![]() However, more recent studies show that vitamin D3 and vitamin D2 are fairly equal for bone health. Previous research suggested that vitamin D3 was a better choice than vitamin D2. That’s because vitamin D seems to help mitochondria-the part of a cell that generates energy-use oxygen and power various parts of the body, including muscles. Low energy or fatigue is a common symptom of vitamin D deficiency. However, some research has shown that some patients who are vitamin D deficient may need up to 50,000IU weekly to reach normal ranges. Even on the high end, this would only equal about 5,000IU weekly. Is 50 000 units of vitamin D2 a lot?įor the majority of the population, a daily intake of 400-800IU of vitamin D is adequate. In summary, long-term supplementation with vitamin D3 in doses ranging from 5000 to 50,000 IUs/day appears to be safe. Can I take 5000 IU of vitamin D3 everyday?

Is D3 more potent than D2?ĭ3 is approximately 87% more potent in raising and maintaining serum 25(OH)D concentrations and produces 2- to 3-fold greater storage of vitamin D than does equimolar D2. The liver metabolizes vitamin D2 into 25-hydroxyvitamin D2 and vitamin D3 into 25-hydroxyvitamin D3. However, the liver metabolizes them differently. Both are effectively absorbed into the bloodstream. Vitamin D2 and D3 are not equal when it comes to raising your vitamin D status.
