Dear MrsD, You are a wealth of information. I am a newbie and can't thank you enough for distilling your knowledge of supplementation to all of us. This sticky has been tremendously helpful. I plan to begin using Vitamin B 12 (methylcobalamin) this week on an empty stomach as you suggest. My Armour Thyroid must be taken likewise (90mg). But I can't wait very long after awaking to take my first dose of Gabapentin (1500mg). Can all three of these be swallowed together without comprising their effects?
