You will also find in the study analysis of what compounds the molybdenum forms as it dissolves.
Also, who knew they were supposed to be getting molybdenum every day? Somehow I feel a bit more cyborgy now, like maybe there is a tiny gear in me somewhere that needs to be greased.
When a buddy got a damaged tooth replaced with an implant, he showed me medical scans of the titanium rod in-situ with the surrounding bone highlighted as growing into the rod as if they had an affinity for one another. It was part of a document explaining the safety and why titanium was chosen, how the body doesn't reject the material as foreign etc.
Studies on rats show a median lethal dose (LD50) as low as 180 mg/kg for some Mo compounds.
Although human toxicity data is unavailable, animal studies have shown that chronic ingestion of more than 10 mg/day of molybdenum can cause diarrhea, growth retardation, infertility, low birth weight, and gout; it can also affect the lungs, kidneys, and liver
Also, 10mg/day in which animals? I would guess animals that are a lot smaller than humans, possibly even mice (weight: less than 1/1000 of that of a human)
