What is Vitamin C?

Vitamin C is an essential nutrient that supports overall health, especially as we age. It acts as a powerful antioxidant, protecting cells, supporting immunity, and maintaining healthy skin. Since our bodies can’t produce or store vitamin C, we need to get it consistently from vitamin C fruits and foods or supplements.

Vitamin C Benefits

Antioxidant Protection
Vitamin C is a strong antioxidant that helps fight free radicals. These free radicals can cause oxidative stress, leading to premature aging and various health problems. By neutralizing these harmful molecules, vitamin C helps protect your cells and DNA from damage. This protection supports overall wellness and may lower the risk of chronic diseases linked to oxidative stress.
Immune Support
Known for supporting immune function, vitamin C maintains the body's ability to fight infections and recover faster from illnesses. Regular intake supports daily immune health. It optimizes the production and function of white blood cells, which are essential for defending your body against germs.
Skin Health
Vitamin C is essential for collagen production, a protein that keeps skin firm and resilient. This promotes skin elasticity, reduces wrinkles, and helps wounds heal efficiently.
Joint and Tissue Support
Vitamin C contributes to the maintenance of connective tissues, bones, and joints, especially important for aging adults. Regular intake can help with mobility and reduce stiffness.
Heart Health
Research suggests that vitamin C may promote cardiovascular health by supporting healthy blood pressure levels, optimizing blood vessel function, and potentially lowering the risk of heart issues.
Eye Health
Some studies suggest that vitamin C may support eye health by helping to slow the progression of age-related macular issues, though further research is needed. Vitamin C may also support the health of blood vessels in your eyes, promoting overall vision.

Specific Group

Interaction with Other Ingredients

Vitamin C is a powerful antioxidant that helps your body absorb iron more effectively. When taken together, Vitamin C changes plant-based iron into a form that the body absorbs more easily. This combination can be especially helpful for supporting iron levels, as it boosts the absorption of non-heme iron, found in foods like vegetables, legumes, and grains.

Adding Vitamin C-rich foods - such as oranges, bell peppers, or strawberries - to meals with iron can maximize your body’s ability to use this essential mineral. This support for iron absorption can help maintain energy and overall health.

Vitamin C Food Sources

Vitamin C is naturally found in various fruits and vegetables, providing essential support for overall health. Some of the best sources of vitamin C include:

  • Citrus Fruits (Oranges, lemons, grapefruits, and limes)
  • Berries (Strawberries, raspberries, and blackberries)
  • Vegetables (Bell peppers, broccoli, and leafy greens)

If you aren’t getting enough from food alone, supplements like vitamin C tablets, vitamin C powder, and vitamin C capsules can help ensure your body has what it needs each day.

Vitamin C Side Effects

Vitamin C is generally considered safe when taken in recommended amounts from food or supplements. However, consuming high doses of Vitamin C supplements may lead to side effects in some individuals. These side effects can include digestive issues like stomach cramps, nausea, and diarrhea.

In some cases, excessive intake of Vitamin C might increase the risk of kidney stones, especially for those with existing kidney conditions. High doses can also interfere with certain medical tests, potentially affecting the results.
