What nutrients help you sleep better?

Key sleep-promoting nutrients include melatonin, the sleep hormone that regulates your body clock; tryptophan, an amino acid the body uses to produce serotonin and melatonin; magnesium, which relaxes muscles and calms the nervous system; calcium, which supports melatonin production and regulates muscle contractions; and antioxidants, which reduce inflammation and oxidative stress that can interfere with restful sleep.

What are the best foods to eat before bed to help you sleep?

Foods that can help promote sleep include almonds (magnesium and melatonin), turkey (tryptophan), chamomile tea (antioxidants that reduce anxiety), kiwi (serotonin and antioxidants that improve sleep onset), cherries or tart cherry juice (melatonin), bananas (magnesium, potassium, and vitamin B6), oats (complex carbs and melatonin), warm milk or fortified alternatives (calcium and tryptophan), leafy greens such as spinach and kale (magnesium and calcium), and fatty fish such as salmon or mackerel (omega-3s and vitamin D that regulate serotonin).

What foods and drinks should you avoid before bed?

Avoid caffeine from coffee, cola, energy drinks, and chocolate as it stimulates the nervous system and delays melatonin production. Alcohol can cause initial drowsiness but disrupts deep sleep cycles. Heavy or spicy meals can cause heartburn or indigestion. Sugary snacks cause blood sugar spikes and crashes that disturb sleep. Healthier alternatives include herbal teas, sparkling water, light meals with lean proteins and vegetables, or a small handful of nuts or a banana.

How long before bed should you stop eating?

Aim to eat your last meal 2 to 3 hours before bed. Eating too close to bedtime, especially high-fat, sugary, or spicy food, can lead to discomfort or indigestion and prevent sleep-enhancing nutrients from working effectively. A light evening meal around 6:30 to 7pm, followed by a sleep-supporting drink such as chamomile tea or warm milk around 8:30pm, supports a good sleep routine.

Lots of healthy food is laid out on a wooden table, including bowls of different nuts, fruit, vegetables, dark chocolate and brown bread.

Food can fuel sleep

Q: Can what you eat affect how well you sleep?

Yes. Your diet directly influences the production of key sleep hormones like melatonin and serotonin, as well as minerals such as magnesium and calcium that help the body relax. Some foods encourage deeper, more restorative sleep, while others — including caffeine, alcohol, and heavy meals — can disrupt your natural sleep rhythm. Thinking of your diet as part of a 24-hour wellness cycle can make a significant difference to sleep quality.

How nutrition affects sleep quality

The link between diet and sleep

Sleep is one of the most important foundations of health, just like diet, hydration, and exercise. Good sleep supports your mental wellbeing, memory, mood, and immune function. Yet many people don’t realise that what you eat and drink throughout the day can have a significant impact on how well you sleep at night.

Your diet influences the production of key sleep hormones like melatonin and serotonin, as well as minerals such as magnesium and calcium, which help the body relax. Some foods encourage deeper, more restorative sleep, while others like caffeine, alcohol, and heavy meals, can disrupt your natural sleep rhythm.

Why food affects sleep

1. Nutrients that promote better sleep

Melatonin – known as the sleep hormone, helps regulate your body clock and signals when it’s time to rest.
Tryptophan – an amino acid that your body uses to make serotonin and melatonin.
Magnesium – helps relax muscles and calm the nervous system.
Calcium – supports melatonin production and helps regulate muscle contractions.
Antioxidants – reduce inflammation and oxidative stress, both of which can interfere with restful sleep.

2. Timing matters

Eating too close to bedtime can lead to discomfort or indigestion, especially if meals are high in fat, sugar, or spice. Aim to eat 2–3 hours before bed to give your body time to digest, allowing sleep-enhancing nutrients to work effectively.

Building a sleep-friendly eating routine

To improve your sleep quality, think of your diet as part of your 24-hour wellness cycle. Here are a few extra tips:

1. Eat balanced meals during the day

Include protein, fibre, healthy fats, and complex carbohydrates to keep blood sugar stable and avoid evening cravings.

2. Stay hydrated — but time it right

Dehydration can make you feel sluggish, but drinking too much water late at night can interrupt sleep. Try to finish most of your fluids at least one hour before bed.

3. Cut caffeine after midday

Caffeine can stay in your system for up to eight hours. Switch to decaf tea, fruit infusions, or water after lunch.

4. Pair food with good sleep habits

Nutrition is only one piece of the puzzle. Combine healthy eating with a consistent bedtime, relaxing evening routine, and a calm sleep environment.

Example evening routine for better sleep

Time	Habit	Why It Helps
6:30–7:00 pm	Eat a light, balanced dinner	Gives your body time to digest
8:30 pm	Sip chamomile tea or warm milk	Signals to your body that it’s time to wind down
9:00 pm	Avoid screens and bright lights	Helps melatonin rise naturally
9:30 pm	Try gentle stretches or breathing exercises	Reduces tension and prepares your body for rest
10:00 pm	Lights out	Aim for 7–9 hours of uninterrupted sleep

The bottom line

What you eat can have a powerful impact on how well you sleep. A nutrient-rich diet that includes magnesium, tryptophan, and melatonin-rich foods can help you fall asleep faster, stay asleep longer, and wake feeling more refreshed.

Good nutrition and good sleep go hand in hand, both are vital for energy, mood, and long-term health. Start by making small, mindful changes to your meals and bedtime habits, and you’ll likely notice the difference in just a few nights.
