★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
Magnesium Carbonate Capsules give you magnesium as a mineral salt that reacts with stomach acid to form magnesium chloride, the form that is then absorbed. Each capsule provides 117.5mg of magnesium and you take one a day with food. One pot holds 90 capsules, which is a 90 day supply.
Benefits of taking magnesium carbonate
Magnesium is a mineral your body uses in more than 300 enzyme systems, from turning food into energy to sending nerve signals and contracting muscles. Carbonate is alkaline, which is why it needs stomach acid to release its magnesium and why it is taken with a meal.
- Energy levels pick up as tiredness and fatigue ease.
- Muscles contract and relax as they should.
- Nerves get the magnesium they use to send signals.
- Bones and teeth stay healthy with the magnesium they contain.
Who benefits
Magnesium Carbonate Capsules are most useful for:
- People who want 117.5mg of magnesium in one capsule a day, taken with a meal.
- Anyone who wants a plain mineral salt with nothing added.
- Those who have been advised the carbonate form by a practitioner.
If you want a form that does not depend on stomach acid, Magnesium Bisglycinate (Glycinate) Capsules are the gentle choice, while Magnesium Citrate Capsules dissolve readily on their own.
What is in it
Each capsule provides 117.5mg of magnesium as carbonate, which is 31% of the daily reference value. There are no fillers or binders, only magnesium carbonate and the vegetable capsule shell. Magnesium(II) carbonate and MgCO3 are other names for it.
How to take it
Take one capsule a day with food. The meal matters with this form, because stomach acid is what turns the carbonate into magnesium chloride for absorption.
Diet and allergens
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
Quality
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Common questions
How does magnesium carbonate compare with citrate, bisglycinate and oxide?
Carbonate is a mineral salt that needs stomach acid to release its magnesium. Citrate is already dissolved and absorbs well but can loosen the bowel at higher amounts. Bisglycinate is bound to glycine, is the gentlest on the stomach and is the usual evening choice. Oxide carries the most magnesium by weight but the least is absorbed. Carbonate suits people who want one plain capsule a day with a meal.
How much magnesium carbonate should I take a day?
Take one capsule a day, which gives you 117.5mg of magnesium, 31% of the reference value. A pot of 90 lasts three months.
When is the best time to take magnesium carbonate?
With a meal, at whichever time of day you will remember it. Food brings the stomach acid the carbonate needs.
Can I take it with other supplements?
Yes. Your body uses magnesium to regulate the active form of vitamin D, so the two are often paired to look after bones. Zinc and the B vitamins are other common pairings, while calcium is best taken about two hours apart because the two compete for absorption.
Does magnesium carbonate have side effects?
It is well tolerated at one capsule a day with food. If you take prescribed tablets, are pregnant or breastfeeding, speak to your GP or pharmacist first.
What are the signs I might need magnesium?
Muscle cramps, poor sleep, low energy and tension are the signs people most often report. A blood test can confirm your level.

Frequently asked questions
What is Magnesium Carbonate good for?
Magnesium carbonate provides systemic magnesium while also acting as a mild antacid, neutralising excess stomach acid. It suits those wanting magnesium plus occasional acid comfort.
When should I take Magnesium Carbonate?
Take with food, which provides the stomach acid needed to convert it for absorption. For acid comfort, it can be taken after a meal.
What are signs I might need magnesium?
Common signs include muscle cramps, poor sleep, low energy, and tension. A blood test can confirm your level.
Can I take magnesium with other supplements?
Magnesium pairs well with vitamin D, zinc and B vitamins. Space it from calcium by around 2 hours for absorption.
How long until I notice results?
Many people notice a difference within 1 to 2 weeks, with fuller benefits over 4 to 8 weeks of consistent use.
How does magnesium carbonate compare with citrate, bisglycinate and oxide?
Carbonate is a mineral salt that needs stomach acid to release its magnesium, and it is alkaline, so it settles acid at the same time. Citrate is already dissolved and absorbs well but can loosen the bowel at higher doses. Bisglycinate is bound to glycine, is the gentlest on the stomach and is the usual evening choice. Oxide carries the most magnesium by weight but the least is absorbed. Carbonate suits people who want a high magnesium dose per capsule and welcome the antacid effect; it is best taken with a meal.
Why capsules rather than tablets?
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.
