Shark Cartilage
Updated Oct. 13th, 2017
Shark cartilage is a powder (usually sold in capsule form) made of (as you would expect!) dried shark cartilage.
Past Research
Shark cartilage was once thought to be the new cancer cure, as some studies have shown it to prevent the growth of new blood vessels, angiogenesis, a process by which certain types of cancer are spread.
Not all studies have shown shark cartilage to have this effect, and certainly it provides no help to individuals whose cancers are not determined by angiogenesis. It seems more research is necessary before statements in terms of cancer therapy can be made.
Arthritis Treatment
Today, the majority of shark cartilage supplements are aimed at arthritis and joint health. Shark cartilage is made up of, in large part, calcium, obviously an important component of bone health. Another major constituent of shark cartilage are what are known as mucopolysaccharides (or Glycosaminoglycans) such as chondroitin sulfate. chondroitin sulfate is major player in maintaining the structural foundation of the body – specifically responsible for the 'resistance to compression' properties of cartilage.
How does shark cartilage work?
Cartilage is the shock absorber of the body, cushioning and protecting bone from damage. As we age, the human body is unable to regenerate damaged soft tissue (due to injury or everyday wear and tear) fast enough to keep cartilage, ligaments and tendons from deterioration. Over time, this deterioration can cause bone on bone articulations, leading to inflammation and pain. This is why supplementation is often recommended, to provide the body with the nutrients, primarily minerals that are typically lacking in high enough quantities from diet alone, to support the integrity of cartilage and joints.
How is it sold and how much do I take?
The average recommended daily dosage is approximately 9000 mg/day. Most companies recommend this dosage for a minimum of 30 days, lowering the dosage to about half this for maintenance from that point on. Shark cartilage can be found as a supplement in either powder or capsule form, commonly found around a 750 mg/capsule dosage. Do not take shark cartilage if you are pregnant or breastfeeding, or if you already have high blood calcium levels (hypercalcemia). Although shark cartilage is very safe for most individuals, some side effects such as nausea/vomiting, constipation, dizziness, low blood pressure, and high blood sugar, have been reported.
