I'm now wondering if I'm sensitive to folic acid. Been not feeling much on the protocol this time around. Been taking 1/8 Jarrow glass bottle MCbl and 1/8 Folapro. But have been taking a Jarrow multi an hour or so before which contains folic acid (http://www.iherb.com/Jarrow-Formulas-Multi-1-to-3-with-Lutein-Iron-Free-100-Easy-Solv-Tablets/245) The B12 is Mcbl and only 16.66 mcg per tablet and 133 mcg of folic acid per tablet. Yesterday I didn't take the multi at all and was very wiped out this morning. I could have slept all day I think. I got to work and took about 2.5 mg sublingual pregnenolone and 2x my 99mg potassium chelate and felt much better within 10 minutes. I wish I had taken them a little further apart so I could know which one (assuming only 1 helped) helped me the most. I knew I was having brain fog so I took the preg...then occured to take the K.
