05Why DEL&Co.
Year 2021. Four directions. One brain.
Four employment contracts at the largest financial group in Bulgaria — all at the same time. An Italian restaurant. The tourism business. An organic products store.
My brain was working non-stop — until it stopped obeying me.
"What if I created something that really works — not because the label says so, but because it’s been proven?"
…it took me five years to find the answer.

01
Created out of personal necessity
"If you want to eat quality prosciutto, you open your own restaurant." I wanted to know exactly what was in it and to have it myself every day.
02
Science first, formula second
Only researched dosages, human clinical trials, and premium-grade ingredients. No placebos.
03
2formulas
Two roles, not one formula
DAY is not a caffeine-free BOOST, and BOOST is not just a stronger DAY. Two independent formulas for different tasks.
04
Not just for today
Focus and mental energy matter today. But the brain you will rely on in years to come — matters too.

10Long-term
The brain changes throughout life.
Some cognitive abilities change as early as adulthood. Information processing speed, working memory, and attention do not remain the same throughout life. Therefore, brain care is not a topic for "sometime later."
