Holland & Barrett Vitamin D3 4000 IU (100mcg) Tablets - 120 Count vs Life Extension Two-Per-Day Multivitamin - 120 Tablets
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.

Life Extension Two-Per-Day Multivitamin - 120 Tablets: Life Extension Two-Per-Day is arguably the best-value research-grade multivitamin available in the UK market, offering doses well above standard RDAs and using superior bioactive forms throughout. The inclusion of lutein, lycopene, and multiple forms of selenium demonstrates Life Extension's evidence-based approach. While the tablets are large and the excipient list is longer than simpler products, this is inherent to cramming a comprehensive formula into just two tablets. It represents a significant upgrade over high-street multivitamins at a modest price premium.
