Vitamin D3: Description
Vitamin D is a fat-soluble vitamin essential for the metabolism of calcium that is involved in various cellular functions and helps prevent several illnesses.
Vitamin D plays an essential role in the normal function of the immune system.
Vitamin D deficiency can cause recurrent winter colds, which in turn weaken our defences.
Vitamin D bolsters the body's immunity and helps it fight off colds.
Vitamin D also helps keep our bones healthy, while vitamin D deficiency increases the risk of osteoporosis.
Vitamin D can be synthesised in the skin after exposure to ultraviolet-B radiation or can be obtained through diet, from foods of animal and plant origin.
Our vitamin D3 (cholecalciferol) of plant origin is 100% natural and suitable for vegetarians and vegans. It is the only vitamin D3 registered with the Vegan Society and the Vegetarian Society!
Vitamin D3: Detailed information
What is vitamin D? Properties
Vitamin D is a fat-soluble vitamin that plays an essential role in bone mineralisation by regulating calcium and phosphorus levels.
Its main function is to maintain concentrations of calcium and phosphorus at values that facilitate cellular processes, neuromuscular function and ossification. It is also involved in the renal production of renin, an enzyme involved in regulating blood pressure (1).
Vitamin D improves musculoskeletal health (2) and severe deficiency in this vitamin can cause rickets in children, muscle pain and weakness, and osteomalacia (“soft bones”) due to poor bone mineralisation (1).
Vitamin D and the immune system
Vitamin D plays an important role in the immune system and has been linked to the innate immune response (first line of defence in immune response) of the epithelial cells (cells that play an important role in preventing lung colonisation by infectious agents) (3).
Various studies in adults have also demonstrated a correlation between low levels of vitamin D and a higher incidence of respiratory infection (3-5). A study that evaluated the influence of vitamin D levels on the onset of respiratory infections in athletes training during the winter months concluded that there was a high incidence of symptoms of infection of the upper respiratory tract (sore throat, sneezing, fever etc.) in subjects with lower levels of vitamin D in the blood (5).
How do we get vitamin D?
Vitamin D3 (cholecalciferol) can be synthesised in the skin after exposure to ultraviolet-B (UV-B) radiation, or can be obtained through diet. Fungi and plants synthesise ergosterol and foods of animal origin provide 7-dehydrocholesterol; after receiving ultraviolet light these precursors are transformed into vitamin D2 (ergocalciferol) and vitamin D3 respectively (1). As well as animals, vitamin D3 has also been found to be present in some plants and lichen (6-7).
Our product: Vitamin D3 for vegans
Our vitamin D3 (cholecalciferol) is suitable for vegans since it is not from animal origin, but instead comes from lichen, an organism created through symbiosis between a fungus and algae.
