Top 4 Supplements to Improve Sleep

June 07, 20256 min read

In today’s fast-paced world, getting truly restorative sleep has become more of a luxury than a norm. Many of us lie awake at night, our minds racing, wishing we could just fall asleep easily. If you’ve been there, you know how frustrating it can be. That’s why I created this guide to the top 4 supplements to improve sleep. While deep healing often comes from addressing root causes, temporary relief can make a big difference in your overall wellbeing.

Let’s explore why sleep matters, how nutrition plays a surprising role, and what supplements can help support restful, rejuvenating sleep.


Why Sleep Is So Important

Sleep is when your body repairs, detoxifies, and restores. In particular, sleep activates the brain’s glymphatic system, which flushes out toxins and metabolic waste through cerebrospinal fluid movement. This process supports brain function, memory consolidation, and mood regulation.

Poor sleep is linked to:

  • Increased risk of depression and anxiety

  • Brain fog and forgetfulness

  • Hormonal imbalances

  • Increased inflammation and chronic illness

To truly optimize health, we have to prioritize sleep as a non-negotiable part of daily life.


Nutrition-Related Sleep Disruptors

Many people assume sleep issues are strictly stress-related, but nutrition plays a major role too. These are three of the most common nutritional imbalances I see affecting sleep:

1. Blood Sugar Imbalances

When blood sugar drops too low during the night, your body releases cortisol (a stress hormone) to stabilize it. This cortisol spike can wake you up or prevent you from falling asleep.

Eating fast-digesting carbs or sugary snacks before bed may seem comforting, but they often lead to blood sugar crashes that disrupt your sleep cycle. Instead, aim for a balanced evening meal with:

  • Healthy fats

  • Quality protein

  • Slow-digesting carbohydrates (like sweet potato or quinoa)

2. Nutrient Deficiencies

Neurotransmitters like GABA and melatonin help your brain and body relax and prepare for sleep. But these calming chemicals require nutrients such as:

  • Magnesium

  • Zinc

  • B6

  • Tryptophan

  • Taurine

If you’re deficient in these, it’s harder for your body to wind down. A healthy diet rich in leafy greens, nuts, seeds, high-quality animal proteins, and legumes is a must. Also, make sure your gut is healthy enough to absorb these nutrients.

3. Poor Gut Health

Surprise! Your gut produces more melatonin than your pineal gland. If your microbiome is off-balance, you may not make or absorb enough of the neurotransmitters needed for restful sleep.

Tips for supporting gut health:

  • Eat fermented foods (like sauerkraut and kefir)

  • Drink bone broth

  • Take a high-quality probiotic

  • Avoid food sensitivities (commonly: gluten, dairy, caffeine, and nightshades)


What is a Healing Diet for Sleep?

To support your body’s natural sleep processes, follow a healing diet that:

  • Balances blood sugar

  • Provides essential sleep-supporting nutrients

  • Reduces inflammation

  • Supports gut repair

Key principles:

  • Eat whole, unprocessed foods

  • Avoid artificial ingredients and inflammatory oils

  • Focus on nutrient density

  • Rotate food choices to reduce exposure to potential allergens

Now, let’s talk about supplements that can help you get to sleep, stay asleep, and wake up refreshed.


Top 4 Supplements to Improve Sleep

1. Magnesium

Magnesium is one of the most essential minerals for relaxation, sleep, and nervous system health. It supports:

  • GABA production (your brain’s calming neurotransmitter)

  • Melatonin synthesis

  • Blood sugar regulation

  • Muscle relaxation

Best forms:

  • Magnesium glycinate

  • Magnesium threonate (crosses the blood-brain barrier)

2. Adaptogens

Adaptogens are herbs that help your body adapt to stress. They can:

  • Lower cortisol

  • Balance the stress response

  • Calm the nervous system

Best for sleep:

  • Ashwagandha

  • Magnolia bark

  • Reishi mushroom

  • Rhodiola

3. Calming Herbs

Certain herbs have natural sedative and calming properties that help ease you into sleep:

  • Chamomile

  • Valerian root

  • Passionflower

  • Lemon balm

  • Kava

  • Lavender

These are excellent for occasional use or nightly as part of a sleep routine.

4. Melatonin

Melatonin is your body’s sleep hormone. While it’s always best to optimize your natural melatonin production first (through light exposure and circadian rhythms), supplemental melatonin can be helpful for:

  • Jet lag

  • Sleep cycle resetting

  • Occasional sleep difficulties

Important: Don’t use melatonin every night unless guided by a professional. Overuse can suppress your body’s own production over time.

Hack: Reset Your Sleep with Nature

One of the most overlooked sleep remedies is reconnecting with nature.

Try a weekend of camping without electronics or artificial light. Research shows that just two days in nature can reset your circadian rhythm, helping you fall asleep earlier and sleep more deeply.

Being in nature also:

  • Lowers cortisol

  • Boosts melatonin

  • Enhances mood and creativity

If you can’t go camping, even daily sunlight exposure and evening walks can help reset your sleep-wake cycle.
