1. The Scale of the Sleep Problem
Sleep problems are massive in the UK, especially for people like us with ADHD and thyroid issues.
📊 The Numbers
- 26.2% of ADHD adults have clinical insomnia
- 85.2% report poor sleep quality
- 14 million people in UK may have undiagnosed sleep disorders
⚠️ NHS Reality Check
- • Waiting lists for sleep clinics are “incredibly long”
- • Lack of trained sleep therapists
- • Limited specialist resources
- • Many of us end up finding our own solutions
2. Why ADHD Makes Sleep Worse
It’s a vicious cycle. ADHD makes sleep harder, and poor sleep makes ADHD worse.
What Makes It Harder
- • Racing thoughts at bedtime
- • Can’t “switch off” mentally
- • Hyperactivity continues into evening
- • Delayed sleep-wake cycles
- • Medication side effects
The Impact
- • Worse attention during day
- • Increased impulsivity
- • Memory problems
- • Emotional regulation issues
- • Higher stress sensitivity
Key Finding: Adults with ADHD have higher stress responses and “sleep reactivity” – meaning stress affects our sleep more than neurotypical people.
3. How Thyroid Issues Affect Sleep
Hypothyroidism doesn’t directly cause insomnia, but the symptoms make sleep much harder.
Sleep Disruptions from Underactive Thyroid:
Physical:
- • Muscle and joint pain
- • Cold intolerance
- • Uncomfortable sleep positions
Mental:
- • Increased anxiety
- • More medical comorbidities
- • Overall health burden
Research Shows: People with lower thyroid hormones have longer sleep latency, shorter sleep duration, and lower sleep satisfaction.
4. The Science Behind Magnesium
Magnesium isn’t just another supplement – it’s involved in over 300 bodily processes, many affecting sleep.
🧬 How Magnesium Helps Sleep
- GABA regulation: Calms the nervous system
- Melatonin production: Natural sleep hormone
- Muscle relaxation: Reduces physical tension
- Nervous system: Activates “rest and digest” mode
- Circadian rhythms: Maintains natural sleep cycles
- Stress response: Lowers cortisol levels
🔬 Latest Research (2024)
Study: 80 adults, 21 days, magnesium L-threonate
Sleep Improvements:
- • Better deep sleep
- • Improved REM sleep
- • Increased light sleep time
Daytime Benefits:
- • More energy and productivity
- • Better mood and alertness
- • Reduced grouchiness
⏰ Effects seen in just 7-14 days!
5. Types of Magnesium (Which to Choose)
⚠️ Not all magnesium is the same! Absorption varies hugely between forms.
✅ BEST for Sleep
Magnesium Glycinate
• Gentle on stomach • High absorption • Promotes relaxation
Dosage: 200-400mg before bed
Magnesium L-Threonate
• Crosses blood-brain barrier • Cognitive benefits • Latest research
Dosage: 1000mg (as per study)
👍 Good Options
Magnesium Citrate: Good absorption, may help with constipation
Magnesium Malate: Energising, better for morning use
❌ Avoid for Sleep
Magnesium Oxide: Only 4% absorption, may cause stomach upset
Magnesium Sulphate: Epsom salts, for topical use only
6. How Much & When to Take It
💊 Dosage Guidelines
- General sleep support: 200-400mg
- Cleveland Clinic: 200mg nightly
- Mayo Clinic: 250-500mg at bedtime
- Safety limit: 350mg from supplements
⏰ Perfect Timing
- Best time: 1-2 hours before bed
- With food: Reduces stomach upset
- Consistency: Same time each night
- Split dose: Some after dinner + before bed
⚠️ Side Effects to Watch For
Common (usually mild):
- • Loose stools/diarrhoea
- • Stomach upset
- • Nausea
When to see GP:
- • Taking heart medications
- • Have kidney disease
- • Pregnant/breastfeeding
7. What to Take With Magnesium
Some nutrients work synergistically with magnesium to improve sleep even more.
🤝 Best Combinations
L-Theanine (100-200mg)
Promotes alpha brain waves, reduces cortisol, enhances GABA
Vitamin D3 (1000-4000 IU)
Supports magnesium absorption, regulates sleep-wake cycles
Ashwagandha (300-600mg)
Reduces stress markers, anxiety, and insomnia (research-proven combo)
Zinc (15-30mg)
Supports melatonin production, works synergistically
❌ Don’t Take Together
- Calcium: Competes for absorption
- High-dose iron: Reduces magnesium absorption
- High-dose zinc: Can compete (moderate doses OK)
8. Your Step-by-Step Action Plan
🚀 Getting Started (4-Week Plan)
Week 1: Start Low
200mg magnesium glycinate, 1-2 hours before bed. Track sleep in diary.
Week 2: Increase if Needed
If well-tolerated, increase to 300mg. Note any improvements.
Week 3: Add Synergistic Nutrients
Consider adding L-theanine or vitamin D3 if magnesium is helping.
Week 4: Evaluate & Adjust
Review your sleep diary. Adjust dosage or try different form if needed.
📊 What to Track

- • ADHD symptoms
- • Any side effects
My 8-Year Battle with Insomnia
After eight years of lying awake with racing thoughts, countless GP appointments, and being told to “practice better sleep hygiene,” I’ve had to become my own sleep detective.
The NHS means well, but when you have ADHD and hypothyroidism, the standard advice just doesn’t cut it. I’ve been dismissed, given basic leaflets, and put on waiting lists that seem to go nowhere.
The Nightly Reality
- • Mind racing the moment I lie down
- • ADHD brain won’t “switch off”
- • Joint aches from thyroid issues
- • Temperature regulation problems
- • Exhausted but wired feeling
Why I’m Trying Magnesium
- • Strong scientific evidence
- • Addresses multiple issues at once
- • Safe, natural approach
- • Cognitive benefits for ADHD
- • Takes control back from system
If you’re in a similar boat – exhausted, frustrated, and let down by the system – you’re not alone. Sometimes we have to become our own advocates and find evidence-based solutions ourselves.
