NOW Foods Vitamin C-1000 with Rose Hips & Bioflavonoids - 250 Tablets vs Holland & Barrett Vitamin D3 4000 IU (100mcg) Tablets - 120 Count

NOW Foods Vitamin C-1000 with Rose Hips & Bioflavonoids - 250 Tablets: NOW Foods Vitamin C-1000 with Rose Hips and Bioflavonoids is one of the best-value vitamin C products available in the UK, offering a well-rounded formula that goes beyond plain ascorbic acid. The addition of citrus bioflavonoids, rose hips, rutin, and acerola provides genuine synergistic benefits for absorption and antioxidant activity. The 250-count bottle represents outstanding long-term value. While the tablets are large, the overall package of quality, potency, and price makes this a strong default recommendation for daily vitamin C supplementation.

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.
