Magnesium Supplements

Megan Hallett, Head of Nutrition at NOA, says:
"Magnesium plays a role in hundreds of processes in the body, including energy production, muscle function, sleep and mood. It's one of the nutrients people most often consider adding in when they're feeling tired, tense or struggling to switch off at night. Whether you actually need it, and how much, comes down to your individual picture. A NOA blood test looks at your energy, thyroid function, vitamin levels and more, so you get the fuller picture before deciding what your body actually needs, rather than starting with a guess."

Magnesium is found throughout your body; it's contained in every single cell, including your bones, muscles, soft tissue, fluids and blood.

Known as a "cofactor," meaning simply "a helper molecule", magnesium supports over 600 reactions that occur in your body, including converting food into energy, creating new proteins from amino acids, helping repair your DNA and RNA, aiding muscle concentration, and regulating neurotransmission.

When it comes to magnesium supplements, there is a range of different options. Knowing the key differences will help you to identify the right supplement for you.

Magnesium Glycinate: Choose for stress, anxiety, insomnia, and muscle relaxation. Magnesium binds to the amino acid glycine, while the glycine acts as a neurotransmitter that promotes calmness. Magnesium glycinate is the most gentle form of magnesium supplement and makes a great choice for those with a particularly sensitive stomach.

Magnesium Citrate: Choose for constipation, digestive discomfort and general deficiency. In this form, magnesium is bound to citric acid; the citrate helps to enhance solubility, making it a highly absorbable form of magnesium. We recommend that those with chronic digestive issues should typically avoid this form of magnesium. If you're ever unsure, always speak to your healthcare provider for advice or get in touch with our team of wellness experts.

Magnesium & Magnesium Oxide: This type of magnesium is bound to oxygen, and it is beneficial for symptoms including heartburn and indigestion. This more generic form of magnesium often contains a high concentration; however, the absorption rate is often lower than in magnesium glycinate or magnesium citrate.
