Yes, for urine protein, uACR ≥30 mg/g or >150 mg/day exceeds normal; persistent or ≥300 mg/g needs prompt medical review.

Most healthy adults tolerate up to about 2 g/kg/day of protein; no official UL exists, and people with kidney disease need lower medical guidance.

Daily fiber turns “too much” when symptoms start; many people hit limits above 45–70 grams without enough fluid and spacing.

Most healthy adults do well with 1–20 billion CFU per day; higher doses offer no clear added benefit and can raise side-effect risk.

With gummy vitamins, the safe limit is the labeled serving; extra chews can push nutrients past safe daily caps, especially for kids.

Excess vitamin B6 means doses near or above set upper limits; keep daily supplements at 10–25 mg or less unless a clinician advises otherwise.

In serum testing, vitamin B12 above 900–1,000 pg/mL is often flagged as high; repeats, context, and symptoms guide next steps.

For vitamin B12 intake, no formal upper limit exists; adults need little, and megadoses rarely add benefit without a medical reason.

Vitamin K2 has no official upper limit; healthy adults commonly tolerate up to 180 mcg/day, but blood thinners require clinician advice.

Excess vitamin D3 can raise calcium too high, leading to nausea, thirst, confusion, kidney strain, and heart rhythm problems.
