SUPPORT FOR THE WEAR AND TEAR OF DAILY LIFE

Joint discomfort doesn’t just come from injury, it builds over time through training, repetition and everyday movement.

Flex+ is formulated to support joints affected by high-impact activity like running, repetitive strain such as tennis or golf, and the natural wear and tear associated with ageing.

Using clinically studied ingredients, it helps support the body’s response to inflammation, a key factor linked to stiffness, reduced mobility and joint discomfort.

Ingredients like AprèsFlex® and Univestin® have been researched for their ability to support joint comfort, flexibility and movement in as little as 5–7 days.

Whether it’s training load, active lifestyles, or age-related joint changes, Flex+ is built to support your joints so you can keep moving.

Frequently Asked Questions

Yes — the collagen powder and Flex+ work well alongside each other in one simple daily routine. Many customers take their collagen in the morning mixed into a drink, and their Flex+ capsules with a meal. There's no overlap between the two, and they complement each other particularly well — collagen supports the structural integrity of skin, hair and connective tissue, while Flex+ targets joint inflammation and discomfort directly at the source.

Noticeable improvements in joint comfort and mobility have been reported in as little as 5–7 days. Flex+ uses two clinically studied active ingredients - AprèsFlex® Boswellia and Univestin® - backed by 25 clinical studies. As with any supplement, consistent daily use delivers the best results over time.

Customers report significant improvements in skin appearance - including reduced wrinkles and improved elasticity - in as little as 4 weeks when taken daily. Each sachet delivers the full 10,000mg clinical dose of Naticol® marine collagen with 100% NRV Vitamin C, which plays an important role in collagen synthesis. Consistency is key to seeing results.

    Helping with my old man neck

    I'm now at the 4-month stage of taking kollo daily and my neck discomfort is improving. As a 44 year old getting told you have arthritis is pretty annoying but it's been the kick I needed to take action, and Kollo has been a big part of my plans. It will be a forever part of the morning routine.

    The hydration sachets are great too, when my wife isn't stealing them.
