Symptoms of vitamin C deficiency

Since vitamin C is incorporated in many vital functions of human body, it’s deficiency leads to an imbalance resulting in the emergence of several symptoms, including:

 Vitamin C is involved in the synthesis of collagen, which is a protein utilized by the hair, skin, and joints.

A change in hair texture is a distinguishing sign of a lack of vitamin C, but it is usually difficult to detect as this type of unhealthy hair quickly falls out.

  • Bright Red Hair Follicles:

A person might also note the appearance of red spots next to the hair follicles. This effect appears predominantly because vitamin C maintains the small capillaries that nourish the hair follicles. It’s deficiency may lead to bursting of these capillaries which appear as red spots on the surface of the skin next to hair follicles.

This symptom is known to be one of the signs of anemia, but it also prevails in cases of vitamin C deficiency. Some people with vitamin C deficiency might note the appearance of white or red spots on their nails as well.

  • Dry skin:

 Direct sunlight exposure in people with vitamin C deficiency may worsen oxidative damage and lead to even drier, more damaged skin.

  • Easy bruising from light blows:

Vitamin C is involved in collagen production therefore it’s deficiency leads to weak blood vessels due to reduced collagen production resulting in bruises on the skin.

  • Joint pain and swelling:

Vitamin C is involved in collagen production, which is essential for healthy joints and bones, thus its deficiency may lead to joint stiffness.

  • Gum disease:

Red tinted gums in addition to bleeding gums are telltale signs of vitamin C deficiency. Severe vitamin C deficiency can even lead to tooth loss.

Vitamin C for Colds:

Some studies have shown that consuming vitamin C led to a reduction in the duration of colds during an active infection as well as symptomatic relief associated with it.

Vitamin C and the Heart:

Several studies have shown that vitamin C may reduce elevated systolic and diastolic blood pressure readings. While other research has shown that vitamin C may reduce the levels of cholesterol and triglycerides in the blood. Blood pressure and hyperlipidemia are among the most dangerous conditions leading to heart diseases therefore consuming vitamin C may reduce this devastating risk.
