what does j1a stand for?
The name comes from the Portuguese word dia, meaning "day." J1A represents the phrase "mais um dia" — one more day.
One more day. One more walk. One more workout. One more healthy choice. One more conversation. One more chance to try again.
J1A was born from that philosophy.
Our mission?
J1A exists to help people feel their best—physically, mentally, and emotionally—through the small choices that shape everyday life.
the founder?
Hi, I'm Green Juice Mami, founder of J1A.
I'm a 25-year-old entrepreneur from Boston with a passion for wellness, education, and understanding the connection between what we consume and how we feel.
My journey into health began after losing my dad to COVID in 2021. What started as an interest in nutrition eventually expanded into studying nervous system regulation, neuroscience, behavior change, and the ways everyday habits influence our energy, mood, focus, and overall well-being.
That curiosity became J1A.
What began as a simple juice company evolved into a larger mission: helping people better understand the relationship between nourishment, performance, and the nervous system. Through functional beverages, educational workshops, and lifestyle products, J1A exists to make wellness feel approachable, practical, and rooted in science.
