What is Vitamin C?

Vitamin C refers to the vitamin activity humans need for normal function. In supplements, that activity is commonly provided by L-ascorbic acid, sodium ascorbate, calcium ascorbate, or other ascorbate forms.

Whole foods are different from isolated ingredients because they provide vitamin C together with naturally occurring plant compounds such as bioflavonoids. Vitamin C plays a role in normal immune function, antioxidant protection, collagen formation, and helping the body absorb non-haem iron from plant foods.

How does Vitamin C work?

Vitamin C donates electrons, which is one reason it acts as an antioxidant. It also helps enzymes that build collagen, the structural protein used in skin, blood vessels, gums, and connective tissue.

Because humans cannot make vitamin C, low intake can become relevant when diets are poor in fresh fruit and vegetables.

Why people use it

People usually look for vitamin C when they want immune, antioxidant, or collagen support.

It is especially relevant when diets are low in fresh produce or when someone wants a consistent daily vitamin C intake.

What does liposomal delivery add?

Liposomal delivery uses phospholipid carriers to help protect selected nutrients in a liquid formula.

For Vitamin C, the delivery format is mainly about absorption, stability, and making the serving practical to take.

Food sources or natural sources

Vitamin C is found in citrus fruit, berries, guava, kiwi, peppers, broccoli, and leafy greens.

Interesting fact

Humans are one of the few mammals that cannot make their own vitamin C, which is why we need to get it from food or supplements.

Safety notes

High intakes may not suit everyone and can cause digestive discomfort in some people. People with kidney-stone concerns should ask a healthcare professional before using high-dose vitamin C.

Simple takeaway

  • Vitamin C must come from food or supplements.
  • It supports immune function, antioxidant protection, and collagen formation.
  • Fruit and vegetables are important daily sources.
