Recommended Daily Amounts
Estimating the daily requirement for the indispensable amino acids has proven to be difficult; these numbers have undergone considerable revision over the last 20 years. The following table lists the WHO recommended daily amounts currently in use for essential amino acids in adult humans, together with their standard one-letter abbreviations.
| Amino acid(s) | mg per kg body weight | mg per 70 kg | mg per 100 kg |
|---|---|---|---|
| H Histidine | 10 | 700 | 1000 |
| I Isoleucine | 20 | 1400 | 2000 |
| L Leucine | 39 | 2730 | 3900 |
| K Lysine | 30 | 2100 | 3000 |
| M Methionine
+ C Cysteine |
10.4 + 4.1 (15 total) | 1050 | 1500 |
| F Phenylalanine
+ Y Tyrosine |
25 (total) | 1750 | 2500 |
| T Threonine | 15 | 1050 | 1500 |
| W Tryptophan | 4 | 280 | 400 |
| V Valine | 26 | 1820 | 2600 |
The recommended daily intakes for children aged three years and older is 10% to 20% higher than adult levels and those for infants can be as much as 150% higher in the first year of life.

Famous quotes containing the words recommended, daily and/or amounts:
“Goldsmith tells us, that when lovely woman stoops to folly, she has nothing to do but to die; and when she stoops to be disagreeable, it is equally to be recommended as a clearer of ill-fame.”
—Jane Austen (1775–1817)
“Post-modernism has cut off the present from all futures. The daily media add to this by cutting off the past. Which means that critical opinion is often orphaned in the present.”
—John Berger (b. 1926)
“She isn’t harassed. She’s busy, and it’s glamorous to be busy. Indeed, the image of the on- the-go working mother is very like the glamorous image of the busy top executive. The scarcity of the working mother’s time seems like the scarcity of the top executive’s time.... The analogy between the busy working mother and the busy top executive obscures the wage gap between them at work, and their different amounts of backstage support at home.”
—Arlie Hochschild (20th century)
