Regular Bowel Movements
Because of its absorption profile, magnesium citrate tends to draw a little water into the bowels - which can help relieve constipation gently. Since it tends not to cause gut cramps, it’s often seen as the gentler alternative to laxatives containing magnesium oxide. 

Feel More Energised
Magnesium helps combat tiredness and fatigue, supports your body’s metabolism for releasing energy from food, and keeps your electrolytes balanced so you can stay properly hydrated and on top form.

Strong Muscles & Steady Nerves
Magnesium contributes to normal muscle performance by helping transmit strong nerve signals, keeping your muscles hydrated. It’s also needed for protein building, and the smooth functioning of your nervous system.

Mind & Mood Support
Magnesium plays a role in maintaining normal psychological function, helping you stay focused and balanced.

Bones & Teeth You Can Rely On
By supporting and balancing the parathyroid gland which commands calcium around your body, magnesium is essential to preserve the strength and density of bones and teeth throughout life, through proper mineralisation. 

Cellular Health
Involved in the vital process of cell division, magnesium supports the healing and natural regeneration of your body at its most fundamental level, in everything from making new blood cells to growing muscle volume.

What is Magnesium Citrate Good For?

Regular Bowels

Magnesium Citrate is an osmotic laxative, which means it pulls water into your intestines to soften and bulk up your stool. It's popular as a gentle laxative that can be taken every day, as it doesn't cause urgency or gut cramps.

Calm and Sleep

Magnesium controls the balance between neurotransmitters that get us fired up and those that calm us down. This is why it's so popular as a sleep aid as well as an energy booster. Some people take it as a calming nutrient that eases jumpiness and feelings of agitation. 

Bones and Teeth

Magnesium is essential both to absorb Calcium, and to lay it down in your bones and teeth. People who need calcium supplements normally take Magnesium as well. 

Heart Health

As an electrolyte mineral, Magnesium conducts electricity and controls your heartbeat. You need magnesium to maintain a regular, steady heartbeat. It also supports overall cardiovascular health, and helps regulate blood pressure and the function of blood vessels.

Muscles and Energy

Popular for sports nutrition and people suffering from constant tiredness, Magnesium is essential for proper muscle function, including the contraction and relaxation of muscles. It helps regulate the flow of calcium ions, a key factor in muscle activity. It also helps convert food into energy by making ATP.

FAQs About Magnesium Citrate Tablets

VitaBright clean magnesium citrate tablets are vegan and free from all additives. They’re manufactured in the UK to pharmaceutical (GMP) standards and third-party tested for purity from heavy metals. They contain a strong dose of magnesium. Formulated for superior absorption, magnesium citrate is highly bioavailable and supports easy bowel movements.

Magnesium citrate tablets support muscle function, nerve health, and energy metabolism. They help reduce tiredness and fatigue, ease muscle cramps, and support electrolyte balance. According to the NHS and EFSA, magnesium also plays a role in maintaining healthy bones and psychological function. The citrate form is particularly effective for people with absorption issues.

Most people tolerate daily use well, and it may support better sleep, muscle recovery, and stress reduction over time. Stick to recommended doses (200 - 400mg per day) unless advised otherwise by your GP or a dietician. Taking two VitaBright magnesium citrate tablets daily can help maintain steady magnesium levels, especially if your diet is low in magnesium-rich foods.

Magnesium citrate is safe for most people when taken at the right dose. However, high doses of magnesium citrate can cause diarrhoea, nausea, or stomach cramps. If this happens, either go down to one capsule a day, or switch to magnesium glycinate or magnesium complex.

Most vitamins are safe to take with magnesium citrate tablets, but calcium, iron, and zinc may compete for absorption if taken at the same time. To maximise benefits, take magnesium and these minerals at different times of day. Also, magnesium may reduce the effectiveness of some antibiotics, so always check with a pharmacist if you’re on medication.

Signs of excess magnesium from supplements include diarrhoea and nausea. According to the NHS, taking magnesium supplements above 400mg daily can trigger these symptoms in some people. Magnesium supplements can cause issues for people with kidney conditions and they should therefore avoid them.

Magnesium citrate tablets may interfere with certain medicines, including antibiotics (like tetracyclines and quinolones), bisphosphonates (for osteoporosis), and diuretics. It can also affect drugs for thyroid conditions or Parkinson’s disease. To avoid interactions, take magnesium supplements at least two hours apart from other medications and consult a GP or pharmacist for personalised advice.

Magnesium absorption can be reduced by high intakes of calcium, phosphates (found in fizzy drinks), or foods high in oxalates, such as spinach and tea. Some gut conditions like coeliac disease, chronic diarrhoea, or use of proton pump inhibitors can also impair absorption. Using magnesium citrate tablets, which are highly bioavailable, can help counter this.

You can take magnesium citrate tablets at any time, but many people find taking them in the evening supports sleep and muscle relaxation. If magnesium has a mild laxative effect, night-time use may help avoid daytime discomfort. Consistency matters more than timing, so take it at the same time each day.

Yes, magnesium citrate tablets and vitamin B12 can be taken together safely. They support different processes in the body. Magnesium helps with muscle and nerve function, while B12 supports red blood cell formation and neurological health. Taking them together may enhance energy and reduce fatigue when used as part of a balanced supplement routine.

For healthy individuals, magnesium citrate tablets are generally safe. However, people with kidney disease should avoid magnesium supplements unless advised by a doctor, as their kidneys may struggle to excrete excess magnesium. Always speak to a doctor if you have kidney concerns before starting magnesium.

    Capsules that are easy to take

    I was recommended these capsules by a friend. My magnesium levels were low and she recommended I order them for vitabrite because they're vegan and have no binders or fillers. She was sure they would help me without causing other issues. I recommend them to other friends.

Customer Questions

  • AP
    The ingredients in your 'Magnesium Citrate 1480mg Providing 444mg Elemental Magnesium per Serving' product are listed as magnesium citrate and magnesium oxide, but magnesium oxide absorbs very poorly. What is the volume of magnesium citrate compared to magnesium oxide in this formula?
    VitaBright

    Magnesium Citrate accounts for 70% of the total.

  • Monica
    What age is this preparation suitable for?
    VitaBright

    This is a high-strength supplement and is formulated for those aged 18 and over.

  • David B.
    Can I open these capsules and mix the contents with food or drinks?
    VitaBright

    Yes, this supplement will be just as effective if you open the capsules. Just twist the capsules open and mix the contents with a drink or food. This isn't formulated to dissolve like a soluble supplement, so you will need to mix it into something thick like a smoothie or soup so that it doesn't settle at the bottom.

  • Dominic C.
    Is your Magnesium gluten free?
    VitaBright

    Yes it is gluten free

  • Dylan G.
    How much elemental magnesium is in your magnesium supplements?
    VitaBright

    A daily serving of our Magnesium Glycinate contains 300mg of elemental magnesium and 1200mg of glycine, the "other half" of the molecule that the magnesium is bound with. Our Magnesium Citrate contains 440mg of elemental magnesium.

  • Easton C.
    Your Magnesium is of a higher strength and instructions are to take 2 a day. I have just looked online seen an adult shouldn't take any more the 420mg a day. Is this recommended dosage safe to take?
    VitaBright

    Different medical authorities advise different daily amounts of magnesium, and there isn't an official maximum limit. It's thought that excess magnesium causes diarrhoea and isn't absorbed through the intestine. (Medically recorded cases of magnesium overdose were caused by magnesium sulphate being given in hospital directly into the bloodstream, not through people taking food supplements.) The NHS advises that the necessary amount of magnesium is 300mg a day for men and 270mg a day for women (aged 19 to 64 years). It says that taking more than 400mg of magnesium can cause diarrhoea, and this is true for some people, particularly if you take magnesium oxide or magnesium citrate. By contrast, in America the recommended daily intake of magnesium is set much higher, at 420mg daily for men and 320mg daily for women. Bear in mind that this weight of 400mg refers to the elemental magnesium, not the total weight of the magnesium compound. For example, a daily serving of our Magnesium Glycinate contains 300mg of elemental magnesium and 1200mg of glycine, the "other half" of the molecule that the magnesium is bound with. Our Magnesium Citrate contains 440mg of elemental magnesium. If you have any concerns about how much magnesium you personally should be taking, we recommend that you speak to your doctor or dietician for personal advice.

  • Easton U.
    Which vitamins would help with constipation?
    VitaBright

    Magnesium Citrate is popular as a gentle relief for constipation. However if you suffer from severe constipation frequently, please see your doctor to check for signs of other problems.

  • Eli B.
    Is your magnesium chelated?
    VitaBright

    Yes, all our magnesium supplements contain chelated magnesium compounds, which are magnesium in an organic compound for better absorption.

  • Maverick E.
    Why does your Magnesium Glycinate bottle say 1500mg when it only contains 300mg elemental magnesium?
    VitaBright

    Magnesium supplements never contain pure magnesium as an element, because it bursts into flames at room temperature. Instead, they contain a magnesium compound, consisting of magnesium plus an organic element that makes it easy to absorb. A 1500mg daily serving of our Magnesium Glycinate contains 300mg of elemental magnesium and 1200mg of glycine, the "other half" of the molecule that the magnesium is bound with. Glycine is an amino acid that our bodies can make, but which we also eat in meat.
