The animals, with very few exceptions, all produce multi-gram [standardized to 154 pounds] doses of ascorbic acid for themselves every day of their lives. With the possible exception of a strict "garden of Eden" diet, i.e. raw fruits and vegetables [only], I strongly believe we humans must do the same, e.g. typically via ingestion, if we want continuous optimal health, i.e. I recommend, Joe, that you ingest [as I do, and have, for the past 20 years] a Bowel Tolerance dose of ascorbic acid every day [again, for optimal health].
I hope that answers your question, Joe. If not, please repost.
