We’re taking a closer look at the ingredients inside Flex+, Kollo Health’s targeted joint support formula.
If you like training, running, or just staying active, the last thing you want is stiff, uncomfortable joints holding you back.
So if you’re starting to notice little niggles, or bigger ones for that matter, a joint support formula is probably worth adding to your supplement stack.
Flex+ from Kollo Health is designed for exactly that, aiding joint comfort, mobility, flexibility, and range of motion with a formula built around clinically studied actives.
And if you use our Kollo Health discount code GF15 at checkout, you can save 15% on the first month of your subscription.
So let’s look at what’s actually inside this joint support formula and why each ingredient has been chosen.
Meet Flex+
Flex+ is Kollo Health’s daily joint support formula, made for people who want to keep moving comfortably as they train, stay active, and get older.
You take two capsules a day with water, and they can be taken morning or evening, with or without food, so it’s super easy to fit into your day.
But what makes Flex+ more interesting is the way Kollo Health has put it together.

Instead of using a standard capsule, Flex+ deploys first-of-its-kind dual-capsule technology. Basically, that means there’s one smaller capsule sitting inside a larger liquid-filled capsule.
This helps keep different active ingredients separate until you take them, which can support freshness, stability, and proper delivery.
It also means Kollo can combine complementary ingredients into a single daily formula, without you needing to mix powders or take scores of different supplements.
What’s Inside This Joint Support Formula?
So, what’s actually inside those clever little capsules?
Flex+ brings together two clinically studied joint actives, plus black seed oil, vitamin D3, and vitamin K2.
It’s a short ingredients list, but each part has a clear role, from supporting joint comfort and mobility to helping maintain normal bones and muscle function.
Here’s what each one brings to the table (and your joints).
Univestin® and AprésFlex®
Univestin® and AprésFlex® are the two main joint actives in Flex+, and chances are you’ve never heard of them before.
So here’s what they are and what they do.
Univestin® is a clinically studied botanical blend made from Acacia catechu and Chinese Skullcap, included to support joint comfort, flexibility, and mobility.
Then you’ve got AprésFlex®, which is a premium Boswellia serrata extract.
Backed by multiple clinical studies, it’s been selected to play a similar role, working alongside Univestin® to help keep you moving comfortably every day.
Black Seed Oil, Vitamin D3, And Vitamin K2
Alongside Univestin® and AprésFlex®, the Flex+ joint support formula also includes black seed oil, vitamin D3, and vitamin K2.
Black seed oil, also known as Nigella sativa, is naturally rich in thymoquinone and adds an antioxidant edge to the formula.
Then you’ve got vitamin D3, which contributes to the maintenance of healthy bones, normal muscle function, and optimal immune function.
Much like vitamin D3, vitamin K2 is also hailed for its ability to strengthen bone density.
So alongside the main hero ingredients, you’ve also got extra help for the bones and muscles that keep you moving with freedom.
Final Thoughts
Flex+ is a great option if you want to support your joints with something that feels more targeted than a basic everyday supplement.
You’ve got the two main joint actives in Univestin® and AprésFlex®, the added support from black seed oil, vitamin D3, and vitamin K2, and the innovative dual-capsule design that makes Flex+ stand out.
Adding it to your routine is straightforward, too. You just take two capsules with water, morning or evening, with or without food.
