NOW Foods MK-7 Vitamin K-2 100mcg - 60 Veg Capsules vs Holland & Barrett Vitamin D3 4000 IU (100mcg) Tablets - 120 Count

NOW Foods MK-7 Vitamin K-2 100mcg - 60 Veg Capsules: NOW Foods MK-7 Vitamin K2 100mcg is a well-formulated standalone K2 product using the clinically validated MenaQ7 form. The soy-free sourcing is a genuine differentiator in the K2 market, where many products rely on natto. At 100mcg per capsule, it delivers the dose most commonly used in clinical research on cardiovascular and bone health. The veg capsule format and clean ingredient list make it suitable for vegans, and the NOW Foods GMP certification provides solid quality assurance.

Holland & Barrett Vitamin D3 4000 IU (100mcg) Tablets - 120 Count: Holland & Barrett's Vitamin D3 4000IU is a functional, affordable option that delivers an effective dose at the lowest price in its category. User blood test results confirm it works for raising vitamin D levels. However, the tablet format with bulking agents is less elegant than oil-based softgels, and absorption may be somewhat reduced without a lipid carrier. It is best suited for budget-conscious consumers who prioritise price over formulation quality.
