Vitamin D3 Dosage Recommendations
Healthy adults need to get enough vitamin D on a regular basis to maintain an adequate blood level of 25-hydroxyvitamin D -- the major circulating form of vitamin D in the body. Most healthy adults can achieve this with a daily supplement providing 1,000 IU/day of vitamin D such as RealDose® Vegan Vitamin D3.
People with low vitamin D stores typically need to supplement for a 2-3 months to replenish low body stores. For these people, it’s important to talk with a physician for individual support and guidance.
You can get too much vitamin D, which can result in potential adverse effects. According to the Institute of Medicine, the highest intake of vitamin D likely to be safe for almost all healthy adults is 4,000 IU/day.
As with all dietary supplements, talk to your doctor before taking Vegan Vitamin D3 or another vitamin D supplement if you have or suspect a medical condition, are taking prescription drugs, or are pregnant or nursing.
