Like many others, my insulin choices are horribly limited by insurance. FIASP and Apidra just aren’t options right now. Since FIASP simply has niacinamide (vitamin B3/niacin) added to it, has anyone seen faster insulin activity simply by taking a niacin supplement additionally? I assume the full-flush variety would be more effective, if it at all. This is pretty much impossible to search for because you get flooded with FIASP topics and web results.
I have reason to be weary of anything with B vitamins because I already have a toxic load of B12. It’s a chronic inflammation marker (which is what’s causing my slow insulin absorption issues, too). Straight niacin shouldn’t be a problem, but I’d love some feedback if it’s worthwhile before trying it.
