How to choose the right magnesium Supplement: Experts warn against following social media trends

Magnesium is increasingly being promoted as a “miracle mineral” for sleep, anxiety, digestion, muscle recovery and overall wellness. As a result, different forms of magnesium supplements have gained popularity across social media and health markets.

However, medical experts caution that many people are taking supplements without understanding which form best suits their health needs.

Different forms of magnesium and their uses

According to internal medicine specialists, each magnesium compound behaves differently in the body and serves distinct purposes.

• Magnesium glycinate is often recommended for relaxation, stress and sleep support. It is generally well absorbed and considered gentle on the stomach, making it suitable for individuals with anxiety or sleep disturbances.
• Magnesium threonate is being studied for its potential effects on brain health and cognitive function. Early research suggests it may cross the blood-brain barrier more effectively, although evidence is still developing.
• Magnesium citrate is commonly used for digestive health, particularly for relieving constipation, as it draws water into the intestines. However, excessive use may lead to diarrhoea and dehydration.
• Magnesium malate is associated with energy production and muscle function, and is often used by individuals experiencing fatigue or muscle soreness.
• Magnesium taurate is linked to cardiovascular health, with taurine potentially supporting heart rhythm and blood pressure regulation.
• Magnesium oxide is widely available and inexpensive but is less efficiently absorbed. It is mainly used as an antacid or laxative rather than for correcting deficiency.

Risks of overuse and self-medication

Experts warn that excessive magnesium intake, particularly through supplements, can cause side effects such as diarrhoea, abdominal cramps, dizziness, and low blood pressure.

People with kidney disease are at higher risk, as the body may struggle to eliminate excess magnesium, potentially leading to dangerous accumulation.

Magnesium can also interfere with certain medications, including antibiotics, thyroid treatments, osteoporosis drugs and some heart medicines, making medical guidance important before use.

Importance of diet and balanced intake

Health professionals emphasise that most people can meet their magnesium needs through a balanced diet. Foods such as nuts, seeds, legumes, leafy greens and whole grains naturally provide magnesium.

Supplements should ideally be used only when necessary and selected based on individual health conditions, symptoms and professional advice, rather than social media trends.
