In 2016, when Dorothée and I founded Thrivous, our focus was on cognitive enhancement. For years, I had been analyzing the science of nootropics, experimenting, and applying what I had learned. Dorothée noticed my friends regularly asking me about nootropics. And one day, pointing at all my supplement bottles, she commented that we should start a nootropic business. Over the next couple years, we developed and brought to market four excellent nootropic supplements. Clarity was first, designed to enhance memory and focus. It was followed by Serenity and Surge, respectively for sleep and energy. And finally, we launched Alpha, designed to enhance brain and nerve function for healthy aging. Alpha is an excellent nootropic, packed with science-backed nutrients for the brain. But it’s also more than that. It's also a geroprotector, a supplement designed to promote healthy longevity — particularly for brain function. With Alpha on the market, we recognized that it would make sense for Thrivous to offer complementary geroprotectors. So, in 2018, we began development of three additional geroprotectors. Omega is designed to enhance heart function and circulation. Tenacity is designed to enhance joint and bone function. And Vitality is designed to enhance metabolic and cellular function for better aging. By 2019, Thrivous had the full line of geroprotectors on the market. And Dorothée and I began taking them nearly every day — often more than once per day. After all, we designed them as much for ourselves as for anyone else. And, although we couldn’t “feel” it right away, that’s when the magic began. Fast forward to 2023. Dorothée and I have been using Thrivous geroprotectors consistently for four years. I take two servings of each geroprotector with lunch, and sometimes another two servings with dinner. Dorothée does about the same. We also both started intermittent fasting in 2021, so we generally don’t eat breakfast. Measuring Our Biological Age A few months ago, Dorothée and I both used Thrivous Clock to measure our biological age. Biological age is different from chronological age. The latter is just how old you are as measured by the number of times you’ve flown around the sun. Biological age is a measure of how the health of your body compares to that which is typical of other humans of a given age. So, for example, if you’re particularly healthy, your biological age might be lower than your chronological age. And, conversely, if you’re unhealthy, your biological age might be higher. Various factors influence your biological age. Notably, there are several factors over which we have significant control, such as exercise, sleep, and diet. Thrivous Clock requires a simple blood test, which provides biometrics required for a PhenoAge calculation. PhenoAge is the most cost-effective open source science for calculating biological age. It’s based on the research of scientists such as Morgan Levine. One of the useful things about the PhenoAge calculation is that it’s fairly easy to apply retrospectively. In other words, if you’ve collected biometrics from bloodwork over the years, you can go back and see whether you have the inputs needed for PhenoAge. And, if you do, you can calculate changes to your biological age historically. While waiting for our Thrivous Clock results, that’s what Dorothée and I did. We plugged our old biometrics into the free PhenoAge calculator on the Thrivous website. Then we put the results into a spreadsheet and graphed them over time, up to the year 2019. As it turns out, Dorothée had been aging better than I had. In 2019, her biological age was tracking about seven years younger than her chronological age. And my biological age was just about normal for my chronological age. She kind of lovingly bugged me about that. Then I got my Thrivous Clock results. Boom! I was excited to see, after graphing my 2021 and 2023 test results, that my biological age had decreased by seven years since 2019! It confirmed, ...
