Post-supplementation B12 Testing should be done to ensure sufficiency
A small RCT (n=21) found that inhaled glutathione (600 mg twice daily for 3 months) modestly improved some pulmonary function parameters (Griese et al., Am J Respir Crit Care Med, 2004) [47]
Results showed that both the inulin and placebo groups experienced reductions in energy intake, BMI, systolic blood pressure, and -GT levels
Most people get enough vitamin B12 in their diet, but a deficiency may occur in certain health conditions (e.g., poornutrition,stomach/intestinal problems, infection,cancer)
