Vitamin D, Cholecalciferol, Ergocalciferol, Vitamin D

Vitamin D is consumed in the form of vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). It can be obtained exogenously (via food) or by endogenous synthesis from cholesterol, which is initiated by sun’s UVB rays incidence on the skin. The main function of vitamin D is to maintain calcium homeostasis. Its deficiency can be observed in individuals who have low sun exposure, lipid absorption problems or dietary problems.

What are Vitamin D benefits?

Vitamin D is one of the 24 micronutrients essential for the survival of the human organism, being a fat-soluble element that our skin synthesizes after being exposed to the sun. For this reason, vitamin D is also often called the ‘sunshine vitamin’. Although the sun is the main natural source of the nutrient, vitamin D can also be found in fish and eggs. It is also worth noting that according to studies, vitamin D is associated with a wide range of benefits such as improved immune health, bone health and well-being, improved growth and muscle development, increased cognition, reduced risk of cancer, heart disease, diabetes, and multiple sclerosis, and reduced osteoporosis, falls, and fractures.

Bone and Joint Health Vitamin D and Bone and Joint Health

Bone and joint health are deeply affected by vitamins, hormones and minerals, such as calcium, vitamin D and thyroid hormones. Supplements that affect bone and joint health help their structure and strength, in addition to contributing to the healthy balance of involved nutraceuticals.
  • Bone Density

    Bone density or bone mineral density (BMD) is the amount of bone mineral in bone tissue. The measurement of bone mineral density is used in medicine as an indirect indicator of osteoporosis and risk of fractures.

Immunity Vitamin D and Immunity

The immune system is made up of cells, tissues and organs that act in the organism's defense against the harmful effects of external microorganisms. The supplements indicated for immunity act as strengthening agents of this system, increasing the antibodies production and, consequently, its defense activity.
  • Preventive Immunity

    White blood cells - or leukocytes - are the body's defense cells that destroy foreign agents, for example, bacteria, viruses and toxic substances that attack our body and cause infections or other diseases. There are also enzymes that refer to the antioxidant defense system that plays the role of inhibiting and/or reducing the damage caused by the harmful action of free radicals or non-radical reactive species.
