Certificates of Analysis & Lab Tests: Understanding Heavy Metal Levels in Natural Shilajit Resin

Consumer safety is crucial when considering dietary supplements. Recent questions about the levels of lead and arsenic in Natural Shilajit Resin highlight the importance of understanding what these values mean in terms of safety standards and daily intake.

Heavy Metals in Dietary Supplements: What Are the Standards?

Heavy metals such as arsenic and lead are naturally found in the earth's crust and can, therefore, make their way into natural products, including dietary supplements. Recognizing this, regulatory authorities like the U.S. Food and Drug Administration (FDA) have set forth guidelines and action levels to ensure consumer safety.

For instance, the FDA has set an interim reference level (IRL) for lead in food products, incorporating a substantial safety margin to safeguard public health, particularly in sensitive groups such as children and pregnant women. Regarding arsenic, the FDA oversees both organic and inorganic forms in food, paying closer attention to the more harmful inorganic arsenic.

Comparing Levels: Natural Shilajit Resin vs. Everyday Foods

The lab analysis of our Natural Shilajit Resin shows 1.62 ppm of arsenic and 1.07 ppm of lead. These figures are not only compliant with regulatory standards but are also significantly lower than the maximum allowable limits for dietary supplements. For context, the European Commission Regulation (EU) 2021/1317 states a maximum level of 3.0 ppm for lead in food supplements, which is almost three times higher than the level found in our products.

To put this into perspective, let's consider common foods that are part of our daily diet. Certain fish, for example, can contain higher levels of mercury, while rice is known to absorb arsenic naturally from water and soil.

Lab Analysis: Ensuring Compliance with FDA Standards

Our recent lab testing, carried out by an independent, accredited laboratory, meticulously quantified the levels of various trace elements within our Shilajit resin. Here's how our findings compare with the FDA's safety guidelines:

  • Arsenic: At 1.62 ppm, our Shilajit resin's arsenic level is significantly lower than the FDA's action level of 10 ppb for apple juice. While the FDA has not established an action level for dietary supplements, we ensure our levels are kept well within the safe range for consumer health​ [ ... ] .
  • Cadmium: Our product contains cadmium at 0.120 ppm, which is below the permissible limit. The FDA's "Closer to Zero" initiative focuses on reducing cadmium exposure, particularly in food products consumed by children, and we adhere to these guidelines to ensure the protection of our consumers​ [ ... ] .
  • Lead: The detected lead level in our Shilajit resin is 1.07 ppm. Considering the FDA's IRLs for lead, which recommend a daily intake of 3 μg for children and 12.5 μg for adults, our product maintains levels that are considered safe when consumed in typical serving sizes​ [ ... ] .
  • Mercury: Our analysis shows no detectable mercury (0.00 ppm) in the Shilajit resin. This ensures safety against the FDA's guidelines, which aim to minimize mercury exposure, especially in products like seafood that are prone to higher mercury levels​ [ ... ] .

Understanding Heavy Metal Levels in Natural Shilajit Resin

Here are ten real-life examples of foods that can contain higher levels of heavy metals:

  1. Swordfish: Often contains mercury levels that can exceed 1.0 ppm, leading health organizations to recommend limiting consumption, especially for pregnant women and young children.
  2. Shark: Similar to swordfish, shark meat can contain high levels of mercury.
  3. Tuna: Certain types of tuna, especially bigeye and albacore, can accumulate significant amounts of mercury.
  4. Rice and Rice Products: Known to absorb arsenic from water and soil, which has led to the FDA evaluating and proposing limits for arsenic in rice cereal for infants.
  5. Spinach: This leafy green can accumulate lead and cadmium from the soil, with the levels varying based on environmental factors.
  6. Sweet Potatoes: Root vegetables, like sweet potatoes, can have higher levels of lead and cadmium because they grow directly in soil.
  7. Chocolate: Cocoa beans, from which chocolate is made, can contain lead and cadmium, originating from the soil where they are grown.
  8. Sunflower Seeds: Often contain cadmium, which they absorb from the soil.
  9. Tea Leaves: Tea leaves, particularly from older plants, can accumulate high levels of lead and arsenic from the environment.
  10. Leafy Greens: Other leafy greens, like lettuce and kale, can also take up heavy metals from the soil, though typically at lower levels than spinach.

It's important to understand that the presence of heavy metals in these foods does not necessarily make them unsafe to consume. Regulatory agencies establish safe consumption levels based on typical exposure rates and the presence of heavy metals within the context of a balanced diet. The examples provided are instances where, due to environmental factors and bioaccumulation, these foods can sometimes contain higher levels of heavy metals. However, this is highly dependent on the source and the conditions in which they were grown or caught.
