Benefits of Vitamin C

Have you wondered what are some of the benefits Vit C brings to us?

  1. Cardiovascular health

Vitamin C is beneficial as its consumption improves cardiovascular health. It may lower blood pressure in those both with and without high blood pressure. A study discovered that in adults with existing high blood pressure, increased vit C intake reduced systolic blood pressure by 4.85 mmHg and diastolic blood pressure by 1.67 mmHg, on average.

In addition, another study found that people with the highest concentrations of vit C in their blood had a 42% lower risk of stroke than those with the lowest concentrations. This meta‐analysis also suggests significant inverse relationships between dietary vitamin C intake, circulating intake, and risk of stroke.

  1. How does Vitamin C help your skin?

Another of vitamin C’s benefits is that it contributes to skin health. Healthy skin contains large amounts of vitamin C. A study published in the American Journal of Clinical Nutrition found among that women aged 40-74, higher intakes were associated with better skin-aging appearance.

Other studies also show that less dryness and a lower likelihood of a wrinkled appearance are linked to high C consumption. As a naturally-occurring antioxidant, vitamin C keeps skin healthy by protecting it from oxidative damage caused by the sun and exposure to pollutants like cigarette smoke or the ozone. Furthermore, it also promotes collagen production, which keeps skin looking plump and youthful and prevents developing dry, wrinkled skin.

  1. Vitamin C intake prevents Scurvy

A lack of vitamin C in the diet leads to a disease known as Scurvy. Without sufficient C, humans lack the nutrients to make building blocks for collagen, which contributes to other problems. Early symptoms include weakness, feeling tired, and sore arms and legs. Following that, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As Scurvy worsens there can be poor wound healing, personality changes, and finally, death from infection or bleeding.

Much more prevalent in the past, scurvy has been documented as early as the time of ancient Egypt. It would kill large numbers of people during long distance sea travel. During the age of sail, it was assumed that 50% of sailors would die of scurvy on each trip. Subsequently, citrus fruits high in vitamin C was discovered to be effective in treating and preventing Scurvy.

Today, Scurvy is rare, and occurs much more in the developing world where there is malnutrition. Treatment involves oral consumption of vitamin C supplements. A diet with consistent intake of the nutrient prevents Scurvy from occurring.


  1. Promotes better memory and improves cognitive function

Vitamin C promotes better memory and fights against dementia. Dementia is a broad term used to describe symptoms of poor thinking and memory. The most common type of dementia is Alzheimer’s disease,

In 2011, researchers from Lund University found that vit C helps combat Alzheimer’s disease. It dissolves the toxic protein that accumulates in the brain with Alzheimer’s. Ordinarily, Alzheimer’s causes a build-up of plaque that contributes to nerve cell death. The cells that die the fastest when this occurs are the memory cells.

In addition, upon reviewing past studies, researchers from Vanderbilt University Medical Center discovered it is the antioxidants found in vitamin C that were usually identified as the beneficial compounds in fighting brain oxidation and memory loss.

This article also supports the notion of the link between vitamin C and cognitive functions like memory, lingual skills, calculation, and orientation. Researchers from Australia found that people with dementia and Alzheimer’s disease have low levels of the nutrient in their blood. Some researchers assume that older people who have developed dementia often have difficulty with getting a healthy diet that covers their need.

Vitamin C Deficiency

What are some symptoms of vitamin C deficiency?

Vitamin C deficiency shows itself in various ways in our bodies. As mentioned earlier, long term deficiency leads to the condition Scurvy.

While Scurvy is very rare today, our body responds in other ways. Some of these symptoms include:

  • Anemia
  • Gingivitis (inflammation of the gums) & Bleeding gums
  • Decreased ability to fight infection and wound-healing rate
  • Dry and splitting hair
  • Easy bruising
  • Nosebleeds
  • Possible weight gain because of slowed metabolism
  • Rough, dry, scaly skin
  • Swollen and painful joints
  • Weakened tooth enamel


What are some Vitamin C rich foods?

It’s important to have Vit C rich foods in our diet, especially since the human body does not produce any of it.

The Recommended Daily Amount as suggested by the Health Promotion Board is 105mg and 85mg per day for adult males aged 18 years and above and females aged 19 years and above, respectively.

How much is 90mg of vitamin C? That amount can be roughly found in:

  • 8 bananas
  • 1 1/3 oranges
  • 10 apples
  • 1 1/3 kiwi fruits
  • 4 tomatoes

Why is consumption of Vitamin C tablets recommended?

Vitamin C supplements are available in many forms, such as tablets or capsules. These provide much needed convenience to people today. It is not practical for people to consume required servings of fruit and vegetable consistently to ensure sufficient nutrients and mineral consumption. Supplements and tablets are a effective and safe substitute, thus allowing our bodies to receive what they need on a daily basis.

Supplements typically contain 500-1000 mg of Vitamin C, more than the recommended daily requirement. Side effects usually only occur after an overdose of 2000 mg.
