“Adrenal extracts have been recommended and successfully used for a variety of health challenges that involve low adrenal function, including asthenia, asthma, colds, burns, depletion from infectious diseases, from colds, coughs, dyspepsia (poor digestion) early Addison’s disease, hypotension (low blood pressure), infections, infectious diseases…neurasthenia (low energy/weakness), tuberculosis, light-headedness and dizziness, and vomiting during pregnancy”

From “Practical Organotherapy,” H.R. Harrower as quoted in "Adrenal Fatigue The 21st Century Stress Syndrome," by James L. Wilson, N.D.,D.C, Ph.D.

These extracts are used to replenish and eventually normalize adrenal function. An advantage over cortisol hormone replacement is adrenal cortical extracts can be discontinued once they have done their job of repairing adrenal function. 

Essential Therapeutics uses only the purest, highest quality nutrients. Quality and purity are an obsession with us. Our products aren’t the cheapest priced products on the market, but we learned years ago that you get what you pay for. We don’t and won’t use cheap ingredients! Our formulas and products are based on clinical trials, experience and ongoing research. We seek out the finest ingredients on the market for our formulations.

We are dedicated to providing you with high quality pharmaceutical grade supplements specially formulated for people who are sensitive to the fillers and other additives that are used in many products. Only the purest amino acids, essential fatty acids, vitamin, minerals and herbals, are used in these formulas.

Essential Therapeutics products are produced in licensed manufacturing facilities that strictly adhere to current Good Manufacturing Practices (cGMP's). Products provided in tablet, capsule, and powder form are made in a manufacturing facility licensed by the State of California as a drug manufacturer and food processor and registered with the Food and Drug Administration as a drug manufacturing establishment. The facility is also approved by governmental agencies in the United Kingdom, the European Community (EC) and Australia to manufacture a drug product. Current GMP's and written standard operating procedures (SOP's) are strictly followed through all stages of production to produce products that meet or exceed United States Pharmacopeia (USP) standards.

Active ingredients used in Essential Therapeutics products are selected based on their purity, bioavailability, documented actions, and safety characteristics. USP materials, i.e., those meeting USP standards, are used for those nutrients where this standard exists. Raw materials are purchased exclusively from reputable vendors who provide detailed Certificates of Analysis for every lot of material. These certificates certify that active components, toxic elements, and microbial content are within specified acceptable parameters. Purity and potency of selected raw materials are verified through independent testing laboratories. All incoming raw materials undergo quarantine, inspection, and evaluation.

On-site laboratory personnel evaluate physical characteristics of each finished product including hardness, disintegration, moisture balance, friability, and pH. Purity and potency of finished product is independently verified through outside commercial laboratories using a randomized ingredient and batch testing program.

Essential Therapeutics products are free of artificial flavors, preservatives, and colorings. Naturally-derived, inert excipient materials, including cellulose-based excipients, vegetable-derived magnesium stearate, and silicon dioxide are used in very small amounts as tableting and encapsulation aids. Tableted products are protected with an inert, water-soluble cellulose coating that dissolves readily upon ingestion, thus facilitating tablet disintegration time.
