More than 20% of older adults may have marginal or frank vitamin B12 deficiency [Park, et.al. 2006], while folic acid is often deficient in children and reproductive aged females. Glutamine, arginine, fatty acids, and vitamin E provide additional benefits to immunocompromised persons or patients who suffer from various infections, while long-chain polyunsaturated n-3 fatty acids, vitamin E, vitamin C, selenium, and nucleotides can modulate immunity to fight infection [Field, et.al. 2002]. In order to produce energy, the use of glucose by nervous tissue requires vitamin B1; this vitamin modulates cognitive performance, especially in the elderly. Vitamin B9 preserves brain during its development and memory during ageing. Vitamin B6 is likely to benefit in treating premenstrual depression. Vitamins B6 and B12, among others, are directly involved in the synthesis of some neurotransmitters [Bourre, JM. 2006]. Thus, three formulations added to L. rhamnosus GR-2 supplemented yogurt, will be tested at the Brescia College Tasting Centre where volunteers will score the products for taste and texture [Hekmat, S. & Reid, G. 2006]
