Vitamin C is one of the most famous and talked about elements. But how many of us really know about the diversity of its actions in body and the importance of daily intake?
Vitamin C is a water soluble vitamin, also known as ascorbic acid. The molecule of vitamin is highly unstable and very sensitive to heat, oxygen, some metals and other compounds (copper, sodium bicarbonate, etc.). The acid name derives from scurvy disease, which was observed in individuals who have a lack of vitamin C.
Normally it is found in a variety of fruits and vegetables, such as peppers, potatoes, broccoli, citrus fruits, strawberries, etc.. While many plants and unicellular microorganisms can synthesize the vitamin from glucose, the human body does not have this capacity, thus making daily intake of vitamin quite necessary.
Deficiency of vitamin
Lack of vitamin C results in a condition called scurvy. Ascorbic acid is a water soluble molecule that is not stored in the body. Main symptoms of vitamin C defieciency are:
• Impaired wound healing
• Destroy of collagen of skin – wrinkles
• Reduced absorption of other ingredients
• Poor quality of hair
Vitamin C is involved in many body functions, including:
• Antioxidant Protection
It is one of the most powerful antioxidants in nature. It has the ability to neutralize free radicals, thus protecting cells from oxidative stress. Additionally, it protects other elements and vitamins from oxidation (e.g. vitamin E). Because of its strong antioxidant action has been linked to many chronic diseases, such as cardiovascular disease and cancer. Moreover it has been found that in combination with bioflavonoids, it is involved in the integrity of vessels.
• Immune System Support
Studies have shown that ascorbic acid mobilizes and stimulates white blood cells while it is also involved in red blood cell production. Moreover, the vitamin participates in the production of antibodies, helping body to quickly recover from viruses, flus, infections or colds.
• Treating allergies
Vitamin C acts as a natural antihistamine. It has the ability to reduce levels of histamine, a hormone that increases in cases of allergic reactions and is responsible for the allergic symptoms.
• Collagen Production
Collagen is a peptide of connective tissue responsible for the integrity and consistency of the skin. Ascorbic acid is a key element for the production of collagen. Thanks to the above property, many gave at Vitamin C the term “anti-aging vitamin” and is widely used in supplements for healthy skin and a cosmetic anti-aging and anti-wrinkle creams for the face.
• Absorption and synthesis of other molecules
Concomitant intake of vitamin C and iron, particularly of non-heme found in plant sources, can up to double absorption. Ascorbic acid is also involved in the biosynthesis of neurotransmitters, hormones of the adrenal gland, L-carnitine and the protein metabolism.
• Wound healing and oral health
As involved in collagen production, obtaining sufficient vitamin C helps in faster healing of wounds and injuries. It promotes growth and tissue repair, improving elasticity and skin consistency.
There is a wide variety of vitamin C supplements in various forms, such as tablets, effervescent tablets, powder or chewable tablets for children. In nature, as in the majority of supplements, exists in the form of ascorbic acid. However, because often cause gastrointestinal problems, there is also another form of vitamin, the esterified form (e.g. calcium ascorbate).
The esterified form is more friendly to people with stomach ulcers, gastrointestinal sensitivity. Furthermore ensures much quicker and better absorption of vitamin (bioavailability) and remains in the blood for a longer time.
The recommended daily dose for adults is 75mg and 90mg for women and men, respectively. People who smoke, because of high oxidative stress, need to take about 35mg of vitamin extra in order to meet their needs.
Contraindications – side effects
As is not stored in the body, the vitamin in large quantities has no toxic effect. However, if there is an overdose, it may cause diarrhea, abdominal pain, nausea and gastrointestinal disorders. As upper daily intake dosage is 2000 mg.
