Has anyone noticed a difference in their energy level following a change from Erfa to Armour or vice versa?

I did when I first swapped from erfa to armour, I went down a bit and had terrible headaches as well, fortunately it didnt last too long. I think its the slightly different strength that does it, body soon adapts though

I do exchange them sometimes ,if Armour not available but I have never noticed any difference nor to my bloods.

Thanks for your responses. I am experiencing problems with Erfa and I'm taking more and more with little effect. I'm beginning to think that the change is a co-incidence and that something else is going on.
