Vitamin C - what it is, properties, action, deficiency

You think the lemon is the product richest in vitamin C? There is about 100 times more of this vitamin in 100 grams of a cockatoo plum than in a standard lemon. This is valuable knowledge - most mammals produce vitamin C on their own, but humans need to supply it to the body through the diet. Why is its adequate concentration so important? In which products does it occur? What are the symptoms of vitamin C deficiency in the body? Answers to these and other questions can be found in this article.

What is vitamin C?

.

Vitamin C  is a vitamin that is soluble in waterand. Has antioxidant properties - protects the body's cells from free radicals. It influences the wound healing process, is responsible for the immune system and prevents the body from ageing. Vitamin C is essential for the health ofand  every human. 

Left- and right-handedness - what is the difference?

.

Natural and actively biological vitamin C is L-ascorbic acidand. Upon hearing this name, the immediate thought that comes to mind is that it is a left-handed vitamin. This is a mistake. L-ascorbic acid (or vitamin C) is a right-handed compound. D-ascorbic acid, on the other hand, is left-handed. How is this possible?

The letter in front of the name of the acid refers to the spatial configuration of the molecule, not its optical torsion.  Right-handed vitamin C  has the L configuration, which is why it is called L-ascorbic acid. In contrast, left-handed D-ascorbic acid, often referred to as "left-handed vitamin C", is in fact not! This compound, apart from its antioxidant activity, has no biological activity - it has no effect on our bodies.

Where does vitamin C occur in the body?

.

The concentration of vitamin C  in the body ranges from 300 mg (in the case of scurvy) to 2 gand. Its high concentration is maintained in:

.
• cells, 
.
• tissues, 
.
• white blood cells, 
.
• eyes, 
.
• adrenal glands,
.
• brain, 
.

 In contrast, not very much vitamin C is found in fluids such as saliva and plasma. 

Properties of vitamin C

.

Vitamin C influences a number of processes in our body. What are its most valuable properties?

.

Reduces the risk of chronic diseases

.

Vitamin C  is a powerful antioxidant that strengthens the body's defence mechanismsand. The presence of free radicals in the body promotes oxidative stress . This condition leads to numerous  chronic diseases such as amyotrophic lateral sclerosis and Alzheimer's disease . Studies suggest that long-term supplementation  of vitamin C  can increase antioxidant levels in the body by up to 30% . 

Increases immunity

.

Vitamin C  almost everyone associates it with its effect on immunity . It affects the immune system and protects the body from infections. Its deficiency negatively affects health outcomes. Research suggests, that people with pneumonia tended to have lower levels  of vitamin Cand.

Protects memory

.

Dementia, also known as dementia, is a serious disease in which there is a progressive impairment of intellectual functionand. It affects 47 million people  worldwide  and mostly affects the elderly. Patients suffering from dementia not infrequently had lower  levels of vitamin C in their bodies . Furthermore, research suggests that taking vitamin C  positively  affects thinking and memoryand.

Reduces the risk of heart disease

.

Heart disease is  the leading cause of  death worldwideand. A study of more than 293,000 people found that taking more than 700 mg of vitamin C daily for 10 years reduced the risk of heart disease by  25 per cent . Other studiesand suggest, that taking more than 500 mg  of vitamin C  per day for four weeks reduces cholesterol and triglycerides in the blood. 

Omega acids also reduce the risk of heart disease. Want to learn more about them? You are invited to: Omega-3: characteristics, effects, use, types

.

Prevent iron deficiency

.

Iron is an essential nutrient responsible for the production of red blood cells and oxygen transport in the body. Supplements with  vitamin C  improve its absorption from the diet, particularly from plant sourcesand. This is important for vegetarians, as the largest deposits of iron are found in meat. Research suggests that consuming 100 mg of vitamin C improves iron absorption by  67 per cent .

.

Limits uric acid levels in the blood 

.

Too much uric acid leads to goutand. This is a condition manifested by painful inflammation mainly in the big toes. Research suggests that people who consume high doses of vitamin C have lower   uric acid levels in their blood. Furthermore, ascorbic acid supplementation reduces the risk of gout by  44%and. 

Controls blood pressure

.

High blood pressure leads to heart disease - the most common cause  of deathand  worldwide. Preliminary research suggests that vitamin C supplementation  reduces  blood pressure . Although the results are promising, more research is needed to confirm the role of vitamin C in controlling blood pressure. 

Promotes collagen synthesis

.

Vitamin C  is essential for the synthesis and maintenance of collagen in the bodyand. It acts as the "glue" that is responsible for binding collagen fibres together. Vitamin C  in combination with collagen strengthens hair and nailsand.

How else does vitamin C work?

.

.
• Reduces the risk of complications from the flu, such as pneumoniaand.
.
• Limits the likelihood of stroke .
• Prevents skin aging .

Myths about vitamin C

.

Vitamin C has many beneficial properties. However, its popularity has contributed to several myths. Which of these are often repeated, and completely untrue? 

• Reduces cancer risk.   Some people have certainly heard that vitamin C reduces cancer risk. However, this is not true. Studies have shown that vitamin C does not reduce the risk of cancer. 
• Prevents the common cold.   Vitamin C in the eyes of many people is linked to preventing infections. In fact, although vitamin C gently reduces the recovery time for infections, it does not prevent them. 
• Protects against eye diseases.   Cataracts or  macular degeneration  are dangerous eye diseases that vitamin C supposedly prevents . Ascorbic acid supplements do not protect against eye disease. What's more, they may even cause harm to our eyes . 
• Cures lead toxicity.   Some studies have shown that people with lead toxicity have low levels of vitamin C. However, it has not been shown to treat this condition.

In which products is vitamin C found?

.

Vitamin C most of us associate with lemon. Contrary to appearances, this fruit is not at all as rich in it as you might think. Which products contain the most vitamin C?

.

.

What destroys vitamin C?

.

Vitamin C  is lost from foods by excessive heatand. Extended cooking times also negatively affect its content in food. Furthermore, vitamin C is water-soluble, so it often seeps into cooking liquids. If it is not absorbed in this form, its beneficial properties will be wasted.

How to preserve vitamin C in food?

.

Speed heating  and using minimal water are proven methods of preserving vitamin C in foodand. Therefore, frying, blanching or cooking with a small amount of water can preserve vitamin C. However, raw foods are the richest in ascorbic acid. 

Daily vitamin C requirements

.

The amount of vitamin C we should take each day depends on our age. What is the requirementand for vitamin C in children and adults? 

Children

. .

*Nutrition standards for the Polish population

Adults

.

The requirement for vitamin C in adult men is 90 mg per day. In contrast, a daily intake of 75 mg is sufficient for women. Pregnancy and lactation are slightly different. Then 80-85 mg and 115-120 mg should be taken, respectively. A lower dose is sufficient for teenagers, while adult women should opt for the higher dose. 

.

Maximum dose

Vitamin C deficiency

.

Vitamin C deficiency is rare. Most of us provide it with our diet. What leads to a lack of vitamin C in the body? 

.

Cause

.

The availability of fresh produce rich in vitamin C is unproblematic in developed countries. Despite this, vitamin C deficiency still affects approximately  7%  of American adultsand. In addition to poor diet, a lack of vitamin C is also influenced by lifestyle and various medical conditions.

Cause of vitamin C deficiency:

.

• alcoholismand,
.
• smoking ,
.
• anorexia ,
• mental illnesses ,
• dialysis ,
.

Symptoms

.

Most often the body lets us know when something bad is happening. Vitamin C deficiency is no different. When should the red light go on for us? 

Weakened immunity

.

Vitamin C is associated by most of us with immunityand. Ascorbic acid accumulates in numerous  immune cells  to fight infection.  Deficiency of vitamin C  weakens immunity , and increases the risk of illness, such as pneumonia . 

Poor immunity is also affected by vitamin A deficiency. Would you like to read more about it? Take a look at my article: Vitamin A - properties, effects, occurrence, deficiency symptoms

Rough skin

.

Vitamin C  is responsible for the production of collagenand. Called the protein of youth, collagen is responsible for the health of skin, hair, joints and bones. Low levels of vitamin C  lead to skin deterioration . It manifests  follicular keratosis , and also  dries it out .

.

Slower wound healing

.

Limited  collagen production due to vitamin C deficiency leads to slower wound healingand. In extreme cases  lack of  adequate levels of vitamin C  can even result in old wounds opening up . Ascorbic acid deficiency also increases the risk of infection.

Want to know what a lack of collagen in the body results in? Take a look at my article on collagen deficiency!

Weakened bones

.

Vitamin C  deficiency also affects bone healthand. It leads to an increased  risk of fractures , as well as osteoporosis. Vitamin C is responsible for the structure of the bone skeleton. Its deficiency is particularly dangerous for children who are growing and developingand. 

Joint pain

.

Joint pain  is another symptom of vitamin C deficiency linked to collagen . Research suggests that in some cases the pains were so severe that people with vitamin C deficiencies became limp or had  difficulty walking . Furthermore, sometimes there was also bleeding, which caused swelling and additional pain.

Breaking bruises

.

Breaking bruises are the result of bursting blood vessels. Frequent formation  of bruises  is one of the signs  of vitamin C deficiencyand. They can cover large areas of the body or appear as small, purple dots under the skin. 

Gingival bleeding

.

Red, swollen and bleeding gums are another symptom suggesting that your body is demanding vitamin C .  Lack of  adequate levels of ascorbic acid leads to inflammation and weakened gums . In an advanced stage of deficiency, the gums may even appear purple and rotten.

Other symptoms of vitamin C deficiency:

.

• fatigueand,
.
• oxidative stress ,
• worse mood ,
.

.

Vitamin C deficiency results in decreased appetite, poor immunity and broken blood vessels.

Excess vitamin C

.

The body does not produce or store  vitamin Cand. It is therefore very important to provide it daily with the diet. Nevertheless, supplementation with large amounts of vitamin C can lead to negative effects. 

.

If you use higher doses of vitamin C than recommended, this substance can falsify the results of certain tests performed by oxido-reduction methods. These include the determination of blood glucose, creatinine, AspAT and lactate dehydrogenase levels.

. .

Symptoms of excess vitamin C:

.

• headachesand,
.
• diarrhoea ,
• nausea ,
• vomiting ,
• gravity ,
• abdominal pain ,
.

In the long term, excess vitamin C can lead to the development of kidney stones in men, as well as liver problems . Moreover, some studies suggest that too much vitamin C intake from supplements may result in a greater risk of heart disease in postmenopausal women with diabetes .

Vitamin C intake above 2,000 mg per day may, in predisposed individuals, be an initiating factor in the precipitation of oxalate-calcium stones in the urine. This can result in nephrolithiasis. Furthermore, long-term use of high doses of vitamin C in the form of supplements, may result in lower selenium and copper concentrations.

. .

.

Vitamin C - supplementation

.

Most often, vitamin C supplementation is not necessary. Most of us take it with our diet. However, if you think you are deficient in it, it is worth choosing one of the supplements. Remember that healthy supplementation should be recommended by your doctor. 

.

Supplemented vitamin C fights free radicals and also affects the condition of the skin and internal organs. Vitamin C can also be administered in the form of a cream. It then influences the production of collagen. This results in tighter and smoother skin. Vitamin C in this form also affects vascular tightness and fights acne.

.

.

.

Who shouldn't take?

.

.

In people who are prone to stress and also suffer from stomach problems, vitamin C should not be taken on an empty stomach. It can irritate the gastric mucosa, increasing the secretion of gastric acids and consequently exacerbating these complaints. People with stomach problems should be particularly careful when it comes to vitamin C supplementation. More often than not, none of us should take it on our own, without a doctor's recommendation.

. .

What time of day to take it

.

Vitamin C is a very valuable water-soluble nutrient. It is this characteristic that makes it worth taking it in the morning, still on  an empty stomach  (if you have no problems with it)and. It is best to do this about 30-40 minutes before your first meal. This is when you will use the full potential of vitamin C. 

.

Note!

.

Do not use vitamin infusions. Doctors are sounding the alarm that these practices are ineffective and dangerous.

.

People take vitamin C like candy, which is why side effects of vitamin C overdose are often observed. The most common of these is impaired blood clotting. It is over-stimulated, resulting in the formation of clots, which can lead to venous congestion.

. .

.

Vitamin C in pregnancy

.

Vitamin C  is essential for the proper development of pregnancyand. It supports the immune system and also improves the absorption of iron. Furthermore, vitamin C supplementation during pregnancy reduces the risk of complications such as pre-eclampsia and intrauterine growth retardation. Ascorbic acid also prevents anaemia in the mother-to-be. 

Vitamin C and breastfeeding

.

Vitamin C  is one of the components of human milkand. It is one of the main antioxidants. Breastfeeding women should increase their vitamin C intake to 120 mg per day. Most often a healthy diet is sufficient, supplementation is rarely necessary. 

.

Note!

.

Supplementation of vitamin C during pregnancy and during breastfeeding should only be recommended by a doctor.

Vitamin C and alcohol

.

Alcohol   is the seventh leading risk factor for death worldwide.  Long-term  consumption of alcohol negatively affects the absorption of vitamin C by the pancreas . This can lead to inflammation and other conditions of this organ. 

Interactions of vitamin C with drugs

.

Vitamin C may interact with medications. Individuals taking certain medications on a regular basis should exercise caution when taking vitamin C.

Agents reacting with vitamin C:

.

.
• statinsand, 
.
• niacin ,
.
• estrogens ,
.
• warfarin ,
.

.

Vitamin C attenuates the effects of anticoagulants, as well as antipsychotics used to treat schizophrenia and aminoglycoside antibiotics. It does not stop there, it facilitates and accelerates the absorption of certain heavy metals including lead (Pb), cadmium (Cd), copper (Cu) and aluminium (Al), and exacerbates their toxicity.

. .

Caution!

.

If you are taking these or other medications, advise your doctor. Only he or she can recommend a healthy as well as effective supplementation.

.

How to use vitamin C on your face

.

Vitamin C is one of the most powerful antioxidants for slowing down the skin ageing process. The best and safest way would be to use ready-made cosmetics with vitamin C - face creams, eye creams, wrinkle creams or face cheeses.

You can also make your own cosmetics from semi-finished products, but you will find it difficult to get the right concentration.

According to Polish dietary standards, the daily recommended dose for an adult is 75-90 mg per day. It is best to provide it with your diet - you only need to eat about 100g of kale or 50g of yellow peppers.

The maximum daily dose for adults is 2000 mg. Long-term intake of higher amounts can lead to headaches, diarrhoea, vomiting, as well as kidney stones, heart disease or problems with the liver.

.

With what is vitamin C best absorbed?

.

If you want to improve vitamin C absorption, take it along with foods rich in vitamin A, B vitamins, vitamin E, calcium, magnesium, bioflavonoids and zinc.

Does vitamin C cleanse the liver?

.

The properties of vitamin C suggest that it may help to maintain liver health and regeneration - particularly by protecting cells from oxidative stress. Vitamin C supports the production of collagen, which is an important component of connective tissue and forms a protective layer around the organs. In addition, vitamin C helps to cleanse the liver of excess fats. Also check out: Fatty liver - symptoms and treatment

Does vitamin C affect menstruation?

.

Contrary to popular belief, vitamin C does not accelerate or delay your period. However, it can help to alleviate menstrual symptoms. Vitamin C strengthens blood vessels. One study suggests that regular intake of 200 mg of vitamin C and 200 mg of flavonoids resulted in less bleeding during the period in more than half of the women studied.

.

Does vitamin C acidify the body?

.

Regular intake of vitamin C does not acidify the body and does not alter the pH of the blood. However, products rich in vitamin C can acidify the urine. Excess acid formed in food is excreted by the kidneys, which is beneficial for maintaining the acid-base balance in the body. This phenomenon also helps to treat bacterial bladder infections. The bacteria that are responsible for them will not thrive when the pH is lowered.
