Will I trip balls?
Nope! The ingredients in our products are 100% legal and 0% psychedelic, they do not contain psilocybin or any other psychoactive ingredients. So drinking Seryni won’t make you see the spirits of your ancestors. Sorry if that was your goal. Maybe one day ;) With that said, psychedelics, especially magic superfoods, have proven to be helpful for people dealing with depression, PTSD, and a host of other issues. We thoroughly support the exploration of natural solutions to our problems, which is why we donate a % of our profits to Heroic Hearts, which connects veterans struggling with PTSD to psychedelic therapy retreats. (Psst, veterans still get a lifetime discount – email us!)

Is this a coffee replacement / Can I add this to my coffee?
Ultimately, the choice is yours, and we aim to support you in achieving your specific goals, whether it's reducing caffeine intake or enhancing your coffee routine with added benefits. Seryni is designed to be a coffee replacement with the benefits of functional superfoods and other nootropics, offering a delicious coffee taste with less caffeine and acidity. Most of our customers have successfully transitioned away from traditional coffee by using Seryni. For those looking to reduce their caffeine intake, we recommend having Seryni on its own. If, however, you're looking to keep drinking your traditional coffee while benefiting from the functional superfoods and nootropics in Seryni, you can try adding it to your normal cup of Joe.
