It is an honor to have been part of a talented Slovak research team studying isothiocyanates over half a century ago. I had the privilege of contributing to the discovery of sulforaphane and its anti-cancer properties. During my active career at the faculty and in various international laboratories, I conducted numerous experiments, many of which focused on researching isothiocyanates, including sulforaphane. My goal was to uncover their remarkable potential and apply them in health prevention. Unfortunately, I didn’t have the resources to fully realize my vision and translate experimental findings into practice.
Even in retirement, sulforaphane kept “finding” me. I collaborated with American scientists and suggested the development of a two-component nutraceutical, which significantly improved sulforaphane absorption. Since sulforaphane was unavailable in Slovakia, the company CarnoMed decided to produce its own product and invited me to collaborate—a proposal I gladly accepted. Near the end of my professional journey, I had the opportunity to use my expertise to accelerate and guide the production process of this product.
I am immensely grateful for the chance to witness global scientific efforts to unveil sulforaphane’s secrets. Never in my dreams did I imagine being involved in bringing Sulforaphane Extra to the market. In February 2020, the product was launched and made available in Slovakia. Since then, I have been taking one capsule daily for long-term preventive use and have gained the following insights.
From the outset, I can state that throughout my use of sulforaphane, I have experienced no adverse effects. One of the most noticeable benefits reported by users is the reduction of chronic inflammation and relief from pain, often within two to three weeks. I can confirm these results personally. My sleep quality also improved significantly, a benefit that continues to persist with prolonged use.
The most remarkable and unexpected benefit of sulforaphane, however, has been its effect on my pancreas. In 2020, I was diagnosed with chronic pancreatic insufficiency, pancreatic atrophy, and other age-related conditions. After 2.5 years, I underwent another abdominal ultrasound. To my astonishment, my gastroenterologist reported a normal pancreas, liver, gallbladder, spleen, and kidneys. He asked, surprised, what I had been doing to maintain such good health, adding: “If I didn’t know your age, I’d estimate you to be at least 30 years younger.”
I did not change my diet or exercise habits. The only significant change was the long-term use of Sulforaphane Extra. My experience also highlights its role in supporting immunity. For instance, I recently attended a lunch meeting with a guest who unknowingly had COVID-19. The next day, his entire family fell ill, but I remained healthy. He later called, amazed by my resilience, and exclaimed, “You must have an incredible immune system!” I attribute this to sulforaphane’s support.
When I stopped taking sulforaphane for 4–5 weeks, I began to feel pain in areas where I had previously injured myself. This served as a clear signal to resume supplementation, after which the discomfort subsided.
I am deeply grateful for sulforaphane’s role in improving my health and immunity. Its benefits, as I have experienced, are both profound and life-enhancing.
