Is there any reason a B-Complex with C (plus multi, plus iron (every other day or so), plus fish oil) would be not-ok while BFing? Can you OD on B vitamins?
BTW, I posted this on the mommy board:
I was having major numb/tingling sensations in my toes and attributed this to yet another wierd PP phonomenon. I take a multi-vit. and iron and recently added B-complex because I've been so tired PP I thought it might help (I think it did). My toes got better right away, but I didn't associate the two until I read this last night:
Q: I am a retired doctor with type 2 diabetes. Metformin has kept my blood sugar in the normal range for 10 years. Despite good control, my foot numbness was getting worse. I was also a little unsteady on my feet.
In reviewing the medical literature, I discovered that metformin interferes with vitamin B-12. I suspected I might be deficient in this nutrient, so I started oral vitamin B-12.
Within a week, I noticed a sharpening of my mental capacity. I stopped having any trouble walking, and my foot numbness has decreased.
Many older diabetics take metformin, and their subtle neurologic and mental deficits may be overlooked but could be treated.
A: Thank you for pointing out that metformin (Glucophage) can deplete the body of vitamin B-12. This can lead to serious neurological symptoms if not corrected promptly. http://www.chron.com/disp/story.mpl/life/3494451.html
