I eat a lot of liver and oysters but still feel a noticeable increase in energy and wellbeing with supplemental b12 (Injections). Intestinal absorption of b12 from food sources is quite a complex issue, I first got into the topic when I was still vegan but I am not really up to date on the science anymore to be honest.Maybe someone else knows more here.Or does liver have a range of forms and likely cover my bases well enough anyway?
I think the nitric oxide scavenging properties are unique to the hydroxycobalamin form. It also stays in your body a lot longer and has some other interesting properties (cyanide antidote) .Since I haven't tried the sublingual methylcobalamin, which seems easier to come by, maybe that's worth a try too?
Methylcobalamin in higher doses always gave me skin issues and this weird, jittery form of energy. Not a big fan to be honest, but some people seem to do well on it.
Sure. The ones I have are just hydroxycobalamin, water, sodium chloride and acetic acid.The study Hugh pointed to was for intranasal delivery. I wonder if the same formulation could work for that?
Not sure how you're going to get it in your nose though
Those are the ones I'm using btw:
