Frequently Asked Questions

  • For maintenance, 500-1000mg daily is sufficient. For immune support during illness, 2000-4000mg in divided doses. The body can only absorb ~200-500mg at once, so split large doses throughout the day. Liposomal forms bypass this limit with 2-3x better absorption.

  • For most people, standard ascorbic acid at 500-1000mg is sufficient. Liposomal vitamin C is worth the premium if you need higher therapeutic doses (2000mg+) without GI distress, or if you have absorption issues. Studies show liposomal C achieves 2-3x higher blood levels than standard forms.

  • Vitamin C is water-soluble and excess is excreted in urine. The main risk of high doses (3000mg+) is GI distress (diarrhea, cramping) and increased oxalate production, which may contribute to kidney stones in susceptible individuals. The 'bowel tolerance' test — increasing dose until loose stools, then backing off — is a common practitioner approach.

  • Meta-analyses show regular vitamin C supplementation reduces cold duration by 8% in adults and 14% in children, and reduces severity. It does NOT prevent colds in most people, but it does in those under physical stress (athletes, military). Taking vitamin C after cold symptoms start has minimal benefit — daily prevention is key.

  • Take with food to reduce potential stomach acidity. Morning dosing is common since vitamin C may mildly increase alertness. If taking large doses (1000mg+), split into 2-3 doses throughout the day for better absorption and sustained blood levels.
