Signs You're Magnesium Deficient (And How to Fix It)

Why Magnesium Matters More Than You Think

Magnesium is involved in over 300 biochemical reactions in the body — from energy production and muscle function to sleep regulation and stress response. Yet studies suggest that up to 50% of Americans don't get enough magnesium from their diet alone.

The problem? Magnesium deficiency often shows up as vague, everyday symptoms that are easy to dismiss. Here's what to look for.

7 Signs You May Be Magnesium Deficient

1. You're Always Tired

Magnesium plays a key role in converting food into energy at the cellular level. Low magnesium means your cells can't produce energy efficiently — leaving you feeling drained even after a full night's sleep.

2. You Can't Sleep Well

Magnesium regulates melatonin and GABA — two key neurotransmitters that help your brain wind down at night. Without enough magnesium, your nervous system stays in a heightened state, making it hard to fall or stay asleep.

3. You Feel Anxious or On Edge

Magnesium acts as a natural "brake" on the nervous system. When levels are low, stress hormones like cortisol can run unchecked — contributing to feelings of anxiety, irritability, and overwhelm.

4. You Get Muscle Cramps or Twitches

Magnesium and calcium work together to control muscle contractions. Low magnesium means muscles can't fully relax — leading to cramps, spasms, or that annoying eye twitch that won't go away.

5. You Have Frequent Headaches

Research shows that people who suffer from migraines often have lower magnesium levels. Magnesium helps regulate blood vessel tone and neurotransmitter activity — both of which play a role in headache onset.

6. Your Mood Is Low

Magnesium is essential for serotonin production — the neurotransmitter most associated with mood and wellbeing. Low magnesium has been linked to higher rates of depression and mood instability.

7. You're Constipated

Magnesium draws water into the intestines and helps relax the muscles of the digestive tract. It's one of the reasons magnesium supplements are often recommended for regularity.

Who Is Most at Risk?

Certain groups are more likely to be deficient:

• People who drink alcohol regularly
• Those with type 2 diabetes or insulin resistance
• People under chronic stress
• Those who eat a highly processed diet
• Older adults (absorption decreases with age)
• People taking certain medications (like diuretics or PPIs)

How to Fix It: Food First

The best dietary sources of magnesium include:

• Dark leafy greens (spinach, Swiss chard)
• Pumpkin seeds and almonds
• Black beans and lentils
• Dark chocolate (70%+)
• Avocado and bananas

The challenge is that modern soil depletion means even "healthy" foods contain less magnesium than they used to. That's where supplementation becomes valuable.

Why Magnesium Glycinate Is the Best Form

Not all magnesium supplements are created equal. Magnesium oxide (the cheapest form) is poorly absorbed and often causes digestive upset. Magnesium glycinate — magnesium bound to the amino acid glycine — is one of the most bioavailable and gentle forms available.

Glycine itself has calming properties, making magnesium glycinate particularly effective for sleep and stress support.

Our Magnesium Glycinate Gummies deliver a therapeutic dose in a delicious, easy-to-take format — no horse pills required.

How Much Do You Need?

The recommended dietary allowance (RDA) for magnesium is:

• Women: 310–320 mg/day
• Men: 400–420 mg/day
• Pregnant women: 350–360 mg/day

Most people benefit from supplementing with 200–400 mg of elemental magnesium daily, ideally taken in the evening to support sleep.

The Bottom Line

Magnesium deficiency is common, underdiagnosed, and surprisingly easy to address. If you're dealing with poor sleep, low energy, muscle cramps, or chronic stress, it's worth taking a closer look at your magnesium intake.

Start with food, supplement smartly, and give your body the mineral it needs to function at its best.
