TSI manufactures an extensive range of glucosamine ingredients, allowing formulators to choose between shellfish and non-shellfish as well as supplement grade, food or pharmaceutical grade specification – to suit specification requirements. All glucosamine ingredients are available in N-Acetyl, HCL and Sulfate forms.

We also offer a broad spectrum of clinically proven, efficacious chondroitin sulfate ingredients under our PUREFLEX® brand, to service our partners in the Japanese market. To assure quality and purity, all of our chondroitin and glucosamine ingredients are manufactured in-house at our cGMP certified facility.

TSI offers several botanical extracts that are manufactured in our state-of-the-art extraction facility. These products include our branded Opteava® Green Tea ingredient line as well as our Ginkgo 24/6/5® Ginkgo Biloba ingredients. All TSI botanical extracts are manufactured to maximize purity levels while optimizing the beneficial elements that are inherent in the natural plant.

TSI is also the exclusive distributor of the proprietary BetaTOR® ingredient - a pure, free acid form of HMB (beta-hydroxy-beta-methylbutyrate). This innovative sports nutrition ingredient recently received approval from the Japanese Ministry of Health and can now be formulated into finished dose products for Japan’s emerging sports market.
