Safety Research
Acute Toxicity Test:
This test could not detect the half lethal limit (LD50) on mice. No tested animals died after given the maximum dosage which is equivalent to 540 times over adult daily maximum dosage (converted according to weight of human beings and mice). These results showed the high clinical dosage safety.

Long-Term Toxicity Test:
Rats were given 4, 8 and 16 times over an adult daily clinical dosage (dosage converted according to body surface area of human beings and rats) continuously over a long period of time, and no toxic reactions were found. The observations of weight changes, hematology, hemobiochemistry, organ coefficients calculation and histopathological examination of the important organs were performed; No pathological changes related to OsteoKing were found. The results showed that long-term use of OsteoKing is safe.

Analeptic and Anesthetic Test:
The tests performed by the National Analeptic and Sports Nutrition Inspection and Research Center showed that OsteoKing does not contain any analeptic and anesthetic.

Tests of Heavy Metals and Harmful Elements:
The tests were done by Iowa University in the U.S. and Hong Kong Standards and Testing Center of the Department of Health, the results indicate that OsteoKing is in accordance with the international standards.
All these tests indicate that OsteoKing is safe and reliable.
