Comparisons / NOW Foods Vitamin D3 5000 IU vs Nutrabay Vitamin D3 + K2
**Verdict: Nutrabay Vitamin D3 + K2 wins for most Indian consumers** Nutrabay scores 8.3/10 versus NOW Foods' 6.9/10, a significant 1.4-point difference driven by superior formulation and dosing strategy. The critical differentiator is Nutrabay's inclusion of Vitamin K2 (100mcg), which enhances calcium absorption and directs it to bones rather than arteries—a crucial benefit NOW Foods lacks entirely. This combination formula earns Nutrabay an 8.8 formula score compared to NOW's perfect 10.0 for single-ingredient purity. NOW Foods' catastrophic 0.1 dosing score stems from its 5000 IU (125mcg) dose—far exceeding India's recommended 600-800 IU daily intake and approaching the 4000 IU upper safety limit. Nutrabay's 2000 IU is more appropriate for daily supplementation, earning it a 7.2 dosing score. NOW Foods costs ₹3.71 per serving (₹2.94 less than Nutrabay's ₹6.65), giving it a 9.6 value score. However, this price advantage doesn't justify the excessive dosing risk. **Choose Nutrabay** for safe, synergistic daily supplementation. **Choose NOW Foods only** if a healthcare provider specifically prescribes high-dose Vitamin D3 for deficiency correction, not for maintenance.
