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)
“I have more in common with a Mexican man than with a white woman.... This opinion ... chagrins women who sincerely believe our female physiology unequivocally binds all women throughout the world, despite the compounded social prejudices that daily affect us all in different ways. Although women everywhere experience life differently from men everywhere, white women are members of a race that has proclaimed itself globally superior for hundreds of years.”
—Ana Castillo (b. 1953)
“We live in what virtually amounts to a museum—which does not happen to a lot of people.”
—Philip (b. 1921)
