Also asked, When is the best time to take vitamin D tablets?
For maximum absorption, the best time to take vitamin D and other fat-soluble vitamins is after you've eaten foods that contain fat. And you don't need much: Dr. Perez-Gallardo says even small amounts of low- or whole-fat milk or yogurt will do the trick. So will eating food cooked with oil.
Then, Is vitamin D energizing?. Vitamin D proven to boost energy – from within the cells
A hormone normally produced in the skin using energy from sunlight, Vitamin D can also be found in a few foods – including fish, fish liver oils, egg yolks and fortified cereals but it can also be effectively boosted with Vitamin D supplements.
Furthermore, Which vitamins keep you awake at night?
B Complex Vitamins
Especially since taking one before bed can keep you awake. There are eight B vitamins in all, which also go by the names of thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9) and cobalamin (B12).
Does vitamin D Help sleep?
Results: Vitamin D receptors and the enzymes that control their activation and degradation are expressed in several areas of the brain involved in sleep regulation. Vitamin D is also involved in the pathways of production of Melatonin, the hormone involved in the regulation of human circadian rhythms and sleep.
Current guidelines say adults shouldn't take more than the equivalent of 100 micrograms a day. But vitamin D is a 'fat-soluble' vitamin, so your body can store it for months and you don't need it every day. That means you could equally safely take a supplement of 20 micrograms a day or 500 micrograms once a month.
One study found that low vitamin D was high among people with fatigue and that their symptoms improved after five weeks of vitamin D supplements, while a small study from Newcastle University found that low vitamin D could cause fatigue as low levels cause mitochondria, the 'power stations' in every cell of the body, ...
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.
The Bottom Line
Taking vitamin D with food can enhance its effectiveness, as it's fat-soluble. While the best timing has not been established, scientific data to confirm anecdotal reports that supplementing at night may interfere with sleep is unavailable.
When to take supplements
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.”
Interestingly, several studies have also found that supplementing with vitamin D could reduce the severity of fatigue in people with a deficiency ( 14 , 15 ).
Research has shown that vitamin D might play an important role in regulating mood and warding off depression. In one study , scientists found that people with depression who received vitamin D supplements noticed an improvement in their symptoms.
A vitamin D deficiency is unlikely to cause weight gain. However, it may cause other health problems or unpleasant symptoms, which are worth avoiding. You can maintain adequate vitamin D levels through a combination of limited sun exposure, a vitamin-D-rich diet, and taking vitamin D supplements.
Signs and symptoms might include:
- Bone pain.
- Muscle weakness, muscle aches, or muscle cramps.
- Mood changes, like depression.
Some side effects of taking too much vitamin D include weakness, dry mouth, nausea, vomiting, and others. Taking vitamin D for long periods of time in doses higher than 4000 IU (100 mcg) daily is possibly unsafe and may cause very high levels of calcium in the blood.
Physiological actions of vitamin D
Calcitriol (1,25-dihydroxyvitamin D3), the active form of vitamin D, has a half-life of about 15 h, while calcidiol (25-hydroxyvitamin D3) has a half-life of about 15 days.  Vitamin D binds to receptors located throughout the body.
Nearly all vitamin D overdoses come from supplements. The Institute of Medicine's Food and Nutrition Board's old 1997 recommendations suggested that 2,000 IU per day of vitamin D is safe for adults and that 1,000 IU per day is safe for infants up to 12 months of age.
We suggest that all adults who are vitamin D deficient be treated with 50,000 IU of vitamin D3 once a week for eight weeks or its equivalent of 6,000 IU of vitamin D3 daily to achieve a blood level of 25(OH)D above 30 ng/mL, followed by maintenance therapy of 1,500-2,000 IU/day.
In summary, long-term supplementation with vitamin D3 in doses ranging from 5000 to 50,000 IUs/day appears to be safe.
Large doses of minerals can compete with each other to be absorbed. 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.
Dwyer says vitamin D, calcium, and folic acid are three nutrients you may get too much of, especially through supplements. Adults who regularly far exceed the 4,000 international units (IUs) daily safe upper limit for vitamin D might may end up with serious heart problems.
Long-term zinc supplementation at these levels should be accompanied by supplements of copper and perhaps calcium, iron, and magnesium. Large amounts of zinc (over 50 mg per day) should only be taken under the supervision of a doctor.
Vitamin D3 therapy (50,000-100,000 IU/week) was safe and effective when given for 12 months to reverse statin intolerance in patients with vitamin D deficiency. Serum vitamin D rarely exceeded 100 ng/mL, never reached toxic levels, and there were no significant change in serum calcium or eGFR.
One 2011 protocol from the Endocrine Society suggests a very high dose of vitamin D3: 50,000 IU, once a week for two to three months or three times a week for one month to restore the nutrient in the body to above 30 ng/mL for those who are deficient.
Daily vitamin D was more effective than weekly, and monthly administration was the least effective.
