Jarrow Formulas Vegan Vitamin D3 1000 IU is a unique supplement in the form of vegan capsules, containing a high dose of vitamin D3 obtained from lichen. This product is a perfect dietary supplement for vegans, allowing them to maintain healthy bones and joints, as well as derive many other health benefits from its supplementation.
Vitamin D3 (cholecalciferol) is a fat-soluble substance. The body is able to synthesize it on its own, but this is only possible when exposed to strong sunlight. For this reason, a large part of the population struggles with its deficiencies all year round or in winter.
In the case of vegans, too low a concentration of vitamin D may also result from diet, because it is mainly acquired from animal source foods. Therefore, many specialists recommend a year-round supplementation of this substance among vegans, especially in elder people or those with significant deficiencies.
Vitamin D is an important element in the regulation of calcium and phosphate metabolism, in this way influencing the state of the skeleton and blood vessels. Thanks to vitamin D3, it is possible to effectively absorb the building element of bones - calcium, thanks to which they maintain proper strength and resistance. In addition, vitamin D stimulates the formation of bone cells and retains calcium in bones, preventing resorption.
Many other health benefits of vitamin D3 supplementation have also been demonstrated. First of all, this substance supports the functioning of the immune system, strengthening the immune response and reducing inflammation. In addition, it has also been shown to have a beneficial effect on cardiovascular disorders such as hypertension. It also prevents calcium retention in blood vessels, preventing dangerous calcifications.
To sum up, Jarrow Formulas Vegan Vitamin D3 1000 IU is an excellent, quickly assimilated supplement supporting bones and joints, immunity, as well as the circulatory system. It does not contain substances of animal origin.
The supplement is recommended for vegans, whose diet may contain insufficient amount of vitamin D3, which may result in deficiency of this substance in the organism.
It is worth consuming the supplement with meals rich in fat to ensure maximum absorption.
To support the bone and circulatory systems, it is worth combining the preparation with menaquinone-7 (vitamin K2-MK7).

Vitamin D belongs to fat soluble vitamins, occurs in three forms: calciferol (vitamin D1) ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3), it is formed under the action of sunlight for at least 15 minutes per day. In the absence of sunlight it should be administered in the diet in the form of fish oil (Vitamin A + D3) and fish oils. It is responsible for the absorption of calcium and phosphorus. It is the building substance of bone tissue particularly necessary during pregnancy, childhood, and for athletes. It is a component of dietary supplements and nutrients among competetive athletes. Deficiency of vitamin D causes children growth inhibition, and rickets.
For adults - deficiency causes osteomalacia.
Excess of vitamin D causes headaches, alopecia, nausea, drowsiness, blurred vision, pain in the long bones, the deposition of calcium deposits.
Dosage: 400 IU units during the day.
Cholecalciferol, or vitamin D3, is an organic chemical that belongs to the family of D vitamins. It is naturally found in fatty fish, fish oil, egg yolks, milk and dairy products. It is also synthesized in the human body. It is formed from 7-dehydrocholesterol present in the keratinocytes of the spinous and the basal layers of the epidermis, and a pre-requisite for initiating this process is the action of 290-315 nm wavelength UVB radiation on the skin.
Cholecalciferol is a biologically inactive compound. In the body, it undergoes enzymatic hydroxylation – first in the liver, with the participation of 25-hydroxylase, when calcidiol is formed and secondly in the kidneys, where under the influence of 1-α-hydroxylase, calcidiol is converted into the final active form – calcitriol.
The most important role of vitamin D3 in the body is the regulation of calcium-phosphate metabolism, which directly affects normal skeletal mineralization. In addition, it is involved in cell proliferation and differentiation, insulin secretion, as well as in some functions of the nervous, endocrine and immune systems.
Cholecalciferol is the most popular form of vitamin D used in dietary supplements. Studies show that supplementation with vitamin D in this form most effectively and rapidly raises the level of 25 (OH) D3 – a metabolite that is a marker of the level of vitamin D in the body.
Dosage: according to RDI standards for individual age groups.
