When Is The Best Time To Take Vitamin D Supplements
Can the sunshine vitamin interfere with your sleep?.
Some vitamins are more effective when taken at particular times of the day.
The time at which we take our supplements affects the bodys ability to absorb vitamins, as well as whether any side effects occur.
Some vitamins should be taken in the morning, some in the afternoon, with a meal, on an empty stomach.
So when should you take vitamin D?
What Are The Benefits Of Taking A Vitamin D Supplement
The government says around 25% of teenagers and adults in the UK have low levels of vitamin D, which puts them at risk.
As there are so few food sources of vitamin D, and sun exposure can be unreliable, supplements are considered a safe way to prevent a deficiency.10
A 2013 review of evidence concluded that a vitamin D supplement could help protect against coughs and colds, while a separate 2013 study reported that women with lower levels of vitamin D experience tiredness and low energy.11,12
With so many factors putting us at risk of low levels, it makes sense to look at ways to supplement.
Some foods are fortified with Vitamin D, although you need to be sure it is Vitamin D3 and not just Vitamin D2.
Cod liver oil is a good source of Vitamin D supplementation .
A quality Vitamin D3 or wide-spectrum Vitamin D supplement is a sensible way to keep your daily levels topped up.
The most helpful aspect of taking any trustworthy health supplement is peace of mind. Just one little tablet or capsule per day and you can carry on knowing that you have covered your health bases.
With Vitamin D, you will be protecting your bone health, supporting your immune system, and helping your body build and maintain cells. That is why Vitamin D is one of the most important supplements you can take.
Taking Vitamin D Safely
Please make sure you read and comply with the instructions set out on the product label.
Each 1-A-Day vitamin D supplement contains 10 micrograms of vitamin D. This is equivalent to 400 international units of vitamin D. This is the daily amount recommended for the general population by government for general health and in particular to protect bone and muscle health.
If your GP has recommended that you take a different amount of vitamin D, you should follow your GPs advice.
Do not exceed the recommended dose equivalent to 400 international units). This is a safe level of intake, designed to meet your nutritional needs. Taking more is not currently recommended.
For most people taking up to 100 micrograms equivalent to 4,000 international units) per day is considered safe. In a few people, taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body . This can weaken the bones and damage the kidneys and the heart. NHS.UK has more information about vitamin D, including advice on intakes.
While some medications may interact with high doses of vitamin D, there are no issues associated with the 10 microgram vitamin D supplement. They are intended to supplement the diet and should not be substituted for a varied diet.

Taking Vitamin D And Magnesium Together
Magnesium plays a key role in determining how much vitamin D our bodies can make. Its suggested that people whose magnesium intake is high are less likely to have a vitamin D insufficiency than people whose magnesium levels are low.
Its also claimed that magnesium supplementation increases vitamin D levels in people who are deficient in the vitamin, but causes a reduction in people whose intake is high. Too much vitamin D can increase calcium levels, which in turn can lead to certain health complications.
Your Value Is Between 0
This value indicates severe vitamin D deficiency and represents significant risk to health. This low vitamin D level means that calcium cannot be sufficiently absorbed into the blood, which may lead to osteomalacia. This may also affect muscle strength and motor coordination.
If your vitamin D blood level is e.g. 25 ng/ml or higher and you want to increase them, you can take the following amount of vitamin D :
To reach the mentioned value.. take this vitamin D Dose per day:
20 ng/ml ..1000 IU 30 ng/ml ..2200 IU 40 ng/ml ..3600 IU 50 ng/ml ..5300 IU 60 ng/ml ..7400 IU 70 ng/ml ..10100 IU

What Type Of Vitamin D Is Best For Children
The government recommends a supplement of at least 10µg of vitamin D for children over the age of 1 and 8.5-10µg for babies under 1 year old.15
But getting children to take a supplement in tablet or capsule form is easier said than done we get it! Thankfully, there are some child-friendly supplements out there.
Getting Vitamin D From Sunlight
To make vitamin D, you need sunlight on your skin. From April until the end of September its possible to get enough vitamin D by spending time outside.
For most people, you only need to be outside for short periods of time, for example around 20-30 minutes. Although the exact time isnt known because its different for different people. If you have dark skin, for example if youre of south Asian, African or African Caribbean origin, you will need longer in the sun.
You need to have some skin exposed, for example, your forearms, hands and lower legs. But you can still make vitamin D even if you sit in the shade.
Sitting inside by a sunny window doesnt count because glass filters out the UVB rays the type of light that is needed to make vitamin D.
In the UK, we dont get enough vitamin D from sunlight between October and March, because the light doesnt contain enough UVB rays. During this time, we need to rely on getting enough vitamin D from food, and possibly supplements.
The guidelines in the UK are that everyone should consider taking a vitamin D supplement in the winter, especially if youre more like to have a deficiency.

Our nutritionists have created a handy guide outlining which type and form of vitamin D will help you thrive.
Whether you are looking for vitamin D for adults, vegans, children and babies or for when you are pregnant, there is a suitable type for everyone.
How Do I Get The Vitamin D I Need
Dont run out to the drug store to buy vitamin D pills just yet. Your body produces vitamin D when the skin is exposed to sun, and it is estimated that most people need 1,000 to 1,500 hours of sun exposure throughout the spring, summer, and fall to obtain the necessary amount of vitamin D. Vitamin D deficiency is very common and on the rise. This is mostly due to vigilant sun protection, since sunscreen with SPF 30 reduces vitamin D production by 95%. Of course, as a dermatologist I am not advocating for prolonged sun exposure, but small amounts can go a long way, as the skin produces vitamin D that can last at least twice as long the vitamin D you take in through foods or supplements. Vitamin D can also be obtained through other sources, including fatty fish , foods fortified with vitamin D , beef liver, cheese, and egg yolks. Of course, vitamin D supplements are needed for people most at risk for deficiency, including breastfed infants, older adults, people with limited sun exposure, darker skinned individuals, and overweight individuals.
Vitamin D And Osteoporosis
In the past, scientists have become very excited about other ‘antioxidant’ vitamins, particularly vitamins A, C and E and their role in preventing heart disease. The thinking went something like this: people who eat lots of fruit and veg are less likely to have heart attacks fruit and veg are high in antioxidant vitamins antioxidants are a good thing because they mop up ‘free radicals’ which can damage DNA so if people don’t get their vitamins through fruit and veg, giving them in supplement form will be just as good. In fact, when the studies were done, topping up with supplements didn’t cut heart disease risk at all.
The new study shows a similar result for vitamin D, at least as far as fractures, falls and bone density are concerned. There is no evidence that taking supplements cuts the risk of fractures or falls, or improves bone density. So doctors need to question whether they should be prescribing to people at risk of osteoporosis, and we all have to go back to the drawing board to protect ourselves.
For strong bones, calcium is also important. Dairy products, seeds, pulses, tofu, tinned fish with bones and some green leafy vegetables are all good sources. Interestingly, calcium supplements don’t appear to help much, and recent research suggests they may actually increase the risk of heart attack, so doctors are much more wary about prescribing these too.

How much vitamin D should women take per day?
According to the USDA and National Institutes of Health, the standard recommendation of vitamin D that adult women should take in order to prevent deficiency is between 600 to 800 international units per day, depending on age. The exact number is debatable, and some experts feel that a higher dose of vitamin D, around 2,ooo to 5,000 IU per day, may be more beneficial.
How much vitamin D should men take per day?
The standard recommendation for adult men is also between 600 to 800 IU of vitamin D per day. Adults over 70 should supplement with more, at least 800 IU per day, while younger adults need at least 600 IU daily.

The Vitamin D Deficiency Crisis
Vitamin D deficiency is rife across the globe, particularly in the United States.
When we consider vitamin D s vast array of health benefits, and its ability to ward off nasty diseases, it’s shocking to learn that approximately 40% of the American population suffers from a vitamin D deficiency.
This staggeringly high statistic largely comes down to a lack of sun exposure and ow consumption of vitamin D-rich foods.
It, therefore, comes as no surprise then that dietitians often recommend vitamin D supplementation.
However, there is a such a thing as too much vitamin D – known as Vitamin D Toxicity.
If you’re concerned that you’re getting too much or too little vitamin D, it’s worth checking in with your doctor and measuring your vitamin D levels.
Toxicity is caused by having too much vitamin D in the system, which can lead to a condition called hypercalcemia .
Regardless, if you’re concerned that you’re getting too much or too little vitamin D, it’s worth checking in with your doctor and measuring your vitamin D levels.
To learn more about the telltale signs of a vitamin D deficiency, and testing vitamin D levels, read our blog post on how to know if you’re deficient in Vitamin D.
Vitamin D toxicity is a much rarer case than being vitamin d deficient though, so have no fear.
What You Can Do Now
If youre concerned about vitamin D deficiency, ask your doctor to check your vitamin D level, says Dr. Deal. If the level is low and your provider starts you on supplements, you need repeat testing in eight to 12 weeks to make sure the level is not too high or too low.
If testing shows your vitamin D level is normal, you need repeat testing every two to three years unless you have major changes in your overall health.
Different diseases need different doses of vitamin D. If you have chronic kidney disease or parathyroid disease, ask your kidney specialist or endocrinologist about the type and dose of vitamin D you need.
If youre pregnant or breastfeeding, Dr. Deal recommends you keep taking vitamin D supplements as long as your doctor prescribes them. The supplement is linked to healthy development for you and your baby.
For bone health, be sure to stay active and remember to eat a calcium-rich diet. Consult with your doctor frequently to make sure youre taking the right steps to current bone health.
How Much Vitamin D Is Too Much
Because vitamin D is fat soluble, there have been repeated warnings against overdosing. In 2002, the Scientific Committee on Food of the European Commission released its position the safety of vitamin D.
The report stated that a daily intake of 2,000 IU for adolescents, adults, pregnant women and breastfeeding mothers, and 1,000 IU for children may be taken for extended periods during the first 10 years of life with no risk of side effects and without medical supervision.
Most experts consider a daily intake of up to 5,000 IU of vitamin D to be safe for adults.
Since direct sunlight produces 10,000 IU of vitamin D in the human body, this may be the physiological upper limit.
Since vitamin D is potentially toxic, the state-approved limit is 50 mcg . However, this is a conservative limit and is likely 5 times too low.
Known cases of vitamin D toxicity with hypercalcemia in which the 25D concentration and vitamin D dose are known all point to an intake of 40,000 IU a day or more.
Excessive intake of vitamin D can only occur by taking dietary supplements. But one would have to take some 40,000 IU per day for several months to cause vitamin D overdose.
One-time massive-dose therapy involving high doses do not result in an overdose of vitamin D, even at doses in excess of 100,000 IU.
The symptoms of vitamin D intoxication include nausea, high calcium and phosphate levels in the blood, irregular heartbeat and kidney stones.
Vitamin D And Sleep: The Surprising Connection
Vitamin D and sleep quality go hand-in-hand. Early research suggests vitamin D is inversely related to melatonin, your sleep hormone. Increasing vitamin D levels may suppress melatonin levels. So, it makes sense that taking it at night could disrupt your sleep.
That said, you still want to get enough vitamin D because your levels are directly related to the amount and quality of sleep youre getting. Researchers have found that low levels of vitamin D are linked with poor sleep quality. In one study, participants who increased their vitamin D levels saw significant improvement in sleep and neurologic symptoms.
In another study, researchers looked at the vitamin D levels and sleep quality of 3,048 men 68 years and older. They measured total sleep time, wake times and frequency and sleep efficiency, which measures the time spent in bed versus the time spent sleeping. The study found that low levels of vitamin D were linked with poor quality sleep and sleeping less than five hours a night. Low levels of vitamin D were also associated with lower sleep efficiency scores.
We know that vitamin D and sleep quality are linked, but were only really just beginning to understand how and why thats the case. Researchers believe that vitamin D may affect our shut-eye by interacting with the areas of the brain that regulate sleep. We also know that vitamin D plays a key role in supporting the immune system, and managing inflammation may support better sleep quality.
