Introduction
Roynest Inc. is proud to announce a significant milestone in our ongoing commitment to product excellence and consumer safety. Our premium-grade matcha powder has successfully passed rigorous heavy metal screening in accordance with Canadian Testing Standards. This comprehensive evaluation tested for the presence of four primary heavy metals of concern—cadmium, arsenic, lead, and mercury—and confirmed that all levels were well below the acceptable limits established for food products in Canada.
This certification not only reaffirms the safety and purity of Roynets Matcha but also underscores our dedication to maintaining the highest standards of quality control, transparency, and scientific integrity in the natural products industry.
Understanding Heavy Metals and Why Testing Matters
Heavy metals are naturally occurring elements found throughout the environment—in soil, water, and air. While trace amounts can appear in a wide range of agricultural products, elevated levels of certain metals pose health concerns over time. The most commonly monitored heavy metals in food and beverage testing are cadmium, arsenic, lead, and mercury, each with distinct toxicological profiles:
-
Cadmium (Cd): Prolonged exposure can affect kidney function and bone density.
-
Arsenic (As): Chronic ingestion of inorganic arsenic is associated with various systemic effects, including skin lesions and cardiovascular concerns.
-
Lead (Pb): Known for its neurotoxic effects, especially in children, lead exposure can also impact cardiovascular and renal health.
-
Mercury (Hg): Often originating from environmental contamination, mercury can impair neurological and reproductive systems at high exposure levels.
Given that tea plants naturally absorb minerals and elements from the soil, testing for heavy metals is a critical quality assurance step in ensuring consumer safety—particularly for concentrated products like matcha, where the entire leaf is consumed.
Commitment to Canadian Testing Standards
Roynest Inc. adheres to Canadian Testing Standards for Food Safety, recognized globally for their stringent scientific methodology and regulatory compliance. These standards require precise analytical testing conducted through accredited laboratories, using validated methods such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
ICP-MS allows for the detection of trace heavy metal concentrations at parts-per-billion (ppb) levels, ensuring that even minute quantities are accurately quantified. By meeting and surpassing these benchmarks, Roynets demonstrates full compliance with Health Canada’s guidelines for heavy metal limits in food products—a vital assurance for consumers seeking trusted, health-conscious nutrition.
Results That Reflect Purity and Integrity
The recent certification confirms that Roynest Matcha Powder contains non-detectable or negligible levels of the four heavy metals tested—cadmium, arsenic, lead, and mercury. All results were well below the maximum allowable limits set forth by Canadian authorities.
This outcome is more than a regulatory requirement; it is a reflection of Roynets’ carefully controlled agricultural and manufacturing processes. Our matcha is cultivated in regions where soil composition and water quality are routinely monitored, ensuring the natural environment supports clean and sustainable growth. Each batch is subjected to comprehensive quality assurance protocols, including:
-
Soil and water testing prior to harvest.
-
Post-harvest batch analysis for contaminants and nutrient content.
-
Strict traceability from source to shipment.
Through these measures, Roynets maintains full control over the production chain, guaranteeing that every package of matcha meets the highest purity and safety standards available on the market.
The Health Significance of Certified Clean Matcha
Consumers choose matcha not only for its vibrant flavor and cultural heritage but also for its nutritional and functional benefits. Rich in antioxidants—particularly catechins such as EGCG—matcha supports metabolic health, cognitive function, and immune balance. However, these benefits can only be fully realized when the product is free from contaminants that may counteract its wellness potential.
By achieving certification under Canadian heavy metal testing protocols, Roynets provides customers with scientific assurance that their daily cup of matcha supports health rather than compromising it. This distinction is particularly important for:
-
Health-conscious individuals integrating matcha into daily wellness routines.
-
Clinicians and nutritionists recommending antioxidant-rich dietary interventions.
-
Retailers and distributors seeking to align with clean-label, evidence-based food brands.
This certification also strengthens confidence among international partners and regulatory bodies, supporting Roynest’ position as a global leader in premium matcha products.
Transparency and Traceability as Core Values
In an era when consumers demand accountability and openness from the brands they trust, Roynest is committed to full transparency. Certification results and supporting documentation are available upon request, offering complete visibility into our safety and testing processes.
We view testing not as a one-time requirement, but as an ongoing quality practice. Routine third-party testing ensures consistency from harvest to harvest, maintaining the integrity of the Roynest name. This continuous cycle of evaluation and verification upholds our central promise: to deliver matcha that embodies purity, safety, and scientific rigor.
Sustainability and Ethical Sourcing
The purity of Roynest Matcha begins long before testing—it starts at the source. Our agricultural partners employ sustainable farming practices that prioritize soil health, biodiversity, and responsible water use. Avoiding excessive use of chemical fertilizers and pesticides helps minimize environmental heavy metal accumulation over time.
By choosing sustainable cultivation and ethical sourcing, Roynest not only ensures a cleaner product but also contributes to global environmental stewardship—protecting both human health and the ecosystems that sustain it.
Looking Ahead: Continuous Improvement and Innovation
While certification marks a major achievement, Roynest views this milestone as a foundation for future advancement. We continue to invest in research partnerships, advanced analytical testing technologies, and international quality certifications to expand our commitment to product safety and scientific excellence.
Our goal is to remain at the forefront of nutritional science and food safety innovation—ensuring that every consumer experience with Roynets Matcha is not only enjoyable but also grounded in trust, transparency, and measurable quality.
Conclusion
Roynest Inc.’s certification for heavy metal safety under Canadian Testing Standards reinforces our longstanding dedication to quality, science, and consumer wellbeing. In an increasingly health-conscious world, this achievement stands as a symbol of trust—representing the harmony between natural tradition and modern safety science.
Every serving of Roynest Matcha embodies this principle: pure, tested, and certified—a reflection of our belief that true wellness begins with transparency and uncompromising standards.
