B2 deficiency? I have never looked at that. I looked at the food sources of riboflavin and it is nearly our regular menu, so there is that.
I started with B12 injections for extra energy, and that worked. Then I discovered it did positive things for my depression. Since it is OTC, I have been doing regular injections with my doctor's approval. (Note: I can not stick myself with needles so the husband does it. I still wince! LOL)
B2 is a rare one, not usually done, but I asked to make sure. Like phosphate I've got tons of it in my regular diet, but like it it doesn't get thru, so I've been severely deficient in it, and both have a lot to do with energy. Phosphate can't really be supplemented and it's a struggle to increase it via diet, e.g. I already eat lots of pumpkin seeds anyway, but now I have to soak them. B2 I was taking the an enormous dose to no avail, so after loads of research I've doubled even that to the max. dose used in studies.
B2 and phosphate are connected, as one B2 form is riboflavin-5-phosphate. You'd think - and one pharmacist suggested it - that w'd've been good for phosphate, but it is the form I am already taking, and actually a supp-expert online (in a 3h podcast just on riboflavin) offered the thought that if it's not getting thru, then maybe the regular form will work better....
I've also restarted by B12 inj. as methylcobalamin to stop it from getting lower, but it's never done anything for energy.
My docs knew nothing about the injections or actually hardly anything I'm taking, and when I asked if they think it's OK to take B3 as nicotinic acid high dose for my triglycerides they sheepishly smiled 'no'. I'll try to remember next time to ask the other way round if they know any problems about high dose B3 as nicotinic acid, so they lose face less... In the meantime I've researched further and found people saying it can be dangerous for liver, and TMG needs to be supplemented in the same amount, so I'm doing that and getting those bloods checked soon.
I don't ever wince with those, but I do prefer my wife jabbing me! I've only occasionally winced like from spine injections and a spinal tap whilst sitting may have started with wincing, I can't remember, but I ended up shouting out several times... (the first one didn't work, so in it went again...) but still no anxiety after, thankfully, I bet thanks to a nurse holding my hand.
If my wife weren't there I sposed I'd have to practice it by jabbing in oranges...
