You may be wondering why everyone is talking about magnesium - so we are here to walk you through this mineral and the best magnesium supplements to help you on your way. Taking the spotlight in the wellness world, magnesium quietly plays a pivotal role in over 300 bodily functions - from powering your cells to ensuring your heart beats in a healthy rhythm. This is one of the best supplements and a multitasker you can't afford to ignore. However, it’s best to check with your doctor if you take any medication before starting any supplements.

It's alarming but true—most of us are running on low levels of magnesium and vitamin D. Why? Our modern diets are often lacking in magnesium-rich foods. Plus, the best vitamin D supplements are flying off the shelves as more and more people recognise its importance as, unfortunately, the UK doesn't get consistent sun year-round. For women especially, magnesium is a game-changer. It helps manage symptoms and changes that occur during menopause, such as hot flashes and mood swings, making it one of the best supplements for perimenopause. Plus, it may help with period pain, too.

Buyer's guide: Best magnesium supplements

We spoke to naturopath and holistic health expert Kate Booker for her suggestions on taking magnesium. We also had the opportunity to ask Rob Underwood, Product Development Manager at Love Life Supplements, some frequently asked questions to clearly understand magnesium's effect on the body and the different types and what they do.

The basics of magnesium with Kate Booker

If you are feeling a bit overwhelmed with all this information, here is naturopath Kate's simple guide to understanding this vital mineral.

"Magnesium is a very important mineral that’s needed for well over 300 enzymatic reactions in the body", explains Kate. "Most people are deficient as our soils have been depleted over the years, and stress increases magnesium excretion, too. Muscle cramps, anxiety, poor sleep and, low energy, headaches, or palpitations could all be signs you’re deficient. Poor diet, absorption issues (in the gut) and alcoholism can cause a further deficiency."

Why do we need magnesium?

To put it simply, this is why magnesium is so important for our overall health:

It’s vital for energy production 
DNA repair
Muscle relaxation
Regulation of sex hormones
Protects against stress
Helps to lower blood pressure
Supports tooth enamel

How do you know you are magnesium deficient?

Kate tells us some telltale signs that you could be experiencing a magnesium deficiency: fatigue, migraines, muscle cramps, stress/anxiety, insomnia, and high blood pressure. It can help women improve PCOS, PMS and period pain symptoms. It may be worth trying magnesium if you have any of these symptoms. However, if you are experiencing these symptoms, it’s best to check with a health professional to find the root cause and to check if supplements will interact with any medication you are taking.

What are ionic magnesium drops?

"Some prefer an ionic form of magnesium that comes in liquid form. Magnesium does not need to be broken down in the stomach; it also allows for gradual absorption of the mineral in the diet for those with a sensitive stomach. Taking too much magnesium can have a laxative effect."

A young woman pours magnesium nutritional supplement into a glass of water.

If you want a more in-depth understanding of this mineral, Rob is here to break magnesium down even further.

What is the role of magnesium in the body?

As Kate mentioned, this mineral supports energy production, muscle contractions and relaxation, bone health, heart health, blood glucose/ sugar control, blood pressure regulation and DNA maintenance. Here is Rob's explanation of magnesium's role in the body:

"Magnesium is an essential micronutrient that is involved in over 300 bodily processes. One of magnesium's main roles is in the production of Adenosine Triphosphate (ATP), the energy currency of every cell in the body. Magnesium is also involved in the proper functioning of nerves and their communication. It also helps to regulate muscle contractions by blocking calcium moving into the cell (which causes a contraction).

"It is important for the development and maintenance of bone health as it helps to regulate the calcium balance and the activity of the parathyroid gland, which in itself plays a huge role in maintaining calcium homeostasis (equilibrium) within the body.

"Magnesium is also critical for heart health as it helps to transport calcium and potassium molecules across cell membranes within the heart, leading to a healthy cardiac rhythm. It is required to control blood sugar levels, and it does this by helping to regulate the hormone insulin, which is the body’s main controller of blood glucose.

"Something less known about magnesium is its ability to help manage blood pressure; it accomplished this by increasing nitric oxide and relaxing blood vessels. Lastly, magnesium plays an important role in the replication and repair of DNA."

What are the most common sources of magnesium in food?

Green leafy vegetables - spinach and kale.

Grains – oats, quinoa, barley

Nuts and seeds – flax, chia, almonds

Many fruits – avocado, bananas, kiwi, papaya

Dark chocolate

Super food grains

What are the different types of magnesium, and what areas do they help with?

Rob says there are more than a dozen forms of magnesium – these are some of the most common forms and what they can do to support you. These forms are also ones in LLS's Magnesium Complex Advanced supplement.

Magnesium Orotate - Includes orotic acid, a natural substance involved in your body’s construction of genetic material, including DNA.

Magnesium Taurate - Contains the amino acid taurine. Adequate intake of taurine and magnesium may play a role in regulating blood sugar levels.

Magnesium Lactate -The salt is formed when magnesium binds with lactic acid. It is easily absorbed and gentle on your digestive system. Supports the function of the heart, nervous system, and digestive system.

Magnesium Malate - A compound of Magnesium and Malic Acid. It can support protein synthesis, muscle function, nerve function and bone health.

Magnesium Glycinate - Formed by combining elemental magnesium with the amino acid glycine, making it highly stable. It can combat fatigue and support muscle function, nerve health and bone maintenance.

Magnesium Citrate - Magnesium which is bound with citric acid. An optimally absorbed form of magnesium for energy, mental wellbeing and bone and muscle support.

Sucrosomial Magnesium - The application of Sucrosomial Technology protects the magnesium in the gastric environment, so it is absorbed more easily in the intestines.

What is the suggested dosage of magnesium?

The magnesium RDA is 375mg, and the Magnesium Complex Advanced provides 88 per cent of that or 329 mg per serving.
