Hi I am a new member joined recently. After discovered Freddd's B12 protocol 2 weeks ago, I decided immediately to give a try since I already had most of his supplements at home even though my methylB12 sublingual 2000mcg is from MRM not one of the five-star brands performed by Freddds, I don't have adoB12. Now, I am waiting for my orders coming from iherb.com. In my case, 1) I have been taking nature-made b complex consistently for years up to today. 2) I have tried methyl b12 sublingual 2000mcg from MRM together with other ingredients included in Freddd's in the past without noticeable effect, good or bad. 3) I started the Freddd's two weeks ago, with both metafolin 800mcg and methylB12 2000mcg sublingual as single dose. My positive even though limited lift from Freddd's protocol must come from metafolin 800mcg. 4) My only noticeable side effects are slight headache, which still persists and slightly faster heart beats, which seems subsiding with one 90mg potassium pill. 5) What to increase or decrease next? I am thinking about increase metafolin from 800mcg to 1200mcg since metafolin seems THE ONE made the difference to me not methylb12. If there is side effect, I would consider add more potassium and/or more methyl and/or adob12 to balance it out. Any thoughts?
