Vitamin D is best known for its role in aiding the absorption of calcium from the digestive system and promoting bone formation, but it has many other actions including balancing immune function and supporting mood. Vitamin D is synthesized by the skin following exposure to ultraviolet rays from sunlight, but many people do not spend enough time outdoors and become deficient in this essential vitamin. Vitamin D deficiency has been linked to numerous health conditions including osteoporosis, rickets, autoimmune conditions, diabetes, SAD (seasonal affective disorder), chronic pain and frequent infections.
There is an obvious need to supplement with extra vitamin D especially in the elderly and children, during the winter, and for people with chronic diseases. Vitamin D3 is the most effective form of supplemental vitamin D (compared to D2, a less absorbable form). AOR’s Vitamin D3 is naturally and ethically sourced from sheep wool oil collected during shearing. Up to 1000 IU is considered safe for people of all ages from infants to seniors. Talk to your healthcare provider about taking higher doses.
