  • What is vitamin C?

    Vitamin C , also known as ascorbic acid, is a water-soluble vitamin found naturally in many foods. It is essential for the proper functioning of the body because it plays an important role in the production of collagen, a key component of connective tissue that helps maintain healthy bones, teeth and skin.

    It is also a powerful antioxidant that protects cells against damage caused by free radicals. The latter are responsible for cellular aging and the appearance of various chronic diseases. Additionally, it plays an important role in maintaining a healthy immune system by stimulating the production of white blood cells.

    Vitamin C and its health benefits

    This vitamin is known for its antioxidant properties that protect cells against damage caused by free radicals, unstable molecules that can damage DNA and healthy cells.

    It is also beneficial for strengthening the immune system. Studies have shown that vitamin C can increase the proliferation of immune cells, making it an effective immune booster. Vitamin C deficiency can also weaken the immune system, which can increase the risk of infections and diseases.

    Vitamin C also plays an important role in the formation of collagen, a protein essential for healthy skin, teeth, cartilage and bones. By contributing to the normal formation of collagen, vitamin C can help maintain the health of the body's connective tissues.

    In addition to strengthening the immune system and promoting collagen formation, vitamin C also helps protect cells against oxidative stress. Free radicals can cause cellular damage which can lead to various chronic diseases. As an antioxidant, vitamin C can help neutralize free radicals and protect cells from damage.

    Finally, vitamin C is also important for normal psychological functions. It can help maintain positive mood and healthy cognitive function. Studies have shown that people with higher vitamin C levels have fewer symptoms of depression and anxiety.

    In sum, vitamin C has many health benefits, such as strengthening the immune system, promoting skin and connective tissue health, protecting against oxidative stress, and promoting healthy psychological function. . It is important to maintain adequate vitamin C intake to reap these benefits.

    Symptoms and causes of vitamin C deficiency

    Vitamin C is an essential nutrient for the human body, and a deficiency of this vitamin can have negative health effects. Deficiency symptoms may vary depending on its severity, but may include persistent fatigue, muscle weakness, loss of appetite, weight loss, muscle and joint pain, bleeding gums, dry, scaly skin. , and increased susceptibility to infections.

    The main causes of vitamin C deficiency are insufficient diet of fresh fruits and vegetables, as well as factors such as alcoholism, intestinal malabsorption, chronic kidney disease, smoking, and disorders of iron metabolism. Smokers are particularly at risk of vitamin C deficiency because smoking can decrease the absorption of vitamin C in the body. It is therefore important to consume enough vitamin C to maintain good health.

    Food sources of vitamin C

    Vitamin C is found naturally in many foods, primarily fresh fruits and vegetables. Here are some examples of food sources of vitamin C:

  • Citrus fruits (oranges, lemons, grapefruit)
  • Berries (strawberries, raspberries, blueberries)
  • Kiwi
  • Papaya
  • Mango
  • Pineapple
  • Melon
  • Peppers (red, green, yellow)
  • Broccoli
  • Brussels sprouts
  • Cauliflower
  • Spinach
  • Tomatoes
  • It is important to note that vitamin C is sensitive to heat and light, so prolonged cooking and exposure to light can reduce the vitamin C content of foods. It is therefore recommended to eat foods rich in vitamin C raw or lightly cooked to preserve their content.

    How to take your vitamin C?

    When supplementing with vitamin C, it is important to take into account the effects it can have on your body. In some people, vitamin C can produce a booster effect, similar to caffeine. In this case, it is recommended to take it in the morning and/or before training to benefit from its energizing benefits. On the other hand, in other individuals, vitamin C can cause slight drowsiness. In this case, it is better to avoid it during the day and instead take it in the evening. However, vitamin C has diuretic effects, which can disrupt sleep by causing frequent urges to urinate at night.

    To avoid forgetting to take your vitamin C supplement, it is preferable to split the intake without making the protocol too restrictive. You can take your supplement with your meals, or before a workout with proteins or BCAAs to enhance its energizing effects.
