    *At low doses, oral vitamin C is well absorbed, however the degree of absorption decreases as the dose increases. Research shows that while approximately 72% of a 200mg dose of vitamin C is absorbed, less than 50% of a 1250mg dose is absorbed, and the rest is excreted in urine. Despite popular use of supplemental doses of 1000mg vitamin C, higher doses may actually result in a decreased degree of absorption compared to five divided doses of 200mg.
