What is TamaFlex®?

It is estimated that over 72 million American adults struggle with joint aches and discomfort. Adding to the problem: joint comfort treatment options are limited, not designed for long-term use, and may come with side effects. TamaFlex® is the first plant-based blend of Tamarind Seed and Turmeric Root Extracts clinically proven to provide fast-acting and long-lasting joint relief. Clinical results in healthy subjects show TamaFlex® is safe and effective in improving joint health, stiffness, and mobility.

Target Audience

TamaFlex® delivers fast-acting and long-lasting joint relief that can benefit anyone desiring healthy joint function, including athletes of any level, anyone experiencing joint soreness, and aging active adults.

Active/Sports Nutrition

Active/Sports Nutrition

Joint health is a complex issue for everyone, but for athletes, years of physical activity can take a toll. The constant strain on the joints from intense training sets the stage for joint wear and tear. TamaFlex® improves joint flexibility, supports a healthy inflammation response, and soothes soreness due to activity, and can help get athletes back to training faster.

Joint and Tissue Health

Joint discomfort due to activity is often a result of normal wear and tear off connective parts within the body. Other contributing factors include: weight, which puts more pressure on joints, especially knees, hips, and feet; sedentary lifestyle; and poor eating habits. TamaFlex® boosts joint flexibility, provides fast-acting and long-lasting relief, and helps protect cartilage and connective tissues.

Joint & Tissue Health
Aging Active Adults

Aging Active Adults

An issue facing today’s active population is more than 55 percent of men and almost 70 percent of women may be experiencing a discomfort and problems due to moving, walking, exercise and daily activities. Unfortunately, the treatment options for relieving joint discomfort are often ineffective and do not provide adequate relief. The natural ingredients in TamaFlex® have been clinically shown to make a significant difference in improving joint health.

How it Works

TamaFlex® is the market’s first patent-pending, plant-based synergistic blend of Tamarind Seed (Tamarindus indica) and Turmeric Root (Curcuma longa) Extracts that have been clinically shown to promote both fast-acting and long-lasting joint comfort. By helping to modulate both the COX-2 and 5-LOX enzyme pathways, TamaFlex® helps balance normal healthy inflammation, resulting in significant improvement in joint comfort and function. It also delivers antioxidants that help to protect cells and tissues.
