Magnesium is one of the most essential minerals in your body. Yet, many Australians don't get enough of it. This can affect how we feel, how much energy we have, and even how well we sleep. Luckily, magnesium dietary supplement benefits are supported by science and research, especially when it comes to boosting energy, mood, and overall wellbeing.
In this article, we’ll explain how magnesium works in the body, what happens when you're low on it, and how magnesium supplements can help—especially for growing kids, busy adults, and older Australians.
What Is Magnesium and Why Is It Important?
Magnesium is a mineral found in your bones, muscles, and blood. Your body needs it to make energy, build strong bones, help your muscles relax, and keep your heart beating normally ( NHMRC, Nutrient Reference Values for Australia and New Zealand, 2023).
What Are the Benefits of Magnesium?
Here are some key magnesium dietary supplement benefits backed by Australian research: 
What Happens to Your Body When You Start Taking Magnesium?
According to Department of Health and Aged Care Australia in the Nutrient Reference Guide 2022, many people report feeling calmer and more energetic when they start taking magnesium regularly. Here’s what happens:
- Muscles feel less tight or sore
- You may sleep better at night
- Digestion may improve
- Feeling less anxious or overwhelmed
Is It Good to Take Magnesium Every Day?
Yes, it’s safe for most people to take magnesium supplements every day, especially if their diet is low in magnesium-rich foods like leafy greens, nuts, and whole grains.
The NHMRC recommends daily magnesium intake of:
- 310–320 mg for women
- 400–420 mg for men
Just make sure you don’t go over the recommended dose, unless advised by your doctor.
Important Word Explained:
Recommended Dietary Intake (RDI) – The average daily amount of a nutrient needed to stay healthy.

- Trouble sleeping
- Feeling stressed or moody
- Headaches or migraines
- Irregular heartbeat
If you're experiencing these, it may be time to look into magnesium dietary supplement benefits.

If you're taking any other medications or have kidney problems, speak to your doctor before starting a supplement.
