Our nervous system is responsible for sending messages throughout our body, which effects how our physical and mental processes work. Vitamin C is vital in the role and management of the nervous system and there are higher concentrations of Vitamin C found within the nervous system than in our blood.

  • Stress response

The stress hormone cortisol is released during times of stress, which causes a rise in blood pressure and anxiety. Vitamin C has been researched to reduce levels of cortisol by helping its secretion from the body, therefore also reducing blood pressure and anxiety [1].

  • Adrenal Glands

The adrenal glands use high amounts of Vitamin C during stress because they are essential in the adrenal hormone cascade, and the manufacture of some adrenal hormones. The antioxidant action of Vitamin C also supports the health of the adrenal glands [2,3].

  • Mood

Vitamin C has been researched to have anti-depressant and anti-anxiety effects by modulating neurotransmitters such as dopamine and serotonin, whilst also improving recovery from mental stress and anxiety [3].

  • Antioxidant

The central nervous system and adrenal glands are sensitive to oxidative damage, and has been linked to mental health conditions such as anxiety, depression and stress. Vitamin C is a powerful antioxidant that helps to reduce the oxidative damage [3].
