Bismuth

Optimal result: 0 – 2.28 ug/g creat

Nephropathy (= deterioration of kidney function), GI complaints, encephalopathy (= disease of the brain that alters brain function or structure), difficulty walking/standing, memory deterioration, behavioral change, insomnia, muscle cramping. Decreased appetite, weakness, gingivitis (= a common and mild form of gum disease), dermatitis (= common skin irritation), and diarrhea have also been seen clinically with chronic bismuth toxicity.

Used in alloys, electronics, batteries, crystal ware, cosmetics, flame retardants,and in antimicrobial therapy (H. pylori), antiseptic dressings, paraffin paste. Bismuth medical therapies exhibit high therapeutic effects and little side effects, though over-dosage can cause toxicity.

Very limited absorption in the GI tract. When absorbed, it binds mainly to transferrin and lactoferrin, interacts with enzymes due to a high affinity to cysteine residues, blocking the active site. Can accumulate in the kidney, lung, spleen, liver, brain, and muscles, while being eliminated in urine and feces via bile and intestinal secretions.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
