Early Symptoms of Deficiency: The first noticeable signs of vitamin C deficiency include fatigue and weakness, which are related to its role in energy production in mitochondria. However, fatigue is a nonspecific symptom and can have various causes.

Skin Health: Rough, bumpy, and dry skin appears as one of the earliest signs of vitamin C deficiency because vitamin C is essential for collagen synthesis. Collagen is the main structural protein in the skin, and without it, the skin loses its structure and appears aged.

Gum Health: Gum bleeding is a visible sign of vitamin C deficiency due to its importance in maintaining the strength of blood vessels, where collagen is also a key component.

Bruising: Easy bruising occurs because vitamin C deficiency weakens the blood vessels, making them more susceptible to rupture under stress and pressure.

Immune Function: A weakened immune system is another symptom, with increased frequency and severity of colds and infections. Vitamin C is crucial for the production of immune system cells like lymphocytes and neutrophils.

Joint and Limb Pain: Pain in joints and limbs can be a symptom due to the role of vitamin C in collagen stability, which is necessary for joint health.

Red Hair Follicles: This occurs when hair follicles become swollen and red due to bleeding within the follicles, indicating a deficiency.

Natural Sources of Vitamin C: Red bell peppers, oranges, kiwis, broccoli, strawberries, and various other fruits and vegetables are rich in vitamin C and can help prevent deficiency.

Supplementation Benefits and Risks: While supplementation can reduce the duration of common cold symptoms, excessive intake (over 1000 mg daily) increases the risk of kidney stones, especially in people with existing risk factors.

Vulnerable Populations: Smokers, alcoholics, and the elderly are more prone to vitamin C deficiency due to increased oxidative stress, less availability of fresh produce, and absorption issues.
