Woman in her 30s, working at an advertising company
When I got home, I took a cube out of my bag and had one on the couch.
By the time you start preparing dinner, you'll have naturally switched from "work mode" to "personal time."
Another thing I like about it is that it contains no sugar so I can continue to drink it without feeling guilty. -
Male sales manager in his 40s
Even if you get home late, just put a few drops of liquid in your mouth and you'll naturally shift from work mode to relaxation mode.
Even the time before my alarm goes off the next morning feels calmer, and I've recommended it to my colleagues too. -
Woman in her 60s, full-time housewife
Taking it with herbal tea every night has become a nightly habit, helping me feel calm before going to bed.
The great thing about capsules is that you can continue taking them without having to worry about the taste or smell.
The fact that it is plant-based and contains no additives gives you peace of mind that makes it a product you'll want to use for a long time.
