Possible Interaction: Nandrolone and Calcium Supplement

“After 1 year there was a significant increase in the BMC of the lumbar spine in the group receiving calcium plus nandrolone decanoate.”

“After 1 yr there was a significant increase in lumbar spine BMC in the group receiving calcium plus ND.”

“ Nandrolone decanoate statistically significantly increased the bone mineral content at the radius, reduced the endosteal bone loss at the metacarpals and statistically significantly reduced urinary calcium and hydroxyproline excretion.”

“However, when NPP was reduced to 0.225% and Ca to 0.75%, significant negative impacts on body weight, feed consumption, feed efficiency, and bone strength were observed.”

“Furthermore, nandrolone decanoate increases calcium balance and muscle mass, diminishes vertebral pain and increases the mobility of the spine.”

“The results are consistent with the concept that nandrolone exerts a significant positive effect on bone formation and that this results in a fall in the fasting plasma calcium level, and consequently calcium excretion.”

“Interaction between Ca and nPP on IP6 concentration was seen in Prov+Giz (P < 0.05).”

“Diets with a broader Ca : nPP ratio improved the digestibility of Ca but were deleterious to the digestibility of P. In this study, apparent digestibility of amino acids was broadly unaffected by dietary Ca and nPP concentrations.”

“Some authors suggested that nandrolone could cause the release of intracellular calcium and thereby explain the pro-arrhythmic effects observed in rats.”

“ Nandrolone decanoate treatment thus affects Ca 2 + uptake by the SR in a fibre-type dependent manner.”
