Magnesium is a major mineral involved in hundreds of enzyme reactions, including muscle function, nerve signalling, energy production and bone health.

Support

What Magnesium does

Magnesium is best understood through its main roles in normal body function. The exact relevance depends on diet, health context, dose and product suitability.

Muscle function

Supports normal muscle contraction and relaxation.

Nerve support

Contributes to normal nerve signalling.

Energy metabolism

Helps enzymes involved in cellular energy pathways.

Sources

Where Magnesium comes from

Food sources are usually the starting point. Supplements may be considered when intake, needs, testing or professional advice suggests extra support is appropriate.

Nuts & seeds

Almonds, cashews, pumpkin seeds and sesame seeds can contribute.

Legumes & grains

Beans, lentils and whole grains provide magnesium.

Leafy greens

Dark green vegetables are useful dietary sources.

Forms

Common forms and label language

Mineral products may use different forms. Check the exact form, amount per serve, directions, warnings and whether the mineral already appears in another formula.

Magnesium glycinate

Often selected for gentle, steady magnesium support.

Magnesium citrate

Common form that may have a bowel-loosening effect in some people.

Magnesium malate

Often used in energy or muscle-support formulas.

Magnesium threonate

A more specialised form often discussed for cognitive support.

Safety

When to be careful

Minerals are essential, but more is not automatically better. Safety depends on dose, form, kidney function, medicines, age, pregnancy status and existing health conditions.

Kidney disease

Seek advice before supplementing if you have kidney disease.

Digestive tolerance

Some forms can cause loose stools, especially at higher doses.

Medicine timing

Separate from some antibiotics and bisphosphonates unless advised otherwise.
