Vitamin C | L-ascorbic acid

Supports overall vitality: The beneficial effects of ascorbic acid extent throughout the body. One of the most important functions of this vitamin is its role as a cofactor in collagen production. This is important for skin, as it can be more flexible, have less wrinkles and maintain a youthful appearance, but not only that. Collagen is a very important building block of cartilage, and its proper level is essential for the smooth functioning of joints. It also helps to maintain the elasticity of blood vessels. It has been proven that vitamin C can counteract hardening of the arteries (arteriosclerosis) and even reverse changes that have occurred in its early stages. Besides that, it may support maintaining proper blood pressure, since it helps to relax blood vessels. It is no less important that this substance increases mineral density of the bones and strengthens them by boosting collagen synthesis. Supplementation with ascorbic acid can be helpful for people who want to maintain a healthy weight. Studies suggest that people with a proper vitamin C level are able to lose 30% more fat during workout than those with deficiencies.

Supports the immune system: Vitamin C exhibits immunomodulating properties. It has been proven to stimulate the production of interferons, which trigger defense mechanisms of the body to fight harmful microbes. It activates NK cells that are responsible for destroying abnormal cells, potentially counteracting tumor development. This vitamin improves the functioning of T lymphocytes (which inactivate pathogens and control the response of the entire immune system) and B lymphocytes (which produce antibodies – vitamin C is also involved in this process). It has a beneficial influence on the other immune cells as well: granulocytes (able to destroy bacteria and parasites), monocytes and macrophages (which devour pathogens and abnormal cells of the body). Besides stimulating natural defense mechanisms of the body, it can also slow down the proliferation of viruses, making it easier for the immune system to fight them. Additionally, it inhibits the action of pro-inflammatory cytokines, preventing the excessive spread of inflammation.

Improves nervous system function: Of all the internal organs, the brain is the one that contains the highest amounts of vitamin C. This can be an indicator of how important ascorbic acid is for the proper functioning of the nervous system. The compound is essential for many processes, including the production of norepinephrine and the release of acetylcholine into the synapse. It also stimulates the expression of BDNF, a compound necessary for neurogenesis, and participates in the induction of LTP (long-term potentiation, the basic mechanism of neuroplasticity). Therefore, it takes part in the transmission of signals in memory and learning processes. In addition to that, it helps to take care of the condition of the nervous system. It strengthens the walls of the blood vessels, supports the formation of myelin sheaths and prevents damage to neurons due to glutamate overexcitation, which can be toxic. Research indicates that intake of vitamin C can positively influence cognitive function, but also improve mood and reduce perceived fatigue.

Neutralization of free radicals: Ascorbic acid is one of the best known and most potent antioxidants. As such, it contributes to better health and improved functioning of the entire body. During a study involving cigarette smokers (in whom lipid peroxidation rates are usually elevated), it was proven that vitamin C supplementation significantly reduced lipid peroxidation, thus counteracting the impairment of the structure and activity of biological membranes – the processes related to the development of atherosclerosis. The antioxidant properties of this vitamin also contribute to supporting the condition of blood vessels and the heart, but also enhance the prevention of brain disorders. Ascorbic acid can protect the body from free radicals formed under the influence of heavy metals, e.g. lead.
