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.
