Vit C effects on blood glucose levels? Why no lipo reading?

[exitium]

Im just curious, had some basic labs done a couple weeks ago. Non fasted glucose was high. I dont remember exactly but based on timing of my appt there is a very good chance I had 2-4 grams of ascorbate within an hour of my blood draw. Would this have any bearing on my blood glucose?

I read somewhere that vitamin c raises blood glucose levels. I researched this before starting vitamin c because I WAS hypoglycemic at the time.

Hi Exitium
I believe the answer is yes it will show you have a raise in your glucose levels as the Vit C is read as glucose- this thread i believe is in depth.

The answer is no.

However, did you just have a meal, or when was the last meal? Do you remember the numbers?

Yes, I had eating about 90 minutes before.

Werent you trying to do some testing with a glucose meter to contrast/compare oral VC compared to lipo VC? If a dose of VC was causing glucose meter to register higher glucose then wouldnt that be the same?

[ofonorow]

Yes, but the increase was after ingesting about 4-5 grams at once, and peaked around minute 20. After an hour, the numbers were almost back to the starting point. And different vitamin Cs peaked at different values, which weren't all that high (compared with intravenous vitamin C).

Much stronger (and longer) effect by eating (real glucose).

Owen,

In some older threads, you reported an experiments on measuring plasma Vit C levels, after digesting Lypo C packets using a freestyle lite blood glucose monitor. If I remember correctly, your experiment did not show any increase in the reading after digesting 5 packs, even showed a drop of 60 points from base line.

Here is my experiment. Recently, I am taking 5 packets of Livon Lypo C twice a day and about 24 g of L-Ascorbic acid in four doses (why ? , that is another thread). In the morning session, I take 5 Lypo and 5.5 g of Ultra C. My measurements using the freestyle lite, before and after, showed only a diff of 10 point. However, later in the day when I took 5.5 g of Ultra C alone I got a spike of ~ 40 points.

Then I got hold of an NIH study (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3725640/), which suggests that this method is not suitable for plasma concentrations below 50 mg/dL.

Any thoughts ?

Assume I am old and dense. Do you have a link to the thread with your experiments/data?

Thanks for that pubmed study which "justifies" our like experiment. Here is the link to our crude measurements topic: http://www.vitamincfoundation.org/forum/viewtopic.php?f=10&t=10603

I never fully understood why the Lypo-C blood measurements failed to show vitamin C (as they did after the UltraFINE ingestion) An expert I consulted said that the encapsulating liposome should not effect the glucose meter, it should be able to read the C encapsulated or not.

Also these measurements are really only valid or meaningful after fasting - when waking up in the a.m., and you need to take a couple of baseline readings, say after drinking a glass of water, etc. before starting. But if you can do this, I would really appreciate other readings of Lypo-C (and I may do some readings of our new China-FREE Quali-C liposomal.)

I did not do a details experiment, as you did, just a couple readings. they are below:

7:00 AM 16 oz of water.
7:15 AM: base line 96 mg/mL
7:20 AM; 5 packs of Livon Lypo + 5.5 g of Ultra C
7:35 AM: Reading: 106 mg/mL
7:50 AM : Reading: 108 mg/mL

2:00 PM : baseline 105 mg/mL
2:05: PM 5.5 g Ultra C
2:20: reading: 146 mg/mL

Meter used: Freestyle lite.

[ofonorow]

Yes those readings do indeed seem strange. (I supposed I need to start pricking my fingers again. See if this is repeatable.)

Question: Why would the blood reading be so much higher for ultraFINE C alone - with out PLC (phospholipid choline)?

Time for a brainstorm about what may be going on before I shared my expert's comments with Johnwen (The expert actually worked on glucose meters, in a previous life.)

Guess #1 Perhaps when you take the ultra with the Livon (PLC) it gets emulsified something like the aloe/kiwi gel? Leading to.. #2

Guess #2 Perhaps Liposomal/PLC is immediately taken up by the liver, and the vitamin C is released more slowly out of the liver over time?

Guess #3 My expert is wrong and the nano sized bubbles can shield their contents from the electric shock created by the glucose measurement?

Now I'll look for his comments.

Additional Info:

Hydration: In every Vit C dose (lipo or Ultra C) I take at least 16 oz of water. If we assume that in the morning we are a little dehydrated, 15 min after taking 16 oz of water (no vit C), may not be getting me fully hydrated. Where as, at 2 PM I have numerous sources of liquid and, probably a bit more hydrated (?). So the base-line may be off a little.

Ph: Yes, that makes sense to me. Lipo being neutral (I presume) and the 2 PM Ultra C intake totally acidic, can throw off balance the meter's electrode response, specially when we are comparing the two.
