Coinciding with common belief, it can be quite correctly stated that Vitamin C (ascorbic acid) is an essential nutrient that we should care about. Vitamin C has proven to have various health benefits, as well as benefits for the skin and hair. Discovered in 1912, vitamin C is considered to be one of the safest and the most effective medicinal nutrients that are required by your system. Vitamin C is a water-soluble essential vitamin and cannot be produced by the body. This means that the human body is dependent on food for it. Interestingly, the body cannot easily store it either, and the leftover vitamin C is actually eliminated by the body.

On an average, women need around 70-75 mg of vitamin C on a daily basis, whereas men need around 90-95 milligrams per day. Luckily, vitamin C is available in abundance across a wide range of easily available fruits and vegetables.

Vegetables with the highest amount of vitamin C include green and red peppers, tomatoes, sweet potatoes, broccoli, and cauliflower.

Side-Effects Of Excessive Intake Of Vitamin C

As the natural law states that for every action there is an equal and opposite reaction, we can’t help but wonder that if vitamin C is responsible for being such a beneficial part of our diet, there must be some disadvantages associated with it.

Some of the disadvantages that are associated with the unregulated consumption of vitamin C are listed below:

1. Increase In Iron Consumption

Vitamin C is considered to be an important nutrient that helps in the increased rate of consumption of iron, which is good for health. However, since vitamin C makes it easier for the body to absorb iron, it can sometimes lead to the absorption of an excessive amount of iron, which might have adverse effects on the heart, liver, pancreas, and sometimes may even result in nausea. Keep your vitamin c levels in check to avoid this.

2. Adverse Effects On Our Kidneys

Overloading of vitamin C can cause some severe effects on the kidneys. Vitamin C is a type of antioxidant with is soluble in water; hence it is difficult for our body to store it; excess vitamin C in the body is removed through the urine. However, if the consumption of vitamin C increases the required daily consumption rate, it starts to get accumulated in the kidneys rather than being soluble, which might increase the risk of the formation of kidney stones.

Apart from the above-mentioned side-effects, heavy unregulated consumption of vitamin C can also result in other side-effects that are rather small and rare. Some of these adverse effects of vitamin C include diarrhea, headaches, and muscle cramps.

Signs of Excessive Intake Of Vitamin C
• Diarrhea
• Dizziness or faintness (with the injection only)
• Flushing or redness of the skin
• Headache
• Increase in urination (mild)
• Nausea or vomiting
• Stomach cramps

Symptoms of vitamin C deficiency can start to show after 8 to 12 weeks.

Signs include –

  • Loss of appetite
  • Weight loss
  • Fatigue
  • Irritability
  • Lethargy

Within 1 to 3 months, there may be signs of –

  • Anemia
  • Myalgia, or pain, including bone pain
  • Swelling, or edema
  • Petechiae, or small red spots resulting from bleeding under the skin
  • Corkscrew hairs
  • Gum disease and loss of teeth
  • Poor wound healing
  • Shortness of breath
  • Mood changes, and depression

Treatment involves administering vitamin C supplements by mouth or by injection. Not adhering to the treatment properly can result in prolonged after effects. Within 24 hours of diagnosis and starting the treatment, patients can expect to see an improvement in fatigue, lethargy or laziness, pain, anorexia, etc. Bruising, bleeding, and weakness start to resolve within 1 to 2 weeks. After 3 months, recovery of the deficiency is possible.


The main takeaway from this article about vitamin C, its sources, its uses, and its side-effects, is that the only way you can have an efficient and healthy diet is not just by having a perfect set of food items for your daily consumption, but by also managing responsibly and regulating the diet based on your body’s need.
