Vitamin D3 · 2500 IU

- Vitamin D3 (cholecalciferol) is probably more effective in restoring blood levels than the D2 form (ergocalciferol).
- Cholecalciferol has also been shown to increase the proportion of the active form of vitamin D compared to ergocalciferol.
- 2,500 IU of vitamin D per capsule allows for easy daily dosing
- Easy to swallow and highly bioavailable capsule
- In an organic flaxseed oil base for better intestinal absorption
Vitamin D is a hormone widely recognized as essential to many body systems and physiological processes. It is also perhaps one of the most common nutritional deficiencies globally, with insufficient or deficient levels found in almost 40% of Canadians. Vitamin D is essential for the proper functioning of the immune system and may reduce the risk and/or severity of infections, particularly those of the respiratory tract, and particularly in individuals prone to infections. Many recent studies have linked lower levels of this vitamin to an increased risk of cardiovascular disease, including hypertension, peripheral vascular disease, and coronary heart disease.
Vitamin D is needed to help absorb dietary calcium, and it is also important for bone health and muscle strength. Vitamin D has been linked to physical fitness and overall performance, with lower levels linked to frailty, particularly in older adults. Supplementation at clinically relevant doses has been associated with a well-established reduction in osteoporotic fractures. Since virtually every tissue in the body has a vitamin D receptor, it is difficult to overestimate its importance. Many practitioners recommend supplementation to achieve blood levels of 50 to 80 nmol/L of 25-OH-vitamin D. This level often requires doses of 1,000 to 2,000 IU per day, and higher for people with common genetic variants affecting vitamin D metabolism.
