D3 VS D2

Vitamin D supplements maybe in the form of D2 (ergocalciferol) or D3 (cholecalciferol).

Unived’s D-veg is made using 2500 I.U. of vegan vitamin D3, which readily binds with vitamin D receptor and effectively maximizes calcium absorption. Among the two chemically distinct forms of vitamin D, vitamin D3 is proven to be more potent as compared with vitamin D2.[1]

  • A study found the potency of vitamin D2 to be less than one-third that of vitamin D3.[2]
  • Vitamin D2 has less affinity for VDR (vitamin D receptor), which are present in most major organs and muscles. Further, it has a shorter half-life than vitamin D3.[1] This means that, vitamin D3 stays in your body for a longer time whereas vitamin D2 is eliminated out of your body much sooner.
  • D3 is approx. 87 percent more potent in raising and maintaining vitamin D concentrations and produces 2 to 3-fold greater storage of vitamin D than D2.[3]

What is Vitamin D

Vitamin D is a fat-soluble substance necessary for the smooth working of several of the body’s physiological functions. Though it is most popularly known for its important role in bone heath, research has now revealed its relevance in overall health, prevention and cure of various ailments.

“Vitamin D is, without question, the miracle nutrient of the century.” Mike Adams, natural health researcher and author.


Vitamin D has a unique functioning system as compared to other vitamins. In fact, it functions more like a hormone, impacting metabolic pathways, cellular functions, and the expression of myriad genes.[5]

The main function of vitamin D is to regulate the absorption of calcium and phosphorus in our bones and aid in inter-cellular communication throughout the body.[6] It also positively influences[7]:

  • Immune system, helping you to fight infection
  • Muscle function
  • Cardiovascular function, for a healthy heart and circulation
  • Respiratory system – for healthy lungs and airways
  • Weight loss
  • Brain development
  • Anti-cancer therapy

Without adequate levels of vitamin D you are likely increasing your risk of diseases ranging from heart disease and Alzheimer’s to weak bones and diabetes.[8]

Vitamin D3

‘Vitamin D3 is essential for life in higher animals.’ Anthony Norman[9] D3 is the most natural form synthesized by human beings, when the sun’s UVB light strikes their skin.[10] The synthesis takes places photochemically with the help of provitamin D, 7-dehydrocholesterol, present in the epidermis or skin. A complex series of transformations of the provitamin result in the generation of Vitamin D3.[9]

The molecular structure of vitamin D3 has a close semblance to that of steroid hormones[9] – such as estradiol, cortisol, and aldosterone – and it is referred to by researchers as a secosteroid hormone.[5] It is one of the foremost regulating factors for calcium homeostasis.[9]

In order to function within your body vitamin D3 is reduced to its metabolites including 1α, 25-dihydroxyvitamin D3 (or 1,25-vitamin D3 for brevity).

The steroid hormone functions in sync with the vitamin D Receptors (VDR) found in almost every tissue type and cells in your body[10] to bring out the optimum impact of vitamin D on your bodily functioning.[9]

D2 and D3

Researchers reveal vitamin D3 or cholecalciferol to be substantially more effective than vitamin D2 or ergocalciferol. The test of potency is determined on the basis of their ability to improve the serum 25(OH) D concentrations – that determine the nutritional levels of vitamin D in your body.[11]

  • A study found the potency of vitamin D2 to be less than one-third that of vitamin D3.[2]
  • Vitamin D2 has less affinity for VDR (vitamin D receptor) and shorter shelf life than vitamin D3.[1]

Unived’s D-veg is made using 2500 I.U. of vitamin D3 with organic spirulina, which readily binds with vitamin D receptors and effectively maximises calcium absorption.

The Sunshine Vitamin

Sunshine vitamin is a popular connotation for vitamin D and is commonly believed to be available to everyone in abundance through sunlight. Yet, vitamin D deficiency (VDD) is among the most common medical conditions in the world.[5] In fact vitamin D deficiency is turning into a global epidemic with an estimated one billion people bearing insufficient levels.[12]

Reduced sunlight exposure due to factors such as clothing, sunscreens and glass shielding notably reduce if not completely stop the production of vitamin D3 in the skin.[13] The amount of vitamin D you get from exposing your bare skin to the sun depends on[14]:

  • The time of day. Exposing your skin during the middle of the day produces more Vitamin D.
  • Your location. If you live closer to the equator, it is easier to produce vitamin D throughout the year.
  • Your skin color. People with darker skin make lesser vitamin D as compared with pale skinned individuals. Darker skin possesses natural sun protection (melanin) and requires at least three to five times longer exposure to make the same amount of vitamin D as compared to a white skin tone.[15]
  • The more skin you expose the more vitamin D your body will produce.
  • Change in latitude, season or time of day impacts the skin’s vitamin D production.[16]
  • Season dramatically influences the cutaneous production of vitamin D3.[17] Very little vitamin D is produced in the skin during winter.[17]
  • Low vitamin D status, as is it largely understood, may occur despite “more than adequate” sun exposure.[18]

Another factor that hampers the production of vitamin D is the numerous measures people take, to protect the skin from the sun as sun exposure is purported to have harmful effects on your skin. Few people know that a sunscreen (SPF 8) lowers the skin’s capacity to produce vitamin D3 by more than 95%.[17]


There is very little awareness about the importance of vitamin D and what they can do to avoid the numerous deficiency associated disorders, including heart disease, cancer, and osteoporosis.

However, the largely unattended nutritious necessity of this vitamin is now coming to the fore since an increasing research reveals a paucity of this nutrient among a large population.[19]
