Vitamin C Supplements
Vitamin C is a nutrient that the human body cannot produce on its own, so intake relies on a varied diet or supplements. Vitamin C supplements come in several forms:
- Ascorbic acid – The form of vitamin C found naturally in fruits and vegetables. Long‑term use may cause stomach irritation;
- Mineral ascorbates – This form combines ascorbic acid with minerals, making it gentler on the digestive system;
- Liposomal vitamin C – Currently considered the highest quality and most absorbable form, as it penetrates cells easily. Due to its complex production, liposomal vitamin C tends to be more expensive.
Benefits of Vitamin C
Vitamin C is a potent antioxidant that protects body cells from free radicals and slows down aging. Additionally, vitamin C:
- Supports normal immune function;
- Contributes to a healthy energy metabolism;
- Improves iron absorption;
- Aids in collagen production;
- Supports brain and nervous system function;
- Helps reduce fatigue.
Vitamin C is particularly popular during cold and flu season, as a well‑functioning immune system can be preventive. However, studies on this are varied, showing that taking vitamin C during illness may shorten its duration by only a day.
How Much Vitamin C Should You Take?
The recommended daily dose of vitamin C is 80–100 mg for adults. For children, the dose is around 50 mg. Higher doses are suggested for athletes, pregnant and breastfeeding women, individuals with illnesses, or those under stress.
Since vitamin C is water‑soluble, any excess is excreted in urine, making overdose difficult, though not impossible. Overdose levels are around 2–3 g of vitamin C, which can cause digestive issues or increase the risk of kidney stones.
