How Much is Too Much Vitamin C?
Vitamin C is an essential nutrient that is crucial for maintaining a healthy immune system, skin, and connective tissues. You can obtain vitamin C from a variety of foods or supplements, but like any other nutrient, too much of it can be harmful. Therefore, it’s crucial to understand how much vitamin C is safe and when its consumption becomes excessive.
The Basics of Vitamin C
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that the body can’t produce naturally, and it needs to be taken from external sources. It plays a vital role as an antioxidant in the body, protecting cells from damage caused by free radicals. Additionally, it’s crucial for the formation of collagen, the protein that helps wounds to heal and gives structure to bones, cartilage, skin, and blood vessels.
The daily recommended amount of Vitamin C varies from person to person. While adult males require a minimum of 90mg per day, adult females require a minimum of 75mg per day. Smokers are recommended to consume an additional 35mg per day to help combat the negativity cause by smoking.
Overdoing It
Vitamin C is water-soluble, which means it’s not stored in the body and must be replenished regularly. Consuming excessive amounts of vitamin C, either from foods or supplements, can result in temporary side effects like diarrhea, upset stomach, and cramps. These symptoms usually resolve once the intake is reduced or discontinued altogether.
That said, prolonged or excessive intake of vitamin C can lead to more serious health issues. It can interfere with copper metabolism, causing copper to accumulate in the liver while decreasing its availability in other body tissues that need it. Over Time this can lead to impaired liver functioning. Also, excessive Vitamin C interferes with the body’s natural cell processes and may lead to kidney stones over time.
Factors such as age, sex, weight, and pre-existing medical conditions, or supplement interactions can affect how vitamin C is absorbed in the body, causing more harm in some individuals than others. For example, individuals with kidney problems, iron disorders, and individuals taking Aspirin with Anticoagulants should stick to the recommended daily levels of Vitamin C.
Vitamin C Overdose
Overdosing on vitamin C can cause severe symptoms, including nausea, vomiting, headache, fatigue, and even insomnia. Prolonged excessively high levels of vitamin C can cause damage to bodily tissues as well. Adults who take more than 2,000mg of vitamin C per day have an increased risk of developing kidney stones disease. Additionally, excessive Vitamin C can cause bleeding gums, bruises, joint pain, and iron overload in the body.
Sources of Vitamin C in the Diet
It’s always better to consume essential nutrients directly through the food on your plate rather than resorting to supplements. Vitamin C can be found in a wide variety of fresh fruits, vegetables, and legumes. Some of the commonly available foods with high vitamin C content include citrus fruits, strawberries, kiwi fruit, papaya, tomatoes, broccoli, spinach, and red pepper. Vitamin C also preserves food freshness and is found in many preserved foods such as breakfast cereal.
When preparing your meals, try to use fresh ingredients to balance your vitamin C intake. Avoid boiling vegetables for too long, as heat destroys the vitamin C content. Consuming fruits and vegetables raw or steamed is the best way to preserve their vitamin C content.
Recommended Daily Allowance for Different Age Groups
Age is an essential factor in determining the recommended daily allowance (RDA) for Vitamin C. Newborns shouldn’t consume more than 35mg a day, and infants between 7 and 12 months require 50mg a day. Children between 1 and 3 years old need 15mg per day. By the age of 14, children require 75mg, and adults require a minimum of 90mg per day for men and 75mg per day for adult women. Smokers of any age should consume an additional 35mg per day.
How to Cut Back on Excess Vitamin C Consumption
If you suspect that you’re consuming too much Vitamin C through your diet or supplements, try the following tips:
- Reduce Vitamin C supplement intake- Stop taking Vitamin C supplements unless recommended by a health-care professional.
- Fruit Juice Intake- Opt for fruit juice or High Vitamin C drink.
