Joint health booster

OsteolTM is a natural ingredient which helps to boost standard joint health formulas (D-Glucosamine+ Chondroitin). In vitro and clinical studies confirmed its potential to target joint health.1

  • Natural ingredient made from bio-active milk proteins
  • Helps to boost standard joint health formulas
  • Strong scientific background (in vitro, clinical studies) Improve the efficiency of usual
  • Glucosamine + Chondroitin mix & consequently go further in joint health and cartilage preservation.

Scientific works showed

Nexira's R&D department has developed Osteol™, to boost standard joint health formulas (D-Glucosamine + Chondroitin). Extensive research work has shown that Osteol™ can:

  • Improve chondrocytes protection up to 95%1
  • Reduce inflammatory markers up to 92%2
  • Help to significantly reduce the feeling of discomfort by nearly 50% on volunteers with nascent dysregulated knee cartilage homeostasis3
  • Allow lower use levels of ingredients in joint health formulas4


1Preservation of Chondrocytes

Adding OsteolTM to regular D-Glucosamine + Chondroitin mix allows to increase from 25% to 95% the protective effect.

In vitro test: Evaluation of the effect of OsteolTMon chondrocytes preservation when stressed by inflammatory markers :


Up to 95% chondrocytes preserved by OsteolTM

Thanks to OsteolTM near than 95% of stressed chondrocytes are preserved from apoptose, against 25% obtained with the mix ( D-Glucosamine + Chondroitin), at the same concentration (1,01 g/ml).


These results, confirmed by others tests conducted on the same model, highlight the exceptional property of OsteolTM as a formula booster.

4Reduction of active dosage

In vitro study: Impact of OsteolTM on D-Glucosamine dosage, in relation with the protection of stressed chondrocytes



Scientific works showed that the synergic effect of OsteolTM combined with standard joint health formula (D-Glucosamine + Chondroitin) is correlated to the ratio [OsteolTM] / [D-Glucosamine].

(3) Clinical study (monocentric, randomized, placebo-controlled and in parallel double blind format) conducted on 57 volunteers, suffering from mild to moderate osteoarthritis of the knee, during 90days , and evaluating the effect of [Osteol™ + D-Glucosamine + Chondroitin] (2008).
