Why Are Minerals Important for Good Health? Challenges, Sources, and Solutions

Minerals are small, some microscopic. But their impact on your health is massive. They are natural elements that our bodies need in small amounts to function properly. And they are the pillars of life. Despite being micronutrients, they have a massive impact on nearly every biological system. From energy production to brain function, bone health, and hormone regulation, they play a pivotal role. Without them, the body cannot perform at its best. Period. 

Minerals must be received through diet or supplementation. Why? The body does not produce them on its own. But due to changes in agriculture, lifestyle, and food quality, getting enough of these key nutrients is more difficult than ever. So, exactly why are minerals important? And how can we make sure we’re getting enough? Let’s dive deeper. 

Why Are Minerals Important? 

Minerals are important because they take part in virtually every bodily process. These vital nutrients act as cofactors in enzyme reactions, help send nerve signals, regulate fluid balance, support immune function, and maintain the structural integrity of our bones and tissues. Without minerals, our organs and systems would fail to operate correctly. And many issues will arise. 

Let’s break this down into several specific roles: 

1. Energy Production: Minerals like magnesium, iron, and phosphorus play critical roles in the body’s energy cycles. Magnesium activates enzymes responsible for producing ATP (adenosine triphosphate). This is the body’s primary energy molecule. 

2. Bone and Teeth Health: Calcium, phosphorus, and magnesium are essential for the formation and maintenance of strong bones and teeth. A deficiency in any of these can lead to osteoporosis, fractures, or dental issues. 

3. Nerve and Muscle Function: Sodium, potassium, calcium, and magnesium regulate nerve impulses and muscle contractions. This includes rhythmic contraction of the heart and voluntary movement. 

4. Immune System Function: Zinc and selenium support immune responses. They help everything from wound healing to defending against viruses and bacteria. A lack of these minerals weakens your body’s natural defense systems. 

5. Hormonal and Thyroid Regulation: Iodine is vital for the production of thyroid hormones, which controls metabolism. Selenium also supports thyroid function and protects it from oxidative stress. 

6. Antioxidant Protection: Minerals like selenium, manganese, and zinc act as antioxidants. They help enzymes reduce oxidative stress in the body. This protects cells from premature aging and chronic disease. 

In short, minerals are the silent multitaskers that support health at every level. 

Why Are Minerals Important for the Body? 

Minerals are important for the body because they help regulate internal processes, build tissues, and maintain homeostasis. They do a lot, from ensuring a steady heartbeat to preventing anemia or boosting your ability to fight infection. Minerals serve as building blocks and regulators of life. 

Here’s why they matter so much: 

• Your brain can’t function without them. Minerals, such as magnesium and zinc, help with neurotransmitter function, memory, and mood regulation. 

• Your muscles rely on them. Calcium and potassium allow your muscles to contract and relax properly, including your heart. 

• Your metabolism depends on them. Iodine and chromium play key roles in metabolic rate and blood sugar balance. 

• Your skin and nails need them. Deficiencies in zinc and selenium often show up as brittle nails, dry skin, or hair loss. 

Getting enough minerals ensures your body performs optimally and stays resilient against both acute illnesses and long-term chronic conditions. 

Why It’s Harder to Get Enough Minerals Today 

While the need for minerals hasn’t changed, our ability to access them has. Over the last several decades, the mineral density of food has declined. This is largely due to modern agricultural and food processing practices. 

Contributing Factors Include: 

• Over-farming: Continuous crop rotation without soil renewal depletes the land of essential minerals. 

• Synthetic Fertilizers: Common fertilizers focus on nitrogen, phosphorus, and potassium (NPK). This leaves out dozens of other trace minerals. 

• Pesticides and Herbicides: These chemicals, including glyphosate, negatively affect soil microbes that help plants absorb nutrients. 

• Water Processing: Filtered tap water removes contaminants and beneficial minerals.  

These changes have led to mineral-deficient crops affecting the nutrient quality of our diets. It even affects organic crops. 

Below is a guide to some of the most vital minerals and what they do for the body: 

Symptoms of Mineral Deficiencies 

If you’re deficient in key minerals, you may see noticeable symptoms. And they may lead to chronic health conditions over time if not addressed. 

• Magnesium Deficiency: Muscle cramps, anxiety, fatigue, irregular heartbeat 

• Zinc Deficiency: Frequent illness, skin issues, hair thinning 

• Iron Deficiency: Fatigue, brain fog, pale complexion 

• Calcium Deficiency: Bone fractures, tingling in fingers, muscle spasms 

• Potassium Deficiency: High blood pressure, constipation, muscle weakness 

• Iodine Deficiency: Hypothyroidism, goiter, cold sensitivity 

• Selenium Deficiency: Brain fog, weakened immunity, infertility 

What Affects Mineral Absorption? 

Consuming minerals isn’t enough. Your body also needs to absorb them effectively. Several lifestyle and health factors influence this: 

• Gut Health – An unhealthy gut microbiome can reduce the body’s ability to absorb minerals efficiently. 
• Diet Quality – A diet high in processed food and low in whole foods is often mineral-poor. This can further hinder absorption. 
• Stress – Chronic stress depletes minerals like magnesium and zinc faster, increasing your daily requirements. 
• Medications – Common medications like antacids, diuretics, and antibiotics can block or reduce mineral uptake. 
• Hydration – Filtered or bottled water often lacks trace minerals found in spring or well water. This impacts hydration and electrolyte balance. 

How to Optimize Mineral Intake 

Here are practical strategies to ensure you’re getting enough essential minerals each day: 

1. Prioritize Whole, Organic Foods. Choose organic and regeneratively grown produce whenever possible. These crops are more likely to contain a full spectrum of minerals. 

2. Eat Mineral-Rich Superfoods. Include foods like seaweed, leafy greens, organ meats, and pumpkin seeds in your diet. 

3. Supplement When Needed. When dietary sources fall short, consider using high-quality mineral supplements such as: 

• • Magnesium glycinate or magnesium L-threonate  (Magtein) (for relaxation and muscle health) 
  • Zinc picolinate (for immunity and skin) 
  • Trace mineral drops (for broad-spectrum coverage) 

4. Support Digestive Health. Consume fermented foods, fiber-rich meals, and probiotics to keep your gut in good shape. This will also improve nutrient absorption. 

5. Filter Water Without Stripping Minerals. Use water filters that remove toxins but preserve beneficial minerals. Or consider remineralizing your drinking water.

Magnesium on the Rise: Why This Mineral Matters More Than Ever 

Magnesium is having a moment. And for good reason. As one of the most important minerals for human health, it plays a vital role in energy production, muscle recovery, cognitive function, and stress management. Yet, despite its importance, many people still struggle to get enough through diet alone. 

To dig deeper into why magnesium is trending and what consumers need to know, we reached out to Rafea Naffa, PhD, Scientific Advisor for AIDP and an innovative bioanalytical chemist. He answered some of the most searched questions on magnesium. From how it supports the body to which forms are most effective. 

FAQs on Magnesium 

How do you tell if you need magnesium?

Many people don’t realize they are not getting enough magnesium. A 2024 global report found that about 2.4 billion people — nearly 1 in 3 worldwide — may be low in magnesium. Women tend to have lower rates of magnesium inadequacy than men.

When your body is short on magnesium, it can show up as: 

• Muscle cramps or twitches 

• Tiredness and low energy 

• Poor sleep 

• Headaches 

• Anxiety or feeling on edge 

• Trouble concentrating 

Regular blood tests don’t always determine magnesium deficiency because most of it is stored in bones and tissues. That’s why symptoms and lifestyle signs matter. 

Stress, processed foods, excess caffeine or alcohol, certain medications, and intense exercise can all drain magnesium. 

Over time, staying low in magnesium doesn’t just make you feel tired, moody, or achy, it may also increase the risk of more serious problems like high blood pressure, diabetes, heart disease, and memory decline. 

What does magnesium do for the body?

Magnesium is essential for over 300 biochemical reactions in your body. It’s involved in making energy, maintaining healthy muscles and nerves, supporting bone strength, regulating blood sugar, and balancing mood. Importantly, in the brain, it helps with learning, memory, and protecting neurons from overstimulation. Without enough magnesium, these systems struggle to function properly. 

Is it good to take magnesium every day?

Magnesium is a mineral that our bodies can’t produce and that we need every day. It’s generally safe and beneficial to take magnesium daily, as long as you stay within the recommended intake (about 310–320 mg for women and 400–420 mg for men). 

The kidneys play a key role in regulating magnesium balance by filtering and reabsorbing it to keep blood levels stable. The form of magnesium also matters where some are better absorbed and gentler on digestion than others. While common forms such as oxide, citrate, and glycinate help support overall magnesium status, they have limited ability to cross the blood–brain barrier. 

Magtein is unique because it has been shown to effectively raise magnesium levels in the brain, making it valuable for general health and especially for cognitive and neurological health. Magtein provides a specifically designed dose of elemental magnesium that delivers benefits without the short- or long-term side effects often seen with higher doses of other magnesium forms. 

If you have kidney issues or take certain medications, it’s best to check with your doctor before supplementing. 

Does magnesium help you sleep? How?

Low magnesium is associated with poor sleep and insomnia, and supplementation can often help people sleep better. Observational studies generally link higher magnesium intake with better sleep quality, though results vary by sex and population. 

A 2023 review found that magnesium supplements can sometimes help with sleep, but the results weren’t always consistent. Some studies showed clear benefits, while others did not. Researchers suggest that the type of magnesium used may make a difference, with certain forms being more helpful for sleep than others. 

Research shows magnesium can play an important role in sleep. It helps calm the brain, making it easier to relax at night, supports healthy melatonin levels to keep your natural sleep–wake rhythm on track, and relaxes tense muscles so you can rest more comfortably. 

In a 2024 study, Magtein significantly improved sleep quality, including deep sleep and next-day productivity, only after three weeks. With Magtein, you don’t necessarily sleep longer, you sleep better. 

What are the common types of magnesium? What do they do?

Not all magnesium is the same and each form has its own role. Magnesium in general supports overall health, with certain forms offering targeted benefits: citrate can aid digestion, glycinate is gentle and calming for sleep and relaxation, oxide is less absorbed but often used as a laxative, and malate can help with energy and muscle function. 

Magtein is the most bioavailable brain magnesium and shown to cross the blood–brain barrier and effectively raise magnesium levels in the brain, making it uniquely effective for memory, focus, better sleep quality, and long-term brain health — benefits beyond what other forms can provide.
