Vitamin C (Ascorbic Acid) pH 5.0-5.5

• Essential Vitamin for human life
• 90 mg is the daily recommended dosage
• Water soluble Vitamin that the body cannot produce, or store, therefore require daily intake
• Inadequate Vitamin C ingestion results in Vitamin C deficiency (scurvy)
• Inadequate Vitamin C ingestion is implicated in Progressive Cognitive Decline/Alzheimer's disease (references next page)
• Vitamin C is absorbed in the terminal ileum (small intestines) by active facilitated transport absorption
• Excess Vitamin C not absorbed by active facilitated absorption is absorbed by gradient diffusion
• Excess Vitamin C  not absorbed by the distal ileum is advanced to the proximal colon (large intestines) by normal peristalsis to ACIDIFY the colon contents
• Colon ACIDIFICATION by excess Vitamin C reduces colon pH, and neurotoxic ammonia absorption from the colon
