The UK’s 5 Best Magnesium Supplements of 2023

Are you thinking about incorporating a magnesium supplement into your daily wellness routine? If yes, then the below guide is exactly what you need. 

Offering a whole host of health benefits including keeping your bones strong, reducing inflammation, protecting your heart health and preventing migraines, magnesium is a crucial mineral that we all need.

Despite this, almost half of the population do not get enough magnesium from their diet. 

Whether you are ready to start taking a magnesium supplement but are not sure which one to get, or you are still on the fence about taking this mineral in supplement form, read on to discover the UK’s 5 best magnesium supplements and find out more about magnesium and how it can improve your overall health and wellbeing. 

What is magnesium? 

As briefly mentioned above, magnesium is a mineral that your body needs to carry out a range of different functions and to perform at its best. 

Some of the most important roles of magnesium in the body are to control how your muscles and nerves work and to keep your blood sugar levels normal. 

Whilst you can get magnesium from certain foods and drinks such as nuts, seeds and brown rice, many people find taking a magnesium supplement more convenient. 

If you are unsure whether you are getting enough magnesium in your diet, then you can ask your doctor to carry out a blood test to find. There are also several signs that you can look out for that indicate you may be deficient in magnesium such as:

  • A loss of appetite 
  • Sleepiness and fatigue 
  • Abnormal heart rhythms 
  • Hyperexcitability 
  • Muscle spasms 
  • Shaking 
  • Vomiting and/or nausea 

It is recommended that an adult woman needs around 310 milligrams of magnesium per day and an adult male requires 320 milligrams per day. 

Certain groups are more likely to be deficient in magnesium, such as older people, those with type 2 diabetes and people with digestive problems. 

What is the best magnesium supplement?

While there are a multitude of magnesium supplements on the market, not all of these are of good quality, and these may cause unwanted side effects.
