Difference Between Vitamin D2 and Vitamin D3

Vitamin D2 and Vitamin D3 both forms can both treat and prevent vitamin D deficiencies. D3 has proven more efficient at doing this due to better absorption by the body, systemization through sunlight exposure, etc.

Vitamin D is an essential fat-soluble nutrient necessary for Maintaining strong teeth, Bones, and Muscles. Vitamin D can only be manufactured by our bodies when exposed to sunlight, UVB rays activate skin cells to produce Vitamin D3. Dietary sources also offer natural sources, including salmon, mackerel, and tuna as well as fortified cereals milk, and orange juice containing added Vitamin D3.

Vitamin D converts into an active form called calcitriol once inside of our bodies, where it regulates calcium and phosphorus absorption through our digestive systems this promotes bone health while helping prevent osteoporosis.

What is Vitamin D2?

Vitamin D2, also Referred to as Ergocalciferol, is produced naturally by Plants. You can find it in certain mushrooms and fungi It’s often fortified into food products and supplements.

Vitamin D2 has a lower potency compared to Vitamin D3, Meaning higher doses will need to be consumed to reach Similar levels in the circulation in your body. Its stability may also decrease significantly with exposure to heat, oxygen or light making its usage unadvisable and potentially hazardous for health purposes.

Vitamin D2 in our bodies is converted to its active form (calcitriol) through chemical processes occurring in both kidneys and liver, inducing various chemical reactions that regulate calcium-phosphorus balance within our intestinal system as well as promote bone mineralization.

Studies indicate that Vitamin D2 may not be as effective at treating and preventing vitamin D deficiency as its more potency cousin, Vitamin D3. According to these research findings, supplementing with more Vitamin D3 could raise levels and support bone health more efficiently supplementation is therefore often recommended.

What is Vitamin D3?

Vitamin D3, also Referred to as Cholecalciferol, is produced naturally through exposure to UVB radiation on skin surfaces and then stored. Dietary sources including egg yolks and fatty fish can provide sources of Vitamin D3, with added supplements being another common source.

Vitamin D3 is considered the biologically most active form of Vitamin D. It’s more effective at raising levels in the blood and supporting bone strength, plus more stable than its predecessor (Vitamin D2) due to heat, oxygen, or light degradation.

Vitamin D3 in our bodies is converted to its active form (calcitriol) through chemical processes occurring in both kidneys and liver, thus helping regulate calcium and phosphorus intake into our intestinal tract and promoting bone mineralization.

Key Difference Between Vitamin D2 and Vitamin D3

Here’s a comparison chart of Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol):

• Cheese: Different types of cheese, including Swiss as well as cheddar, have very little Vitamin D3.
• Mushrooms: Most mushrooms have Vitamin D2, but certain varieties, such as shiitakes can naturally produce tiny amounts of vitamin D3 in response UV or sunlight in the course of growth.

Vitamin D2 vs. D3: Which Is better?

• Vitamins D2 and D3 both serve Similar roles within the body, including treating or preventing vitamin D deficiency. Of the two vitamin options, Vitamin D3 proves more successful at raising Vitamin D levels and improving bone health than its predecessor Ergocalciferol.
• Vitamin D3 is more readily absorbed and utilized by the body than Vitamin D2, making it easier for it to reach desired blood levels of Vitamin D circulating than higher dosages of D2. Plus, its potency means lower doses are necessary to attain similar effects as higher dosages.
• Vitamin D3 is produced naturally through sun exposure. Studies suggest this form is more efficient at increasing levels and improving bone health than taking vitamin D2 through food sources.
• Vitamin D3 may help individuals suffering from osteoporosis or at risk of vitamin D deficiencies to supplement their intake and keep levels optimal.

Summary

Vitamin D is an indispensable nutrient, playing an integral part in bone and immune health. Vitamin D2 and Vitamin D3. Both forms can treat and prevent vitamin D deficiencies D3 has proven more efficient at doing this due to better absorption by the body, systemization through sunlight exposure, etc.

When supplementing, consult with a healthcare provider as to their daily recommendation either form can be supplemented.
