From improving sleep to easing muscle cramps, magnesium has become the latest “must-have” supplement on everyone’s bedside table. But what is the long-term impact of taking it every single day?
Dr Manish
Maheshwari, Consultant in General Medicine at Narayana Hospital, Ahmedabad, breaks down the benefits, the risks, and the reality of daily magnesium intake.
Does My Body Need Magnesium?
Magnesium is a powerhouse mineral that participates in over 300 biochemical reactions. According to Dr Maheshwari, regular intake can support several critical functions:
- Muscle and Nerve Health: It plays a key role in muscle function and nerve signalling, significantly reducing the frequency of muscle cramps.
- Mental Well-being: Daily intake can improve sleep quality and aid in managing daily stress and anxiety.
- Heart and Bones: It supports heart health and works alongside Calcium and Vitamin D to maintain bone strength and metabolic health.
Who Should Consider Supplementation?
While a balanced diet is ideal, Dr Maheshwari notes that certain groups may benefit more from a daily dose:
- Individuals with high stress levels or chronic fatigue.
- Older adults and those with diabetes.
- People with gastrointestinal disorders that hinder nutrient absorption.
- Those experiencing frequent muscle spasms or low dietary intake of leafy greens and nuts.
What Are The Disadvantages Of Magnesium?
“Supplementation should ideally be guided by a healthcare professional,” warns Dr Maheshwari. Taking high doses unnecessarily can lead to uncomfortable and sometimes serious side effects:
- Digestive Issues: The most common side effects include diarrhoea, nausea, and abdominal discomfort.
- Serious Risks: In extreme cases, very high doses can cause an irregular heartbeat or low blood pressure, particularly for those with existing kidney problems.
“It is important to avoid self-prescribing high doses,” says Dr Maheshwari, and adds “Choosing the correct form of magnesium (such as citrate, glycinate, or malate) is just as important as the dosage itself. Before starting a long-term regimen, always consult your physician to ensure it aligns with your specific health needs.”
