Magnesium Phosphate Capsules give you magnesium bound to phosphate, so you get both minerals in one moderate amount. Each capsule provides 99mg of magnesium and you take one a day with food. One pot holds 90 capsules, which is a 90 day supply.
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. Phosphorus, the other half of this capsule, is part of bone and of energy release inside cells.
Magnesium Phosphate Capsules are most useful for:
For a higher amount per capsule, Magnesium Bisglycinate (Glycinate) Capsules provide 133mg.
Each capsule provides 99mg of magnesium, which is 26% of the daily reference value. There are no fillers or binders, only magnesium phosphate and the vegetable capsule shell. Mag phos is the short name for it.
Take one capsule a day with food, which supports absorption. It can be taken on its own or alongside another magnesium form if you are aiming at different things.
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 phosphate compare with citrate and bisglycinate?
Phosphate gives both minerals in a moderate amount with no loosening effect on the bowel. Citrate is well absorbed but can loosen the bowel at higher amounts, while bisglycinate is the gentlest and the usual evening choice.
How much magnesium phosphate should I take a day?
Take one capsule a day with food, which gives you 99mg of magnesium.
When is the best time to take magnesium phosphate?
Take it with a meal at any time of day, because food supports absorption.
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 phosphate have side effects?
Phosphate has no loosening effect on the bowel, so the only thing to do is take it with food to keep it easy on the stomach.
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 phosphate delivers both magnesium and phosphorus, minerals that work together in energy and cellular function. It has a traditional association with nerve and muscle comfort.
Take one capsule per day with a meal, which supports 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.
Phosphate is magnesium bound to phosphate, so each capsule gives both minerals in a moderate dose with no loosening effect on the bowel. Citrate is well absorbed but can loosen the bowel at higher doses. Bisglycinate is bound to glycine and is the gentlest, the usual evening choice. Phosphate is often chosen by people who want magnesium without a laxative effect and who also want a little phosphorus, which is part of bone and of energy release.
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.
