In this article, you will find information about:

• Indeed, vitamin C and ascorbic acid are the same substance. Ascorbic acid is the chemical name for vitamin C, which plays an important role in the body, participating in various biochemical processes.
• There are certain signs that may indicate a vitamin C deficiency. One of the most noticeable symptoms is chronic fatigue and a general feeling of weakness. You may also notice the appearance of bruises that occur for no apparent reason, which is associated with the deterioration of the blood vessels.

  Other characteristic manifestations include skin problems such as dryness, peeling, and delayed wound healing. People with vitamin C deficiency may also experience dental problems, including bleeding gums. In addition, it is not uncommon for there to be an increased susceptibility to infections, which is associated with a weakened immune system.

  If you notice similar symptoms in yourself or your loved ones, you should pay attention to your vitamin C levels and, if necessary, consult a specialist.

  19. Lingonberries
  20. Plums
  21. Strawberries
  22. Peaches

  These foods can help provide the body with the necessary amount of vitamin C, which plays an important role in maintaining health.

• How to properly store these foods:
• There is a belief that vitamin C can help prevent and treat colds. However, scientific research shows that its effectiveness in this regard is not so clear. Some studies indicate that regular vitamin C intake may slightly reduce the likelihood of developing a cold, especially in people who are exposed to intense physical activity. However, once a cold has already occurred, vitamin C supplementation does not significantly shorten the duration of the illness or relieve symptoms. Therefore, vitamin C may have certain benefits, but you should not rely on it as a primary treatment for a cold.
• Can you reach your daily requirement for vitamin C through your regular diet?
• High doses of vitamin C can pose health risks. Although this vitamin plays an important role in maintaining the immune system and overall health, too much of it can lead to unwanted effects. Taking too much vitamin C can often cause digestive upset, including diarrhea and nausea. Furthermore, excessive consumption can lead to kidney stones, especially in people predisposed to this condition. Therefore, it's important to follow the recommended intake and consult a doctor before taking supplements.

Similarities Between Vitamin C and Ascorbic Acid: Explaining the Term

Vitamin C is a water-soluble vitamin that we absorb through plant foods. In nature, it is primarily found as L-ascorbic acid, making it synonymous with vitamin C.

The word "ascorbine" comes from the Latin expression meaning "absence of scorbutus." Scurvy, in turn, is a disease that occurs as a result of a lack of vitamin C. Interestingly, scurvy is also known as scurvy, which is why ascorbic acid was long perceived not as a vitamin, but as a remedy for scurvy.

Definition of scurvy and the relevance of its danger in modern times

Scurvy arose among sailors who went on long voyages and ate only canned foods. Their diet did not contain vegetables and fruits, which are the main sources of vitamin C, which soon led to the emergence of various health problems after the start of the voyage:

The main manifestations of scurvy include:

• The gums become swollen, turn red and begin to bleed.
• Blood vessels in the mucous membrane of the eye rupture.
• Wound healing is very slow.
• Joint pain can occur as a result of the accumulation of blood in the joint cavity.
• Teeth can fall out as a result of the destruction of the tissues surrounding them.

The doctor James Lind was the one who was able to solve the problem of scurvy. His desire to find an effective remedy was so strong that he approached his task as a true scientist. Lind organized an original experiment in which he divided sailors suffering from the disease into several groups and included various products in their diet - vinegar, garlic, mineral water and lemons. Over time, the first results began to appear: only those who consumed lemons remained healthy. This study was essentially the first example of a scientific approach in medicine, which is now commonly called a randomized placebo-controlled trial.

Despite the fact that Dr. Lind published his work under the title "Treatment of Scurvy," his research went virtually unnoticed. For 48 long years, British sailors continued to eat canned food, and scurvy continued to claim lives. However, one man decided to believe in Lind's ideas: the famous Captain James Cook. Preparing for his next voyage, he filled his holds with lemons. The result was impressive: throughout his entire expedition, not a single sailor died from scurvy.

Signs of Vitamin C Deficiency in the Body

Scurvy is virtually unknown these days, but cases of hypovitaminosis and pre-hypovitaminosis are becoming quite common—this is the initial stage of vitamin deficiency. It can be identified by a number of characteristic signs:

• general weakness;
• irritability;
• weight loss;
• discomfort in the muscles and joints.

The symptoms in question are nonspecific, meaning they can indicate a variety of diseases or conditions, including simple fatigue. However, if the symptoms persist after rest, it makes sense to consider whether you are getting enough vitamin C from your diet.

Why do we need vitamin C

Most people are aware that ascorbic acid helps strengthen the immune system, but it is worth noting other beneficial qualities of the vitamin C. Here are six significant functions that ascorbic acid performs:

• Vitamin C acts as an antioxidant, acting as a defense mechanism capable of neutralizing harmful free radicals and preventing their destructive effects on cellular structures. In addition, due to its properties, ascorbic acid helps the body fight various toxic substances, such as nitrosamines, arsenic, cyanides, lead, and benzene, which can enter the body through food, air, or water.
• Immune cells are activated in a special way. In particular, there is a unique group of cells known as neutrophils, which are the first to respond to inflammatory processes in tissues. Research indicates that neutrophils significantly accumulate vitamin C, which contributes to their ability to more effectively perform their functions: capturing viruses and bacteria, as well as clearing tissues of unwanted particles.
• Vitamin C has the ability to restrain viral infections. Studies show that it can help increase the production of interferon, which is an important means of protecting cells from viruses. This effect is especially pronounced in cases of influenza virus infection.
• Vitamin C plays an important role in the blood clotting process. Under normal conditions, its level in the body remains low, but when there is an excess of free radicals, it can reduce excessive clotting. At the same time, some studies indicate that excess vitamin C can, on the contrary, promote the formation of blood clots.
• Collagen synthesis plays an important role in the body, since approximately one-third of all proteins are collagen structures. It provides tissues with both strength and elasticity. The process of collagen formation is carried out by specialized cells known as fibroblasts. However, without sufficient levels of vitamin C, this process can be disrupted.
• Ascorbic acid promotes more efficient absorption of iron. It converts ferric iron found in food into ferrous iron, making it more available to the body.

In addition, researchers have found that ascorbic acid acts as a cofactor for enzymes involved in the production of neurohormones such as norepinephrine (responsible for wakefulness), dopamine (supporting motivation), and serotonin (causing a feeling of satisfaction) [11].

Who is susceptible to vitamin C deficiency?

Vitamin deficiency can affect anyone, but certain categories are especially vulnerable. The US National Institute of Health (NIH) identifies four such groups that should be given special attention.

1. Smokers

Cigarette smoke contains many substances that contribute to increased oxidative processes in the body. This leads to rapid depletion of vitamin C reserves. As a result, smokers need to get 35 mg more ascorbic acid per day compared to those who do not smoke.

2. Children who drink cow's milk

Breast milk and specialized formulas provide the body with a sufficient amount of vitamin C. At the same time, whole cow's milk contains almost no this important vitamin. In addition, the pasteurization process, in which milk is heated to destroy pathogens, leads to the destruction of vitamin C.

3. Adults and children with a monotonous diet

Lack of variety in the diet, the dominance of fast food and a small amount of fresh vegetables and fruits can lead to vitamin C deficiency. This is especially true for the elderly, who often choose only familiar foods.

4. Individuals suffering from long-term illnesses.

Chronic diseases, especially those affecting the digestive system, can negatively affect the normal absorption of vitamin C. Such diseases include, for example, irritable bowel syndrome, also known as "bear stool", as well as various types of food intolerance. In some cases, the absorption of ascorbic acid is impaired by certain medications, particularly antibiotics.

The optimal daily dose of vitamin C for the body.

The daily requirement for vitamin C varies depending on a person's age and gender. According to the information provided by the US National Institutes of Health, the recommended intake of vitamin C is as follows:

Pregnant women need 85 mg, while for those who are breastfeeding, the daily requirement increases to 120 mg.

22 Nutrient-Dense Sources of Vitamin C

Humans do not produce the enzyme L-gulonolactone oxidase, which plays a key role in the formation of vitamin C. In this regard, ascorbic acid can be obtained either from plant foods or through dietary supplements.

Ascorbic Acid Content in Various Foods [1]

Optimal Storage Conditions for Foods Rich in Vitamin C

Vitamin C is highly sensitive and subject to destruction. However, by understanding a few important nuances, you can significantly extend its shelf life in food products.

• The temperature at which food is cooked significantly affects the vitamin content. Frying and boiling can destroy up to 90% of vitamin C. For example, if you cook cabbage in soup, the loss of vitamin C will be about 50%. Stewing, on the other hand, will preserve approximately one-third of the ascorbic acid. Therefore, to ensure sufficient vitamin C intake, it is recommended to consume more raw vegetables and fruits.
• The duration of cooking directly affects the vitamin C content of foods. The longer the cooking time, the more of this important vitamin is lost. For example, peeled potatoes can lose up to 50% of their vitamin C during cooking. However, if you immediately place them in boiling water, you can significantly preserve more of its beneficial components.
• Shelf life of foods. If vegetables, fruits, or berries are stored for more than 2-3 months, their vitamin C content is reduced by approximately half. This occurs due to the action of the enzyme ascorbinase, which acts as an antivitamin. However, fresh and sauerkraut are an exception, as their vitamin C content is retained longer.
• Sunlight. When fruit is dried in the sun, the vitamin C content is almost completely lost, resulting in dried fruit lacking ascorbic acid.

Freezing does not destroy vitamin C; on the contrary, it helps preserve it. For example, if you compare fresh spinach that has been refrigerated for several days with frozen spinach, the frozen version will contain more ascorbic acid.
