In the last decade and a bit I've been deficient in 3 B vitamins.
First up was B1 (Thiamin) in 2002/2003
Next up was B12 in 2014
Now it's B9 (Folic acid) in 2015
There's something weird going on in my body that uses up the B vitamins seemly faster than they should!
I'm going to be taking the Folic acid for a couple of months and I'll keep taking my supplements too... I just need to take them every morning! Just need to get back into the habit again now 'cos I definitely notice the difference when I don't take them!
