How Vitamin D Works
Vitamin D regulates how much calcium and phosphorus you absorb from food. It is also essential for proper hormone function.
Calcium is one of the essential nutrients for bone health. Phosphate is also necessary for healthy bones, teeth, muscles, and nerves.
There are two types of vitamin D: vitamin ‘D2,’ which can be found frequently added to plant-based foods as a synthetic form, and vitamin D3, which is the same form synthesized in your skin when it’s naturally exposed to sunlight.
Vitamin D3 can also be derived from real animal sources in supplements (like lamb’s wool) or plant sources (lichen or algae). Most D3 is derived from lanolin – sheep’s wool, so if you are looking for a vegan d3, pay special attention to the ingredients.
Consuming vitamin D3 supplements will ensure that your body has enough vitamin D to maintain proper function, especially during the winter months.
If you're low on vitamin D, your body won't get enough calcium from food, nor will it be effectively utilized by the body.
For optimal bone health, getting more D3 through supplementation is vital. This will improve your peak bone density which, in turn, protects you against fractures, arthritis, joint pain, and osteoporosis.
A deficiency of vitamin D appears to increase the chance and risk of heart disease, stroke, and high blood pressure. Vitamin D3 has the potential to maintain healthy heart function and lower the risk for metabolic disorders like diabetes and heart disease in conjunction with a healthy diet.
Anti-inflammatory and Immune System Effects
Vitamin D deficiency can increase your risk of developing allergies, asthma, and other skin conditions, and a deficiency appears to worsen already present allergy symptoms.
There is a massive amount of research showing Vitamin D’s benefit on the immune system – and as protective against viral and pathogenic infection.
During pregnancy, taking vitamin D supplements can appear to have a large impact on the chance of babies developing asthma. Of course, pregnant women should always consult their doctor before taking any supplements.
