    Sorted my Tennis Elbow

    I’ve had tennis elbow for years and have been taking Nurofen all the time just to manage the pain. I saw Flex+ on Instagram and thought I’d give it a try as nothing else had really fixed the problem.

    Within about a week, the pain had noticeably reduced and my elbow felt much better during the day. I was genuinely surprised as I wasn’t expecting it to work this quickly.

    I’m actually really impressed so far and will definitely continue taking it as long as it keeps working.

    Super good

    I was lucky enough to be sent a months supply to try and I’m really impressed. Easy to take, tastes good and I’ve noticed a difference in my skin elasticity already. I think it’s pricey but it seems that to get a decent collagen that actually does what you want it to, you have to spend a few quid.
