Magnesium ascorbate is vitamin C bound to magnesium. It is a buffered form, so it is less acidic than plain ascorbic acid.
Vitamin C supports the immune system, the formation of collagen and the absorption of iron, and it contributes to the reduction of tiredness and fatigue. Magnesium adds support for muscles and energy release.
Each capsule provides a high dose of vitamin C with magnesium and nothing else apart from the vegetable shell. It is often chosen by people who find plain vitamin C hard on the stomach.
| Each capsule contains: | %NRV* | |
|---|---|---|
| Vitamin C | 485 mg | 606% |
| Magnesium | 36 mg | 10% |

Magnesium ascorbate is a buffered form of vitamin C, providing 485mg vitamin C plus 36mg magnesium per capsule. The magnesium buffers the acid, making it gentle on the stomach.
Take with meals, spread across the day, as vitamin C absorbs better in smaller doses. It pairs well with iron to support absorption.
Common signs include muscle cramps, poor sleep, low energy, and tension. A blood test can confirm your level.
Magnesium pairs well with vitamin D, zinc and B vitamins. Space it from calcium by around 2 hours for absorption.
Many people notice a difference within 1 to 2 weeks, with fuller benefits over 4 to 8 weeks of consistent use.
Magnesium ascorbate is vitamin C bound to magnesium, which makes it buffered, so it is less acidic in the stomach than plain ascorbic acid. Other buffered forms use calcium or sodium instead; the vitamin C is the same in each, the difference is which mineral comes with it. Ascorbic acid powder is the cheapest way to take a high dose and suits people who tolerate acid well. Magnesium ascorbate suits people who find plain vitamin C harsh on the stomach and want a little magnesium alongside.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
