The Science of Sleep: Foods and Nutrients that help us Rest

Too tired, but not sleeping well enough? Well, sleep isn’t just about feeling tired—it’s a finely tuned biochemical process. Hormones, neurotransmitters, and key nutrients work together to regulate it, and the right foods fuel better sleep, deeper rest, and optimal recovery. Here’s a cheat sheet to help you master it.

1. Melatonin – The Sleep Hormone

Melatonin signals to your body that it’s time to sleep. Some foods naturally contain melatonin, while others help your body produce more of it.

• Tart cherries – One of the richest natural sources of melatonin, clinically proven to improve sleep duration.

• Walnuts – Contain melatonin and omega-3s, which aid its production.

• Oats – A surprising source of melatonin, making them an excellent bedtime snack.

2. Tryptophan – The Precursor to Serotonin & Melatonin

Tryptophan is an essential amino acid that converts into serotonin (stabilising mood) and melatonin (promoting sleep).

• Turkey – The classic source (hence the post-dinner-snooze holiday tradition).

• Milk – Tryptophan + calcium (which helps convert tryptophan into melatonin).

• Bananas – Provide both tryptophan and magnesium for relaxation.

• Oats – Offer tryptophan and slow-digesting carbs that help transport it to the brain.

3. Magnesium – The Muscle Relaxer

Magnesium calms the nervous system, regulates melatonin, and reduces cortisol (the stress hormone), all essential for deep sleep.

• Almonds – High in magnesium and also contain melatonin.

• Bananas – Magnesium + potassium to relax muscles.

• Pumpkin seeds – One of the richest sources of magnesium.

• Dark chocolate – Contains magnesium and serotonin-boosting properties.

4. Omega-3 Fatty Acids – The Brain’s Sleep Aid

Omega-3s support serotonin production and help regulate melatonin. Low levels of it are linked to sleep disturbances.

• Oil rich fish (salmon, mackerel, sardines) – Omega-3s + vitamin D, which supports serotonin.

• Walnuts – A plant-based omega-3 source.

• Flaxseeds & chia seeds – Great for those on a plant-based diet.

5. Vitamin D – The Circadian Rhythm Regulator

Vitamin D plays a role in sleep regulation by supporting serotonin production. Its deficiency is linked to insomnia.

• Oil rich fish – Again, one of the best natural sources.

• Egg yolks – contain vitamin D + tryptophan.

• Mushrooms – The only plant-based source of vitamin D when exposed to sunlight.
