What is it?

Holland & Barrett’s Magnesium tablets contain 375mg of Magnesium to support healthy bones and muscles, as well as helping to reduce tiredness and fatigue. Magnesium is one of the most abundant minerals in your body. It helps with hundreds of processes, including helping enzymes that are responsible for converting food into energy and extracting nutrients.

  • Contributes To the Maintenance of Normal Bones and Muscles
  • Contributes To the Reduction of Tiredness and Fatigue
  • Suitable For Vegetarians and Vegans

What Are the Benefits of This Supplement?

  • Magnesium is important when it comes to strong bones and healthy teeth. Most Magnesium can be found in your bones; It stimulates calcitonin, which helps to keeps bones strong by absorbing calcium from the blood and directing it into your bones.
  • Magnesium is also present in other tissues such as your muscles and joints. As it benefits normal muscle function, it’s important in the contraction and relaxation of your heart. It also works as a natural blocker to calcium – which triggers muscle contractions – helping the cells relax.
  • Magnesium is so important for energy release, it is also critical in a lot of other bodily processes, such as the nervous system.
