Health Benefits & Sources
Why You Need It
- Better Sleep: Helps regulate melatonin and GABA, the brain's 'shut-off' switch.
- Muscle Recovery: Prevents cramps and spasms by balancing calcium (which contracts muscles) and magnesium (which relaxes them).
- Stress Reduction: Supports the hypothalamic-pituitary-adrenal (HPA) axis, keeping cortisol levels in check.
- Heart Health: Vital for maintaining a steady heartbeat and regulating blood pressure.
Deep Dive
Magnesium acts as a natural calcium blocker to help muscles relax after contracting. When you are deficient, your muscles may stay tense, leading to cramps or twitches. It also plays a massive role in energy metabolism by helping convert food into ATP (your body's energy currency). Without adequate magnesium, your body literally struggles to produce energy, leading to that 'draggy' feeling.
Natural Food Sources
Getting magnesium from food is superior because food sources are packed with co-factors that help absorption.
| Food | Amount | % Daily Value (DV) |
|---|---|---|
| Pumpkin Seeds | 1oz (approx. 1/4 cup) | 37% |
| Spinach (Cooked) | 1 cup | 24% |
| Black Beans | 1/2 cup | 23% |
| Dark Chocolate (70%+) | 1oz | 15% |
| Avocado | 1 medium | 10% |
Supplementation
If you struggle to eat leafy greens or nuts daily, a supplement may help. Magnesium Glycinate is highly absorbable and gentle on the stomach (best for sleep and anxiety). Magnesium Citrate is often used for constipation relief. Start with 200-400mg daily, ideally taken with food.

Safety & Side Effects
Magnesium is generally very safe. However, people with kidney disease cannot excrete excess magnesium properly and should only take it under medical supervision. High doses (over 350mg from supplements) can cause digestive upset (loose stools), nausea, or cramping. It can interact with certain antibiotics and diuretics. Consult a doctor if you have heart or kidney issues.
