Our top GlycanAge questions from our readers, answered
What is the GlycanAge test price? What do GlycanAge tests report?
GlycanAge test kits are priced in British Pounds at £289 for a single test. That price drops to £246 with our 15% discount code. Further savings are possible by purchasing two kits (just £209 per kit with our discount code!).
Each test kit comes with a consultation with a GlycanAge ‘healthspan’ doctor, who will help you go through their detailed health report and help you interpret recommendations for improving your biological age result.
Is GlycanAge legit?
GlycanAge is well established and highly reputable company with many thousands of satisfied customers. Nick has worked directly with their team on multiple projects, including on Reversed: The Race for Longevity docuseries (pictured on set!), and regularly re-tests his biological age with them.
There are 300+ research studies backing the biological age test and health reports.
Who is the Founder of GlycanAge?
GlycanAge was Founded by Gordan and Nikolina Lauc, and Nikolina currently serves as the GlycanAge CEO. We have interviewed both of them in our technology articles, read them here! Interview with Nikolina. Interview with Gordan.
What is the most accurate biological age test? Is it GlycanAge?
The answer to which biological age test kit is ‘most accurate’ is not straight forward. However, in 2023 Nick tested over a dozen biological age tests and chose the best three for the A Longer Life audience. We are happy to share the GlycanAge was one of the top three.
The GlycanAge biological age test is the best in its class for assessing inflammation driven aging in your body, as the glycans track what govern inflammation in the body.
How often should you test your GlycanAge?
We asked GlycanAge Chief Science Officer Professor Gordan Lauc: What is the timescale on which our GlycanAge is changing?
His response: Glycans change relatively slowly. The half life of IGG is approximately three weeks. I think the shortest period to see something would be maybe a month. But this is for a really radical change. If you start taking a drug, or really changed lifestyle factors a lot, such as completely changing diet, starting to exercise much more.
Normally, we see things changing after three or four months. If you slightly change your diet today, it first takes some some time to manifest in the glycans. Normally, we recommend people when they change a lifestyle, re-test after three months and then six months again. If what you are doing is working, you will see the result.
