ICD-10 code: E55.9, known as “vitamin D deficiency,” refers to a lack of vitamin d in your body. This is the primary cause of reducing functions and performance of your muscles and bones that can cause major issues which are gradually increased over time. This vitamin helps you absorb calcium, phosphate, and magnesium, which helps your body run vital functions, including an increase in bone immunity and the nervous system.
Vitamin D deficiency leads to osteomalacia and rickets in children and osteomalacia in adults. The best source of vitamin D is sunlight, but too much of it can cause skin aging, skin damage, and also skin cancer due to overexposure to UV rays.

What Are The Major Types Of Vitamin D?
When taking Vitamin D it is always better to opt for oil-based supplements or take it with food that contains fats, due to its fat-soluble properties. The Vitamin D is classified into two main categories which are Ergocalciferol known as Vitamin D2 and Cholecalciferol known as Vitamin D3
Vitamin D2 (Ergocalciferol)
Vitamin D is a vegetarian-based vitamin that is extracted from plants. This kind of vitamin is widely produced as it is much cheaper in terms of cultivating, processing, and production. The major source of vitamin D2 includes fortified foods such as cereals, plant-based milk, infant formula, margarine, orange juice, yeasts, and some species of mushrooms. It is also available in the form of supplements most often in the form of oil-based capsules.
Vitamin D3 (Cholecalciferol)
Vitamin D3 comes from animal and fish sources and can be found commonly in many foods, although it can also be made through lichen which is a symbiotic partnership of two separate organisms which are fungus and an alga commonly found on trees, soil, rocks, cars, old farm equipment, houses, tombstones and more. Vitamin D3 is commonly found in the following foods:
- major fish species
- Cod liver oil
- Dairy products
Difference Between Vitamin D and D3 And Which Is Better?
There are only two sources of vitamin D which are Vitamin D2 and D3. Both D2 and D3 are the subclass of vitamin D and have significant differences in the terms of effects. There is an ongoing debate between biological scientific researchers about D2 and D3 effectiveness in blood levels.
Vitamin D2 ergocalciferol is a plant-extracted vitamin that is not easily absorbed in the blood as compared to Vitamin D3 in the body. According to the Harvard Research Center, a group of randomized controlled trials for meta-analysis was compared to the effectiveness of D2 and D3 found that D3 has more tendency to raise blood concentration and can sustain its level for a longer period as compared to D2. Some researchers preferred Vitamin D3 over D2 as it is produced naturally in the body and also found in some food that contains Cholecalciferol which is easily converted to 1,25-dihydroxyvitamin D as it is an active form of vitamin D.
