"Nutritional insurance" supplementation and corticosteroid toxicity.

Specialized "nutritional insurance" supplementation may reduce the risk of many important complications of long-term corticosteroid treatment. Supplementation with calcium, fluoride, activated vitamin D metabolites, and GTF, should help prevent osteoporosis. GTF, vitamin C, zinc and fluoride might help offset the inhibitory effect of corticosteroids on fibroblast and osteoblast function. Diabetic, hyperlipidemic and protein-losing effects might be compensated with supplementary GTF. Antioxidant nutrients could support humoral immunity and neutrophil function, while complementing the anti-inflammatory actions of corticosteroids. Supplementary magnesium could reduce the risk of nephrocalcinosis and nephrolithiasis.
