Would taking dosage w/ food alleviate some BT issues?

This forum will focus on the interesting topic of titrating oral vitamin C intake to so-called bowel tolerance, the point just prior to the onset of diarrhea

Would taking dosage w/ food alleviate some BT issues?

Post Number:#1  Post by Cobraman » Sat Feb 12, 2011 3:54 pm

I have looked over old posts and cannot seem to find an answer to this question: Would it be better to take all doses of vc w/ a protein or fat(minimal carbs) to both maximize absorption due to protein, and get a steady even flow of vc because of it being combined w/ food. It would make sense that max absorption would be on an empty stomach, but this may be too much too fast. It would be more convenient to take a somewhat larger dose w/ food to even the flow. Let me know what you think.

If you're eating high protein meals, yes.

If you're eating hi carb, high sugar meals, no.

Protean protects C -- so you can absorb more of it.

Sugar competes and encourages oxidation of C, which means it'll absorb even poorer which means you'll reach bowl tolerance even faster.

That's my understanding anyway.

Not certain of the answer. Anecdotally, over the years people taking vitamin C and lysine drink mixes at therapeutic dosages reported "best results" taking about 20 minutes prior to meals. (Less gas and discomfort I presume.)

As Hickey/Roberts report in THE RIDICULOUS DIETARY ALLOWANCE (lulu.com/ascorbate) some amount of ascorbic acid is absorbed through the stomach wall, so almost instantly.

For that AA that reaches the gut, between 1/2 (Pauling) and 4/5 (Catchart) is lost, i.e., degrades or is not absorbed so is not bioavailable. (Since some is absorbed into the blood stream through the stomach lining, the lost in the gut may even be greater.) It seems that for this portion of the oral vitamin C intake, traveling into the gut, then yes, taking with protein (and avoiding carbs) would seem prudent.

Another variable to keep in mind is transit time in the stomach. According to Dr Levy in one of his books (Optimal Nutrition) carbohydrates stay approximately 2 hours in the stomach, proteins last four hours, and fats stay in the stomach approximately 6 hours. From this one might conclude that the optimal time to take vitamin C is 2 to 4 hours after a meal, after the carbs have passed out of the stomach.
