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.
Mechanism of Action
ETAS works by increasing the production of HSP70 — an intracellular protein produced naturally by the body when it encounters a stressor, such as extreme heat.*
HSP70 has many beneficial functions. It repairs damaged cells, tips the balance from excitatory cytokines to inhibitory ones and serves as an antioxidant.*,, Unfortunately, the heat shock response to stressors of all kinds decreases with age., Human clinical research has shown that ETAS significantly increases the expression of HSP70 at a dosage of 100 mg elemental ETAS per day.* (The commercially available form of ETAS is 50% elemental ETAS, requiring a dosage of 200 mg per day.)
ETAS is a natural ingredient derived from asparagus, which has been safely consumed as part of the food chain for at least 5,000 years. A 90-day toxicological study found no significant adverse events and confirmed the ingredient’s safety.
