Proprietary extract of Asparagus officinalis
ETAS is a proprietary ingredient derived from the tough lower portion of asparagus stalks, which has the unique ability to increase the production of heat shock protein 70 (HSP70). Double-blind, placebo-controlled research has shown ETAS effectively:
Increases quality of sleep
Alleviates occasional stress by improving heart rate variability
Raises cognitive performance, reduces fatigue, and improves the stress response
The extraction process used to create ETAS results in unique hydroxymethyl furfural derivatives — particularly asfural — that are not contained in raw asparagus extract.
