Overview
Vitamin C, also known as ascorbic acid, is crucial for the proper functioning of many physiological processes, with significant impacts on collagen production, skin health, the immune system, and antioxidant defense.
We need to obtain vitamin C regularly because our body cannot produce it on its own or store it in large amounts. Therefore, a lack of intake over time can lead to deficiency.
In most developed countries, vitamin C deficiency is rare; however, it is estimated to affect one in every 20 people worldwide, particularly those who do not consume enough fruits and vegetables.
In this article, we will explore vitamin C deficiency in depth, including its symptoms, causes, appropriate treatments, and prevention mechanisms. Without further ado, let's get started!
Vitamin C Deficiency Symptoms
The symptoms of vitamin C deficiency can be traced back to three main mechanisms: loss of collagen, poor iron absorption, and a weakened immune system.
The severity of these symptoms depends on the extent of the deficiency, typically appearing about one month after the body stops receiving vitamin C.
In cases of subclinical deficiency, where vitamin C levels are low but not critically deficient, individuals may experience milder symptoms that still impact overall health.
Here are the most common symptoms of vitamin C deficiency:
Scorbutic Tongue: The tongue may look bumpy and glossy with red blotches.
Gum Disease: Swollen, bleeding gums are very common.
Fatigue and Weakness: Feeling unusually tired or weak.
Biofilms and Tooth Loss: Plaque buildup on teeth can lead to tooth loss.
Easy Bruising: Bruises appear more easily due to weakened blood vessels.
Frequent Infections: Increased susceptibility to colds and other infections due to a lowered immune system.
Dry Skin and Hair: Dry, splitting hair and rough, bumpy skin.
Spoon Nails: Nails may become concave and spoon-shaped.
Slow Wound Healing: Cuts and bruises take longer to heal.
Joint Pain and Swelling: Painful, swollen joints due to collagen deficiency.
Iron-deficiency Anemia: Vitamin C is involved in iron absorption.
Irritability and Poor Mood: Vitamin C is involved in neurotransmitters like serotonin and dopamine. A deficiency can cause poor mood, irritability, and could even lead to depression, memory issues, and decreased mental function in severe cases.

What is Scurvy ?
Scurvy is a severe vitamin C deficiency disease historically associated with sailors and others with limited access to fresh fruits and vegetables.
Characterized by symptoms such as fatigue, swollen and bleeding gums, joint pain, and skin issues, scurvy occurs when the body lacks enough vitamin C to maintain healthy connective tissue. This leads to weakened blood vessels, bones, and immune function.
If left untreated, scurvy can result in serious complications, including anemia, severe joint pain, and even death. While rare in modern times, scurvy can still occur in individuals with extremely poor diets or certain health conditions that impair nutrient absorption.
Possible Causes and Risk Factors
Vitamin C deficiency can arise from two main mechanisms: a lack of intake or impaired absorption. Here are the factors that may contribute to vitamin C deficiency:

Possible Causes and Risk Factors
Vitamin C deficiency can arise from two main mechanisms: a lack of intake or impaired absorption. Here are the factors that may contribute to vitamin C deficiency:
☑ Diet Low in Vitamin C
A diet low in fruits and vegetables, which are the primary sources of vitamin C, can significantly contribute to deficiency. This is especially common in individuals who follow a predominantly carnivorous diet.
☑ High Sugar Intake
Consuming high amounts of sugar can contribute to vitamin C deficiency. Glucose and vitamin C share similar chemical pathways for absorption in the body.
Because they utilize the same transport mechanisms, high levels of glucose can compete with vitamin C for absorption, reducing the amount of vitamin C that enters the cells.
☑ Smoking
Smoking generates a large number of free radicals, leading to increased oxidative stress. Vitamin C, being a potent antioxidant, is used up more rapidly to neutralize these free radicals.
Moreover, smoking may impair the absorption of vitamin C in the intestines, leading to lower levels of the vitamin in the bloodstream. The body also utilizes more vitamin C to repair smoking-related oxidative damage.
These mechanisms collectively lead to a higher requirement for vitamin C among smokers, and if not met, can result in a deficiency. As a result, smokers need approximately 35 mg more vitamin C per day than non-smokers.
As a reminder, The general daily recommended intake of vitamin C for non-smoking adults is 75 mg for women and 90 mg for men, whereas smokers should aim for at least 110 mg for women and 125 mg for men per day.
☑ Alcoholism
Excessive alcohol consumption can interfere with the absorption and metabolism of vitamin C. Alcohol can damage the gastrointestinal tract, impairing the body's ability to absorb essential nutrients, including vitamin C.
Additionally, alcohol can increase the excretion of vitamin C through urine, further depleting the body's stores. Poor eating habits, mainly associated with alcoholism, can worsen the deficiency.
It's crucial for those struggling with alcohol dependence to seek help and ensure they receive adequate nutritional support to prevent deficiencies.
☑ Certain Medical Conditions
Certain medical conditions can impair the absorption of vitamin C, leading to a deficiency. Conditions like Crohn's disease, ulcerative colitis, and gluten sensitivity can damage the gut lining, reducing its ability to absorb nutrients effectively.
These conditions cause inflammation and malabsorption in the digestive tract, making it challenging for the body to obtain adequate vitamin C from the diet.
☑ Aging
Aging is a factor in vitamin C deficiency for several reasons. Older adults often consume fewer fruits and vegetables, which are primary sources of vitamin C.
Additionally, nutrient absorption efficiency decreases with age, making it harder to get enough vitamin C from the diet. Chronic diseases and certain medications common in older age can also interfere with vitamin C absorption.
To help prevent deficiency, it's important for older adults to ensure they are getting enough vitamin C through a balanced diet or supplements.
How is Vitamin C Deficiency Diagnosed?
Diagnosing vitamin C deficiency typically involves a combination of medical history, physical examination, and laboratory tests. Here are the key steps:
☑ Medical History
Your healthcare provider will ask about your dietary habits, lifestyle factors (such as smoking and alcohol consumption), and any symptoms you may be experiencing. This information helps identify potential risk factors for vitamin C deficiency.
☑ Physical Examination
A physical exam can reveal signs of vitamin C deficiency, such as swollen or bleeding gums, easy bruising, and skin abnormalities like rough or bumpy skin.
☑ Laboratory Tests
A blood test measuring the level of vitamin C in your blood is the most direct way to diagnose a deficiency. Low levels of vitamin C confirm the diagnosis and help guide treatment.
☑ Additional Tests
In some cases, other tests may be ordered to rule out underlying conditions that could contribute to vitamin C deficiency, such as gastrointestinal disorders like Crohn's disease or ulcerative colitis.
Nota Bene: Early diagnosis is crucial for effective treatment and preventing complications. If you suspect a deficiency, seek medical advice for proper evaluation and care!
Vitamin C Deficiency Treatment
Treating vitamin C deficiency involves addressing risk factors and replenishing the deficiency through dietary changes or supplements, depending on the severity of the deficiency. Here are some key therapeutic aspects:
☑ Boost Your Intake
The first step is to increase your intake of vitamin C-rich foods. Incorporate more fruits and vegetables into your diet, such as oranges, citrus fruits, strawberries, kiwi, bell peppers, and broccoli.
Store and cook vegetables properly to preserve their vitamin C content; for example, steaming or microwaving vegetables can help retain more of their nutrients compared to boiling because excessive heat can destroy vitamin C.
Additionally, try to minimize your consumption of sugar or avoid eating it simultaneously with vitamin C-rich meals or supplements, as sugar competes with vitamin C for absorption.
