Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk.

Supplements may only contain dosages of 21 mg/day. [45] European Food Safety Authority: 12 mg/day [25] Ministry of Health, Labour and Welfare (厚生労働省, Kōsei-rōdō-shō) Japan 40–60 mg/day The adult UL was set at 40–45 mg/day for women and 50–60 mg/day for men, with the lower values in those ranges for adults over 70 years of age
AT = Averaged time, in days. This term specifies the length of time over which the average dose is calculated. For quantifying cancer risk a "lifetime" of 70 years is used (i.e, 70 years times 365 days/year). SF = Cancer slope factor (mg/kg-day) −1 ADAF = Age-dependent adjustment factor for age bin "i" (unitless)
The recommended adequate intake of sodium is 1,500 milligrams (3.9 g salt) per day, and people over 50 need even less." [13] The Daily Value for potassium, 4,700 mg per day, was based on a study of men who were given 14.6 g of sodium chloride per day and treated with potassium supplements until the frequency of salt sensitivity was reduced to 20%.
Trough estradiol levels and MADRS Tooltip Montgomery–Åsberg Depression Rating Scale scores with 1 mg sublingual micronized estradiol 3 to 8 times per day (3 to 8 mg/day total; mean 4.8 mg/day total) in women with postpartum depression. [8] Blood was drawn specifically in the mornings before the first dose of sublingual estradiol for the day. [8]
Upon analysis, scientists found that participants who stayed on standard statin treatment for their lifetime increased their quality-adjusted life years by 0.24-0.70, and those on higher-intensity ...
In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
Drugs come with a recommended dose in milligrams or micrograms per kilogram of body weight, and that is used in conjunction with the patient's age and body weight to determine a safe dose. In single-dose scenarios, the patient's body weight and the drug's recommended dose per kilogram are used to determine a safe one-time dose.
