Why customers take it

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. 

"..helps with my sleeping"

"Absolutely love these and I know they are helping with my sleeping now during the night and just genuinely feel good since I’ve been taking it" - Jackie S

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.

" levels"

"Initial response from taking magnesium is a small lift in energy levels....what a lovely company, very personal and polite with products of very high quality." - Chris E

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 emergency bathroom trips!

Why is magnesium important?

Getting enough magnesium is essential for maintaining good health, yet studies have indicated that potentially over 50% of people in the UK don't get enough in their diet. 


Magnesium is a mineral that play many vital roles around the body. All the cells in your body contain it and need it to function. It is crucial to processes such as energy creation, protein formation, gene maintenance, muscle movement, and nervous system regulation.

  • Your brain needs it to chemically enable normal sleep & relaxation.
  • Increasing levels can reduce stress/anxiety & might help with depression. 
  • Reduces tiredness/fatigue, treats migraines & boosts athletic performance.
  • Supports normal functioning nervous system & psychological functions.
  • Assists in regulating blood sugar levels & keeping blood pressure low.
  • Helps to retain hair pigment, slowing down the onset of greying hair.
  • Safe and effective natural laxative which can be used regularly to relieve constipation.

Why it's so good

  • Better absorbed, no tummy ache - VitaBright’s Magnesium Citrate is far more absorbable than the Magnesium Oxide commonly found in cheaper alternatives, which is hardly absorbed at all and often causes tummy cramps.
  • High dose - Each bottle provides a 4-month supply of 240 capsules delivering a potent 444mg of elemental magnesium per serving. 
  • Vegan - Our capsules are vegan, kosher and halal. 


Why choose us?

Junk and allergen free - We use the active ingredient only in a silky-smooth vegan capsule with absolutely no additives of any kind. This makes our magnesium free from gluten, dairy, wheat, lactose and other allergens, and free from all bulking agents and other junk. 


Made in UK - Like all our products, these capsules are made to exacting GMP standards in the UK. 



Take two capsules daily with food or as directed by your healthcare professional.


Do not exceed the stated dose.

  • If you experience diarrhoea, consider going down to one capsule a day or switching to Magnesium Glycinate instead. 
  • Although generally safe and well-tolerated, magnesium supplementation may not be suitable for people who take certain diuretics or heart medications. If you have a heart condition, consult your doctor before taking any magnesium supplement.
  • Magnesium can reduce the amount you absorb of certain antibiotics. If you need antibiotics, stop taking magnesium and resume when the course of antibiotics has finished. Note that this does not apply to all antibiotics, so we suggest you ask your pharmacist for guidance.
