Daily How Much

Metoprolol isn’t approved for anxiety; any dose must be prescribed for you, often as a low, event-based option when a clinician sees fit.

Most adults should not exceed 400 mg of metoprolol succinate or 450 mg of metoprolol tartrate in 24 hours.

Most adults start metformin at 500 mg with food, increasing by 500 mg each week toward 1,500–2,000 mg/day if tolerated for PCOS care.

Metformin dosing for type 2 diabetes starts low at 500 mg daily and increases stepwise toward 1,500–2,000 mg only if tolerated and prescribed.

Metformin typically lowers A1C by about 1% and fasting glucose by 20–60 mg/dL, depending on dose and starting levels.

Daily metformin safety depends on form: up to 2,550 mg for standard tablets, up to 2,000 mg for extended-release when kidney function is normal.

For metformin extended-release, the typical ceiling is 2,000 mg daily, raised in 500-mg steps with food under clinician guidance.

In milk chocolate, methylxanthines total about 145 mg per 100 g—about 125 mg theobromine and ~20 mg caffeine.

Daily methylprednisolone needs vary by condition: common oral ranges are 4–48 mg, with higher short courses set by a specialist plan.

Most adults need 2.4 mcg/day of vitamin B12; supplements often range 50–1,000 mcg based on diet, labs, and cause—ask your doctor for a plan.
