Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.
2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Osteoarthritis
Refer to label instructions
Taking collagen hydrolysate may help relieve pain associated with osteoarthritis of the hip and knee.
In a double-blind study, collagen hydrolysate was compared with gelatin and egg protein as a treatment for osteoarthritis of the hip and/or knee. When subjects took 10 grams per day either of gelatin or collagen hydrolysate for two months, they reported significantly more pain relief than when they took a similar amount of egg protein.5 More research is needed to confirm the benefits of gelatin or collagen hydrolysate in OA.
How It Works
How to Use It
Bovine cartilage is typically recommended at 3 grams three times per day. Shark cartilage is sometimes taken in much higher amounts (e.g., 60 to 100 grams per day orally or by enema). These amounts are based on animal and anecdotal evidence and their safety and efficacy have not been confirmed by controlled clinical trials. Not only is toxicity information on this amount of shark cartilage lacking, but the amount of calcium in this amount of shark cartilage exceeds the 2 to 2.5 grams per day that is commonly considered to be the upper limit of safe intake. Type II collagen, when used for its effects on the immune system in rheumatoid arthritis, is used in very small amounts, from 0.02 mg to 10 mg per day. Gelatin and collagen hydrolysate is recommended at 7 to 10 grams per day.
Where to Find It
Cartilage is derived from either sharks or cows. Collagen is derived from either cows or chickens.
Possible Deficiencies
Since they are not essential nutrients, neither cartilage nor collagen are associated with deficiencies.

Interactions with Medicines
As of the last update, no reported interactions between this supplement and medicines. It is possible that unknown interactions exist. If you take medication, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a supplement with your doctor or pharmacist.
Side Effects
Side Effects
Reports have suggested that some people should not use a cartilage supplement. This concern is based only on theory, not clinical evidence. This would include those people with cardiovascular disease, women who are planning to be or are pregnant, nursing mothers, anyone having or having had surgery within 30 days, and athletes training intensely. None of these concerns have been proven in clinical trials, however. Because shark cartilage contains calcium, people who ingest large amounts of shark cartilage (60 to 100 grams per day) may be consuming excessive amounts of this mineral. However, no cases of calcium toxicity resulting from the ingestion of shark cartilage have been reported.
While use of gelatin, collagen hydrolysate, or type II collagen has not resulted in any reports of serious side effects, people with known sensitivities to chicken or beef should consult a doctor before using them.
