Calea Zacatechichi

Possibly this is too far outside your normal range of products to be included, but there is something which virtually no one seems to sell, although it would have obvious and immediate benefits: a dry extract of Calea Zacatechichi.

Calea is a REM-sleep enhancer, meaning it increases the amount of REM-sleep, at the cost of less NREM-sleep. Apparently there are no known unwholesome side effects.

Normally, Calea is taken as herbal "tea", but it is so bitter that most first-timers vomit instantly upon tasting the tea. It takes real effort to down a cup.

I have made alcohol-based tinctures of it, and these retain the REM-boosting effect and are much easier to ingest since the amount is so small, but a dry extract would be preferable.

Just a thought.
