I've already determined that niacin (500 mg when I take it) seems to trigger hypos. Instead of 1U insulin dropping me 25 mg/dL, I can expect 50 to 65 (after 1.0 to 1.5 hr using Humulin-R!) when I've recently done niacin.

Now I'm finding vitamin C somehow triggers hypos. I'd suspected this before, and recently observed it again.

e.g. last night: BG = 91 mg/dL @ 23:45, virtually no IOB. Had 1x Emergen-C packet -- 6g carbohydrate (which is worth a 15 mg/dL bump) and 1g vitamin C -- and a little stevia powder.

I've set my Lantus to give me ~ 10 mg/dL drop overnight. Yet this morning I awoke with 54 mg/dL.

It's not just the Emergen-C or stevia, either: A few days ago, 4g of vit-C with rose hips coincided with an excursion to 41 mg/dL. I forget what I'd eaten, but I understood it well and have no reason to question the bolus.

Odd. Just thought I'd share.

My lipid doc warned me years ago that Niacin makes some have unstable (high or low) blood glucose. It is well known in professional diabetes circles.

I'd heard of niacin having a hyperglycemic effect, but not hypo. Vitamin C... I'd not heard anything.

Then, again, I was averaging 65 g/day of Vitamin C during the two months before DX. Kind of makes me wonder...
