How long after you put the powder under your tongue do you get the elevated heart rate? If it's a few minutes or less, then that's evidence that you can absorb more than 30 mg at a time sublingually. That's especially true because the effect only lasts for a minute or two. It's hard for me to believe that the window of effect would be so narrow if you were absorbing the NVM through the digestive system.
Yes, it is within a minute. That is why I originally posted about it the first time - because it shows that far more than 30 mg is absorbed sublingually (at least with the powder).
With the normal 125 mg dose they say you get with the little plastic scoop, I can feel an effect, but not enough to notice increased heart rate.
It is only when I use higher dosages that I notice elevated hr.
250 mg of the NAD+ does it for me. For NMN, I might notice a little increase at 250 mg, but get it fairly strong when I do 2 250 mg spoonfuls back to back.
I know the research on sublingual tablets show that 30 mg or so is the maximum that is instantly transported, after which additional dosage yields diminishing returns.
That is a tiny tablet that depends on saliva to dissolve it. Too much drug/saliva, and you swallow more and more.
The powder is much different. It spreads across a much wider area, and dissolves instantly with little or no saliva and none swallowed.
Personally, I'm very happy a powder is the most effective, as no-one can make a special pill they combine with pterostilbene or whatever, and charge 10x more for it.
With competition, the price of powder will be driven down by bulk suppliers and we will get much better pricing than if it was a pill.
