Jeffrey Blumberg, a professor of nutrition science and policy at Tufts University in Boston, says otherwise. He suggests taking your dietary supplements at night isn't advisable. “Digestion slows down during sleep, so taking your nutrient supplement late at night would not be associated with an efficient absorption.”
Vitamins and supplements that may be better when taken in the evening, close to bedtime, include: Magnesium. Vitamin B-3 (niacin)
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.
Omega-3, Vitamin D
A study in the Journal of Clinical Sleep Medicine found the combination of omega-3s and vitamin D from fatty fish like salmon improved sleep in participants. Researchers think it's because of the effect of those nutrients on regulating serotonin.
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.
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.
Don't use calcium, zinc, or magnesium supplements at the same time. Also, these three minerals are easier on your tummy when you take them with food, so if your doctor recommends them, have them at different meals or snacks.
You can—but it's probably not a good idea. For some supplements, optimal absorption can depend on the time of day taken. Not only that—taking certain vitamins, minerals, or other supplements together can also reduce absorption and may result in adverse interactions, which can be harmful to your health.
B vitamins work together (such as in a B complex supplement that contains B12, folate, B6, etc.), so they can/should be taken together. Vitamin C and iron (C helps the body absorb more iron, from both foods and supplements) Vitamin K and calcium (both support skeletal and heart health)
While magnesium is a mineral that assists numerous processes in your body, melatonin is a hormone which contributes to regulating your sleep and circadian rhythm. Generally speaking, magnesium helps your body relax and melatonin supports falling asleep faster.
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!
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.
Vitamin D. Several studies link vitamin D to sleep quality. Various research³ associates a lack of adequate vitamin D in your blood with a higher risk of poorer sleep quality. On the other hand, high doses of vitamin D consumption may be related to reducing melatonin⁴ levels, the hormone that controls your sleep cycle.
Use melatonin supplements .
“Melatonin is a hormone that is naturally released in the brain four hours before we feel a sense of sleepiness,” Gamaldo says. It's triggered by the body's response to reduced light exposure, which should naturally happen at night.
Several of the most popular natural sleep aids include melatonin, GABA, tryptophan, 5-HTP, CBD and THC, valerian root and lavender.
Symptoms of magnesium deficiency
Weakness and fatigue. Tremors or muscle twitching. Muscle cramping. Heart palpitations or heart arrhythmias.
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 ...
