Best Magnesium Supplements UK 2022 Reviews

Experts say that we do not eat enough magnesium-rich foods. This is a vital mineral for our health and the deficiency could put us at risk of many diseases.

This is why it’s a good idea to consider taking supplements regularly.  These supplements are available in a variety of forms. Here at Nature’s Cure Zone; we have the listed top 9 forms of best magnesium supplements for the UK customers according to your need.

Magnesium Supplements

As kids, we have often been told to take our multivitamin and to eat green leafy vegetables because of the many good things it can do for our body. The emphasis then was on vitamin intake, not much on the minerals, and certainly not on magnesium.

One of the minerals that are gaining notice in the last few years is magnesium. It is one of the most abundant and most common elements of the earth. In the human body, it is the hardest working mineral.

It is included in the fundamental base of almost all of our body processes. It is vital to energy production which makes the human body get up and go, regulating heartbeat rhythms,  metabolism, the transmission of nerve impulses, muscle contractions, and for the formation of proper bone density.

With all it’s abundance and commonness, a whopping 80% of us are sadly magnesium-deficient. This may be attributed to malabsorption brought by digestive disorders,  malabsorption and non-utilization of it brought by digestive tract damages borne out of antibiotic and prescription drug usage, and soil nutrient run down which largely diminishes the amount of it in the plants that we consume.

We can get it from many foods but due to poor absorption and depleted soil nutrition, Mg12 levels can be low in your body. This is why many of us are taking supplements. So what are the best magnesium supplements to take? There are many kinds of these supplements. You should know which one is right for you.

Why Should You Take It?

Magnesium is one of the seven major minerals that are vital to the functions of our body. Deficiency in this mineral could lead to cell malfunction and other ailments:

  • The tendency of blood to clot or thicken even without cuts, wounds, or haemorrhage. This thickening is particularly dangerous if it occurs in the blood vessels as it would increase the risk of heart attack or stroke.
  • Abnormal contractions of the heart and blood-vessel muscle tissues. Fight-or-flight reactions during dangerous situations do not work normally.
  • Muscles tend to feel more pain, burning, and unnecessary twitching.
  • Abnormal cholesterol production.
  • Insufficient energy for work, and other activities, and feeling tired, lethargic, and stressed most of the time.
  • Susceptibility to free radical damage, as there is an insufficient natural antioxidant protecting the body molecules.
  • Heart diseases, and Type 2 Diabetes which is brought by the improper processing of glucose.
  • Stiffening, and plaque buildup in arteries brought by too much calcium.

Taking supplements can be the answer to arresting magnesium deficiency. But with many different types of Mg12 supplements in the market, the question would be what would be best for you?

It needs to be bound to something else to be stable. Hence, the differences of the many products primarily come from the molecule it’s bonded to, and not magnesium itself. There are two things to consider when buying them:

  • The function of the bonding agents ( oxide, glycinate, citrate ).
  • Absorption or bioavailability, this is the fraction or ratio of the magnesium which entered the systemic circulation (blood ) thus having an effect.

Are There Any Concerns?

Considering that Magnesium is one of the seven major minerals that the body needs are enough reason to take supplements. Thinking that all requirements can be sourced from diet alone is poor planning, especially since crops are planted in soil that is already depleted with essential nutrients, to begin with. However, too much intake of one mineral may lead to a deficiency in another, and excessive magnesium can, in turn, cause a deficiency in calcium.

Overdosing on supplements which could cause toxicity is rare, but not impossible. This, however, is not a risk to most people.

A more common side effect of too much of it is its laxative effect, overstimulation of bowels than cause excessive urination,  sometimes nausea, and abdominal cramping.

An overdose may be experienced by people with kidney problems. The manifestation of poisonous magnesium levels can vary from vomiting,  upset stomach, and diarrhoea,  to more serious episodes of confusion, slowed heart rate and dangerously low blood pressure. Very serious overdoses can lead to irregular breathing, coma, irregular heartbeat and even death.

As with other drugs and supplements, these supplements can interact with other drugs a person may be taking.  The intake that is too close to a dose of some antibiotics, particularly ciprofloxacin and moxifloxacin, may interfere with how the body absorbs the medicine. It can also interfere with osteoporosis drugs if the intake is done too close together. Thyroid medications are also affected by it. It can also bring bad side effects from blood pressure medications in the same way that it can magnify the potency of some diabetes medicines.

On the other hand, supplements are always a good choice in arresting magnesium deficiency in the body. Each form is absorbed differently from the other, and are suited for different situations. Understanding how these forms will function in our body will help us tremendously in choosing the most appropriate supplement for us. Several more studies on the effect of supplements on pregnant and breastfeeding women must also be considered.


There are more than 300 body processes which are dependent on magnesium for their proper function.  Indeed, its deficiency is a major cause of some diseases and chronic illnesses. Deficiency of this mineral is more often than not unnoticed or overlooked.

It is because of this reason that people should consider adding magnesium supplements to their diet. These supplements present the option of achieving optimal levels of it vs the hit or miss of the ordinary diet. Each type of supplements offers different benefits, and are made to be appropriate for different circumstances.

Consulting a health professional on how to incorporate these supplements into the diet is a good step to achieving optimal health, and ensuring that the body reaps the benefits of sufficient magnesium intake.
