The product features AprèsFlex® 5-Day Joint Support, a clinically studied Boswellia serrata extract known for its low-dose, fast-acting benefits for joint comfort, mobility and physical performance.
The science-driven formulation combines AprèsFlex with undenatured type II collagen, hyaluronic acid, vitamin C, and manganese — nutrients selected to support cartilage structure, joint lubrication and connective tissue health. The new product features 100 mg of AprèsFlex, along with 40 mg of undenatured type II collagen (Nuvicol® II), 33.25 mg hyaluronic acid, 80 mg vitamin C, and 2 mg manganese.
According to Blanca Rodríguez, Managing Director of Grow in Health, the new product reflects the KumbreX brand's focus on combining performance nutrition with long-term musculoskeletal health.
"Mobility is one of the most important performance issues for athletes and active individuals," Rodríguez said. "Joint discomfort and stiffness can compromise training consistency, recovery, and overall performance. With GROW FLEX, we wanted to build a formula that supports both mobility and structural joint health so people can continue to move, train and perform at their best," she added.
The KumbreX brand focuses on science-driven solutions that support performance, recovery, and healthy aging, targeting mechanisms associated with inflammation, oxidative stress, and connective tissue integrity.
AprèsFlex® 5-Day Joint Support: Fast-Acting, Low-Dose Boswellia Innovation
AprèsFlex is a patented, synergistic Boswellia serrata gum resin extract. The oral bioavailability of the active component, acetyl-11-keto-beta-boswellic acid (AKBA), from AprèsFlex has been shown to be about 52% higher than other commercially available Boswellia extracts, allowing for a lower daily dose with improved efficacy in enhancing joint comfort, flexibility, functional mobility and cartilage health. Unlike conventional joint health ingredients, which often require higher doses and longer supplementation periods, AprèsFlex demonstrated significant improvements in joint comfort and physical function within just five days with a low 100 mg/day dose.
Across four randomized, placebo-controlled clinical studies, supplementation with AprèsFlex 5-Day Joint Support has been shown to support:
- Improvements in joint comfort within five days†
- Reduced stiffness, improved flexibility and better overall joint function†
- Enhanced physical performance metrics†
According to Steve Fink, Vice President of Marketing for PLT Health Solutions, Grow in Health's selection of AprèsFlex for their active nutrition product demonstrates a commitment to science-backed innovation. "When it comes to mobility, there can be a disconnect between what consumers want and what existing solutions deliver. Too often, natural joint and muscle health solutions require large doses that take weeks or even months to show improvements - and the science backing these ingredients doesn't support what consumers are looking for," he said. "With high quality clinical studies, AprèsFlex delivers on its promises. Today, AprèsFlex powers many of the world's leading joint health brands, helping active consumers and athletes stay mobile and perform at their best," he added.
