"Under the tongue": https://en.wikipedia.org/wiki/Sublingual_administration
I'd be very interested in that product!
Are you not in effect using less product and wasting very little?
We originally used to offer capsules, but created the first sublingual tablet to offer the most bioavailable and readily absorbed NMN on the market.
Capsules are degraded upon digestion and converted to NAM in the liver.
The enzyme cd38 prevents any NMN from passing into the bloodstream and on to the cells and tissues.
We do not anticipate transitioning back to capsules in light of research on the subject.
Thank you for your interest!
