Blue Glass 4 oz Bottle for Physica Green Light Supplement: Positive for trace Cadmium (15 ppm) and Antimony (25 ppm).

When tested with an XRF instrument the glass bottle pictured here had the following readings.

Reading One: Side of Blue Glass Bottle (tested on a section without the label). Three Minute Reading.

• Barium (Ba): 2,531 +/- 147 ppm
• Chromium (Cr): 682 +/- 74 ppm
• Tin (Sn): 39 +/- 22 ppm
• Copper (Cu): 38 +/- 12 ppm
• Nickel (Ni): 39 +/- 12 ppm
• Iron (Fe): 568 +/- 37 ppm
• Bismuth (Bi): 10 +/- 4 ppm

Second reading of same component also included:

• Cadmium (Cd): 15 +/- 4 ppm
• Antimony (Sb): 25 +/- 10 ppm

Reading Two: Rounded Edge of Bottle Near Top.
Two Minute Reading.

Cadmium & Antimony levels were confirmed with multiple readings. These levels are considered low / trace (a contaminant of the glass and not an ingredient added intentionally.) As with the reading set above, levels this low may appear in some readings and not in other readings.

• Cadmium (Cd): 15 +/- 5 ppm
• Antimony (Sb): 27 +/- 11 ppm
• Tin (Sn): 24 +/- 9 ppm
• Iron (Fe): 993 +/- 106 ppm
• Vanadium (V): 950 +/- 46 ppm
• Titanium (Ti): 179 +/- 27 ppm
• Indium (In): 20 +/- 6 ppm
• Palladium (Pd): 7 +/- 3 ppm
• Silver (Ag): 8 +/- 3 ppm
• Cobalt (Co): 839 +/- 74 ppm

Reading Three: Clear Glass of Dropper.
Tested for at least one minute (60 seconds).

• Barium (Ba): 5,371 +/- 198 ppm
• Iron (Fe): 356 +/- 141 ppm
• Vanadium (V): 2,943 +/- 145 ppm
• Titanium (Ti): 5.970 +/- 282 ppm

Reading Four: Black Hard Plastic Collar of Dropper.
Tested for at least one minute (60 seconds).

• Barium (Ba): 370 +/- 117 ppm
• Bromine (Br): 14 +/- 3 ppm
• Zinc (Zn): 1,104 +/- 27 ppm
• Iron (Fe): 105 +/- 22 ppm

Reading Five: Black Rubber of Dropper.
Tested for at least one minute (60 seconds).

• Barium (Ba): 293 +/- 60 ppm
• Selenium (Se): 25 +/- 14 ppm
• Bromine (Br): 22 +/- 5 ppm
• Zinc (Zn): 18,400 +/- 100 ppm
• Nickel (Ni): 7 +/- 4 ppm
• Iron (Fe): 417 +/- 17 ppm
• Bismuth (Bi): 9 +/- 4 ppm
• Titanium (Ti): 522 +/- 108 ppm

This level of Cadmium is considered safe by all standards. To my knowledge no one has done any studies to determine if this level of Cadmium found in a glass bottle may (or may not) leach into the contents.

Regardless of whether or not it is a leaching concern, as Cadmium is a known carcinogen I personally would like to see supplement companies making an effort to ensure the bottles that contain their products are free of toxicants like Lead, Antimony and Cadmium.

As always, please let me know if you have any questions.
