Ashwagandha KSM-66 Capsules

£7.99 for 60 servings at WeightWorld. It carries more than one active ingredient, so it is not ranked against single-ingredient products. Each price below counts one ingredient only.

What it really costs, per 600 mg16pOne 600 mg dose is our comparison unit for ashwagandha. It is not a recommendation.
A day16p
A week£1.12
A month£4.79
A year£58.33

At one 600 mg dose a day, this pack lasts 50 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Ashwagandha

  • In the pack: 60 × 500 mg = 30 g
  • £7.99 ÷ 30 g × 600 mg = 16p per 600 mg
  • A week 16p × 7 = £1.12 · a month × 30 = £4.79 · a year × 365 = £58.33
  • Amount per serving: extract weight stated on the label.

Black pepper (piperine)

  • In the pack: 60 × 400 mg = 24 g
  • £7.99 ÷ 24 g × 5 mg = 0.166p per 5 mg
  • A week 0.166p × 7 = 1p · a month × 30 = 5p · a year × 365 = 61p
  • Amount per serving: extract weight stated on the label.

Vitamin B6

  • In the pack: 60 × 3.2 mg = 192 mg
  • £7.99 ÷ 192 mg × 50 mg = £2.08 per 50 mg
  • A week £2.08 × 7 = £14.57 · a month × 30 = £62.42 · a year × 365 = £759.47
  • Amount per serving: stated on the label.
