Struggling With Stress, Soreness or Sleep Issues? Meet Magnesium!
Whether you're navigating the demands of daily life, recovering from intense workouts, or adjusting to the sleepless nights of new parenthood, your body and mind need all the support they can get. One essential nutrient that often flies under the radar - but plays a powerful role in how we feel - is magnesium.
Magnesium is involved in hundreds of processes in the body, from managing stress and easing muscle tension to supporting restful sleep. For many of us, especially during times of physical or emotional stress, our magnesium levels can take a hit - leading to fatigue, poor recovery and disrupted sleep.
If stress, poor sleep or slow recovery are holding you back, magnesium could be the missing link in your wellness routine.
What is Magnesium?
Magnesium is an essential mineral that supports a wide range of essential functions in the body - from muscle and nerve function to regulating blood pressure, balancing blood sugar levels and maintaining healthy bones. In fact, every single cell in your body needs magnesium to function properly. Despite its importance, magnesium deficiency is surprisingly common in Australia, with some estimates suggesting that up to 80% of adults may not be meeting their daily needs.
Signs of magnesium deficiency include:
- Fatigue and weakness
- Muscle cramping and twitching
- Sleep disturbances
- Headaches
- Abnormal heart rhythms
Your body’s magnesium requirements can also increase during certain life stages or periods of stress. Pregnancy and the postpartum period are key examples of when nutrient stores are depleted and the body is under additional strain from hormonal shifts, disrupted sleep and physical recovery. Supporting your body with adequate magnesium during these times can make a noticeable difference in how you feel - both physically and emotionally. Because magnesium is involved in so many vital processes, even a mild deficiency can lead to noticeable symptoms, such as stress, fatigue, muscle cramping and poor sleep quality. Good sources of magnesium include leafy green vegetables, nuts and seeds, seafood and dark chocolate. However, when dietary intake is insufficient or requirements are higher, supplementation should be considered.

Magnesium & Stress
Magnesium plays a crucial role in regulating the body’s stress response and promoting a sense of calm. It helps soothe the nervous system, support healthy cortisol levels and contributes to a balanced mood by influencing key neurotransmitters in the brain, calming the excitatory ones and boosting the inhibitory ones like GABA. This balance helps reduce feelings of stress and anxiety.
Research also shows that magnesium offers neuroprotective benefits, helping to shield the nervous system during times of mental and physical strain. In essence, magnesium acts as a buffer against stress, supporting your body’s ability to cope and recover.
However, it’s important to note that stress itself can deplete magnesium levels. When the body is under pressure - whether from emotional tension, physical exhaustion or disrupted sleep - magnesium is used up much more quickly. This creates a cycle of depletion, especially common during periods like menstruation, pregnancy, postpartum or menopause, when both physical recovery and emotional stress are at their peak.
That’s why it's so important to nourish your body with magnesium rich foods and supplements, especially during stressful seasons when your body needs extra support to restore balance.

Magnesium & Muscle Recovery
Magnesium plays a key role in muscle recovery and overall muscle health. It regulates muscle contraction and relaxation, supports protein synthesis and helps reduce soreness after activity. By aiding in the repair and growth of muscle tissue, magnesium also helps prevent common issues like cramps, spasms and muscular fatigue.
Magnesium for Postpartum
But magnesium isn’t just important for post gym recovery - it’s equally essential during periods like postpartum. After childbirth, many new mums experience muscle aches, tension and soreness, whether from labour itself or from the daily demands of caring for a newborn (let’s be honest - holding and feeding a baby for hours each day is its own kind of workout!)
Magnesium supports deep muscle relaxation and helps soothe those everyday aches and strains, making it a powerful nutrient for physical recovery in the weeks and months after birth. It also helps calm inflammation by reducing the production of inflammatory molecules - supporting a smoother, more comfortable recovery process.
Magnesium & Sleep
One of the most well-known and appreciated benefits of magnesium is its ability to support deep, restorative sleep. It works in several key ways - helping to regulate cortisol levels, calm the nervous system, promote the release of GABA (a calming neurotransmitter), and support the production of melatonin, the hormone that governs our sleep-wake cycle. Studies have linked healthy magnesium levels with better sleep quality, longer sleep duration, and reduced daytime fatigue.
Magnesium may also ease symptoms of restless legs syndrome, a condition that causes uncomfortable sensations in the legs at night and can make falling or staying asleep a challenge. This is likely due to magnesium’s role in muscle relaxation, nerve function, and electrolyte balance - all of which are essential for restful sleep.
This support is especially important during the postpartum period, when sleep is in short supply but more valuable than ever. Although newborns bring unavoidable nighttime wakeups, magnesium can help new mums wind down more easily, fall asleep faster between feeds, and gently rebalance their sleep-wake cycles - so they can make the most of every minute of rest!
