The Unexpected Sleep Benefits of Zinc
Zinc plays a crucial role in sleep quality, which is often overlooked. A zinc deficiency can lead to poor sleep, among other health issues.
Zinc’s Functions in Sleep Regulation
- Zinc is the second most abundant trace mineral in the brain
- It’s involved in neurotransmitter function
- Zinc helps build up adenosine, which creates sleep pressure
- It’s involved in the production of dopamine, serotonin, and melatonin
- Zinc influences glutamate pathways affecting deep sleep
- It acts as a sleep modulator, helping control sleep
How to Take Zinc for Sleep
- Take zinc with copper in a 10:1 ratio
- For every 8-10mg of zinc, take 0.5-1mg of copper
- Consider taking zinc and copper with a blend of trace minerals
Foods Rich in Zinc
- Oysters have the highest zinc content
- Oysters also contain taurine and GABA receptor agonists, beneficial for sleep
- People with shorter sleep duration typically have less zinc in their bodies
Importance of Adequate Zinc Intake
The blood-brain barrier has low permeability for zinc, emphasizing the need for sufficient zinc intake to ensure proper sleep regulation.
So let’s dive into the details…
Zinc and sleep
The Surprising Connection Between Zinc and Sleep Quality
Now zinc does so many things – it’s involved in over 300 different pathways but recently I found out that zinc has an unexpected sleep benefit. Typically when you think of a zinc deficiency you think of a child not growing very fast or someone having low testosterone or they can’t taste or smell or they have poor wound healing or a poor immune system or even they may develop an ulcer but one huge symptom for a lack of zinc is poor sleep.
Key Points:
- Zinc is involved in over 300 different bodily pathways
- Zinc deficiency can lead to various health issues
- Poor sleep is a significant symptom of zinc deficiency
Zinc deficiency
Common Symptoms of Zinc Deficiency
So zinc has a major influence over the central nervous system. In fact, it’s the second most abundant trace mineral in your brain. It’s involved in neurotransmitters which are those hormone communications that travel through the nervous system. It’s also essential for making adenosine.
Zinc’s Role in the Body:
- A major influence on the central nervous system
- Second most abundant trace mineral in the brain
- Involved in neurotransmitter function
- Essential for adenosine production

The Crucial Role of Zinc in Sleep Regulation
Now what is adenosine? Adenosine is a molecule that gradually builds up through the day and creates sleep pressure.
It’s that compound that controls pressure that pushes you into a deep sleep and all night long when you’re sleeping adenosine breaks down and then you become awake.
Right also caffeine blocks adenosine and that’s why caffeine makes you more awake but zinc will help you build up more adenosine which is sleep pressure.
Zinc is also involved in making dopamine. It’s also involved in making serotonin which then turns into melatonin the sleep hormone.
Also zinc is involved in certain biochemical pathways involving glutamate which has a profound effect on deep sleep. So zinc is what is called a sleep modulator it helps control sleep.
Zinc’s Functions in Sleep Regulation:
- Helps build up adenosine (sleep pressure)
- Involved in dopamine production
- Assists in serotonin and melatonin production
- Influences glutamate pathways affecting deep sleep
- Acts as a sleep modulator
How to take zinc for sleep
Proper Zinc Supplementation for Better Sleep
Now anytime you take zinc I also recommend you take it with copper in a certain ratio. So for every eight to ten milligrams of zinc you want to take point five to one milligrams of copper.
And 0.5 milligrams of copper is 500 micrograms so roughly you’d want 10 times more zinc than you do copper. And I also recommend taking that zinc copper and a blend of trace minerals.
Zinc Supplementation Guidelines:
- Take zinc with copper in a 10:1 ratio
- For every 8-10mg of zinc, take 0.5-1mg of copper
- Consider taking zinc and copper with a blend of trace minerals
Foods rich in zinc
Natural Sources of Zinc for Better Sleep
Now out of all the food that you can eat oysters have the highest amount of zinc and also oysters are loaded with taurine which is not only good for increasing your physical performance but it’s also good for your sleep cycles and oysters also have something called GABA receptor agonist.
Now what is that? That is something that activates GABA okay and GABA is all about calming the nervous system down helping you sleep.
And it’s been found that people with shorter amount of sleep have significantly less zinc than those people who can sleep longer and lastly the blood-brain barrier has low permeability for zinc
so if you’re very deficient in zinc you’re just not going to sleep so it really helps to beef up no pun intended your zinc supply all right so there’s many things you can do for sleep and zinc is definitely one thing to add to the list.
Zinc-Rich Foods and Their Benefits:
- Oysters: Highest zinc content, also rich in taurine and GABA receptor agonists
- Zinc deficiency linked to shorter sleep duration
- Low zinc permeability in the blood-brain barrier emphasizes the importance of adequate zinc intake
Summary
Zinc is involved in so many things. It’s involved in over 300 pathways in the body. But, recently, I found out that zinc has an unexpected sleep benefit.
Typically a zinc deficiency is related to problems, such as:
• A child not growing quickly
• Low testosterone
• Loss of taste and smell
• Poor wound healing
• Poor immunity
• Ulcers
But a huge symptom of a zinc deficiency is poor sleep.
Different functions of zinc:
• It has a significant influence over the central nervous system
• It’s involved in neurotransmitters
• It’s essential for making adenosine
• It’s involved in making dopamine
• It’s involved in making serotonin
• It exists in glutamatergic neurons (affects deep sleep)
- Zinc is a sleep modulator. It helps control sleep. Any time you take zinc, you also want to take copper. For every 8-10mg of zinc, take .5-1mg of copper. You may also find it beneficial to get your zinc and copper from a blend of trace minerals.
- Oysters have the highest amount of zinc. They are loaded with taurine, which supports physical performance and sleep. They also contain GABA receptor agonist, which supports sleep.
