Nutrient quality
70 High impact
The product provides good potencies but primarily uses standard, rather than more bioavailable or active, forms of B vitamins, which limits its quality score compared to advanced complexes.
Analysis
This NOW B-100 product offers a comprehensive blend of B vitamins, with many in a '100' potency, meaning 100mg or 100mcg for most key B vitamins per serving. Its sustained-release format is a key feature, aiming to provide a gradual release of nutrients over time, which can be a gentler approach for the body compared to an immediate flush.
The formulation includes common forms like Pyridoxine Hydrochloride for B6 and Cyanocobalamin for B12. It also adds cofactors like Choline, Inositol, and PABA, which can contribute to the overall intended benefits of a B-complex. This makes it a practical choice for individuals seeking a broad spectrum B vitamin supplement in a sustained delivery system.
