Vitamin B6 as pyridoxal-5-phosphate is included as the active form of B6 to support the conversion of 5-HTP into serotonin.
According to the manufacturer, this multi-mechanistic formula is designed to support natural sleep onset without providing melatonin directly. Instead, it supplies calming compounds and nutritional precursors involved in the body’s own melatonin production pathways.
Suggested Use
As a dietary supplement, take 2 capsules 30 minutes before bedtime, or as directed by a healthcare practitioner.

Lumbrokinase Circulatory System Support capsules Allergy Research Group
From $61.39
Overview
Lumbrokinase Circulatory System Support is a systemic enzyme formula designed to support healthy circulation and cardiovascular function. Lumbrokinase is a group of proteolytic enzymes derived from the earthworm Lumbricus rubellus, traditionally studied for its role in supporting fibrin balance and normal blood flow.

Overview
Adrenal Cortex 100 mg 100 capsules is a natural glandular formula designed to support healthy adrenal function, stress resilience, and endocrine balance. Each capsule provides 100 mg of bovine adrenal cortex tissue in a lyophilized form, offering targeted adrenal support in a simple, practitioner-style formula.
This product is intended for individuals seeking a freeze-dried adrenal cortex supplement to help support the body’s stress-response pathways and adrenal nourishment. Sourced from range-grazed, government-inspected animals in Argentina, it provides focused glandular support without added hormonal blends or complex stimulant ingredients.
Key Benefits
- Supports healthy adrenal function and stress resilience
- Provides 100 mg of freeze-dried bovine adrenal cortex per capsule
- Targets adrenal nourishment in a simple glandular formula
- Supports metabolic, endocrine, and immune-related stress pathways
- Lyophilized to preserve delicate biological compounds
- Sourced from range-grazed, government-inspected animals in Argentina
Supplement Facts
Serving Size: 1 Capsule
Servings Per Container: 100
| Ingredient | Amount Per Serving | % Daily Value |
|---|---|---|
| Adrenal Cortex Tissue (Bovine, Lyophilized) | 100 mg | Daily Value not established |
Other Ingredients: Hydroxypropyl methylcellulose, microcrystalline cellulose, silicon dioxide, magnesium stearate.
Ingredient Breakdown
| Ingredient | Role in the Formula |
|---|---|
| Adrenal Cortex Tissue (Bovine, Lyophilized) | Targeted glandular ingredient used to support adrenal nourishment, stress-response physiology, and endocrine balance |
How It Works
Adrenal Cortex provides freeze-dried adrenal cortex tissue, the portion of the adrenal gland associated with the production of steroid hormones involved in the body’s response to stress, metabolism, and immune regulation. By focusing specifically on adrenal cortex tissue, this formula is designed to provide targeted adrenal glandular support rather than broad endocrine stimulation.
The tissue is lyophilized (freeze-dried), a process chosen to help preserve delicate compounds that may be sensitive to heat. This helps maintain the integrity of the glandular material and makes the formula more aligned with traditional practitioner-grade glandular preparations.
Because the adrenal glands play a central role in the body’s adaptation to physical and mental stress, this formula may be especially relevant for those looking for a natural adrenal support supplement for stress resilience, endocrine balance, and adrenal nourishment. Its single-focus composition also makes it easy to include in more tailored wellness protocols.
Suggested Use
As a dietary supplement, take 1 capsule daily with a meal, or as directed by a healthcare practitioner.
FAQ
What does Adrenal Cortex support?
It is designed to support healthy adrenal function, stress resilience, endocrine balance, and adrenal nourishment.
What form of adrenal tissue does this product contain?
It contains bovine adrenal cortex tissue in a lyophilized, freeze-dried form.
Why is the formula labeled as adrenal cortex?
The adrenal cortex is the outer portion of the adrenal gland associated with steroid hormone-related stress and metabolic pathways, so this formula focuses specifically on that tissue.
How should this product be taken?
Take 1 capsule daily with food, or as directed by a healthcare practitioner.
Are there any important precautions?
Yes. It must be taken with food, as GI distress may otherwise occur. If GI distress occurs even with food, discontinue use. Higher-dose or long-term use should be guided by a qualified healthcare practitioner.
Storage
Store in a cool, dry place, tightly capped, away from light. Keep out of the reach of children. Use only if safety seal is intact. Variations in product color may occur.
