How to Choose the Best Magnesium Supplement for Your Needs
Am I deficient in magnesium? Which type of magnesium is best? How much magnesium should I take each day? As scientific research around the importance of magnesium intake and magnesium supplementation continues to develop, its popularity as a nutritional supplement is growing. However, as with many topics in health and wellness, the sheer volume of information available online can create more questions than answers.
This blog will help guide you through the fog of magnesium supplementation, breaking down the carefully constructed BioCare magnesium supplement range, explaining why magnesium is so important, outlining the different forms of magnesium used, and addressing some common questions about magnesium intake.
Why is magnesium so important?
The role magnesium plays in our health is hard to overstate. Magnesium contributes to normal psychological function, energy metabolism and the reduction of tiredness and fatigue. It is involved in over 300 enzymatic reactions in the body, and the research on the uses of magnesium supplementation is broad, looking at nervous system function, mood, sleep, electrolyte balance, protein synthesis, muscle strength and more. Magnesium is also required for energy production and the creation of DNA and RNA.
Truly a superstar mineral for everyday health!
Are you getting enough magnesium?
The daily recommended intake for magnesium is around 375mg. Magnesium deficiency can be difficult to identify, as symptoms are often non-specific. However, estimates suggest that many people are not meeting the recommended daily intake through diet alone.
Low magnesium can result from insufficient dietary intake, certain medications, underlying health conditions, or excessive physical activity. Our body’s requirements for magnesium can also be affected by stressful periods and toxic environments.
Dietary magnesium vs magnesium supplements
Food should always form the foundation of good health, and magnesium-rich foods provide valuable nutritional benefits beyond magnesium alone. However, modern farming practices and lifestyle factors can make it challenging to consistently meet magnesium requirements through food alone.
Magnesium supplements can therefore be a helpful and safe way to support intake when dietary sources are insufficient or demands are higher. Magnesium-rich foods include dark leafy greens, dark chocolate, avocado, black beans, quinoa and almonds.

What is the best time to take magnesium?
This can depend on individual needs. Generally speaking, there is no specific best time to take magnesium – however if sleep support is a priority, some may benefit from taking it in the evening. It can also be taken specifically during periods of increased stress or physical exertion.
How long should you take magnesium for?
Magnesium is safe to take daily, on an ongoing basis. To get a good idea of the impact that a magnesium supplement is having, a period of 6–12 weeks is often appropriate. The body requires time to accumulate what it needs, and our body’s requirements can vary. For tailored guidance, please contact the BioCare Clinical Nutrition team or a healthcare professional.
