Frequently Asked Questions

Answers to common questions about magnesium supplements

Magnesium is an essential mineral involved in over 300 enzymatic processes in the body. It plays a key role in supporting muscle and nerve function, maintaining healthy bones and teeth, regulating energy production, and more. Because the body doesn’t produce magnesium on its own, it must be obtained through diet or supplementation.

Magnesium deficiency can cause a range of symptoms, many of which are subtle or easily overlooked. Common signs include muscle cramps or twitches, low energy, poor sleep, irritability, and difficulty relaxing. In more severe cases, deficiency may affect heart rhythm, bone health, or neurological function. If you suspect you’re low in magnesium, it’s always best to consult with a healthcare professional.

Magnesium supplements help replenish low levels of this essential mineral and support a wide range of bodily functions. According to EFSA-authorised health claims, magnesium contributes to:

  • Normal muscle and nerve function
  • Normal psychological function
  • Reduction of tiredness and fatigue
  • Electrolyte balance
  • Maintenance of normal bones and teeth
  • Normal energy-yielding metabolism
  • Normal protein synthesis and cell division

Supplementing with magnesium can be especially helpful when dietary intake is insufficient or when the body’s needs are higher due to lifestyle, age, or other factors.

Always remember to consult with a medical professional before starting any new supplement regime.

Daily magnesium requirements vary by age and gender. In the UK, the recommended daily intake for adults is:

  • Men: 300mg per day
  • Women: 270mg per day

These guidelines help support healthy magnesium levels and overall well-being. Individual needs may vary depending on diet, lifestyle, and other personal factors.

The best type of magnesium depends on your individual needs and how well your body tolerates different forms. Some of the most bioavailable and well-tolerated types include:

  • Magnesium glycinate - gentle on the stomach and often preferred for relaxation and sleep
  • Magnesium malate - commonly chosen to support energy and muscle function
  • Magnesium citrate - highly absorbable and widely used for general supplementation

Multi-form blends, like our triple magnesium complex, combine these types to offer broad-spectrum support for daily magnesium needs. Whichever form you choose, it’s best to avoid magnesium oxide, which is poorly absorbed by the body.

Magnesium may support better sleep by promoting relaxation and helping regulate your body’s internal clock. It plays a role in the production of melatonin (the sleep hormone) and supports GABA activity — a neurotransmitter that calms the nervous system.

Certain forms, such as magnesium glycinate, are often preferred for sleep support due to their calming properties and gentle effect on digestion.

As always, individual results may vary, and it’s best to consult a healthcare professional if you’re considering magnesium for sleep-related concerns.

Yes, magnesium is commonly used to support healthy muscle function and may help with muscle cramps. It contributes to normal muscle function and helps regulate electrolyte balance, including calcium and potassium, which are vital for proper muscle contractions.

Low magnesium levels can increase the likelihood of cramping, particularly during exercise or at night. Supplementing with a well-absorbed form of magnesium can support proper muscle relaxation and overall muscle health.

Magnesium can cause diarrhoea or loose stools, but this side effect is most often linked to forms like magnesium oxide, which is poorly absorbed and known for its strong laxative effect.

To avoid this, choose well-tolerated forms like magnesium glycinate, malate, or citrate, and keep your intake within standard doses (generally below 400mg per day).

As always, individual tolerance varies — speak with a healthcare professional if you’re unsure.

Magnesium can be taken in the morning, evening, or split across the day — depending on your needs.

Some people prefer taking it in the evening to support relaxation and prepare for sleep, especially with forms like magnesium glycinate. Others take it in the morning with breakfast to support energy levels and daily magnesium intake.

There’s no single best time — just find a routine that fits your lifestyle and stick to it consistently.

The time it takes to notice the effects of magnesium can vary based on factors like your current magnesium levels, the form and dose, and your individual needs.

Some people may notice benefits — like improved sleep or reduced muscle tension — within a few days to a week. Others may take several weeks to experience full effects, especially if correcting a deficiency.

As always, results can vary, and consistency is key.
