But if B vitamins as a group don't seem to bother your sleep and it's more convenient for you to take them in the evening, that should also be fine.

Vitamin C helps your immune system function more effectively and plays a vital role in helping protect your cells from the dangers of free radicals. It's water-soluble, so you don't need to take it with a meal.

The recommended daily amount is 75 milligrams for adult women and 90 milligrams for adult men. However, some people find vitamin C, especially in larger doses, can upset their stomachs and cause diarrhea.

Taking this supplement with a meal can help, and taking a buffered type of vitamin C also can help if you find your digestive system is bothered by it. Vitamin C can help your body absorb iron better , so if a healthcare provider has recommended you take extra iron, you should take your vitamin C at the same time, regardless of what time of day that occurs.

Anecdotally, a few people have reported that larger doses of vitamin C have interfered with their sleep. There's no objective medical evidence for this, but if you're concerned about it, you can take vitamin C in the morning and cut back your dose.

Vitamin D , the "sunshine vitamin," serves many roles in your body. It helps keep your immune system in good shape, it works in conjunction with calcium to build your bones, and your nerves use it to carry messages. Your body makes vitamin D when your skin is exposed to the sun. But because you risk getting skin cancer from excessive sun exposure, you may need to supplement vitamin D if your levels are low.

Vitamin D is best taken with a meal that contains some fat. However, that meal can be breakfast, lunch, or dinner since there's no evidence that vitamin D absorption is better or worse at any particular time.

At least two studies have considered whether taking larger doses of vitamin D can interfere with sleep, regardless of when those doses were taken. One study published in found that women with multiple sclerosis taking high levels of vitamin D—4, IU, or upwards of seven times the recommended daily intake—had lower melatonin levels in their blood.

Women taking IU per day didn't see that effect, and the study didn't evaluate sleep quality, so it's challenging to draw complete conclusions. Another study published in found that older women who were trying to lose weight and taking 2, IU of vitamin D daily because they were deficient saw their sleep quality deteriorate.

The study concluded that this level of vitamin D supplementation could result in poorer sleep quality among post-menopausal women who were already deficient in vitamin D.

It's difficult to say whether you're better off taking vitamin D in the morning or later in the day, although some people report anecdotally that they have better luck with a morning routine. Regardless, very large doses might interfere with sleep, no matter when they're taken.

Vitamin E protects your cells from damage, boosts your immune system, and helps to widen blood vessels and prevent blood clots. Deficiencies can cause nerve damage, vision problems, and a weakened immune system. Take vitamin E with a fat-containing meal.

There's no evidence that taking it at any particular time of day is better or worse for your health. Vitamin K helps your blood clot. It also assists in building strong bones, may protect you from cancer, and fights diabetes by improving your body's sensitivity to the hormone insulin.

Take vitamin K with a meal that contains fat. There's no research showing a "best" or "worst" time of day to take your vitamin K. You've probably heard that calcium builds strong bones and that many people don't consume enough.

Adults and children four and older need between 1, and 1, milligrams of calcium daily. Many people especially those who don't drink much milk or eat calcium-supplemented foods don't get that much. There are different types of calcium and different recommendations for how to take them. Calcium citrate a common form of calcium in supplement products can be taken by itself or with a meal.

Calcium carbonate a less expensive supplement needs the help of stomach acid to break it down, so it's best taken with food. Your body won't absorb more than milligrams of calcium at a time.

So you should divide your dose throughout the day, especially if a healthcare provider has recommended you consume a larger dose daily. Also, you shouldn't take calcium at the same time as an iron-containing multivitamin or magnesium since your body might not absorb it as well.

However, some research published in indicates that calcium may help you fall asleep , and many supplement products combine calcium and magnesium into one often very large pill.

You'll need to decide in consultation with a healthcare professional what's best for you. Finally, calcium supplements can interfere with certain medications, including some types of antibiotics, medicines for osteoporosis, blood pressure medications, antacids, anti-seizure medications, and cholesterol medications.

In some cases, taking calcium can mean your body absorbs more of the medication, while in other cases, your body may absorb less of the medication. Therefore, talking with a healthcare provider about how your prescribed medications might interact with calcium or any other supplement you take is critical.

Magnesium is a mineral that works in your body to regulate nerve function, control blood pressure, and build bone in conjunction with calcium. Most people get enough magnesium, but magnesium deficiency can cause nausea, loss of appetite, fatigue, and weakness. Magnesium can be hard on your digestive system and may cause loose stools.

The popular constipation remedy Milk of Magnesia contains 1, milligrams of magnesium hydroxide, which usually is enough to produce a bowel movement within six hours. If you find magnesium seems to be causing you to have loose stools, try cutting back on your dosage.

A dose of milligrams may be enough for you. Magnesium is best taken at night because it promotes sound, healthy sleep. In people who suffer from leg cramps at night, magnesium also may help to alleviate that problem. Multivitamins combine what researchers consider the most essential vitamins and minerals into one easy-to-take daily pill or, in some cases, several daily pills.

It's common for multivitamins to include vitamin C, some or all B vitamins, vitamins A, D, E, and K, plus minerals such as zinc, selenium, and copper. The use of multivitamins has dropped over the years as more people started to take individual supplements, such as vitamin D.

However, according to a study published in JAMA in , nearly one-third of Americans still took daily multivitamins as of Many people take a multivitamin in the morning, especially if they have other morning medications.

Some of the vitamins in it are most likely fat-soluble, so you should consume them with a snack or meal. Take your multivitamin with food or meal that contains some fat. Some larger multivitamin supplements can cause stomach upset if taken on an empty stomach.

More research is needed to determine how multivitamins affect your sleep, if they do at all, and whether the time of day you take them can impact this.

There just isn't enough information to recommend avoiding multivitamins at night, so you can take them whenever you find it most convenient.

We've tried, tested, and reviewed the best multivitamins. If you're in the market for a multivitamin, explore which option may be best for you. Vitamin and mineral supplements can't help you if you don't remember to take them. Therefore, the best time to take your vitamins is when you will most likely remember to take them.

Many people make taking their vitamins part of their morning routine, and this should work fine, provided your breakfast contains some fat calories. Talk to a healthcare professional if you're confused about what vitamins and minerals to take and when to take them.

They can help you determine which supplements you should take and talk to you about the best time to take them. In addition, you should always let a healthcare professional know if you take any over-the-counter vitamins, minerals, or other supplements since they could interact with medications.

Open Heart. B vitamins are essential for the optimal functioning of many processes in your body. They help your body to form healthy red blood cells and get energy from the food you eat.

Certain B vitamin deficiencies have also been linked to poor mental health. B vitamins are water-soluble, meaning they dissolve in water and are easily excreted by your kidneys. They are more readily absorbed on an empty stomach with water. Most people are hungry upon waking up, so it may best to take your B vitamins in the morning along with some water.

Vitamin C, aka ascorbic acid, is a water-soluble vitamin. Vitamin C is essential for the repair of your tissues, skin, and bones.

Vitamin C also helps your body absorb iron. Additionally, taking vitamin C can also help your body heal wounds more effectively. Also, there's some research to suggest a link between vitamin C and your mood and that antioxidants in vitamin C may be able to adjunctively reduce and prevent anxiety.

If you are not getting enough vitamin C from your diet alone from vitamin C-rich foods like citrus fruits, berries, leafy greens, etc. Given that vitamin C is water soluble, it is best absorbed in the morning with water on any empty stomach.

However, some people experiencing upset with vitamin C, and in that case taking it with meals may be better tolerated. Vitamin D, affectionately known as the "sunshine" vitamin because the sun is a major source of vitamin D, is necessary for several bodily functions.

Often, a vitamin D supplement is necessary for those who live in regions with very little sunlight or people with darker skin complexions. Melanin is a pigment in the skin and hair responsible for dark skin tones and hair. For people with higher amounts of melanin in the skin, it becomes more difficult for the body to synthesize vitamin D in the skin.

Aside from impacting your physical functioning, vitamin D sufficiency has been associated with aspects of your mental health. Scientists have observed that in colder climates, people who don't get sufficient sun exposure are more prone to depression.

Aside from sunlight, other vitamin D sources include:. Given that vitamin D is fat soluble, it is generally felt that taking it with a meal promotes better absorption. However one small study that looked at whether taking vitamin D with foods can aid the rate at which your body absorbs it found that people who took higher dose vitamin D supplements alongside low-fat meals absorbed it better.

Vitamin A is one of the vitamins and micronutrients your body cannot produce. This means you must get it via food or supplements. Vitamin A is vital for many processes in your body, including maintaining the health of your skin, eyes, and gut lining. There are two forms of vitamin A form we consume through our diet and supplements, preformed vitamin A and provitamin A.

Some research shows that including carotenoids in your diet, which are converted to vitamin A in your body may reduce your risk of developing depressive symptoms. As a fat-soluble vitamin, it is best to take vitamin A with a meal, especially one that contains a portion of healthy fats.

The recommended dietary intake for adults is between and micrograms. It is important to note that unlike water soluble vitamins, fat soluble vitamins get stored in the fat in your body, and taking more than required can lead to build up and toxicity.

Vitamin E, an antioxidant that aids in protecting your body's cell membranes, can only be obtained from the foods you eat. For example, you can add vitamin E to your diet via supplements or foods such as:.

Some research shows that low levels of vitamin E have been linked to depression and anxiety. While it's unclear whether supplementation can help with managing symptoms of depression and anxiety, scientists are encouraging further research into the possibility.

These vitamins are designed for people who are pregnant or may become pregnant. Some of the most crucial vitamins for pregnant people are folic acid, calcium, vitamin D, iron, and vitamin A. Research shows that prenatal vitamins play a vital role in aiding the proper brain development of your child and reducing their risk of developing mental disorders.

You can take your prenatal vitamins at any time of day. There are a number of people who rely on vitamin supplements to fulfill their daily nutritional requirements. While taking the recommended doses of vitamin supplements can be helpful, taking high doses is not only ineffective but can be harmful to your health.

An overdose on supplements containing vitamins B or C may only result in temporary side effects, however supplements containing vitamins A, E and D can cause serious adverse effects when used improperly.

Chewable or gummy vitamins are an ideal option for people who either don't like to swallow pills or don't like the taste of vitamin supplements. Taking chewable or gummy vitamins in place of traditional tablets is mostly safe and effective. In a study, researchers compared the efficacy of vitamin C gummy sources with tablet sources.

They found that there was no significant difference in the rate at which the body absorbed both forms, as such they are similarly effective.

Researchers also caution parents against using chewable or gummy vitamins to replace nutritional vitamin sources for their children, as a result of their appeal.

In one study, they observed a wide variation in the dosage of these types of vitamins depending on the supplement, which can be problematic. Many of these supplements also contain a higher dose of vitamins than the daily nutritional requirements for children.

While taking your vitamins is beneficial, consuming it in excess could result in adverse effects. It's common for some people to have an aversion to vitamins. Some people may simply not enjoy the taste, and others could just be stubborn or forgetful.

Vitamin K is needed for blood clotting, bone and heart health, and more. If you choose to take a supplement, they can be found on Amazon. Nevertheless, vitamin K supplements may interfere with certain anticoagulant medications. If possible, take vitamin K separately from the fat-soluble vitamins E and A.

On the other hand, taking vitamins D and K together can be beneficial, as these nutrients work synergistically to promote bone health and healthy calcium levels in your body. Fat-soluble vitamins play many important roles in your body.

Check with your healthcare provider if you have questions about supplementing with these vitamins, as they may not be appropriate for everyone. Multivitamins typically contain a variety of vitamins and minerals. This may enhance the absorption of certain nutrients while reducing the risk of gastrointestinal upset, which can otherwise occur when taking a multivitamin on an empty stomach.

For example, take one pill with breakfast and one with lunch. If you have questions about dosing or how to take your vitamin supplements, consult your healthcare provider for advice. Taking a multivitamin with a meal may help enhance the absorption of certain nutrients and help decrease your risk of digestive issues.

Additionally, timing when you take your supplements will give them the best chance of being properly absorbed — this way they provide the most benefits possible.

Of course, you should always consult your healthcare professional before beginning any new dietary or lifestyle regimen, including taking supplements. You should also always read and follow label directions for product use. The ideal time to take vitamins and minerals really depends on the specific kind.

Some are best absorbed with a meal, while others can be taken at any time of day. This will influence whether you take the supplements in the morning or the evening.

Fats such as olive or coconut oil, whole-fat dairy, nuts, seeds, eggs and avocado can all help your body utilize fat-soluble vitamins.

You can take these vitamins with breakfast or dinner, but you may want to avoid taking them on a completely empty stomach. Ideally in the morning, with water or another beverage, or you can take it with food.

You can and should take B vitamins together such as in a B complex supplement , since they work best when taken together. Any time, with water or another beverage, or you can take it with food.

Even the best quality diet might not be enough to help you meet all of your nutritional needs. Therefore, multivitamins can help to fill in nutritional gaps in your diet if you are unable to meet your needs through your diet alone.

Multivitamins are also often recommended for people following restrictive diets, such as those on low-calorie, low-carb or vegan diets. Overall, multivitamins offer benefits such as support for: bone health, cardiovascular function, healthy immune system function, healthy energy levels, and much more.

Opt for multivitamins made from real food ingredients, which your body recognizes and can use most easily, plus those that feature sprouted and fermented ingredients. Sprouting and fermenting help to partially break down foods so they are even easier to digest.

You can either take your multivitamin in the morning with breakfast, which helps support absorption and is often easier on the stomach, or if you prefer, at night with dinner.

Why do pregnant women benefit from taking multivitamins? Pregnancy is a time in which the body requires extra vitamins, minerals, protein, fats and other nutrients because these help support growth and development of the fetus.

To ensure that mom and baby are getting the nutrition they need in addition to a healthy diet, taking a quality prenatal multivitamin during pregnancy — which contains specialized amounts of vitamins and minerals compared to regular multivitamins — is highly encouraged.

However, you should always consult your healthcare professional. Overall, benefits of prenatal vitamins include support for: general prenatal health, healthy fertility, healthy sleep and energy levels, and healthy blood folate concentrations.

Just like with regular multivitamins, opt for a prenatal supplement that is made with food-based ingredients and no additives or fillers. You can also look for a supplement that contains fermented, methylated or coenzymated forms of nutrients which are designed to support overall healthy absorption and ease on the body.

Generally, you should choose a supplement that provides percent or more of the Daily Value DV of 12 essential vitamins and minerals you need including vitamins A, B, C, D and E, as well as iron, folate, zinc and others.

Because pregnant women can be prone to having sensitive stomachs during this time, some find that taking prenatal vitamins with dinner before bed is the best option.

Pick a time and stay consistent so you easily remember to take your vitamins daily. If you take a multivitamin, you're going to be consuming many different nutrients together. As always, be sure to check with your healthcare professional. Is it better to take vitamins in the morning or at night?

It depends on the kind of vitamin and what your healthcare professional says. Water-soluble vitamins like B vitamins and most minerals can be taken anytime of day, while fat-soluble vitamins vitamins A, E, D, K need to be taken with a meal, either dinner or breakfast, to be absorbed properly. What vitamins should not be taken together?

Some supplements are best taken with a meal that contains some fat. Others may help you sleep better when taken shortly before bedtime. Therefore, the best time for you to take your vitamins will depend on exactly which vitamins you're taking and the health effects you hope to gain from them.

There are a few basic guidelines to follow to get the most out of the vitamins or supplements that you take. Remember to communicate with a healthcare provider about supplement use and seek personalized advice if you are uncertain about the best way to take them.

Some people find that vitamins and minerals can cause upset digestion and even diarrhea if taken on an empty stomach. Therefore, it's generally better to take vitamin and mineral supplements with a meal unless a healthcare provider advises you differently.

To complicate matters further, specific vitamins need to be combined with a meal containing some fat calories. That's because they're "fat-soluble," meaning they only dissolve—and are adequately absorbed by your body—when you take them with some fat. Therefore, taking your vitamins in the morning with an essentially fat-free breakfast perhaps fat-free cereal topped with skim milk could defeat the purpose of consuming the vitamins.

There are also gluten-free vitamins , for those with celiac disease or a gluten intolerance. The time of day can also make a difference in getting the most out of your vitamin or mineral supplement.

Vitamins that may be better when taken in the morning include:. Vitamins and supplements that may be better when taken in the evening, close to bedtime, include:. Here's a rundown of the best times to take specific vitamins and minerals, the best time to take multivitamins, and which supplements should be taken along with some fat calories.

Vitamin A helps to maintain your vision, organs, and reproductive system. There's no evidence that it's better to take vitamin A in the morning or the evening, so take your vitamin A supplement whenever it's most convenient for you.

Vitamin A and beta-carotene are fat-soluble, so take them with a source of fat. Many manufacturers of vitamin A supplements recommend taking the products with a meal. B vitamins—which include thiamine, folic acid, and riboflavin —help your body function properly and stay healthy.

When your levels of certain B vitamins are too low, you might be more tired than you should be. Confusion and anemia can also occur in severe cases, depending on which B vitamins you lack.

Most people take B vitamins as a group , either in a multivitamin capsule or in a specific B vitamin supplement. There's some evidence that specific B vitamins can interfere with sleep.

But different B vitamins may have different effects. Vitamin B Also called pyridoxine, this vitamin may cause vivid dreams and may improve your ability to remember dreams. Researchers in a small preliminary study gave college students very large doses of vitamin B-6 over five days and found their dreams were more vivid, colorful, and bizarre than usual.

You should be able to avoid this problem by taking vitamin B-6 in the morning. Vitamin B helps your body produce energy, and anecdotally. a few people have reported that taking it in the evening makes them too energetic to fall asleep easily.

If you take vitamin B at the same time as your other B vitamins in the morning, you should be fine. It's possible that niacin, also known as vitamin B-3, may help you fall asleep.

Anecdotal evidence indicates that taking a high dose helps some people fall asleep more easily. However, it would be best if you didn't drink alcohol when also taking niacin since alcohol can accentuate niacin's effects, such as flushing. Since you're more likely to enjoy an alcoholic beverage in the evening than in the morning, this may complicate your analysis.

You may be better off taking B vitamins in the morning. But if B vitamins as a group don't seem to bother your sleep and it's more convenient for you to take them in the evening, that should also be fine.

Vitamin C helps your immune system function more effectively and plays a vital role in helping protect your cells from the dangers of free radicals.

It's water-soluble, so you don't need to take it with a meal. The recommended daily amount is 75 milligrams for adult women and 90 milligrams for adult men. However, some people find vitamin C, especially in larger doses, can upset their stomachs and cause diarrhea. Taking this supplement with a meal can help, and taking a buffered type of vitamin C also can help if you find your digestive system is bothered by it.

Vitamin C can help your body absorb iron better , so if a healthcare provider has recommended you take extra iron, you should take your vitamin C at the same time, regardless of what time of day that occurs. Anecdotally, a few people have reported that larger doses of vitamin C have interfered with their sleep.

There's no objective medical evidence for this, but if you're concerned about it, you can take vitamin C in the morning and cut back your dose.

Vitamin D , the "sunshine vitamin," serves many roles in your body. It helps keep your immune system in good shape, it works in conjunction with calcium to build your bones, and your nerves use it to carry messages.

Your body makes vitamin D when your skin is exposed to the sun. But because you risk getting skin cancer from excessive sun exposure, you may need to supplement vitamin D if your levels are low.

Vitamin D is best taken with a meal that contains some fat. However, that meal can be breakfast, lunch, or dinner since there's no evidence that vitamin D absorption is better or worse at any particular time.

At least two studies have considered whether taking larger doses of vitamin D can interfere with sleep, regardless of when those doses were taken. One study published in found that women with multiple sclerosis taking high levels of vitamin D—4, IU, or upwards of seven times the recommended daily intake—had lower melatonin levels in their blood.

Women taking IU per day didn't see that effect, and the study didn't evaluate sleep quality, so it's challenging to draw complete conclusions.

Another study published in found that older women who were trying to lose weight and taking 2, IU of vitamin D daily because they were deficient saw their sleep quality deteriorate.

The study concluded that this level of vitamin D supplementation could result in poorer sleep quality among post-menopausal women who were already deficient in vitamin D. It's difficult to say whether you're better off taking vitamin D in the morning or later in the day, although some people report anecdotally that they have better luck with a morning routine.

Regardless, very large doses might interfere with sleep, no matter when they're taken. Vitamin E protects your cells from damage, boosts your immune system, and helps to widen blood vessels and prevent blood clots. Deficiencies can cause nerve damage, vision problems, and a weakened immune system.

Take vitamin E with a fat-containing meal. There's no evidence that taking it at any particular time of day is better or worse for your health.

Vitamin K helps your blood clot. It also assists in building strong bones, may protect you from cancer, and fights diabetes by improving your body's sensitivity to the hormone insulin. Take vitamin K with a meal that contains fat. There's no research showing a "best" or "worst" time of day to take your vitamin K.

You've probably heard that calcium builds strong bones and that many people don't consume enough. Adults and children four and older need between 1, and 1, milligrams of calcium daily.

Many people especially those who don't drink much milk or eat calcium-supplemented foods don't get that much. There are different types of calcium and different recommendations for how to take them.

Calcium citrate a common form of calcium in supplement products can be taken by itself or with a meal. Calcium carbonate a less expensive supplement needs the help of stomach acid to break it down, so it's best taken with food.

Your body won't absorb more than milligrams of calcium at a time. So you should divide your dose throughout the day, especially if a healthcare provider has recommended you consume a larger dose daily. Also, you shouldn't take calcium at the same time as an iron-containing multivitamin or magnesium since your body might not absorb it as well.

However, some research published in indicates that calcium may help you fall asleep , and many supplement products combine calcium and magnesium into one often very large pill. You'll need to decide in consultation with a healthcare professional what's best for you.
