Supplements for Poor Sleep and Insomnia
Good sleep habits (a fixed bedtime, a dark cool room, no screens before bed and less caffeine) are the first-line answer to poor sleep. Supplements people look at include melatonin, magnesium and calming herbal formulas. Melatonin is a prescription medicine in the UK and some other countries, and rules vary by country. Ongoing insomnia deserves a medical check.

How to Choose
Pick one product and use it for two weeks. Melatonin is usually taken 30 to 60 minutes before bed, for short periods. Magnesium and herbal formulas are taken in the evening. Also try a wind-down routine, avoid caffeine after early afternoon, avoid alcohol as a sleep aid, and get morning daylight.
What Is Insomnia?
Insomnia means trouble falling asleep, staying asleep or waking too early, with daytime tiredness, poor concentration and low mood. Short-term insomnia follows stress, travel, illness or noise. Chronic insomnia lasts more than three months. Other causes include anxiety, depression, sleep apnoea, restless legs, pain, night-time urination, caffeine, alcohol and some medicines.
When to See a Doctor
See a doctor if sleep problems last more than a month, if you snore loudly and stop breathing, if you feel sleepy while driving, or if insomnia comes with low mood or anxiety. Cognitive behavioural therapy for insomnia (CBT-I) is the recommended long-term treatment.
What Supplements Can and Cannot Do
Melatonin contributes to reducing the time taken to fall asleep at doses of 1 mg or more, and it can help with jet lag. Magnesium and herbal formulas have limited evidence for sleep. Supplements do not treat sleep apnoea, depression or other causes.
Precautions and Interactions
- Do not combine CalmNite with sleeping tablets, sedatives or alcohol.
- Melatonin can cause drowsiness the next day; do not drive if you feel drowsy. Avoid it in pregnancy or breastfeeding unless a doctor agrees, and ask a doctor first if you take blood thinners, diabetes medicines or immune suppressants.
- Relaxing Pill may contain licorice, which can raise blood pressure and lower potassium.
- Magnesium: high doses loosen stools; ask a doctor if you have kidney disease.
- Not for children unless a doctor advises.
