support diverse physiological needs.
- Liquid form allows for rapid absorption and is easy to consume for those who dislike pills, enhancing user compliance.
- Comprehensive B-complex includes a wide spectrum of B vitamins vital for various bodily functions, providing holistic support.
- Cost-effective per serving for a liquid high-potency complex, offering good value for its comprehensive nutrient profile.
- The B12 dosage (15mg) is significantly higher than most individuals require and may be excessive for daily general use without a specific diagnosed deficiency, potentially leading to unnecessary intake.
- Some B vitamin forms, like Pyridoxine Hydrochloride (B6) and Folic Acid (Folate), are not the most active or bioavailable forms (e.g., P5P or L-Methylfolate), which might limit efficacy for individuals with genetic variations in nutrient metabolism.
- The Riboflavin (B2) content is relatively low (3.4mg) compared to the very high doses of other B vitamins in the formula, potentially underdosing this specific component.
- The extremely high B12 dosage may lead to harmless bright yellow urine due to excess vitamin excretion, which can be alarming if unexpected.
- Individuals sensitive to Niacin may experience a temporary 'niacin flush' (redness, itching, warmth) due to the inclusion of Niacin (Vitamin B3), despite Niacinamide also being present to mitigate this effect.
