Importance of Vitamin C For Our Health, its Benefits, and Side Effects of Excessive Intake of Vitamin C

Vitamin C is an essential nutrient for our body. It helps in the formation and maintenance of blood vessels, skin and bones. This vitamin is water-soluble and is not stored by our body. You should have vitamin C rich food on regular basis to avoid its deficiency. It is found in an ample amount in some fruits and vegetables. Supplements of vitamin C are also available in the market if you are not able to take it through the diet.(1)

How Important is Vitamin C For Our Health?

Our body requires this vitamin to do different functions.

Vitamin C helps our body in producing L-carnitine, collagen and some neurotransmitters. It is also an antioxidant and helps in getting rid of unwanted substances known as ROS (Reactive Oxidative Species) from our body. To your knowledge, ROS are substances like free radicals due to natural bodily processes, pollution, and other factors like that. These substances cause oxidative stress resulting in cell damage.

Our body requires vitamin C for the production of collagen. It makes up 1–2% of the muscle tissue. Collagen is an essential component in the fibrous tissues like:

  • Bones
  • Tendons
  • Cartilage
  • The gut
  • The cornea
  • Skin
  • Blood vessels
  • Ligaments(1,3)

  1. Vitamin C Helps Boost Our Immune System:

    Vitamin C is well known for boosting our immune system. If one is suffering from a cold, he/she is advised to take Vitamin C rich food, this is because of the positive health effect of this wonderful vitamin on our immune system.(4)

  2. Vitamin C Helps Improve Cardiovascular Health:

  3. Antioxidant Properties of Vitamin C to Make Our Skin Healthy:

    Vitamin C is a powerful antioxidant that has been used for ages in the skincare industry to heal various skin related problems. Owing to its antioxidant properties, Vitamin C helps fight free radicals and due to this quality, it is a common ingredient in many skin care products like face creams, face packs, masks, moisturizer, etc. These vitamin C infused products leave a radiant glow on the skin.

    If your vitamin C consumption is low, your body’s wound healing process may be slow due to the less production of collagen. As discussed before, collagen is present in our muscles, skin and other tissues. This is why doctors and healthcare experts recommend taking vitamin C rich food or supplements during recovery.(7,8)

Side Effects of Over-consumption of Vitamin C

Even though the level of toxicity of vitamin C is less, high intake can still be harmful to some people. They may experience mild side effects like digestion problems.
