GENDER SPECIFIC SYNTHETIC NUTRITIONAL COMPOSITIONS AND NUTRITIONAL SYSTEMS COMPRISING THEM
Gender specific synthetic nutritional compositions comprising glycine in concentrations reflecting those found in human milk produced by mothers of infants of the corresponding gender at the corresponding stage of lactation, and nutritional systems comprising them.
1 . A Gender specific synthetic nutritional composition tailored for an infant comprising glycine in a concentration reflecting the concentration found in human milk produced for an infant of the same gender at the corresponding lactation stage.
2 . A gender specific synthetic nutritional composition according to claim 1 wherein, the composition is tailored for an infant of an age selected from the group consisting of up to 1 month of age, 1 to 2 months of age, and 2 months of age or older, and wherein if the concentration of glycine is tailored to a male infant of up to 1 month of age it is within the range of 18 to 157 mg/100 mL and, if the concentration of glycine is tailored to a female infant of up to 1 month of age it is within the range of 16 to 152 mg/100 mL; if the concentration of glycine is tailored to a male infant of 1 to 2 months of age it is within the range of 15 to 45 mg/100 mL and, if the concentration of glycine is tailored to a female infant of 1 to 2 months of age it is within the range of 17 to 54 mg/100 mL; and if the concentration of glycine is tailored to a male infant of 2 months of age or older it is within the range of 8 to 77 mg/100 mL and, if the concentration of glycine is tailored to a female infant of 2 months of age or older it is within the range of 13 to 42 mg/100 mL.
3 . A gender specific synthetic nutritional composition according to claim 1 wherein, the gender specific synthetic nutritional composition is selected from the group consisting of: infant formula, and a composition for infants that is intended to be added to or diluted with human milk.

5 . A nutritional system comprising a gender specific synthetic nutritional composition tailored for an infant comprising glycine in a concentration reflecting the concentration found in human milk produced for an infant of the same gender at the corresponding lactation stage.
6 . A nutritional system according to claim 5 comprising a gender specific synthetic nutritional composition for a male infant and, one gender specific nutritional composition for a female infant wherein the male and female gender specific synthetic nutritional compositions are for infants of 1 to 2 months of age, and wherein the concentration of glycine in the gender specific synthetic nutritional composition for a female infant is higher than in the gender specific synthetic nutritional composition for a male infant.
7 . A nutritional system according to claim 5 comprising a gender specific synthetic nutritional composition for a male infant and, one gender specific nutritional composition for a female infant wherein the male and female gender specific synthetic nutritional compositions are for infants of the same age and selected from the group consisting of up to 1 month of age and older than 2 months of age, and wherein the concentration of glycine in said gender specific synthetic nutritional composition for a male infant is higher than in said gender specific synthetic nutritional composition for a female infant.
8 . A nutritional system according to claim 5 wherein if the gender specific synthetic nutritional compositions are for infants of up to 1 month of age the male gender specific synthetic nutritional composition comprises 2 to 139 mg/100 mL more glycine than the female gender specific synthetic nutritional composition; if the gender specific synthetic nutritional compositions are for infants of 1 to 2 months of age the female gender specific synthetic nutritional composition comprises 1 to 27 mg/100 mL more glycine than the male gender specific synthetic nutritional composition; and if the gender specific synthetic nutritional compositions are for infants of 2 months of age or older the male gender specific synthetic nutritional composition comprises 0.01 to 62 mg/100 mL more glycine than the female gender specific synthetic nutritional composition.
9 . A nutritional system according to claim 5 comprising a gender neutral synthetic nutritional composition and/or gender specific synthetic nutritional compositions for infants wherein, the concentration of glycine in the gender specific synthetic nutritional compositions does not differ by gender for infants of the same age.
10 . A nutritional system according to claim 9 wherein the nutritional system only comprises a gender specific synthetic nutritional composition for an infant of 1 to 2 months of age, and wherein the nutritional system comprises for infants up to 1 month of age and/or 2 months of age or older, a gender neutral synthetic nutritional composition and/or gender specific synthetic nutritional compositions wherein the concentration of glycine does not differ by gender.

13 . A method for providing an optimum amount of glycine to an infant and preventing or mitigating sub optimal growth and development comprising:
preparing a gender specific synthetic nutritional composition tailored for an infant comprising glycine in a concentration reflecting the concentration found in human milk produced for an infant of the same gender at the corresponding lactation stage; and
feeding a gender specific synthetic nutritional composition to an infant.
