Vegetarians and vegans: Since most foods that contain B12 naturally are animal products like meat, eggs and dairy, vegetarians and vegans are at greater risk of developing a B12 deficiency
Organ transplant recipients on immunosuppressants like cyclosporine
AMPK also downregulates SLC7A11 activity, inhibits system Xc, and decreases cystine transport and GSH levels, ultimately leading to ROS accumulation and the onset of ferroptosis [104, 106]

Notably, two such trials with low dose NAC, 600 mg/day over 3 years demonstrated some efficacy in inhaled corticosteroid (ICS)-nave patients only ( High-dose NAC (1,200 mg/day) showed superior outcomes, improving lung volumes [Forced Vital Capacity (FVC), Residual Volume/ Total Lung Capacity (RV/TLC), Inspiratory Capacity (IC)] and exercise tolerance( 2575% ), reactance at 6 Hz, and resonant frequency over 1 year, while these declined with placebo ( The PANTHEON trial, a large double-blind RCT in GOLD defined COPD patients with severe airflow obstruction and a history of 2 COPD exacerbations in the previous year, found that NAC 600 mg BID reduced exacerbation rates in NAC group (497 acute exacerbations in 482 patients, 1.16 AcEx/pt/yr) versus placebo (641 acute exacerbations in 482 patients, 1.49 AcEx/Pt/yr), p 1 log 10 ) compared to untreated controls (67)
