The Ultimate Magnesium Guide: What It Does, Which One to Take, and How Much You Need

Magnesium - The mineral your body craves but probably isn’t getting enough of. You know it's important, but when you try to buy some, you're hit with an aisle full of different types—Magnesium Citrate, Glycinate, Threonate... it starts sounding like an evil wizard’s spellbook.

Relax! I'm here to break it all down for you, so you can choose the right magnesium for your needs, without feeling like you need a PhD in chemistry.

Why Magnesium Matters (Like, A LOT)

Magnesium is involved in over 300 biochemical reactions in your body. It helps with muscle function, nerve transmission, sleep, stress, digestion, and even keeping your heart ticking right. If you're feeling anxious, constipated, crampy, or just plain tired, magnesium could be your missing piece.

The problem? Most people don’t get enough. Our modern diets are magnesium-deficient, and stress, caffeine, and sugar all deplete it. So, unless you’re eating piles of leafy greens and swimming in mineral-rich spring water, supplementing is a smart move. But WHICH magnesium do you need? Let’s break it down!

The Top 6 Magnesium Forms & What They're Good For

1. Magnesium Glycinate – The Chill Pill (Best for Stress & Sleep)

• Best for: Anxiety, stress, relaxation, sleep, muscle tension

• Absorption: Excellent

• Dose: 200-400 mg/day

• Why take it? If your brain won’t shut off at night or you’re wound tighter than a rubber band, this one’s for you. Super gentle on the stomach, too!

2. Magnesium Citrate – The Go-To for Constipation (Gut Health Hero)

• Best for: Digestion, constipation, muscle cramps

• Absorption: Very good

• Dose: 200-500 mg/day (start low if you don’t want an unexpected bathroom emergency!)

• Why take it? If things aren’t “moving” like they should, magnesium citrate will help get things back on track.

3. Magnesium Malate – The Energy Booster (Muscle & Fatigue Support)

• Best for: Energy, muscle recovery, chronic fatigue

• Absorption: Very good

• Dose: 300-600 mg/day

• Why take it? This form helps with ATP production (aka cellular energy), making it great for anyone dealing with fatigue, muscle soreness, or fibromyalgia.

4. Magnesium Threonate – The Brain Booster (Cognitive & Memory Support)

• Best for: Brain fog, memory, focus, cognitive health

• Absorption: Good (crosses the blood-brain barrier!)

• Dose: 1,000-2,000 mg/day (split into two doses)

• Why take it? If you feel like your brain is running on dial-up, Magnesium Threonate helps with mental clarity, learning, and memory.

5. Magnesium Taurate – The Heart Helper (Cardiovascular Health)

• Best for: Heart health, blood pressure, relaxation

• Absorption: Excellent

• Dose: 200-400 mg/day

• Why take it? If you want to support heart health and manage blood pressure, this is your magnesium. It’s also great for relaxation without making you sleepy.

6. Magnesium Oxide – The Least Effective (But Cheap & Common)

• Best for: If you want to waste your money (kidding, sort of…)

• Absorption: Poor

• Dose: 250-500 mg/day

• Why take it? It’s cheap, but not well absorbed. You’ll find it in a lot of drugstore supplements, but most of it just passes through you without much benefit.

How Much Magnesium Do You Actually Need?

• Men: 400-420 mg/day

• Women: 310-320 mg/day

• Athletes, high-stress lifestyles, or those with chronic health issues may need more  (up to 600mg/day).
  

💡 Pro Tip: Take your magnesium at night (except for Malate, which can be energizing). If you’re new to supplementing, start with a lower dose to see how your body responds.
