Science-Based Safety Profile
We are committed to transparency. This page summarizes the current scientific literature regarding the oral safety of our colloidal gold, platinum, iridium, copper, zinc, and silver supplements at typical supplement concentrations (10–20 ppm). These products are sold as dietary supplements and have not been evaluated by the FDA for safety or efficacy.
Gold Nanoparticles (colloidal gold at 10–20 ppm oral doses):
No conclusive scientific proof establishes that ingested gold nanoparticles at typical 10–20 ppm supplement levels (extremely low daily exposure, often ~0.05–0.2 mg) are harmful short-term or long-term to humans; it is not an established fact of toxicity. Oral bioavailability is minimal, and multiple animal studies (including 14-day and 90-day repeated dosing) at far higher doses show no severe toxicity, no major organ damage, and only minor or non-adverse changes in some parameters. While some high-dose or in vitro studies report variable effects, these do not translate to harm at dilute oral supplement levels. Long-term human data is limited, as with most supplements.
Platinum Nanoparticles (colloidal platinum at 10 ppm oral doses):
No conclusive scientific proof establishes that ingested platinum nanoparticles at typical 10 ppm supplement levels (extremely low daily exposure, often <<0.1 mg) are harmful short-term or long-term to humans; it is not an established fact of toxicity. Oral bioavailability is low, and in vitro intestinal models often show non-cytotoxicity with potential antioxidant effects. Animal oral studies at much higher doses yield mixed results (some inflammation/oxidative stress noted), but many assessments highlight good biocompatibility with no or limited adverse effects. Intravenous routes show more potential issues, but these do not apply to low-dose oral use. No human evidence of harm exists at supplement-relevant exposures.
Iridium Nanoparticles (colloidal iridium at 10 ppm):
There is virtually no direct scientific proof or dedicated studies on short-term or long-term harm from ingested iridium nanoparticles as supplements at 10 ppm levels; it is not an established fact that they are harmful. Iridium nanomaterials are minimally studied, with available data indicating generally low toxicity and inert behavior. No specific oral toxicity studies on colloidal iridium at supplement doses exist. No unique risks are indicated at these trace levels.
Copper Nanoparticles (colloidal copper at 10–20 ppm oral doses):
No conclusive proof establishes that ingested copper nanoparticles at typical 10–20 ppm supplement levels (extremely low daily exposure) are harmful short-term or long-term when used as directed; however, it is not an established fact of complete safety, and higher doses show greater potential for toxicity than the precious metals above. Copper is an essential nutrient, but nano forms can exhibit higher reactivity; some animal oral studies at much higher doses report liver/kidney effects, oxidative stress, or intestinal changes, while others (including certain coated or lower-dose models) indicate low cytotoxicity and biocompatibility. Oral absorption is partial and dose-dependent, with most material excreted. At dilute supplement levels, risks appear limited, but excessive intake could contribute to copper overload. Long-term human data specific to colloidal nano copper is limited.
Zinc Nanoparticles (colloidal zinc / zinc oxide at 10–20 ppm oral doses):
No conclusive proof establishes that ingested zinc nanoparticles at typical 10–20 ppm supplement levels (extremely low daily exposure) are harmful short-term or long-term when used as directed; it is not an established fact of toxicity at these trace amounts. Zinc is an essential nutrient with well-characterized safe upper limits (typically 25–40 mg/day elemental zinc). Nano zinc oxide shows high dissolution in gastric acid, behaving largely like ionic zinc; acute oral toxicity is low (>2000 mg/kg in rats), but repeated high-dose animal studies report mild effects on blood parameters, pancreas, or gut microbiota at levels far above supplements. At dilute colloidal concentrations, bioavailability and risks align more closely with conventional zinc forms. Long-term human data for nano forms is limited, and excessive zinc can interfere with copper/iron absorption.
Silver Nanoparticles (colloidal silver at 10–20 ppm oral doses):
Scientific evidence show low-dose use has few documented issues, but it is not an established fact that 10–20 ppm supplements are entirely harmless with prolonged use. Oral absorption is low (0.4–18%), yet silver can deposit in tissues (skin, organs). Reviews and regulatory bodies (e.g., FDA, NCCIH) advise against routine oral consumption of colloidal silver. Animal studies show dose-dependent effects including weight changes or immune alterations at higher exposures. At typical dilute supplement levels, acute toxicity is low, but chronic accumulation remains a concern—product purity and limited duration of use are important.
