Magnesium Citrate Capsules give you magnesium bound to citric acid, a form that dissolves readily and is absorbed well. Each capsule provides 85mg of magnesium and the label amount is two capsules twice a day with meals. One pot holds 90 capsules, which lasts about three weeks at that amount.
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. Citrate also draws a little water into the bowel, which many people welcome.
Magnesium Citrate Capsules are most useful for:
If you would rather have no effect on the bowel at all, Magnesium Bisglycinate (Glycinate) Capsules are the gentle form.
Each capsule provides 85mg of magnesium as citrate, which is 23% of the daily reference value. There are no fillers or binders, only magnesium citrate and the vegetable capsule shell.
Take two capsules twice a day with meals, or as your practitioner advises. If your stools loosen, take fewer capsules or take them earlier in the day.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
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.
How does magnesium citrate compare with bisglycinate and malate?
Citrate dissolves readily, is well absorbed and at higher amounts draws a little water into the bowel. Bisglycinate is the gentlest on the stomach and the usual evening choice, while malate is more often taken in the daytime for energy. All three are well absorbed, so the choice comes down to how your digestion responds.
How much magnesium citrate should I take a day?
Take two capsules twice a day with meals, which gives you 340mg of magnesium. For a lighter top up, two capsules once a day give 170mg and a pot then lasts six weeks.
When is the best time to take magnesium citrate?
Take it with meals, split across the day. If the citrate loosens your bowel, take it earlier in the day or take fewer capsules.
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 citrate have side effects?
Citrate has a mild loosening effect on the bowel at higher amounts, which many people welcome. If it is more than you want, take fewer capsules or choose bisglycinate, which has no effect on the bowel.
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.

Magnesium citrate is a well-absorbed form of magnesium that also has a mild osmotic effect, making it a common choice for those who want magnesium alongside digestive regularity.
Take with meals, split across the day. If you find the osmotic effect loosens the bowel, reduce the dose or take it earlier in the day.
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.
Each capsule gives you 85mg of elemental magnesium as citrate. At 2 capsules twice a day (340mg) a pot of 90 lasts about three weeks. At 2 capsules once a day (170mg) it lasts six weeks.
Citrate is magnesium bound to citric acid; it dissolves readily, is well absorbed, and at higher doses draws a little water into the bowel. Bisglycinate is bound to glycine, is the gentlest on the stomach and is the usual evening choice. Malate is bound to malic acid and is more often taken in the daytime. All three are well absorbed. Citrate suits people who want a well absorbed form that also keeps them regular.
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.
