ATP Cofactors -- Ferventer was right!

I have added vitamins B2 and B3 to my daily supplements and was able to reduce my Lugol's from 65 drops per day to 26 drops per day. Yippee! I started with Douglas Laboratories B-Complex which contains 20mg B2 and 50mg B3, since that was what I had on-hand whilst awaiting my order of ATP Cofactors from Optimox. Took 1 Cofactors tablet on Saturday, 2 Cofactors tablets on Sunday, and 3 Cofactors tablets on Monday and am very tired. I think there may be too much filler in the Optimox product for my poor digestion. I grind the Cofactors tablets to a dust with my mortar and pestle and add it to a little bit of yogurt with breakfast. The Douglas Laboratories are capsules and it appears that my body can digest these easily. I was taking 3 per day of the Douglas B-Complex and had much energy even though the dose on the bottle says the capsules contain only a fraction of the Optimox product. Any ideas or other brands that I should try? Thanks in advance for your help.
