Description

Vitamin C

Vitamin C is a powerful antioxidant that supports the immune system and helps protect cells from oxidative stress. It is crucial for collagen formation, which is essential for skin elasticity, bone strength, and healthy blood vessels.

Zinc

Zinc is an essential mineral that plays a pivotal role in various bodily functions, including immune response, wound healing, and protein synthesis. It is also integral to cell division and DNA synthesis.

Immune System Support

Together, vitamin C and zinc work to boost the immune system and provide antioxidant protection, helping to combat infections and illnesses such as colds and flu.

Vitamin C is essential for collagen formation and helps reduce tiredness, while zinc plays a crucial role in various bodily functions like immune response, wound healing, and protein synthesis.                                 

Mechanism of Action of Vitamin C and Zinc

Vitamin C
Vitamin C is a powerful antioxidant that helps protect cells from oxidative stress by scavenging free radicals. It also plays a crucial role in:

• Supporting the immune system by stimulating the production and function of white blood cells 
• Enhancing the absorption of non-heme iron, which is important for oxygen transport and energy production 
• Promoting collagen synthesis, which is essential for healthy skin, bones, and blood vessels 

Zinc
Zinc is an essential mineral that is involved in a wide range of physiological processes:

• Supports immune function by promoting the development and activity of immune cells 
• Participates in protein synthesis, cell division, and DNA synthesis, which are crucial for growth and development 
• Acts as an antioxidant, helping to neutralize free radicals and protect cells from oxidative damage 
• Plays a role in wound healing and tissue repair by facilitating the production of new cells
  

  How Vitamin C Supports the Immune System

  Enhances Immune Cell Function

  • Vitamin C helps stimulate the production and function of white blood cells, including lymphocytes (T-cells and B-cells) and phagocytes, which are key players in the immune response.
  • It protects immune cells from damage by neutralizing free radicals and reducing oxidative stress.
  • Vitamin C enhances the ability of neutrophils (a type of white blood cell) to perform their pathogen-killing functions, such as chemotaxis, phagocytosis, and generation of reactive oxygen species.
  • It also promotes the apoptosis (programmed cell death) of spent neutrophils, preventing tissue damage from excessive inflammation.

  Supports Skin Barrier Function

  • Vitamin C is actively transported to the skin, where it acts as an antioxidant and helps strengthen the skin’s defenses against pathogens.

  Shortens Infection Recovery Time

  • Studies show vitamin C supplementation can shorten the duration and severity of respiratory infections, such as the common cold.
  • It may also help reduce recovery time for more serious infections like pneumonia.

  The best natural sources of vitamin C are:

  Fruits

  • Citrus fruits like oranges, grapefruit, lemon, and lime
  • Kiwifruit
  • Strawberries
  • Papaya
  • Guava
  • Cantaloupe
  
  

  Vegetables

  • Red and green peppers
  • Broccoli
  • Brussels sprouts
  • Tomatoes and tomato juice
  • Cauliflower
  • Potatoes
  • Leafy greens like kale and cabbage
  

  Vitamin C

  Water-soluble vitamin important for tissue repair and immune function

  Other Names

  l-ascorbic acid, ascorbic acid, ascorbate

  Sources

  Found in citrus fruits, berries, vegetables, and dietary supplements

  Function

  Involved in tissue repair, collagen formation, enzymatic production of neurotransmitters, immune system function, and acts as an antioxidant

  Ascorbic acid, also known as vitamin C, has the chemical structure C6H8O6. The key features of its structure are:

  • It is a white, crystalline solid that is water-soluble
  • It contains a furan ring with a lactone group
  • It has two chiral centers, making it a stereoisomer
  • It has an enediol group adjacent to the carbonyl, which increases its acidity
  • The deprotonated form is the ascorbate anion, which is resonance-stabilized

  The IUPAC name is (5R)-5-[(1S)-1,2-dihydroxyethyl]-3,4-dihydroxy-2(5H)-furanone. The molecular structure can be represented as:
