We believe that when using natural tonics, consistency and quality control is the top priority.
Our most important investment continues to be in quality control, assurance, batch testing and analysis.
In addition to rigorous quality control checks during manufacturing, we conduct post-production testing internally and also send finished batches of capsule and liquid tonic to external labs to test for authenticity, composition, toxicity, heavy metals, microbial and other contaminants.
All natural Phellinus linteus and Phellinus igniarius extracts found inside Amazing Grace products have passed LD50 acute oral toxicity testing: this certifies they are safe for human consumption up to the daily limit of 15,000mg per kg of bodyweight.
We also store a sample of every batch for the duration of its circulation, as well as samples of the raw Phellinus that was harvested.
Our commitment to quality assurance and best industry practices allows us all to enjoy the timeless natural wonders of Phellinus linteus and Phellinus igniarius with scientific precision and also peace of mind.
