All Anecdotal, but a couple months ago I was feeling I wasn’t quite recovering as well as I wanted. Failed some workouts I thought I shouldn’t have. Could have been that I didn’t do as much volume over the winter and early spring because of the shitty weather.
But, I did some blood tests - Ferritin of 38, Low Folate, Low B12. Last year by mid summer my Ferritin had dropped to 30, so I started supplementing for all three. 2 x Vitron C every other day (Vitamin C is important for Iron Absorption), plus a Thorne Multi that has Folate and B12 in it. There are also some studies that show better absorption from iron every other day because of the hepcidin response.
I also take Thorne Magnesium, Vitamin D every night. Fish oil morning and night, but none of that is new.
I’m a couple months now, and have been recently having the feeling that things are starting to click again. Even when I have some hard workouts, I’ve been having the kicking ass and taking names feeling again.
So - no idea if it’s actually related. But, subjectively I’m feeling better than I was a couple months ago.
(Warning: Don’t supplement iron without blood tests, too much is a bad thing!)
