## Introduction

**Magnesium** drives 300+ biochemical reactions—from energy production and muscle/nerve function to blood pressure and mood regulation. Yet many adults don’t get enough, leading to fatigue, cramps, hypertension, sleep issues, and increased stress.

At **Three Rivers Concierge Medicine in St. Louis**, we assess magnesium status and tailor nutrition and supplementation so you feel and function your best.

## 1) What Magnesium Does

- **Energy:** Required to make ATP—your cell’s energy currency.
- **Muscles & nerves:** Natural relaxant that prevents cramps and tension.
- **Bones:** About 60% of magnesium is stored in bone; it works with calcium and vitamin D.
- **Heart:** Helps maintain stable rhythm and relax blood vessels.
- **Mood & sleep:** Supports GABA signaling and melatonin production for calm and restorative sleep.

## 2) Signs of Low Magnesium

- Muscle cramps, eyelid twitches, or tension headaches
- Fatigue, weakness, or “wired-and-tired” stress
- Elevated blood pressure
- Anxiety, irritability, or trouble concentrating
- Difficulty falling or staying asleep

We use [nutritional evaluations](/node/40) and [labs](/node/24) when appropriate to identify deficiencies and guide treatment.

## 3) Food Sources You Can Rely On

- **Leafy greens:** Spinach, kale, Swiss chard
- **Nuts & seeds:** Almonds, cashews, pumpkin and sunflower seeds, chia
- **Whole grains:** Quinoa, brown rice, oats, whole wheat
- **Legumes:** Beans, lentils, chickpeas, soy
- **Fish:** Salmon, mackerel, tuna
- **Fruits:** Avocado, banana

## 4) When Supplements Help—and Which to Choose

Digestive disorders, certain medications (e.g., PPIs or diuretics), aging, and chronic stress can increase magnesium needs.

- **Magnesium glycinate:** Highly absorbable; gentle on the stomach; good for sleep and stress.
- **Magnesium citrate:** Well absorbed; mild laxative effect can help with constipation.
- **Magnesium oxide:** Lower absorption; used for specific indications.

We’ll recommend the form and dose that fit your goals and tolerance—and follow up to ensure results.

## 5) Benefits of Optimizing Magnesium

- **More energy:** Better ATP production and exercise performance.
- **Deeper sleep:** Improved sleep quality and next-day clarity.
- **Calmer mood:** Support for stress resilience and anxiety reduction.
- **Heart health:** Healthier blood pressure and rhythm stability.
- **Stronger bones:** Works with calcium and vitamin D for bone density.

## 6) Lifestyle Habits that Protect Magnesium

- **Moderate alcohol and caffeine:** Both can increase losses.
- **Manage stress:** Yoga, breathwork, and strength/cardio to reduce demand.
- **Hydrate:** Support kidney balance and electrolyte status.

## Conclusion

Magnesium touches every system—muscles, heart, brain, bones. If you’re dealing with low energy, poor sleep, tension, or high blood pressure, it’s worth checking your status and tailoring a plan that works.
