Magnesium cost per day: a worksheet for the full serving
Share
To work out a magnesium supplement's daily cost, divide the pack price by the number of complete labelled daily servings. Dividing by capsule count answers a different question. Delivery can also change the result, especially on a single-pouch order.
This worksheet uses Hyoomen's displayed magnesium price and directions on 7 November 2026. It is a calculation example, not a cheapest-product ranking or a reason to change your serving.
Start with the number of complete daily servings
Hyoomen Magnesium Glycinate contains 90 capsules per pouch. Its daily direction is three capsules, providing 225 mg elemental magnesium.
The serving calculation is:
90 capsules divided by three capsules per day = 30 daily servings.
At the displayed £9.99 pack price, £9.99 divided by 30 = £0.333 per labelled day, or about 33.3p before delivery. Dividing £9.99 by 90 instead would give 11.1p per capsule, not the daily cost.
That distinction matters when comparing a one-capsule product with a three-capsule product. Capsule count alone cannot tell you which pack lasts longer.
Put delivery in a separate line
The same product page lists £1.99 standard UK delivery and free shipping on orders over £30. For an order consisting of one £9.99 pouch, with that delivery charge and no other adjustment, the workings are:
| Item | Amount |
|---|---|
| Product | £9.99 |
| Standard delivery | £1.99 |
| Order total | £11.98 |
| Full daily servings | 30 |
| Delivered cost per daily serving | £11.98 divided by 30 = approximately 39.9p |
The delivery charge adds about 6.6p per serving in this example. It does not change the magnesium amount or the number of servings.
Use the charge actually shown for your order. A different destination, basket, offer or delivery choice can change the total. A free-delivery threshold is not a recommendation to buy extra products or more stock than you need.
Compare two packs without changing either direction
For each product you are considering, write down these five values:
- The price for the purchase option you would actually select.
- The number of capsules or tablets in the pack.
- The labelled number taken daily.
- The elemental magnesium in that daily serving.
- The delivery charge applicable to that order.
Calculate the daily cost from the first three values. Keep the elemental amount beside the result. Two daily servings at different mineral amounts are not identical quantities, even if their costs match.
Do not increase a product's labelled serving to make it match another product. Nor should a low price per milligram become a target for taking more magnesium. Our magnesium capsules guide explains the wider label checks.
Separate first-order offers from ongoing purchases
If a seller offers a subscription, a first-order discount or a multi-pack, record the conditions with its price. The first payment and a later recurring payment may differ. The quantity dispatched may also cover more than one month.
A useful comparison has separate lines for the initial order and the order you would receive afterwards. Include the relevant delivery each time. Do not count a discount that has not been applied, or assume free delivery repeats automatically.
This worksheet does not assume a subscription price for Hyoomen. It uses the £9.99 displayed pack price and the stated standard delivery charge as a dated example.
Use the result as a budget figure
Daily cost tells you what a labelled routine costs under the recorded purchase conditions. It does not measure absorption, suitability or health outcomes. Ingredients, dietary requirements and the complete daily amount still matter.
If you want to consider Hyoomen's single-source glycinate formula, check its current price, three-capsule directions and order options. Recalculate if any input changes.
