Zinc for Sleep : Does it help?

Many essential minerals, such as magnesium, iron, and zinc, have shown to be necessary for the crucial activity of getting a good night’s sleep. Minerals act in our body by aiding in immunity, metabolism, and functioning as antioxidants. To delve deeper into this subject, let’s explore the use of zinc for sleep.

What is Zinc?

Zinc is a vital mineral that plays many roles in the body, primarily in cellular metabolism, from supporting the immune system to aiding in wound healing.

Zinc also has anti-inflammatory and antioxidant properties, contributing to overall well-being.

But can zinc also affect your sleep patterns?

Does Zinc Help Sleep?

You might wonder if there’s any scientific basis to the claim that zinc can positively influence your sleep.

Research suggests that zinc might indeed play a role in sleep regulation. Some studies indicate that a deficiency in zinc could be linked to sleep disturbances.

However, it’s important to note that the relationship between zinc and sleep is complex and yet, poorly understood.

In a study from 2017, the potential link between zinc and sleep regulation was explored. Their research suggested that zinc serum concentration fluctuates with sleep duration and that orally administered zinc supplements can enhance sleep quality and quantity in both mice and humans.

Results of another research indicated that ICU nurses who received zinc supplementation had significantly improved sleep quality scores and higher serum zinc levels compared to the control group.

Another study found that zinc supplementation led to increased quality of life scores, particularly in physical aspects. Although sleep quality showed marginal improvement in the zinc group, the study highlights the potential benefits of zinc supplementation on both quality of life and sleep among young women with PMS.

Additionally, other researches revealed that the supplemented group experienced significant improvements in sleep quality scores and various sleep-related domains. The combination of melatonin, magnesium, and zinc appeared to positively impact sleep quality and overall well-being in the context of primary insomnia.

How Much Zinc Should I Take to Sleep?

Before rushing to buy zinc supplements, it’s crucial to determine the appropriate zinc dosage.

The recommended dietary allowance (RDA) for zinc varies based on factors like age, gender, and life stage. As a general guideline, zinc supplement doses vary from 5–10 mg to 25–45 mg.

It’s important not to exceed these limits, as excessive zinc intake can lead to adverse health effects.

Can You Take Zinc at Night Before Bed?

If you’re considering incorporating zinc into your nighttime routine, you might be wondering about the best time to take it.

While no specific proven time is superior, some experts suggest taking zinc with a meal to enhance its absorption.

Regardless of whether you choose to take it in the morning or at night, consistency is key to reaping potential benefits.

Can Lack of Zinc Cause Insomnia?

Research suggests that a deficiency in zinc might contribute to sleep disturbances, but it’s unlikely to be the sole cause of insomnia.

Sleep is a complex process influenced by various factors, including lifestyle, stress levels, and overall health. Addressing a zinc deficiency might be one step toward improving your sleep quality, but a holistic approach is crucial.

What is the Best Form of Zinc for Sleep ?

There are numerous ways to incorporate zinc into your routine. Eating foods like beans, fish, meat, nuts, and seeds with zinc can help you get enough of this mineral.

Additionally, zinc supplements and zinc tablets are available in various forms, including pills, capsules, and lotions.

Magnesium and iron are also important minerals for sleep; including foods rich in these minerals in your diet can be beneficial.

Other Minerals and Their Role in Sleep

Many other minerals can assist in sleep, such as iron and magnesium.

Like zinc, magnesium is essential for various bodily functions. It’s involved in muscle, nerve function, and energy production.

Moreover, magnesium and sleep are also linked, known to have a calming effect on the body, potentially promoting better sleep.

Iron, another essential mineral with potential benefits for sleep, is involved in the production of melatonin, the hormone responsible for regulating sleep-wake cycles.

A study has demonstrated that iron influences melatonin production by affecting the expression of the hepcidin gene. This hormone is crucial for maintaining iron balance and homeostasis.

Notably, an insufficiency of iron can contribute to sleep disorders such as restless leg syndrome.


In conclusion, while the impact of zinc on sleep isn’t fully understood, it’s clear that this mineral plays a crucial role in overall health.

Incorporating zinc-rich foods into your diet or discussing zinc supplementation with a healthcare professional could be steps toward supporting your well-being.

Remember that achieving a good night’s sleep involves a combination of factors, including a healthy lifestyle, stress management, and a balanced diet.

As you embark on your journey toward better sleep, consider exploring the potential benefits of zinc and magnesium while maintaining a well-rounded approach to your overall health.

Your quest for a restful night’s sleep is noble; with the right information and strategies, you’re on the path to achieving your sleep goals.
