Why You Wake Up Tired — and How Magnesium + L-Theanine Can Help

Sleep 8 hours but still wake up groggy? You’re not alone.

If you’re waking up tired — even after a full night’s sleep — the problem might not be how long you sleep, but how well you sleep. Poor-quality rest leaves your brain foggy and your body sluggish. Two ingredients can make a real difference: magnesium and L-theanine.

Why Are You Still Tired?

There are a few common reasons:

• You’re not spending enough time in deep or REM sleep
• Stress keeps your brain too active at night
• You’re mildly dehydrated — even a 2% loss affects energy
• Your nervous system is overstimulated (especially after late screen time)

Magnesium: Your Night-Time Mineral

Magnesium supports your nervous system, calms muscles, and helps regulate sleep hormones. It’s essential for quality sleep — but nearly half of UK adults don’t get enough.

Low magnesium can lead to:

• Restless legs
• Muscle tightness
• Frequent waking
• Struggles falling or staying asleep

L-Theanine: Calm the Racing Mind

L-theanine promotes alpha brain waves — the same state seen in meditation. It helps relax the mind without sedation, easing you into deeper sleep and reducing mental chatter at bedtime.

When paired with magnesium, it creates a full-body calm — physical and mental.
