  1. No significant differences in the lysine and control groups before adding lysine tested using independent sample t-test
  2. The group reveals the expected enhancement in baseline value of the lysine group nutrients on adding 1000 mg of lysine which is corresponding to the quantity of supplement supplied
  3. Percent at risk of protein deficiency, based on a requirement of protein of 0.66 g/kg intended for adults (WHO, 2007)
  4. Adult amino acid requirements: 30 mg/kg/day lysine, 15 mg/kg/day sulfur amino acids, 15 mg/kg/day threonine, 4 mg/kg/day tryptophan (WHO, 2007)
  5. Difference from placebo group, p < 0.001
