JRK SUPPLEMENTS

Three Ingredients. Full Transparency. No Exceptions. Nutraceutical standards from the start.

Engineering Better Supplements

Every JRK formula contains exactly three active ingredients. No more, no less. We believe supplement complexity is often a cover for poor quality control. Our constraint is our quality commitment: three ingredients maximum, full dosage disclosure, third-party tested, nothing hidden.

Engineering Specifications

Every supplement in our workshop follows the same engineering principle: maximum effectiveness through minimal complexity. Three Ingredients. Full Transparency. No Exceptions. Nutraceutical standards from the start.

Three Ingredient Maximum

We limit every formula to three active ingredients maximum. This constraint forces us to select only the most essential, well-researched nutrients. More ingredients mean more variables, more potential interactions, and more opportunities for quality control failures. Three is our engineering limit.

Full Dosage Disclosure

Every single ingredient appears on our label with its exact dosage. No proprietary blends. No hidden amounts. No "other ingredients" section filled with undisclosed quantities. You know exactly what you're getting and how much of each compound is in every capsule.

Bioavailable Forms Only

We use the most bioavailable form of each ingredient, not the cheapest. Magnesium glycinate instead of magnesium oxide. Zinc bisglycinate instead of zinc sulfate. Selenium L-methionine instead of sodium selenite. Your body recognizes and absorbs these forms more effectively.

Research-Based Dosages

Every dosage in our formulas matches the amounts used in published research studies. We don't underdose to save money or overdose to appear more potent. We use the exact amounts that clinical research has shown to be effective for the intended purpose.

Component Analysis

Each product contains exactly three active ingredients, chosen for their synergistic effects and research-backed dosages. No fillers, no unnecessary additions, no compromises.

Mineral Triple supplement bottle

Mineral Triple

Three essential minerals working together for enzyme function, immune support, and nutrient processing. Each mineral is in its most bioavailable form for maximum absorption and effectiveness.

Active Ingredients:

  • Magnesium Glycinate - 200mg
  • Zinc Bisglycinate - 15mg
  • Chromium Picolinate - 200mcg

Magnesium glycinate supports enzyme and muscle function. Zinc bisglycinate aids immune and cellular repair processes. Chromium picolinate assists with nutrient processing. Every ingredient at research-supported dosages.

Recovery Triple supplement bottle

Recovery Triple

Antioxidant recovery support through three powerful compounds. Each ingredient is selected for its unique mechanism of action and proven effectiveness in protecting cells from oxidative stress.

Active Ingredients:

  • Selenium L-Methionine - 200mcg
  • Vitamin C (Acerola Extract) - 500mg
  • Reduced L-Glutathione - 100mg

Selenium L-methionine provides the organic form with highest tissue retention. Vitamin C from whole food acerola extract. Reduced L-glutathione is the body's primary endogenous antioxidant. Full disclosure, tested before shipping.

Bone & Joint Triple supplement bottle

Bone & Joint Triple

The three nutrients most consistently studied together in bone mineral density research. This combination represents decades of clinical research into bone health and mineral absorption.

Active Ingredients:

  • Calcium Citrate - 400mg
  • Magnesium Glycinate - 150mg
  • Vitamin D3 (Cholecalciferol) - 2000 IU

Calcium citrate is more bioavailable than calcium carbonate and doesn't require stomach acid for absorption. Magnesium glycinate is calcium's metabolic partner. Vitamin D3 is the form consistently shown to raise serum levels effectively.

Quality Control Protocols

Every batch undergoes comprehensive third-party testing before it reaches our workshop. We test for identity, purity, and potency to ensure each capsule contains exactly what the label states.

Third-Party Verification Process

  • Raw Material Identity Testing - HPLC and FTIR spectroscopy confirm each ingredient is exactly what it claims to be
  • Heavy Metal Screening - Testing for lead, cadmium, mercury, and arsenic below FDA limits
  • Microbial Testing - Comprehensive pathogen screening including E. coli, Salmonella, and Staphylococcus
  • Potency Verification - Analytical testing confirms each ingredient meets label claim within 5% tolerance
  • Dissolution Testing - Capsule breakdown and ingredient release timing verification
  • Batch Documentation - Complete chain of custody documentation for every ingredient source

Certificate of Analysis

Every batch ships with a Certificate of Analysis from our third-party testing laboratory. This document shows the exact test results for identity, purity, potency, and safety parameters. No batch leaves our facility without passing all tests.

Manufacturing Standards

All products are manufactured in a GMP-certified facility following FDA guidelines for dietary supplements. Our manufacturing partner maintains ISO 9001 certification and undergoes annual third-party facility audits.

Stability Testing

Each formula undergoes accelerated stability testing to verify potency retention throughout the product's shelf life. We test at various temperature and humidity conditions to ensure ingredient integrity over time.

Source Verification

We maintain direct relationships with ingredient suppliers and verify their quality systems. Every raw material comes with a Certificate of Analysis, and we conduct on-site audits of key suppliers annually.
