Why Magnesium Matters 

Magnesium is a vital mineral that plays a crucial role in over 350 enzymes in the body. It’s involved in various essential functions, like: 

  • Healthy energy production 

  • A calm nervous system 

  • Supporting a healthy heart 

  • Getting to sleep and staying asleep 

While your body doesn’t produce magnesium naturally, you can obtain it through your diet. It's worth noting that over half of the magnesium in your body is found in bone tissue, emphasizing its significance in maintaining strong and healthy bones.

Benefits of Magnesium 

  • Calmness: During times of stress, magnesium can help support nervous tension, for a sense of calm and relaxation. 

  • Heart Health: Maintaining a healthy heart and blood pressure is crucial, especially as you enter your wise years, and magnesium plays a vital role in supporting cardiovascular health. 

  • Relaxed Muscles: Magnesium supports comfortable muscles, helping to support muscle tension and relaxation. 

  • Brain and Nerves: Healthy brain and nerve function are essential for optimal cognitive performance, and you need magnesium for proper function. 

  • Deep Restful Sleep: If you struggle with sleep issues, magnesium can support restful sleep patterns, allowing you to wake up refreshed and rejuvenated. 

  • Strong Bones: Alongside other important minerals, magnesium contributes to maintaining strong and healthy bones, for healthy bone density, especially as you age. 

Should I Consider Magnesium Supplementation? 

While magnesium can be obtained from high magnesium foods such as Brazil nuts, green leafy vegetables, and lentils, certain factors can deplete magnesium levels in the body. High consumption of refined sugar and processed grains, as well as stress, caffeine, alcohol, and some types of medication can all contribute to magnesium deficiency. So, if you feel that your diet and lifestyle may not provide sufficient magnesium, supplementation can help fill any nutritional gaps. 

Different Types of Magnesium Supplements 

At HealthPost, you’ll find a wide selection of magnesium supplements available in tablet, capsule, powder and liquid form to suit any preference. For superior absorption, you may consider our BioBalance Liposomal Magnesium, known for its enhanced bioavailability. You’ll also find magnesium creams and oils that can be applied topically to support relaxation and comfort. 

Magnesium Side Effects and Considerations 

When taken as recommended, magnesium supplements are generally suitable for most individuals. However, if you have sensitive digestion, in high doses, certain forms of magnesium can lead to loose bowels. If you have a sensitive stomach, opting for a liposomal magnesium supplement can be a gentle and effective choice. 

How to choose the right magnesium

With so many options for magnesium supplements – sometimes the trickiest part can be choosing the right one for you. If you’re looking for help choosing, check out The best magnesium for your health goals.
