It is a good idea to take magnesium before bed because it can help you sleep. Because calcium and magnesium compete for absorption, they should not be consumed at the same time. Another reason that it is not good to take calcium at night is because vitamin D should be combined with complete meals.
Yes! You can and should take magnesium and vitamin D together. In fact, the bioavailability of vitamin D largely relies on magnesium. Also, many nutrients wouldn't work efficiently without magnesium, further highlighting the importance of this mineral!
Our only hard recommendation: Avoid supplementing with vitamin D at night. There's evidence that vitamin D can suppress melatonin—which is bad news for your sleep quality.
Is there a benefit to taking vitamin D at night? There's been some buzz suggesting a link between supplementing with vitamin D before bedtime and the ability to drift off to dreamland. Some studies have shown that vitamin D is connected to the production of melatonin, which regulates circadian rhythm and drives sleep.
Dean. "Adequate levels of magnesium in the body are essential for the absorption and metabolism not only of vitamin D but of calcium as well," Dean states. "Magnesium converts vitamin D into its active form so that it can help calcium absorption.
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
Magnesium and calcium/multivitamin
But if you do take magnesium, Erin Stokes, ND, recommends not taking it at the same time as your multivitamin, as it may interfere with the absorption of smaller minerals found in the multivitamin, like iron and zinc.
Magnesium can decrease the absorption and effectiveness of numerous medications, including some common antibiotics such as tetracycline (Achromycin, Sumycin), demeclocycline (Declomycin), doxycycline (Vibramycin), minocycline (Minocin), ciprofloxacin (Cipro), levofloxacin (Levaquin), moxifloxacin (Avelox) and ofloxacin ...
And if you're routinely consuming refined grains in lieu of whole grains, you may be short on dietary magnesium, which ultimately affects your vitamin D levels. If you choose to supplement with magnesium, "taking less than 300 mg of magnesium for men and 270 mg for women is generally recommended," Sasse says.
Therefore, magnesium supplements can be taken at any time of the day, as long as you're able to take them consistently. For some, taking supplements first thing in the morning may be easiest, while others may find that taking them with dinner or just before bed works well for them.
While the best timing has not been established, scientific data to confirm anecdotal reports that supplementing at night may interfere with sleep is unavailable. Current research suggests you can fit vitamin D into your routine whenever you prefer.
Taking vitamin d in the morning
Whether you go for a supplement that's only vitamin D or a multivitamin that contains an appropriate amount of vitamin D, taking it in the morning is a great way to ensure you're getting enough.
It seems vitamin D helps you sleep because it takes part in the regulation of our circadian rhythms. Increasing dosages could be the first step to improving sleep, but pay attention to its effects. Vitamin D may suppress melatonin production. So take it in the day, not before bed.
An intervention study reported that vitamin D supplementation (D3) in veterans (50,000 IU/week) increased their sleep duration [56]. Another double-blind clinical trial showed use of vitamin D supplementation (50,000 IU/fortnight for 8 weeks) facilitated sleep duration and quality in people with sleep disorder [61].
You'll be sleepy the next day. Several studies even saw a dose-dependent relationship between vitamin D levels and sleep. [1,2] This adds to the evidence that there is a direct, linear relationship between vitamin D and sleep measures. This also means that improving your vitamin D by any amount will improve your sleep.
magnesium citrate cholecalciferol
Using cholecalciferol together with magnesium citrate can lead to elevated magnesium blood levels, particularly in individuals with reduced kidney function.
Anticonvulsants. The anticonvulsants phenobarbital and phenytoin (Dilantin, Phenytek) increase the breakdown of vitamin D and reduce calcium absorption. Atorvastatin (Lipitor). Taking vitamin D might affect the way your body processes this cholesterol drug.
Magnesium and zinc
All minerals and vitamins need the proper conditions for your body to absorb them properly. When taken together, magnesium and zinc have mutual benefits. Magnesium helps your body regulate its zinc levels, while zinc does the job of allowing it to absorb magnesium more effectively.
Some factors that may reduce or block its absorption include: Conditions such as celiac disease, chronic pancreatitis, Crohn's disease, and cystic fibrosis. These can all affect the intestines, preventing them from absorbing vitamin D found in food.
Magnesium supplements should be taken with meals. Taking magnesium supplements on an empty stomach may cause diarrhea.
One study of older adults with insomnia found that magnesium supplementation at a dose of 500 milligrams daily for eight weeks helped them fall asleep faster, stay asleep longer, reduced nighttime awakenings, and increased their levels of naturally circulating melatonin.
People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their health care provider. Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
The use of chemicals, such as fluoride and chlorine, bind to magnesium, making the water supply low in the mineral, as well. Common substances — such as sugar and caffeine — deplete the body's magnesium levels.
