I encourage you to peruse at least the first ten paragraphs of Dr. Cathcart's article. There you will see that your Bowel Tolerance may be MANY MULTIPLIES of that amount [at least initially].

Ascorbic acid is simply the best way [that I know of] to ingest those electrons [particularly longer-term].
