Manganese

i dont think manganese should be included. its very prevalent in the diet and higher intakes have been linked to disease.

Not so fast..only as an occupational hazard is it toxic and unless you have liver failure. That's it. Same can be said of other minerals.

dietary manganese is fairly abundant, also:

A study of older adults in Greece found a high prevalence of neurological symptoms in those exposed to water manganese levels of 1.8-2.3 mg/liter (29), whereas a study in Germany found no evidence of increased neurological symptoms in people drinking water with manganese levels ranging from 0.3-2.2 mg/liter compared to those drinking water containing less than 0.05 mg/liter (30). Manganese in drinking water may be more bioavailable than manganese in food. However, none of the studies measured dietary manganese, so total manganese intake in these cases is unknown. In the U.S., the EPA recommends 0.05 mg/liter as the maximum allowable manganese concentration in drinking water (31).

A single case of manganese toxicity was reported in a person who took large amounts of mineral supplements for years (32), while another case was reported as a result of a person taking a Chinese herbal supplement (25). Manganese toxicity resulting from foods alone has not been reported in humans, even though certain vegetarian diets could provide up to 20 mg/day of manganese (4, 32).

My diet provides 7.9mg. I'm not sure how much of that is ACTUALLY GOING TO BE BIOAVAILABLE, but if you do put it in, keep it low. Something like 2mg would suffice, as an AAC of course. If that's the case, I'm gonna go with ... ehh... a dubious 'yes' that I would not mind if you ignored.

As a note, you excrete 4mg per day.

Yes. (manganese bis-glycinate chelate 10 mg every other day, skipping weekends)

Agree. You get a lot in green tee (1mg/cup). Not to mention that some vegetarians already have intakes above the UL.
