Vitamin C Normal Level
Normal levels of vitamin C in blood are in the range of 0.4 to 2.0 mg/dL in healthy adults. The actual level at which we can announce that vitamin C is in excessive amount is not clear yet. Vitamin C levels below 0.2 mg/ or less than 0.4 mg/dL are persistent with a potential risk of deficiency because of inadequate stores of vitamin C in body tissues. In addition, vitamin C values above 3.0 mg/dL are indicator of toxic intake. Whether vitamin C in excess is for sure toxic and continues to be certain. After consumption of vitamin C, there is a rapid increase in plasma values within 1 to 2 hours.
However, limited studies recommend that toxic amounts of vitamin C might induce uricosuria and in people with glucose-6-phosphate dehydrogenase insufficiency might also induce elevated red blood cell weakness. Testing of patients with non-fasting blood specimens or the consumption of vitamin supplementation can lead to increased vitamin plasma concentrations. The reference values are a set of values for people who are fasting and does not apply on people who are eating or taking vitamin C supplements. The plasma vitamin C concentrations might reach the peak concentration between 3 to 6 hours after ingestion.
