Swiss BioEnergetics magnesium citrate: quick verdict
This is the clearest value proposition of the three Swiss magnesium products reviewed here: one capsule states 500mg magnesium citrate and 150mg elemental magnesium, with 120 capsules for £9.97. The published elemental figure makes comparison easier, although a low item price also means a single bottle falls below the current free-delivery threshold.
Why the label shows both 500mg and 150mg
The 500mg number refers to magnesium citrate, the whole mineral compound. The 150mg number is the elemental magnesium supplied by one capsule. For comparing supplements against guidance or another bottle, the elemental amount is the more useful figure.
This distinction is important because product titles often lead with the larger compound number. Swiss BioEnergetics does publish the elemental amount for citrate, which is more transparent than a compound-only label.
Price, referral saving and delivery
| Measure | At listed £9.97 | If 20% code applies |
|---|---|---|
| Item price | £9.97 | about £7.98 |
| Cost per 120-capsule day | about 8.3p | about 6.7p |
| Free standard delivery | Current threshold is £35; check the post-discount basket | |
The code calculation is illustrative. Confirm JEREMYFARRAR is accepted for this product and whether a sale or subscription can be combined. A small basket can lose more to delivery than it gains from a headline discount.
What is actually in the bottle?
- 500mg magnesium citrate per capsule, stated to provide 150mg elemental magnesium.
- 120 capsules and directions of one capsule daily.
- HPMC capsule shell.
- UK manufactured, according to the official listing.
The NHS states that magnesium contributes to normal body functions and that most people should obtain what they need from a varied diet. It also warns that high supplemental doses can cause diarrhoea. A product review cannot tell you whether you need a supplement or diagnose low magnesium.
Citrate compared with Swiss glycinate
Citrate wins on published dose clarity and lowest item cost per day. Glycinate is sold as a chelated form and has flexible one-to-three-capsule directions, but its current page does not clearly give elemental magnesium per capsule. If exact dose comparison matters, that missing number should influence the decision.
How to compare the real cost of a small bottle order
At the displayed prices, the item is inexpensive enough that postage can dominate a one-bottle order. If the 20% code is accepted, the item-only calculation is about £7.98. Adding the currently listed £4.95 standard shipping would produce a materially different delivered figure. The live checkout is the authority because thresholds and code stacking can change.
Adding extra products solely to reach free delivery is not automatically a saving. Compare the amount you intended to spend with the final basket, not with a hypothetical shipping charge. A planned multi-product order may cross the threshold naturally; an unplanned add-on can cost more than postage.
One bottle
Best for avoiding excess stock, but most exposed to the below-threshold delivery charge.
Several bottles
May improve delivered cost per bottle, but only if the expiry date and your intended use make bulk buying sensible.
Mixed basket
Can reach free delivery without duplicating one supplement. Recheck every ingredient to avoid overlapping daily amounts.
Subscription
Compare renewal frequency, future price and cancellation terms—not only the first percentage shown.
Questions the citrate label answers well
The page publishes the compound amount, elemental amount, capsule count, daily serving and stated supply duration. Those five facts allow meaningful price-per-day and dose comparisons. Before purchase, still verify the current pack, allergy information, expiry date, returns conditions and whether any medicine-specific advice applies to you.
A review should also distinguish nutritional information from sales language. Phrases such as “high potency”, “easily absorbable” or “highly bioavailable” need evidence and context; the concrete decision points remain 150mg elemental magnesium, one capsule daily, 120 servings and the delivered price.
Magnesium citrate FAQs
How much elemental magnesium is in one capsule?
The official listing states 150mg elemental magnesium from 500mg magnesium citrate.
How long does 120 capsules last?
The directions state one capsule daily, so the bottle is presented as a 120-day supply.
Is the 20% code guaranteed to stack with the sale price?
No. Use JEREMYFARRAR and check the final basket; the merchant controls stacking and exclusions.
