Importantly, they use a definition of kilograms of fat free mass whereas others have used body weight
Here's the catch though
Across multiple drug classes, common patterns emerge: Corticosteroids accelerate protein breakdown and deplete calcium, vitamin D, magnesium, zinc, and vitamin Cnutrients required for bone strength, collagen synthesis, and immune repair Acetaminophen consumes glutathione, increasing oxidative stress and impairing cellular recovery NSAIDs interfere with iron, folate, and vitamin C absorption while disrupting prostaglandin-driven tissue healing Opioids suppress endocrine and immune signaling necessary for regeneration Individually, these effects may appear modest
L-glutamine supports the health of the digestive tract, while glutathione provides systemic antioxidant support and liver protection
