Vitamin D3 2000IU Tablets
£14.99 for 400 servings at WeightWorld. That works out at 2p per 1,000 IU, which ranks it 27th of the 207 vitamin D3 products we price across 20 UK retailers.

How we worked it out
- In the pack: 400 × 2,000 IU = 800,000 IU
- £14.99 ÷ 800,000 IU × 1,000 IU = 1.87p per 1,000 IU
- A week 1.87p × 7 = 13p · a month × 30 = 56p · a year × 365 = £6.84
