Nutri Advanced Vitamin D3 with K2 Liquid Drops 30ml vs Holland & Barrett Vitamin D3 4000 IU (100mcg) Tablets - 120 Count
Nutri Advanced Vitamin D3 with K2 Liquid Drops 30ml: Nutri Advanced D3 with K2 is a thoughtfully formulated practitioner-grade product that combines two synergistic nutrients in an exceptionally clean liquid format. The MCT oil base supports absorption and the MK-7 form of K2 has the longest half-life of any K2 variant. The flexible dosing is a genuine advantage for practitioners managing individual patient needs. However, the relatively low per-drop D3 content means higher doses require many drops, and the product is harder to find than mainstream alternatives.

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.
