What dosage is considered "mega dosing" for vitamin c? i try not to take too much, currently at 1000 mg per day.

Per consumerlab.com:: ...your intake is pretty high, & the recommended daily intake of vitamin C for adults is only 75 mg to 120 mg, with an additional 35 mg for smokers. Very high doses of vitamin C are known to cause gastric discomfort, diarrhea, may actually increase risk of cataracts, reduce effectiveness of some drugs, risk liver damage (with Tylenol), risk some kidney stones, interfere with many lab tests.
