@ LionHeart,
Thanks alot for providing more info & the links.
According to the first link:
"In the fasted state, the median gastric pH was 1.7 and the median duodenal pH was 6.1. When the meal was administered the gastric pH climbed briefly to a median peak value of 6.7, then declined gradually back to the fasted state value over a period of less than 2 hr."Wow, 1.7 ; That's pretty low. Since the article you quoted was seeing effects on the Au nanoparticles at about pH 2 then I guess it is an issue that should be given some thought.
As far as when is the optimal time to take colloidal silver or colloidal gold I think there would actually be 3 choices: empty stomach, full stomach (with the meal), OR a specified amount of time after a meal (perhaps 45 minutes? +/- 15 min.)
As is often the case, it looks like a trade-off situation:
Empty stomach = Faster absorption but more
possible harm to the colloidal silver or colloidal gold due to extremely low pH.
Full stomach = Slower absorption yet less unfriendly environment but the colloidal silver or colloidal gold would still be in the somewhat unfriendly environment for a longer length of time (vs empty stomach).
Possibly the 3rd choice I mentioned could be a logical compromise. Set a timer when you finish a meal for 30 - 45 minutes & hope to sneak the colloidal silver or colloidal gold past the moat of acid before the pH gets back down into the extremely low ranges.
Another idea might be to take the colloidal silver or colloidal gold on an empty stomach but 15 minutes beforehand take an antacid or something that would raise the pH level in the stomach. Problem with that idea is who knows what that chemical could do to the colloidal silver or colloidal gold? Guess I would have to hire a chemist to help me figure that out
It could also be that colloidal silver stands up to severe acid conditions with fewer detrimental effects compared to colloidal gold?
However, IF our colloidal silver is being adversely affected by the acid then that could be a good reason to reduce with cinnamon extract rather than Glucose/Fructose (Karo).
In a different thread Kephra recently mentioned:
"There was some research done with metallic silver in an artificial stomach fluid bath (pH 2) which showed that a portion (25%) of the metallic silver was oxidized to silver chloride during the amount of time the researches thought it would remain in the stomach. They however had no way of measuring absorption." If the digestion of the phenols (from cinn ext.) that surround the silver particles only starts in the stomach and is then completed in the small intestine then at least we know that a significant portion of our silver is not being converted to Silver Chloride. Might take a few hours longer for the silver to make it's way into the bloodstream, but I see no reason why it would not be adequately absorbed by the small & large intestine.
LionHeart, do you use Colloidal Silver? I have not made or used colloidal gold yet so I don't know as much about it but I wonder if there would be a way to surround your gold particles with the polyphenols from cinnamon extract? Need to hire that chemist again
