Strontium

Strontium/Nutrient Depletion:

  • AlginAlgin: According to human research and secondary sources, algin or alginate may bind to strontium and reduce its absorption from the GI tract and thereby lead to strontium toxicity (65).
  • AntacidsAntacids: According to the manufacturer, strontium ranelate should be taken two hours before or after antacids, as these agents may decrease strontium absorption.
  • CalciumCalcium: According to human research, calcium may reduce the intestinal absorption of strontium by 60-70%, possibly due to competition at binding sites (41). Strontium has also been found replace calcium and inhibit calcium absorption. Experts recommend taking strontium two hours before or after taking calcium.
  • CorticosteroidsCorticosteroids: In human research, strontium absorption was reduced (approximately 12%) by oral administration of beclomethasone dipropionate (26).
  • Dairy productsDairy products: According to human research, calcium-containing foods may reduce the intestinal absorption of strontium (41). In human research, strontium bioavailability was not significantly affected by lactose (28).
  • LaminariaLaminaria: Laminaria contains alginate. According to secondary sources, alginate may bind to strontium and reduce its absorption from the GI tract and thereby lead to strontium toxicity.
  • Seaweed, kelp, bladderwrackSeaweed, kelp, bladderwrack: Bladderwrack or kelp contains alginate. According to secondary sources, alginate may bind to strontium and reduce its absorption from the GI tract and thereby lead to strontium toxicity.
