Kollo Health launches Flex+ Advanced Joint Support with dual-capsule delivery system

UK wellness brand Kollo Health is diversifying beyond liquid collagen products with the launch of Flex+ Advanced Joint Support on its online webshop. Featuring a dual-capsule delivery system, the supplement contains AprèsFlex, a clinically studied Boswellia serrata extract for joint comfort and mobility produced by PLT Health Solutions. 

The dual-capsule design creates what Kollo details as “two capsules, one advanced system” that combines clinically studied joint ingredients with nutrients supporting bone and muscle function.

The inner capsule contains Univestin and AprèsFlex, two joint-support ingredients backed by human clinical research. The outer capsule contains vitamin D3, vitamin K2, and black cumin seed oil to support bone and muscle health.

“Kollo customers have long used our collagen products to support connective tissue health and recovery,” says Jenni Falconer, founder at Kollo Health, adding that Flex+ represents a natural evolution of the brand’s wellness platform.

“With Flex+, we wanted to go further by introducing clinically studied joint ingredients in a system specifically designed to support mobility and everyday well-being. The dual-capsule format allows us to deliver complementary nutrients in a structured way that reflects how the body actually supports joints, bones, and movement.”

Low-dose mobility benefits

Kollo enters the science-backed joint support category, targeting consumers seeking more comprehensive musculoskeletal health solutions.

Flex+ Advanced Joint Support.Four clinical studies demonstrate AprèsFlex mobility benefits. The patented extract is standardized to 20% AKBA (3-O-acetyl-11-keto-β-boswellic acid), the boswellic acid most closely associated with joint-support activity.

Across four randomized, placebo-controlled human trials, supplementation with AprèsFlex 5-Day Joint Support has demonstrated rapid improvements in joint comfort within five days.

The ingredient was also associated with improved mobility and joint flexibility, enhanced physical performance measures, and support for healthy inflammatory balance in joints.

AprèsFlex is also known for its low clinically studied dose of only 100 mg per day, making it an efficient joint health support ingredient available to formulators.

“Unlike conventional Boswellia extracts that often require higher doses and extended supplementation periods, human clinical studies have shown that AprèsFlex can deliver significant improvements in joint comfort and physical function within just five days,” highlights Kollo.

Nutritional interventions for mobility

Kollo underlines that supporting the health of cartilage for cushioning joints and smoothening movement is an important component of maintaining long-term mobility and independence. It adds that nutritional strategies that help support healthy cartilage and joint comfort are becoming an important part of healthy aging routines.

The most recent clinical study on AprèsFlex expanded beyond pain and mobility endpoints to explore the ingredient’s effect on structural joint health, including cartilage.

The study used MRI imaging analysis to evaluate cartilage integrity — including thickness, composition, and overall damage scores — alongside related structural features within the joint.

Subjects receiving AprèsFlex demonstrated favorable changes in cartilage-related MRI endpoints, including preserving cartilage thickness, slowing the loss of joint space, and slowing the processes that wear down cartilage.

According to Kollo, these findings suggest that AprèsFlex can extend benefits beyond short-term comfort and mobility to include support for healthy aging.

“Kollo has built a strong following around premium collagen products,” says Steve Fink, VP of Marketing for PLT Health Solutions. “The collaboration highlights the growing convergence of lifestyle wellness brands and clinically substantiated ingredients.”

“With Flex+, they are extending that platform into clinically supported joint health. By incorporating Après Flex 5-Day Joint Support into an innovative dual-capsule system, they are bringing together fast-acting joint science with a format that reinforces their commitment to thoughtful formulation.”

Last March, PLT Health Solutions released a clinically backed ingredient, Kinexa Joint Longevity Complex, designed for lasting, foundational joint strength support. The ingredient is backed by a clinical study demonstrating how it improves the health of multiple joint structures.
