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

Flex+ is designed to support joint comfort, flexibility, and everyday mobility, helping you stay active and move comfortably over time.

It’s ideal for people who:

  • Experience stiff or uncomfortable joints
  • Live an active or on-the-go lifestyle
  • Want to support long-term movement and joint health
  • Are training, walking regularly, travelling, or simply aiming to stay mobile as they age

Flex+ works gradually and consistently, supporting joints as part of a healthy, active lifestyle rather than offering a short-term fix.

Flex+ uses an advanced dual-capsule system to support optimal delivery and absorption of its ingredients throughout the day.

  • The inner capsule contains clinically studied plant extracts (Univestin® and AprèsFlex®) commonly used to support joint comfort and flexibility
  • The outer capsule contains fat-soluble nutrients (black cumin seed oil, vitamin D3, and vitamin K2), supporting bones, muscles, and overall movement

By separating these ingredients, Flex+ is designed to support effective absorption without unnecessary fillers - it’s joint support that’s thoughtful, targeted, and built for real life.

Flex+ is suitable for men and women and is designed for long-term daily use.

It’s:

  • Vegan-friendly
  • Gluten-free
  • Made without unnecessary additives

Flex+ can be taken year-round as part of your regular wellness routine and works well whether you’re highly active or simply focused on maintaining comfortable movement day to day.

For best results, take one capsule twice daily with food - one in the morning and one in the evening.

Consistency is key. While individual results vary:

  • Some people notice improvements in comfort and flexibility within a few weeks
  • Ongoing benefits typically build over time with regular daily use

Flex+ is designed to support long-term joint care, so continued use helps maintain mobility and movement as part of an active lifestyle.

    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.
