If you’re looking for a simple way to boost your immunity and overall health, look no further than vitamin C. Also known as ascorbic acid, this water-soluble vitamin is often associated with immune system support, but it actually has many more health benefits.
Let’s take a look at how Vitamin C positively influences our health, and discover some of the best sources of this essential nutrient. Whether you’re a fruit lover or just looking to improve your health, you won’t want to miss this informative guide.
How Does Vitamin C Benefit the Body?
Vitamin C is an essential nutrient that plays a crucial role in maintaining good health. It is a powerful antioxidant that helps to protect the body from harmful free radicals, which can damage cells and lead to chronic diseases. Vitamin C also supports the immune system by reducing inflammation and fighting off infections.
In addition to its antioxidant properties, Vitamin C is required for collagen synthesis, which is essential for healthy skin, bones, and connective tissue. It also plays a key role in the synthesis of L-carnitine, a chemical needed for metabolism, as well as the formation of certain neurotransmitters and protein metabolism.
Studies have shown that Vitamin C intake is associated with a decreased risk for a variety of chronic diseases, including cancer, autoimmune diseases, cataracts, age-related macular degeneration, rheumatoid arthritis, heart disease, and neurodegenerative diseases like Alzheimer’s and Parkinson’s. Vitamin C has also been shown to help reduce the severity and duration of the common cold and may help to slow down the aging process of the skin.
Incorporating Vitamin C-rich foods into your diet, such as citrus fruits, strawberries, kiwi, broccoli, and peppers, can help to ensure that you are getting enough of this essential nutrient to support your overall health and well-being.
How Much Vitamin C Do We Need Per Day?
To reap the impressive benefits of Vitamin C, it is important to know the recommended daily amounts (RDAs) for adults over the age of 19. According to the National Institutes of Health (NIH), men should aim for 90 milligrams (mg) of Vitamin C per day, while women should aim for 75 mg per day. Pregnant women should consume 85 mg per day, and lactating women should consume 120 mg per day.
It is important to note that excessive amounts of Vitamin C can be harmful to our health. The Tolerable Upper Intake Level (UL) for Vitamin C for all adults is 2,000 mg. Consistently consuming more than this amount can lead to negative health outcomes, as Vitamin C can become a pro-oxidant and contribute to further cell damage.
Common symptoms of excessive Vitamin C intake include nausea, vomiting, diarrhea, and abdominal cramping. Therefore, it is recommended to focus on whole food sources of this antioxidant before turning to supplements. However, it is important to be aware of any Vitamin C that may be present in the supplements you already take.
Here is a summary of the recommended daily amounts for adults over the age of 19:
| Gender | RDA |
|---|---|
| Men | 90 mg/day |
| Women | 75 mg/day |
| Pregnant Women | 85 mg/day |
| Lactating Women | 120 mg/day |
To avoid harmful effects, it is important to consume Vitamin C in recommended amounts and to avoid excessive intake.
