Is vitamin D3 really a hormone?

Vitamin D is actually a hormone rather than a vitamin; it is required to absorb calcium from the gut into the bloodstream. Vitamin D is mostly produced in the skin in response to sunlight and is also absorbed from food eaten (about 10% of vitamin D is absorbed this way) as part of a healthy balanced diet.

What is vitamin D3 good for in the body?

Vitamin D (ergocalciferol-D2, cholecalciferol-D3, alfacalcidol) is a fat-soluble vitamin that helps your body absorb calcium and phosphorus. Having the right amount of vitamin D, calcium, and phosphorus is important for building and keeping strong bones.

What is D3 serum used for?

Vitamin D3, also known as cholecalciferol, is a supplement that helps your body absorb calcium. It's typically used to treat people who have a vitamin D deficiency or related disorder, such as rickets or osteomalacia.


Support Bone and Heart Health With Plant-Based Vitamins

Welcome to our pure, plant-source product, Premier Vitamin D3+K2. This formula has been designed to feature plant-source vitamin D3 in addition to plant-source vitamin K2 in vegetable capsules -- without undesirable chemical tagalongs.

Vitamins D and K work together to promote proper calcium metabolism, free-flowing blood circulation, bone formation and bone strength. Vitamin K promotes the proper metabolism of calcium to the bone from the circulatory system while vitamin D supports proper bone health. A typical recommended daily dose for these vitamins is 5,000 IU of D3 with 180 mcg. of K2 as MK-7.


At a hefty 5,000 IU of D3 and 180 mcg. of K2 per capsule, Premier Vitamin D3+K2 contains an exclusive 100% vegan/ vegetarian friendly formula with both vitamin D3 and K2 present in clinically established dosages that promote cardiovascular and bone health. This supplement is the perfect choice for those who wish to significantly increase their vitamin D3 and vitamin K2 intake without consuming animal by products.

New studies regarding bone and cardiovascular health are providing insights into a type of synergistic interplay between D and vitamin K (which has been known to support the proper blood-clotting mechanisms of the cardiovascular system). Scientists have presented powerful evidence revealing that optimal concentrations of each vitamin are beneficial for bone and heart health. Vitamin D promotes vitamin K-dependent proteins that require the presence of vitamin K to function properly.


Plant-Source Vitamin D3 (Vegan/Vegetarian Friendly)

Taking vitamin D in higher doses than previously (such as a robust 5,000-10,000 IU/day) has become popular over the last few years. This trend is based on findings that suggest that this daily amount is required to achieve optimal blood levels of vitamin D (ideally, over 80 ng/mL of 25-hydroxyvitamin D).

The body requires sufficient amounts of vitamin D in order to absorb calcium. The importance of adequate vitamin D levels for skeletal health and bone density has been well established. Although bone density is often associated with calcium intake, insufficient vitamin D levels directly affect calcium absorption and is an important consideration for bone health. Without adequate absorption of vitamin D, the body must steal calcium from its stores in the bones, which compromises bone structure. Clinical research suggests that taking vitamin D can support healthy bone structure.
