I may be wrong on this but doesn't a "time release" have to be a pill or capsule rather than a spray. How can you slow the release of a liquid? Know what I mean? If it works great, it just may not make a difference as opposed to any other spray or sublingual form.
As for lucid dreams I have read about that, where you are aware that you are dreaming. Have you experienced this? On some level I'm not sure I'd want to experience that but it sounds kinda cool.
Here's from Source Naturals PDF File:
The First Timed Release Sublingual
Due to the multi-layered structure of the tiny lipospheres,
nutrients are gradually released for extended
periods of time, maintaining optimal dosage throughout
the day or night. This combined with a faster onset
of the active ingredients – usually within 15 minutes –
makes NUTRASPRAY the most bioavailable delivery system
for nutritional supplements today, and the first
truly timed release sublingual.
The lipid micro-encapsulation process is based on
years of research in liposomal technology. The result is
NUTRASPRAY, a proprietary system to deliver nutrients
in the most efficient manner. This sublingual oral
spray is a liquid suspension of liposomes, which are
nutrients encased in very complex microscopic lipid
spheres, 1/50th the diameter of a human hair. A highly
purified natural lecithin forms the membrane of
these lipid spheres, which are able to move easily
through the lipid environment surrounding the capillaries
in the mouth. Lipospheres then gradually release their nutrients into bloodstream.
