Magnesium, often referred to as the “unsung hero” of essential nutrients, plays a crucial role in maintaining overall well-being. From supporting muscle function to regulating blood pressure, this remarkable mineral is involved in over 300 enzyme reactions within the human body. In this comprehensive blog post, we’ll delve into the fascinating world of magnesium, exploring its functions, health benefits, dietary sources, and more.

What Is Magnesium?

Magnesium is a macromineral that our bodies require in relatively large amounts. It’s present in various tissues, including muscles, soft tissues, and bodily fluids. Approximately 25 grams of magnesium reside in the adult body, with 50–60% stored in the skeletal system. The rest contributes to critical functions throughout the body.

What Does Magnesium Do?

Magnesium wears many hats when it comes to bodily functions:

  • Muscle and Nerve Function: Magnesium ensures proper muscle contraction and nerve signalling.

  • Immune System Support: Magnesium plays a role in immune function.

Is Magnesium Good For You?

Certainly! Magnesium is essential for good health. It supports numerous bodily functions, including muscle and nerve function, bone health, and energy production. Adequate magnesium intake is linked to a lower risk of chronic diseases and can improve mood and sleep quality. However, it’s important to consume it within the recommended daily amounts.

Health Benefits of Magnesium

Bone Health

Beyond calcium, magnesium is essential for bone formation and density. Adequate magnesium intake is associated with improved bone crystal formation and a lower risk of osteoporosis.

Diabetes Management

Magnesium influences glucose control and insulin metabolism. Research suggests that it may help prevent type 2 diabetes.

Cardiovascular Health

Magnesium supports heart health by maintaining muscle function. Deficiency increases the risk of cardiovascular problems.

Migraine Prevention

Magnesium therapy may relieve headaches and reduce the frequency of migraines.

Anxiety and Mood Disorders

Low magnesium levels are linked to anxiety. Further research is needed, but it may play a 

role in mood regulation.

Specific Magnesium Benefits for Women

Reduces Premenstrual Symptoms (PMS)

Magnesium has been shown to alleviate symptoms associated with PMS, including cramps, mood swings, and bloating.

Supports Pregnancy Health

Adequate magnesium levels are crucial during pregnancy for both the mother’s and the baby’s health. It helps in reducing the risk of osteoporosis and improving foetal growth.

Menopause and Postmenopause

Magnesium can help manage menopausal symptoms, such as hot flashes and night sweats. It also supports bone health, which is particularly important as the risk of osteoporosis increases after menopause.

Can Magnesium Help With Sleep?

Yes, magnesium can help with sleep. It’s known to play a role in supporting the nervous system and activating mechanisms that quiet and calm the body, which can contribute to better sleep quality. Magnesium may also help relieve anxiety and depression, which are conditions that can interfere with sleep.

Experts recommend taking no more than 350 milligrams of magnesium to aid sleep. It’s important to consult your doctor before adding any supplements to your diet, especially if you’re considering magnesium for sleep-related issues. Foods like nuts, leafy greens, whole grains, dairy, and soy products are good dietary sources of magnesium

What Foods Contain Magnesium?

To boost your magnesium food intake, consider including these foods rich in magnesium into your diet:

Nuts and Seeds

Almonds, cashews, flaxseed, peanuts, pumpkin seeds, and chia seeds are all excellent sources of magnesium.


Foods like black beans, edamame, and lima beans are rich in magnesium.

Foods such as quinoa and shredded wheat are good sources of magnesium.

Leafy Green Vegetables

Spinach, chard, and collard greens are packed with magnesium.


Avocados, bananas, papaya, and blackberries are fruits that contain a good amount of magnesium.

Dairy Products

Nonfat milk and yoghurt are also sources of magnesium.

Dark Chocolate

Not only is it delicious, but dark chocolate is also a source of magnesium.

Additionally, some breakfast cereals and fortified foods also contain added magnesium.

Recognising the Signs of Magnesium Deficiency

Magnesium deficiency, while rare, can manifest in various ways, affecting multiple aspects of health. Here are some key warning signs to watch out for:

Muscle Cramps and Tension

Frequent muscle spasms or cramps can be a sign of low magnesium levels, as magnesium is essential for muscle function.

Mood Changes

If you’re experiencing unexplained changes in mood or increased stress, it might be related to magnesium deficiency, which plays a role in regulating the nervous system.

Insomnia: Trouble sleeping can be linked to low magnesium, which is involved in the body’s sleep-wake cycle.

Bone Health

A decrease in bone density might indicate a deficiency, as magnesium is crucial for the absorption and metabolism of calcium.


Regular occurrences of headaches or migraines could be a symptom of low magnesium, which helps regulate blood vessel function in the brain.


Persistent low energy and fatigue may be a sign of magnesium deficiency, as it’s involved in energy production at the cellular level.

Blood Sugar Imbalance

Magnesium plays a vital role in insulin secretion and glucose metabolism, so issues like insulin resistance could be related to its deficiency.

If you suspect a magnesium deficiency, it’s important to consult with a healthcare provider. They may recommend a blood test or other assessments to determine your magnesium levels and overall health.

How Much Magnesium Do I Need?

The recommended daily allowance (RDA) varies by age and sex. For instance:

  • Adults aged 19–30 need 400 mg (male) or 310 mg (female) per day.
  • During pregnancy, magnesium intake should increase by approximately 40 mg daily.

Can You Take Too Much Magnesium?

Yes, while magnesium is a crucial mineral that our bodies need for numerous biochemical reactions, it’s important to remember that, as with anything, balance is key. Consuming too much magnesium, especially in supplement form, can indeed pose risks.

Symptoms of Overdose

An overdose of magnesium can lead to what is known as hypermagnesemia. This condition is rare but serious, and can occur if your kidneys aren’t able to remove enough magnesium from your body. Symptoms can range from mild to severe and may include:

  • Nausea and vomiting
  • Irregular heartbeat
  • Low blood pressure
  • Confusion
  • Slowed breathing
  • Coma in extreme cases

Factors Influencing Magnesium Absorption

It’s also worth noting that the amount of magnesium your body absorbs can vary depending on several factors. These include the amount of magnesium in your diet, the health of your gut, and the overall balance of minerals in your body. Certain medications can also affect magnesium absorption.

Consulting a Healthcare Provider

Before starting any supplement regimen, it’s always a good idea to consult with a healthcare provider. They can provide guidance based on your individual health needs and circumstances. They can also monitor your magnesium levels if necessary to ensure they stay within a healthy range.

Avoiding Toxic Fillers such as Magnesium Stearate

Magnesium stearate is a common additive in medications and supplements, acting as a flow agent to prevent ingredients from sticking to manufacturing equipment. While it’s generally recognised as safe by the FDA, some concerns have been raised about its potential side effects and presence in products.

How to Check for Magnesium Stearate in Products

To check for magnesium stearate, read the ingredient list on product labels, particularly under the “Other Ingredients” section. It may also be listed as vegetable stearate or stearic acid.

Why Magnesium Stearate Might Be Considered Bad

Some claims suggest that magnesium stearate could suppress immune function and interfere with nutrient absorption. However, these claims are not strongly supported by scientific evidence. The main concern is that in large amounts, it may have a laxative effect and irritate the mucosal lining of the bowels.

How to Avoid Magnesium Stearate

If you prefer to avoid magnesium stearate, look for supplements that explicitly state they are free of this additive. You can also opt for products that use alternative flow agents or are produced by brands committed to not using magnesium stearate.

Potential Side Effects of Magnesium Stearate

While magnesium stearate is safe in the amounts typically used in products, some individuals may experience side effects such as:

  • Laxative effects or diarrhoea
  • Allergic reactions
  • Bowel spasms

It’s important to note that these side effects are generally associated with higher doses than what is found in supplements and medications.

Magnesium Supplementation: Forms and Dosages

Magnesium supplements come in several different forms, each with its own set of benefits and considerations. Here are some of the most common forms:

  1. Magnesium Citrate: This form is derived from citric acid and is known for its high bioavailability. It’s often recommended for those who need to improve digestion or alleviate constipation.
  2. Magnesium Oxide: This form contains a high amount of elemental magnesium but has lower bioavailability. It’s often used in over-the-counter remedies for heartburn and indigestion.
  3. Magnesium Glycinate uk: This form is highly bioavailable and less likely to cause diarrhoea. It’s often recommended for those who want to correct a deficiency without causing digestive issues.
  4. Magnesium Malate: This form is often used for people with fatigue or fibromyalgia as it’s thought to help with muscle pain and energy production.
  5. Magnesium Taurate: This form is a combination of magnesium and taurine, an amino acid. It’s often recommended for cardiovascular health.

Suggested Dosages and Considerations for Use

In the UK, the recommended dietary allowance (RDA) for magnesium varies slightly from the general guidelines. For adults, the RDA is as follows:

  • Men: 300mg per day
  • Women: 270mg per day

However, some sources suggest a slightly higher RDA of 375mg. For us at Kachina, we have seen good results when starting with a minimum dose of 600mg a day.

As always, the dosage for supplements can vary depending on the form of magnesium, so it’s important to follow the instructions on the product label. Dosage information isd a guide only and dosage is controlled at your discretion. 


In conclusion, magnesium is a vital nutrient that plays a crucial role in numerous bodily functions. From supporting muscle and nerve function to regulating blood pressure and aiding sleep, the benefits of magnesium are manifold. However, it’s important to maintain a balanced intake, as both deficiency and excess can lead to health issues.

Dietary sources such as nuts, seeds, legumes, whole grains, leafy green vegetables, fruits, and dairy products are excellent ways to incorporate magnesium into your diet. For those who require additional supplementation, Kachina offers a range of high-quality magnesium supplements.

Remember, while magnesium is essential for our well-being, it’s always important to consult with a healthcare professional before starting any new supplement regimen. Stay informed, stay healthy, and let the power of magnesium contribute to your journey towards optimal health.
