Lysine Requirements of Elderly Female Subjects 65-75 Years Old.
The lysine requirement of elderly female subjects 65-75 years old will be 40-45 mg/kg/day.
Lysine Requirement in Elderly Female Subjects
Dietary Supplement: Lysine intake provided as a milkshake
|Study Design:||Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Health Services Research
- change in oxidation of phenylalanine in response to increasing lysine intake [ Time Frame: 8 hours ] [ Designated as safety issue: No ]F13CO2
- phenylalanine oxidations determined from urinary phenylalanine enrichments [ Time Frame: 8 hrs ] [ Designated as safety issue: No ]phenylalanine oxidation (phe OX)
|Study Start Date:||September 2012|
|Study Completion Date:||September 2013|
|Primary Completion Date:||September 2013 (Final data collection date for primary outcome measure)|
|Experimental: lysine intake at different levels of intake||Dietary Supplement: Lysine intake provided as a milkshake|
Currently there are no studies on lysine requirement in the elderly.
The goal of this study therefore is to measure the lysine requirement of female elderly subjects 65-75 years using the IAAO technique.
