It goes straight into your bloodstream, allowing blood levels that oral doses simply can't reach. ## Side-by-Side Comparison | | **IV Vitamin C** | **Oral Vitamin C** | | --- | --- | --- | | **Absorption** | Directly into bloodstream | Limited by the gut | | **Peak blood levels** | Much higher | Capped | | **Digestive side effects** | Avoided | Possible at high doses | | **Convenience** | Clinic visit | Anywhere | | **Screening needed** | G6PD test for high doses | Not usually | | **Best for** | High-dose boost | Daily maintenance | ## What About Liposomal Vitamin C?
