The link between sleep and muscle health

Sleep and muscle health are intricately connected. As we rest each night, our bodies are hard at work replenishing energy stores, repairing tissues and facilitating healthy muscle function. Whether you train hard, keep movement light and leisurely or sit at a desk all day, it’s worth understanding the relationship between sleep and muscle health. The targeted nutrients and herbal medicines in Herbs of Gold magnesium supplements for sleep may help support both.

Why sleep matters for muscle recovery

Sleep is way more than rest and downtime. Growth hormone is one of our key repair hormones, and it’s released by the body in pulses during deep, slow-wave sleep. It’s during this stage, via this hormone, that a majority of our tissue repair and protein synthesis in muscle occurs. Sleep restriction research has shown that when sleep is deficient or disturbed, especially over time, this ‘repair window’ narrows, which may result in reduced protein synthesis in the muscle and slower overall recovery[1]. Further, cortisol, the body's primary stress hormone, follows its own rhythm across the night, working in a complex relationship with growth hormone[2]. When sleep is cut short, disturbed or fragmented, this hormonal balance can tip toward a less favourable state for optimal overnight repair.

For everyone at every age, muscle health matters. Whether you're a competitive athlete, a ‘weekend warrior’, on your feet all day, working in a sedentary job or managing an illness, the quality of your recovery, which happens during deep sleep, dictates your muscle health over time - not just after one challenging workout or one night of tossing and turning. Magnesium - an essential mineral – is known to play important roles in the maintenance of healthy muscle contraction and helping our cells to convert food into usable energy units.

Magnesium supplements for sleep and muscle function

Magnesium is involved in over 600 known processes in the body, including those that support and maintain muscle function, nervous system function and healthy stress responses[3]. This means that magnesium supplements support muscle health and general wellbeing. High stress levels or physical activity also increase requirements for magnesium. This is just one of the reasons why magnesium-focused evening supplements are a common recommendation among naturopaths and nutritionists.

Helpful herbs

Preparations from plants have a long history of traditional use for improving sleep in Western herbal medicine. For example, Passionflower is traditionally used to help calm the mind, decrease restlessness and support refreshing sleep.  Another herb, California poppy, has a long history of traditional use in supporting the body's evening wind-down, and is often paired with Passionflower.[4] Herbal ingredients like these can be combined with magnesium to support a night-time routine.

Sleep and recovery supplements

If you're thinking about trying a sleep and recovery supplement, the first step is to understand what's in the formula, and how each ingredient is traditionally used. Herbs of Gold formulations are developed by a team of highly qualified naturopaths, herbalists and nutritionists who combine traditional wisdom with the latest research. Within the Herbs of Gold sleep range, two magnesium-based options have been thoughtfully formulated with this approach.

Magnesium Night combines Passionflower, California poppy and magnesium in a highly absorbable glycinate form. Magnesium Night Plus offers a higher-strength powder for those needing extra support. It supplies magnesium in both amino acid chelate and citrate forms alongside glutamine and calcium for added nutritional support. Passionflower and California poppy also feature in this delicious citrus-berry flavoured formulation.

Simple habits to support sleep and muscle recovery

Even the best sleep supplement requires a foundation of health everyday (or every night!) habits to work best. Small, consistent changes to your evening routine can make a significant difference in how well you sleep, and how well your muscles recover overnight.

Some of the best ways to support your sleep include:

  • Keeping a consistent sleep and wake time (even on weekends!)
  • Reducing your screen time and bright lights in the hours before bed
  • Staying hydrated throughout the day
  • Including magnesium-rich foods in your daily diet (leafy greens, nuts and seeds are great choices)
  • Winding down with gentle stretching or breathing exercises before your head hits the pillow
  • Avoiding intense exercise or caffeine close to bedtime

No single ingredient in a supplement formulation can fully offset a consistently poor sleep routine or stressful lifestyle, and these habits work alongside any supplement you might choose as a holistic health strategy.

Final thoughts

Sleep and muscle health are closely linked, and magnesium is one of the nutrients that has a key role in nervous system health and muscle function. If you're ready to build a better evening routine, support your sleep with traditional herbs and optimise your muscle health, consider adding a magnesium supplement or sleep support supplement from Herbs of Gold to your nightly routine, and consult with your health professional if symptoms persist.
