Health Optimisation Summit Reviews 

I have multiple learning disabilities, autism, ADHD, and dyslexia. I also have chronic fatigue. I brought an early bird ticket last year, and was looking forward to attending, and then I realised there would be 4.5K people there, which would be hugely overhwleming. I asked for a refund, and explained my situation. They would not offer me a refund or supply a way of reselling my ticket. Considering they are a Health Summit and make no considerations for the issues and challenges I face, it looks like I'm now going to loose £199 which considering I can't work is not something that I find easy to stomach. They have effectively stolen my money. It's shameful, and completely incongruent of who they say they are.

My favorite health conference. I've been 3 times, and will attend again this year in London. Highly recommend.

The Health Optimisation Summit is the most incredible event for anyone who has any interest in their health. Amazing exhibitors, incredible speakers, fantastic opportunities to meet like-minded people. It’s an event not to be missed!

HOS is THE health event of the year in London. It’s so nice to see the EU community come together. Tim and the team put on the perfect balance of speakers, vendors, food and space. It’s easy to meet fun open hearted people interested in getting nerdy on health. I always learn something new.

HOS is always an exciting event to attend, and very well organised. The stellar lineup of speakers and the top-class brands who exhibit at HOS make it unmissable for anyone interested in biohacking and improving their health & wellness.

I’ve attended the Health Optimisation Summit in both London and Austin, and I can genuinely say it is the most comprehensive health and wellbeing event I’ve ever experienced and I've been to many.

The quality of the speakers is exceptional. You’re hearing from some of the most knowledgeable, forward thinking and inspiring people in health, longevity, performance and wellbeing, alongside an incredible range of exhibitors bringing genuinely innovative products, ideas and technologies into one place.

But what makes this event particularly special is the community that has grown around it. There’s an energy that you simply don’t get at most conferences. People actually connect, share ideas and build relationships, relationships that have become genuine friends for life.

London and Austin have both been outstanding experiences, and each time I leave with new knowledge and some incredible product/gadgets and supplements.

Not one to miss!

This is one of the most important expos you can visit in current times. Increase your health, vitality and longevity. Really well ran with a fantastic crowd and a list presenters. A must attend.

Life changing experience! Since I went to this event literally changed my habits.

Started drinking electrolytes, wearing blue blocking glasses at night. Got my sleep in check.

Also I found out that I had low testosterone which I never thought about. I work out more, dropped my body fat, feeling better than ever.

It’s a great event that opens your eyes in so many ways. If you are into health it’s for you but if you are not into health it’s even more for you.

I had no idea about health optimization, and it literally kickstarted my journey!

If you’re looking for the latest innovative health solutions, you’ll definitely find them at the London Health Optimisation Summit. The organisers are genuinely passionate about the industry, and it shows. The atmosphere is lively and welcoming, making it easy to learn from inspiring speakers while browsing and trying out cutting-edge products for ongoing optimal health and living. It’s fun and engaging

One of the best health & wellness events I have been to, and so extremely well organized, nothing is left to chance. I went there first time in 2023 with a general ticket and was amazed by the mix of exhibited products, speakers and workshops. In 2025 I went again but with a VIP ticket and have to say it was more than worth it, especially for networking in the space. I can highly recommend this event for everyone - no matter if for business or personal interest.
The only "suboptimal" part is, that there is always such an amazing offer of things to do or people to listen to, that it is really hard to choose what to prioritize ;)

I have attended and spoken multiple times. Every year it is bigger and better. Transformative. Tim has his finger on the pulse of everything new and interesting in health Optimisation and you will get it all here. A must attend.

This is an EPIC event! do not miss it.

The energy and excitement at the Health Optimisation Summit are amazing. There’s always a fantastic line-up of speakers, and it’s great to discover the latest health technology, gadgets, and supplements on offer.

It’s an inspiring event with so much to see, learn, and experience. If you’re thinking about attending just one health and longevity event this year, the Health Optimisation Summit has to be the one!

This is a great event with amazing speakers, great exhibitors and a lovely community eager to share knowledge.

Having attended the world’s leading biohacking and performance events as a speaker, exhibitor and attendee, I consider the Health Optimization Summit the global benchmark.

London and Austin bring together cutting-edge technology, world-class minds and a community driven by shared knowledge rather than a hard sell. Tim Gray lives the lifestyle he promotes, and that authenticity runs through the entire experience.

For anyone serious about biohacking, longevity and human performance, I always tell them that HOS is the event to attend on either side of the Atlantic.

The best curation of brands and speakers you’ll see, but not only that, a room full of growth minds to connect and learn from. Unmissable for me. The retreat the team put together was also one of the best event experiences I have ever had

This event is the easy peasy go-to for anyone interested in health, longevity, and all things biohacking. I have made sure not to miss an edition since 2022. The event is packed with the latest in medical screening procedures, supplements, science-backed protocols for health, fitness, focus, beauty, and general wellbeing. The speakers are all top of the range and not just from Europe. Their VIP package is, for a change, actually worth it, incredible gala dinner with all the speakers, private space with extra gizmos, tech, and chilling areas. The curation is clockwork dialled in with maniacal detail. The dedicated networking spaces and cool side events create many opportunities for meaningful conversations and collaborations. It feels less like a conference and more like a community of people genuinely interested in advancing the future of health.

I'll certainly be back.

Always look forward to this event every year, it’s the 4 year that I’ll be going, met many like minded people and friends at the event. Some of the most innovative brands exhibit there so you can try some cool stuff and amazing speakers. The vip event was also very well organised in the Shard, awesome spot!

Highly recommended

Best health event, hands down. I’ve been every year either as an attendee or exhibitor and can’t wait for the next show.

HOS and Tim have been an inspiration for creating Healthy Horizon in Lisbon. Thank you for creating this and continuously pouring your love and energy in this project.
