New Study shows TamaFlex® works in 5 Days!

All clinical human trials supporting joint health were performed with healthy subjects with joint discomfort caused by physical activity. In a randomized, double-blinded trial, 90 healthy adults took TamaFlex® or placebo twice daily for 90 days. The study showed:

TamaFlex® effectively improved joint health by reducing joint discomfort and stiffness, leading to improved physical function in healthy subjects with joint issues caused by physical activity.

TamaFlex® 250 mg and 400 mg significantly increased distance walked (6MWD), reduced both Stair Climb Time and Pain Scores measured by the Visual Analog Scale and VAS, WOMAC discomfort, stiffness, and physical function scales when compared to placebo.

TamaFlex® significantly improved knee flexion – the amount the joint can move and flex - measured using goniometer and physician global assessment score.

TamaFlex® provided significant benefits as early as 14 days of supplementation.

No serious adverse events were observed with TamaFlex®.

"More effective than glucosamine/chondroitin, because few users report real relief, whereas TamaFlex® shows significant relief compared to placebo."
