If you’ve ever wandered through the supplement aisle and felt overwhelmed by the different types of magnesium - glycinate, citrate, oxide, malate - you’re not alone. Magnesium is one of the most essential minerals in the body, yet one of the most misunderstood.

It plays a key role in hundreds of biological processes, from regulating stress and hormones to supporting energy, sleep, and digestion. But here’s the thing: not all magnesium supplements are created equal. Different types serve different purposes - and knowing which one is right for you can make a world of difference.

Let’s break it down in a way that’s simple, clear, and actually helpful.

Why Magnesium Matters (Especially for Women 35+)

Magnesium supports more than 300 biochemical reactions in the body. It helps balance hormones, reduce PMS symptoms, calm the nervous system, aid in muscle recovery, regulate blood sugar, and promote restful sleep.

Between hormone fluctuations, stress, and nutrient-depleting medications (like birth control or antacids), many women over 35 are unknowingly deficient.

Common symptoms of magnesium deficiency include (1):

• Fatigue or brain fog
  

• Muscle cramps or restless legs
  

• Headaches or migraines
  

• Insomnia or light sleep
  

• Anxiety or mood swings
  

• Constipation or bloating
  
  

The Different Types of Magnesium - Explained

Here’s a quick guide to the most popular forms and their specific benefits:

1. Magnesium Glycinate

Gentle on digestion and good for stress, anxiety, blood sugar balance and sleep support. It binds with glycine, a calming amino acid, making it perfect for evening use.

2. Magnesium Citrate

Well absorbed and effective for digestion. Often used for constipation relief. Start with a small dose as it can cause loose stools in some people.

3. Magnesium Threonate

Known for its ability to cross the blood-brain barrier. Supports cognitive function, mental clarity, and may reduce brain fog. Great for midlife focus support.

4. Magnesium Malate

Supports energy production and muscle recovery. Often recommended for those with fatigue, fibromyalgia, or chronic pain.

5. Magnesium Oxide

Contains a high amount of elemental magnesium. Often considered to be poorly absorbed, however it appears that this could be a positive if you’re trying to use mg to treat something further afield i.e. migraine, with many clinical trials for mg and migraine showing a positive effect.

How to Choose the Right One for You

Think of magnesium like a toolbox - you want the right tool for the job.

• Struggling with sleep or stress? Try magnesium glycinate before bed.
  

• Need digestive support? Magnesium citrate may help get things moving.
  

• Battling brain fog? Magnesium oxide can sharpen your focus.
  

• Dealing with fatigue or muscle tension? Magnesium malate is a great option.
  
  

When starting any new supplement, begin with a low dose and increase slowly. Always check with your healthcare provider - especially if you’re taking medication or managing a health condition. For whole body magnesium restoration, consider a high-quality magnesium complex, used in combination with topical magnesium and magnesium-rich foods.

Final Thoughts

Magnesium may not be flashy, but it’s one of the most powerful minerals in your wellness toolkit. Choosing the right form for your body can support better sleep, calmer moods, balanced hormones, and a stronger, more resilient you.

Listen to your body - it’s smarter than you think.
