Vitamin C and blood sugar levels (by meter)

(Bob M) #1

I have covid. So, I’ve been taking some vitamin C. Specifically, 2 grams at lunch. See the following:

That peak lasted waaaaaay longer than it should have, and I think is higher than it should be based on the many other times I’ve eaten about the same meal.

Oddly, I ate a sandwich (ham, cheese, mustard on an egg white “tortilla”), and my blood sugar went DOWN.

I think this is what is happening:

I think the meter is showing higher blood glucose, and that’s not correct.

I did not check with a pinprick meter.

So, if you’re taking larger doses of vitamin C, the meter might read incorrectly.

Well, that didn’t work out. I had two “sandwiches” (meat, cheese, mustard, zero-sugar ketchup, egg white tortillas, fermented pickles) for lunch, along with 2 grams of vitamin C.

The result?

My blood sugar is totally flat.

UGH! I’m wrong – again.

Yesterday, I had milk + protein powders, which I did not have today. I’ve had that at other times, though, and didn’t get that spike. I’d love to test:

  1. milk + protein powders
  2. water + protein powders
  3. individual protein powders

Protein powders = l-citrulline, creatine, and collagen peptides.

Unfortunately, I only have a few hours on this CGM sensor and might not get another one for a while.

Edit. I ate about 10 am.Doesn’t get much flatter.

Bob, that is some admirable blood sugar control. :+1::sunglasses:

That’s my impression too. Checking the y-axis… These variations are minimal excursions, not the uncontrolled spikes associated with severe insulin resistance.

@OldDoug and @SomeGuy Thanks.

When I wasn’t on Jardiance, my blood sugar was remarkably stable while eating keto.

(The dots on the graphs are because you needed to read the sensor using a device, and that’s when it was read. You’d then download the data to computer. Old school, compared to the new ones on phones.)

I think something is up with me – maybe covid is causing issues? Or maybe the stuff I’m taking (like multiple grams of vitamin C) to “help” with covid? Possibly in combination with Jardiance?

Case in point: We had some quiche left over from a Mother’s day event. So, on the left, I ate 3 pieces of quiche, and got basically no blood sugar rise. On the right, I ate the last two pieces of quiche and got a huge rise that lasted around 3 hours.

That “today” is actually from yesterday, and “yesterday” was 2 days ago. My sensor ended last night.

Right now, my blood sugar is all over the map. Considering that I ate 3 pieces of quiche the day before and didn’t see anything, I was shocked to see the large spike for a smaller amount of quiche.

And this freaking covid is taking a while. I don’t feel THAT bad, but I keep getting cold then hotter (no fever though), then cold, repeat ad nauseam. Days aren’t too bad, but nights aren’t great.

Apparently you are better off eating 3 pieces of quiche instead of 2. :wink:

On a more serious note… Illness (cold, flu, various viral infections) can easily affect serum glucose levels. Yes, it’s odd (interesting?) that you get these variations in measured glucose. But I’d still submit for your consideration that (a) the excursions seen are relatively tame and (b) they are short-lived, supporting the conclusion that you have solid homeostatic insulin/glucose control function.

But with your current COVID struggle - which sounds miserable - you might expect all kinds of out-of-the-usual glucose behaviors. Hopefully that’s the least of it!

[E.g., My wife and I both shared a nasty cold (from the grandkids) last year and our HbA1c levels rose sharply. Then both receded again to our normal levels. Not COVID but lots of congestion/sore throat response to the virus they lovingly shared.]

@Angel143 Well put. :wink:

Ever tried Ivermectin. Not advising you but I take it zero effects. They shut down the person that tested it for Covid it works. If you need more information I can send podcasts of top retired doctors that brought this to light.

Ivermectin vs. Placebo in a trial measures metabolic effects, I’ve read Ivermectin out performs placebo! It’s well known it’s almost completely inert. (Similar effects to the microbiome as Vitamin C btw). It’s a failure of the healthcare industry to need a f-ing prescription for it.

Bob M I always thought my green tea, that had Vita C as a preservative, screwed w/ my blood sugar.
