Name: ROOK Glycine
Brand: ROOK

Question 1

What makes ROOK different from other supplement brands?

Accepted Answer

ROOK uses exclusively branded, patented ingredient forms — Ferrochel® iron bisglycinate and TRAACS® magnesium bisglycinate — with published clinical data on absorption and efficacy. We do not use proprietary blends, and every batch is third-party tested for identity, potency, purity, and contaminants. Our formulas are designed around bioavailability, not label claims.

Question 2

Why do you only have three products?

Accepted Answer

We believe in doing fewer things exceptionally well. Each ROOK formula targets a foundational nutritional need where the form of the ingredient dramatically impacts results. Rather than launching 50 SKUs with generic ingredients, we focus on three formulas where premium ingredient selection makes a measurable difference.

Question 3

Are ROOK supplements third-party tested?

Accepted Answer

Yes. Every batch of every ROOK product is tested by an independent, ISO 17025-accredited laboratory for identity, potency, purity, heavy metals (arsenic, cadmium, lead, mercury), and microbial contamination. We will publish Certificates of Analysis (COAs) for each production lot.

Question 4

What does 'branded ingredient' mean?

Accepted Answer

A branded ingredient is a patented, trademarked raw material produced by a specific manufacturer with published research supporting its quality and efficacy. Examples include Ferrochel® (chelated iron by Albion/Balchem) and TRAACS® (chelated minerals by Albion/Balchem). Branded ingredients provide traceability, consistency, and clinical validation that generic commodity ingredients cannot.

Question 5

When will ROOK be available to purchase?

Accepted Answer

ROOK is launching on Amazon in Summer 2026. Join our email list to receive launch-day pricing and early access.

Question 6

Are ROOK products vegan or vegetarian?

Accepted Answer

All ROOK products use vegetarian HPMC (hydroxypropyl methylcellulose) capsules. Our formulas are free from gelatin, dairy, soy, gluten, eggs, nuts, and shellfish.

Question 7

What is cGMP manufacturing?

Accepted Answer

Current Good Manufacturing Practices (cGMP) are FDA regulations (21 CFR Part 111) that establish minimum quality standards for dietary supplement manufacturing. These include identity testing of raw materials, potency verification, purity testing for contaminants, and documented process controls. ROOK products are manufactured in FDA-registered, NSF cGMP-certified facilities.
