Shark cartilage



Interactions

Shark cartilage/Drug Interactions:
  • AnalgesicsAnalgesics: Based on animal studies, shark cartilage has been shown to inhibit nitric oxide synthesis (47; 48).
  • AnestheticsAnesthetics: Based on animal studies, shark cartilage has been shown to inhibit nitric oxide synthesis (47; 48).
  • Antiangiogenic drugsAntiangiogenic drugs: Based on study, patients in treatment protocols involving other antiangiogenic agents should avoid shark cartilage, due to theoretical additive or synergistic activity. Examples include Ag3340, Bay12-9566, Leflunomide, Marimastat, Anti-VEGF antibody, Carboxyaminotriazole, CGS 27023A, AGM-1470, SU5416, Vitaxin, EMD 121974, Interleukin-12, and CM 101 (45).
  • Antiarthritic agentsAntiarthritic agents: In vitro and animal research shows that shark cartilage possesses anti-inflammatory properties (13; 14; 15; 49) and may improve affected joints (50).
  • Antidiabetic agentsAntidiabetic agents: In a phase I/II study using shark cartilage, a patient with type 2 diabetes mellitus and renal carcinoma was noted to develop hypoglycemia (25).
  • Anti inflammatory agentsAnti inflammatory agents: In vitro and animal research has reported that shark cartilage possesses anti-inflammatory properties (31; 13; 14; 15). In animals, shark cartilage was less effective as an anti-inflammatory agent than nitrones (51).
  • CisplatinCisplatin: Based on animal study, shark cartilage may possess antitumor effects (52).
  • Diuretics, thiazideDiuretics, thiazide: Shark cartilage products contain calcium (up to 25%) (28).
  • Gastrointestinal agents, miscellaneousGastrointestinal agents, miscellaneous: Based on human study, shark cartilage may cause gastrointestinal distress (nausea, vomiting, constipation, dyspepsia) (32; 28; 41; 42).
  • Interferons (? and ?)Interferons (? and ?): Based on study, both interferon ? and ? possess antiangiogenic properties and may act synergistically with shark cartilage to inhibit blood vessel growth, slow wound healing, reduce inflammation, or cause birth defects (45).
  • ThalidomideThalidomide: Based on study, thalidomide may act synergistically with shark cartilage to inhibit blood vessel growth, slow wound healing, reduce inflammation, or cause birth defects (53; 45).

Shark cartilage/Herb/Supplement Interactions:
  • AnalgesicsAnalgesics: Based on animal studies, shark cartilage has been shown to inhibit nitric oxide synthesis (47; 48).
  • AnestheticsAnesthetics: Based on animal studies, shark cartilage has been shown to inhibit nitric oxide synthesis (47; 48).
  • Antiangiogenic herbs and supplementsAntiangiogenic herbs and supplements: Based on study, patients in treatment protocols involving other antiangiogenic herbs and supplements should avoid shark cartilage due to theoretical additive or synergistic activity (45).
  • Antiarthritic herbs and supplementsAntiarthritic herbs and supplements: In vitro and animal research shows that shark cartilage possesses anti-inflammatory properties (13; 14; 15; 49) and may improve affected joints (50).
  • Anti inflammatory herbs and supplementsAnti inflammatory herbs and supplements: In vitro and animal research has reported that shark cartilage possesses anti-inflammatory properties (31; 13; 14; 15). In animals, shark cartilage was less effective as an anti-inflammatory agent than nitrones (51).
  • AntineoplasticsAntineoplastics: Based on animal study, shark cartilage may possess antitumor effects (52).
  • AntioxidantsAntioxidants: Ongoing in vitro research has reported that shark cartilage acts as a scavenger for reactive oxygen species (54; 55).
  • Calcium supplementsCalcium supplements: Shark cartilage products contain calcium (up to 25%) (28).
  • Chondroitin sulfateChondroitin sulfate: Chondroitin, a popular therapy for osteoarthritis, is a constituent of shark cartilage.
  • DiureticsDiuretics: Shark cartilage products contain calcium (up to 25%) (28).
  • Gastrointestinal herbs and supplementsGastrointestinal herbs and supplements: Based on human study, shark cartilage may cause gastrointestinal distress (nausea, vomiting, constipation, dyspepsia) (32; 28; 41; 42).
  • Glucosamine sulfateGlucosamine sulfate: Glucosamine, a popular therapy for osteoarthritis, is a constituent of shark cartilage.
  • HypoglycemicsHypoglycemics: In a phase I/II study using shark cartilage, a patient with type 2 diabetes mellitus and renal carcinoma was noted to develop hypoglycemia (25).
  • MineralsMinerals: Trace elements, such as iron, zinc, selenium, copper, manganese, molybdenum, titanium, and strontium, are found in high levels in shark cartilage.

Shark cartilage/Food Interactions:
  • Acidic fruit juices (apple, grape, orange, tomato, cranberry)Acidic fruit juices (apple, grape, orange, tomato, cranberry): Acidic fruit juices may reduce the absorption of shark cartilage (34; 31).

Shark cartilage/Lab interactions:
  • Calcium levelsCalcium levels: Shark cartilage products contain calcium (up to 25%) (28).
  • Keratan sulfateKeratan sulfate: Keratan is a protein measured in basic science research and experimentally as a marker of cartilage metabolism. A protein in shark cartilage reacts with the same antibodies as the keratan sulfate ELISA assay, which may lead to erroneous results (56).
  • Troponin-ITroponin-I: In theory, the troponin-I in shark cartilage may cause a false-positive result in human serum troponin-I assays, a test commonly used to evaluate cardiac ischemia (46). It is unclear, however, if the troponin-I is digested by proteolytic enzymes prior to absorption.
