Heavy Metals Breakdown
We highly value honesty and truth at Lost Empire Herbs. These two qualities are something we try hard to propagate in our own lives and since this company is an extension of us, they permeate its edifice as well. Fundamental to that is complete transparency in lab testing and publishing those results.
One of the ways we have found for Lost Empire Herbs to embody these ideals is to be as transparent with it's operations as possible.
The main reason behind this is that the herbal supplement industry has a reputation for snake oil salesmen who promise much, make the sale and then run with the profit, leaving dejection and anger in their wake. The only way to dispel this enduring myth of herbalism is to PROVE that this is not our intention in the least and show that we really are here to help people live better lives.
One of the most asked questions companies like ours receive is about the Heavy Metal content of the herbs.
Many recent studies have shown a lot of brands to be cut with dangerous fillers or replaced with entirely different items then what is stated on the label. Many of these lower quality brands are full of metals that can potentially be dangerous to the health.
We wish to waylay the fears of our loyal customers. Since we consume these herbs as well it is fair to say we all want the same thing; clean, quality product.
With that in mind, here is the results of our testing for heavy metals for each herb we sell.
We also figured out the math and added the amount of heavy metals you could get from taking our maximum recommended dosage. Remember that just because you eat something doesn't mean you absorb everything from it but these numbers are a good place to start.
Testing is a continuing process as every batch of herbs is different in nutrients due to a variety of factors. Different levels of nutritions means different levels of heavy metals so as new tests come in we will update these to be as recent as possible with the product we are selling.
Finally, below is listed what is considered the safe heavy metal standards followed by government agencies and the American Herbal Products Association for reference.
We have also used the grading system of lowheavymetalsverified.org for the laboratory results (not the max dosage). The corresponding letter grade refers to the worst of these four minerals: arsenic, cadmium, lead, and mercury. It should be noted that all of their A grades are way more strict then most government agencies.

As we are doing this freely in the hope of garnering trust from our customers, we encourage you to be relentless in getting the rest of the industry to be more transparent in their operations. If this industry is to raise up to its potential of being a legitimate source of transformational health to people, we all must be diligent in regards to quality, source and manufacture of these products.
Note: sometimes the math just lines up and the amount given for max dosage equals the amounts found in testing. This has to do with amounts of grams consumed so if you see that both tables are exact, it is not a mistake.
