what is the difference between vit d2 and vit d 3?
30219
The two forms of vitamin D differ depending on their food sources. Vitamin D3 is only found in animal-sourced foods, whereas D2 mainly comes from plant sources and fortified foods. Since vitamin D2 is cheaper to produce, it's the most common form in fortified foods.

Considerations for vegans Vitamin D2 is always suitable for vegans, but vitamin D3 can be derived from an animal source (such as sheep's wool) or lichen (a vegan-friendly source).

Vitamin D2 is synthetically made from radiating a compound (ergosterol) from the mold ergot. Vitamin D3 is made commercially and synthetically in a similar way that it is produced intrinsically in human and animal skin when exposed to UVB light.

Abstract. Vitamin D is a hormone, not a vitamin. The skin is responsible for producing vitamin D. During exposure to sunlight, ultraviolet radiation penetrates into the epidermis and photolyzes provitamin D3 to previtamin D3.

Vitamin D is added to all of them. The amount of fat is the only difference between them, and it's a big difference. Half the calories in whole milk come from fat and one-third of the calories in 2 percent milk come from fat.

Vitamin D3, also known as cholecalciferol is generated in the skin of animals when light energy is absorbed by a precursor molecule 7-dehydrocholesterol. Vitamin D is thus not a true vitamin, because individuals with adequate exposure to sunlight do not require dietary supplementation.

Vitamin D2 50,000 units requires a prescription, however, Vitamin D3 50,000 units does NOT require one. However, although Vitamin D3 50,000 units does not require a prescription, it is still usually purchased from behind the pharmacy counter and may need to be ordered in.

A: Ergocalciferol or vitamin D2 is a form of vitamin D that is available as a prescription strength tablet or injection. Vitamin D2 is used to treat a vitamin D deficiency, low phosphate levels, rickets, osteoporosis, or hypoparathyroidism. A typical prescription dose of vitamin D2 tablets is 50,000 IU weekly.

Vitamin D3 Is More Effective at Improving Vitamin D Status Vitamin D2 and D3 are not equal when it comes to raising your vitamin D status. Both are effectively absorbed into the bloodstream. However, the liver metabolizes them differently.

The recommended form of vitamin D is vitamin D3 or cholecalciferol. This is the natural form of vitamin D that your body makes from sunlight. Supplements are made from the fat of lambs' wool. However, a clinical study reported in 2008 suggested that vitamin D2 works as well as vitamin D3.

The two major forms are vitamin D2 and vitamin D3. Vitamin D2 (ergocalciferol) is largely human-made and added to foods, whereas vitamin D3 (cholecalciferol) is synthesized in the skin of humans from 7-dehydrocholesterol and is also consumed in the diet via the intake of animal-based foods.

Calcitriol (1,25-dihydroxyvitamin D3), the active form of vitamin D, has a half-life of about 15 hours, while calcidiol (25-hydroxyvitamin D3) has a half-life of about 15 days.

Vitamin D2 is ergocalciferol and comes from plant-based sources. Vitamin D3 is cholecalciferol and comes from animal-based sources. Both supplements are processed in the body by the liver to 25-hydroxyvitamin D, though vitamin D3 is thought to provide higher levels of 25D.

Vitamin D is not one chemical but many. The natural type is produced in the skin from a universally present form of cholesterol, 7-dehydrocholesterol. Sunlight is the key: Its ultraviolet B (UVB) energy converts the precursor to vitamin D3.

Given that your body doesn't care whether it's taking more vitamin D2 or less vitamin D3—as long as it's within the recommended dose—either type could be perfectly fine if you're taking it for general health.
