Compared with the placebo group, individuals treated for three months with daily zinc supplements demonstrated an improved sleep onset latency and sleep efficiency compared to control subjects (Figure 1A). Dietary zinc improves sleep quality in humans and increases NREM sleep in mice.
Zinc doesn't seem to trigger sleep, but adequate levels of zinc in the blood shorten the time it takes to fall asleep (sleep latency), increase the overall amount of sleep, and assure sleep quality and efficiency (time spent asleep when in bed).
Consumption of Zinc helps to have less wake-ups in the night. It is an excellent & safe sleep aid; and also has a calming & antidepressant effect. Along with helping to regulate sleep, Zinc has shown to improve the vividness of dreams.
Zinc is often part of multivitamins but is also taken alone or in combination with vitamin C. Its absorption is most effective on an empty stomach, but it can cause stomach upsets. In this case it should be taken with a meal and therefore not late at night.
Then, there was the randomised controlled trial involving older Italian adults who struggled to sleep; it was discovered that over an eight-week period, those who took a combination of melatonin, magnesium, and zinc one hour before bed reported “considerably better” sleep scores than those who took a placebo.
Both magnesium and zinc may improve your sleep quality. Studies show that magnesium helps stimulate your body's parasympathetic nervous system, which helps you feel calm and relaxed ( 19 ). Plus, human and animal studies associate zinc supplements and higher blood zinc levels with improved sleep quality ( 20 , 21 ).
Inhaling zinc fumes can cause flu-like symptoms, such as fever, chills, cough, headache, and fatigue ( 4 ). These symptoms occur in many conditions, including other mineral toxicities. As a result, diagnosing zinc toxicity can be difficult (5).
Do not take zinc supplements and copper, iron, or phosphorus supplements at the same time. It is best to space doses of these products 2 hours apart, to get the full benefit from each dietary supplement.
Magnesium assists your body in regulating zinc levels, but high intakes of zinc can be detrimental to magnesium absorption – only abnormally high doses (around 142 mg of zinc per day) will reduce magnesium absorption.
Zinc helps to regulate the menstrual cycle by nourishing healthy ovarian follicles and therefore promoting ovulation. Premenstrual mood symptoms. According to a 2022 randomized clinical trial, zinc supplementation can improve PMS.
Zinc is involved in processes in the brain that control sleep. Some preliminary research suggests that supplementing with zinc-containing formulas may help improve sleep, but, as explained in the What It Does — For sleep section of the Zinc Supplements Review, taking zinc alone has not been proven to help with sleep.
The short answer is yes, but not at the same time. Taking high levels of zinc (142 milligrams a day and up) in supplement form may interfere with magnesium absorption. If you are taking zinc at extremely high doses due to medical issues, take the zinc several hours before or after taking a magnesium supplement.
Zinc is an essential nutrient that supports many of our body's functions, including immune function, cellular health, and certain brain functions. It can also affect our mood, with zinc deficiencies often linked to anxiety and depression. By maintaining proper zinc levels, we can help improve our overall well-being.
Zinc supplementation significantly reduced fatigue (mean difference: −10.41 vs 1.37, P < . 001) and increased serum zinc level (mean difference: 14.22, vs −0.57, P < . 001) compared to the control group.
Growing evidence has demonstrated that vitamin D has a role in sleep regulation [12]. Specifically, vitamin D deficiency (VDD) can increase risk of sleep disorders and is associated with sleep difficulties, shorter sleep duration, and nocturnal awakenings in children and adults [13,14,15].
Zinc deficiency can happen in people who have problems absorbing nutrients, for example, older people and those who have some gut diseases. Some medicines can also increase the loss of zinc through urine.
In general, magnesium seems to have minimal side effects, and taking low doses is unlikely to cause much harm. According to the Institute of Medicine, healthy adults can safely take up to 350 milligrams of supplemental magnesium daily. Anything at or below that level is unlikely to cause any adverse health effects.
When taken together in the right quantity, Zinc and Magnesium work to each other's advantage. Magnesium plays a vital role in the body to regulate Zinc levels. However, the excess consumption of Zinc can be detrimental to Magnesium absorption and may lead to Magnesium imbalance in the body.
It is possibly safe when taken in larger doses, especially when used only for a short period of time. But taking doses higher than 40 mg daily might decrease how much copper the body absorbs. Taking very high doses of zinc is likely unsafe and might cause stomach pain, vomiting, and many other problems.
Your body doesn't need a large amount of zinc. The recommended daily allowance for adults is 8 - 11 mg. It's common to have slightly low levels of zinc, but taking a multivitamin, plus eating a healthy diet, should give you all the zinc you need.
Interactions between your drugs
No interactions were found between Vitamin D3 and Zinc.
This usually occurs when a person takes an excess of zinc supplements to boost their immune system. Too much zinc intake can cause symptoms that range from nausea and vomiting to impaired immune system functioning. For this reason, adults older than age 19 should not take more than 40 milligrams (mg) of zinc a day.
One of the biggest benefits of taking either a zinc supplement or adding more zinc filled foods into your diet is that it has been shown to protect your eyes against macular degeneration and some forms of night blindness.
Adverse effects of high zinc intake include nausea, vomiting, loss of appetite, abdominal cramps, diarrhea, and headaches. Intakes of 150–450 mg of zinc per day have been associated with such chronic effects as low copper status, altered iron function and reduced immune function.
