Vitamin C and Sleep – Can This Sour Citrus Be Your New Sleep Superhero?
What is vitamin C?
So, first things first, what do we have to know about this βfamous' vitamin C?
Well, the first thing we should know is that this vitamin is a water-soluble vitamin, also known as ascorbic acid. And, as such,Β it plays a vital role in various bodily functions. Moreover, vitamin C is an essential nutrient, meaning that our bodies cannot produce it on their own. Rather, we need to obtain it through our diet or supplements.
Vitamin C is involved in several biological processes, including collagen synthesis, immune health, wound healing, and antioxidant protection. It is found in many fruits and vegetables, such as citrus fruits, strawberries, kiwi, broccoli, bell peppers, and spinach. However, we will talk about this in more detail later on.
What are the benefits of vitamin C for sleep?
According to Sean Buyers fromΒ Health Report Live, βthere is some evidence to suggest that vitamin C may have a connection to sleep quality. Vitamin C is an antioxidant vitamin that helps to protect the body from oxidative stress, which can be caused by factors such as pollution, smoking, and poor diet. It is also involved in the production of neurotransmitters like serotonin, which can affect mood and sleep.'
Vitamin C has several benefits for sleep, including:
- Promoting relaxation: Vitamin C is a natural sedative. It helps calm the mind and body, making it easier to fall and stay asleep.
- Regulating cortisol levels: Cortisol is a stress hormone that can interfere with sleep. Vitamin C helps to regulate cortisol levels, reducing stress and promoting better sleep.
- Improving sleep quality: Vitamin C has been shown to improve poor sleep quality. Also improves the amount of time spent in the restorative REM phase of sleep.
- Reducing inflammation: Inflammation can disrupt sleep, and vitamin C has anti-inflammatory properties that can help to reduce inflammation and improve sleep quality.
- Boosting the immune system: Adequate levels of vitamin C are supporting the immune function of our bodies. It can reduce the risk of infections and illnesses that may interfere with sleep.=
So, yes, if you have enough vitamin C levels in your body, you will have a restful sleep tonight and every night to come!
However, let us get something clear β vitamin C can contribute to sleep health. However, this vitamin alone can't fix your poor sleep quality and all of your sleep disorders! To fix your sleep disorder, whatever that disorder may be, you have to pair vitamin C with a healthy diet. It also goes with physical exercise, reduced stress, and some other vitamins (such as vitamins e, d, b, etc.).
Other benefits of vitamin C
However, vitamin C does not only contribute to improved sleep quality but also to our physical and mental health!
Vitamin C intake has several important benefits for overall health, including:
- Improving iron absorption: Vitamin C enhances the absorption of iron from plant-based foods, which can help to prevent iron deficiency anaemia.
- Acting as an antioxidant: Vitamin C is a powerful antioxidant that helps to protect cells against damage from harmful free radicals.
- Promoting wound healing: Vitamin C is necessary for collagen synthesis, which is essential for wound healing and tissue repair.
- Supporting healthy skin: As previously said, vitamin C helps to promote the production of collagen. Collagen can improve the appearance of the skin and reduce the signs of ageing.
- Helping with bone health: Collagen is also essential for our healthy bones.
- Reducing the risk of chronic diseases: Vitamin C has been associated with a reduced risk of chronic diseases such as cardiovascular disease, stroke, and certain types of cancer. Vitamin C can also help with high blood pressure and congested blood vessels.
- Improving mood: Vitamin C has been shown to improve mood and reduce symptoms of anxiety and depression, especially in young adults.
Foods rich in vitamin C
Vitamin C is found in many fruits and vegetables, so, incorporating it into your diet is relatively easy.Β Some of the best sources of vitamin C include citrus fruits, such as oranges, lemons, and grapefruit.Β One medium-sized orange contains about 70 mg of vitamin C, which is more than the recommended daily intake for adults. Other citrus fruits, such as grapefruit and tangerines, also contain high levels of vitamin C.
Berries are another excellent source of vitamin C, with strawberries and raspberries containing particularly high levels of nutrients. One cup of strawberries provides more than 100% of the recommended daily intake of vitamin C. One cup of raspberries contains about 50 mg of vitamin C.
In addition to citrus fruits and berries, many vegetables are also rich in vitamin C. Bell peppers, for example, contain more vitamin C than most citrus fruits. A medium-sized red bell pepper contains about 150 mg of vitamin C. A medium-sized green bell pepper contains about 95 mg. Other high vitamin C vegetables include broccoli, brussels sprouts, and spinach.
Thus, if you have vitamin C deficiency (lower vitamin C levels), try to incorporate some fresh fruits and vegetables into your diet. Even a single piece of fresh fruit a day can make a huge difference. Do this before you opt for vitamin C supplementation!
Can you get this vitamin through supplementation?
Yes, vitamin C can also be obtained through supplementation. Vitamin C supplements come in various forms, including tablets, capsules, chewable tablets, powders, and gummies.
While it is always best to get nutrients from whole foods, vitamin C supplements can be a convenient and effective way to ensure you meet your daily requirements.
It's always a good idea to speak with a healthcare professional before starting any new supplement regimen. That's especially if you have any medical conditions or are taking prescription medications, as vitamin C supplementation can interact with some medications.
How much vitamin C do you actually need?
The recommended daily intake of vitamin C varies depending on age, gender, and other factors such as pregnancy and smoking status. For most healthy adults, the recommended daily intake of vitamin C is between 75-120 mg per day. However, some individuals may require higher doses, such as smokers, who have increased oxidative stress and therefore may require up to 250 mg per day.
For pregnant and breastfeeding women, the recommended daily intake of vitamin C is slightly higher, at 85-120 mg per day. This is because vitamin C plays an important role in fetal development, and insufficient intake of the nutrient during pregnancy can lead to complications such as low birth weight and preterm birth. Additionally, breast milk is a source of vitamin C for infants, so breastfeeding mothers need to ensure they are getting enough of the nutrients to support their own health as well as that of their baby.
It is important to note that while vitamin C is a water-soluble vitamin and excess amounts are excreted in the urine, too much vitamin C can cause gastrointestinal discomfort and diarrhoea. Therefore, it is generally best to aim for the recommended daily intake rather than excessively high doses, unless advised to do so by a healthcare professional for a specific medical condition.
The side-effects of vitamin C
While vitamin C is generally considered safe and well-tolerated when taken in appropriate doses, taking excessive amounts of the nutrient can lead to side effects.
Some of the most common side effects of taking high doses of vitamin C include gastrointestinal discomforts, such as diarrhoea, nausea, and abdominal cramps. These symptoms usually occur when amounts exceed 2,000 mg per day, although individual tolerance may vary.
In addition, taking very high doses of vitamin C over a long period of time may increase the risk of developing kidney stones, particularly in people with a history of kidney disease or other risk factors for kidney stones.
Some individuals may also be allergic to vitamin C or certain forms of the nutrient, such as ascorbic acid. Symptoms of an allergic reaction to vitamin C may include hives, itching, swelling, and difficulty breathing.
Some of the best vitamins for sleep quality
In addition to vitamin C, several other vitamins can also play a role in promoting adequate sleep. Here are a few examples:
- Vitamin D: Adequate vitamin D levels have been associated with better sleep quality, and vitamin D deficiency has been linked to sleep disturbances. Vitamin D is produced by the body in response to sunlight exposure, but it can also be obtained through foods such as fatty fish, egg yolks, and fortified dairy products.
2. Vitamin B6: Vitamin B6 is involved in the production of the neurotransmitter serotonin, which helps regulate sleep-wake cycles. Foods rich in vitamin B6 include poultry, fish, potatoes, bananas, and chickpeas.
3. Magnesium: Magnesium plays a role in promoting relaxation and reducing stress, which can improve sleep quality. Good dietary sources of magnesium include nuts, seeds, legumes, whole grains, and leafy green vegetables.
4. Melatonin: Although not a vitamin, melatonin is a hormone produced by the body that regulates sleep-wake cycles. Melatonin supplements may be helpful for some people who have trouble falling asleep or staying asleep (and those who have various sleep disorders).
It's worth noting that while vitamins and other nutrients can play a role in promoting good quality sleep, they are not a substitute for good sleep hygiene practices such as maintaining a consistent sleep schedule, avoiding caffeine and alcohol before bedtime, and creating a comfortable sleep environment.
So, once again β if you have trouble sleeping, it's always a good idea to speak with a healthcare professional to rule out any underlying medical conditions and determine the best course of treatment.
Conclusion
In conclusion, vitamin C is an essential nutrient that plays a vital role in many functions of the body, including promoting enough quality sleep. Adequate intake of vitamin C from dietary sources or supplements may help regulate sleep-wake cycles, reduce inflammation, and alleviate stress, all of which can contribute to better sleep quality.
However, it's important to remember that vitamin C is just one piece of the puzzle when it comes to promoting healthy sleep habits. Maintaining a regular sleep schedule, practising good sleep hygiene, and managing stress levels are all crucial factors in achieving restful and restorative sleep.
