I realized there was another variable besides Methyl vs. Ado/Methyl: dosage. I was using 3x/day. The Ado/Methyl has the injected equivalent of 0.5mg methyl & 1.5mg ado, so I was getting 1.5mg + 4.5mg = 6.0mg total, per day. The methyl-only oil has the equivalent of 0.6mg, so 1.8mg total per day. Maybe that just wasn't enough, in the absence of the adenosyl. I don't know how "interchangeable" methyl and adenosyl are, but I wonder if "lots of methyl" (with weekly/whatever adenosyl) might have worked as well as the daily 6mg dose of methyl/adenosyl?
I will find out when the group buy comes through!
Thanks
@Freddd, I'll keep that in mind when I start boosting my methyl. So even if the sublingual is on your mucosa for an hour or more (e.g. between lip and gum) you still saw only 15-20% absorption?
Sure would be nice if there was a more effective delivery mechanism. B12oils.com has an adenosyl-only oil, with presumably the same high 80% absorption rate that they've seen for the methyl. I don't know the dosage in a squirt, but if it's 1.5mg like the ado/me oil, it would take 5-7 squirts to get the 7.5-10mg injected equivalent you're looking for. Effective but pricey.
@skwag, your Chinese supplier doesn't sell pure adenosyl crystals, do they? I can't find any on alibaba. It would be nice to be able to mix up some adenosyl spray.
