• 1000 IU of vitamin D per capsule allows for easy daily dosing
• Easy-to-swallow, highly bioavailable capsule
• In an organic flaxseed oil base for better intestinal absorption

Vitamin D is a hormone now widely recognized as important for many bodily systems and a large number of physiological processes. It may also be one of the most common nutritional deficiencies worldwide. Many recent studies have linked lower levels to an increased risk of cardiovascular diseases, including hypertension, peripheral vascular disease, coronary artery disease, and heart failure, as well as several types of cancer, autoimmune diseases, and type 2 diabetes. Vitamin D is necessary for intestinal calcium absorption, the integrity of skeletal bones, as well as the strength and function of skeletal muscles, and has been associated with overall physical fitness. Vitamin D is essential for the proper functioning of the immune system and can reduce the risk of infection, particularly respiratory tract infections. Given that virtually all body tissues possess a receptor for vitamin D, its importance is difficult to overestimate. Many practitioners recommend supplementation to achieve 25-OH-vitamin D blood levels between 50 and 80 nmol/L, which often requires doses of 1000 to 2000 IU per day, and more for individuals with common genetic variants affecting vitamin D metabolism.
