Amino Acid Medical Foods Provide a High Dietary Acid Load and Increase Urinary Excretion of Renal Net Acid, Calcium, and Magnesium Compared with Glycomacropeptide Medical Foods in Phenylketonuria

Figure 3

Renal net acid excretion (a), urinary calcium excretion (b), urinary magnesium excretion (c), and urinary sulfate excretion (d), based on 24-hr urine collections in participants with PKU who consumed AA-MF or GMP-MF, n = 8. Statistical significance reflects significant treatment effects, as shown in Figure 2. Results show increases among all 8 participants in urinary excretion of renal net acid, calcium, and sulfate and in 7 of 8 participants in urinary excretion of magnesium with AA-MF compared to GMP-MF. AA-MF, amino acid medical foods; GMP-MF, glycomacropeptide medical foods.
